HOW THE BEASLEY SPLIT SOLAR HOT WATER SYSTEM WORKS
PRINCIPLE OF OPERATION
The secret to the efficiency of a split system is maintaining stratification within the tank. Beasley tanks are designed to efficiently return the solar heated water to maintain stratification and therefore maximise the useful quantity of solar energy.
The Beasley split solar hot water system uses a pump to circulate the potable water around the solar collectors. To ensure hot water is not circulated into solar collectors at a lower temperature, an electronic differential controller monitors the cold and hot sensor connections, only running the pump if the water in the solar collectors is significantly hotter than the temperature of the water in the storage tank. A non return valve is also fitted next to the pump to ensure a thermo-syphon cannot be set up to transfer hot water in the storage tank up to the cold solar collectors.
To ensure the solar collectors are protected from frost in extremely cold weather conditions, the differential electronic controller monitors the temperature of the hot sensor and will start the pump for a short period to raise the solar collector temperature enough to prevent frost forming in the solar collectors.

PUMP CIRCULATION SYSTEM
The circulation system basically comprises an electrically driven centrifugal pump, a fully programmable electronic temperature differential controller and a hot and cold temperature sensor lead. The leads have thermistors located at one end and at the other, connect to the differential controller. The hot sensor is situated in a pocket inside the return port of the solar collector and the cold sensor is attached directly to the cold inlet pipe to the pump. The inlet of the pump is teed into the cold inlet pipe work which is located in a weather proof cover fastened to the outer casing of the tank. The differential controller and electrical connections are also located with in the cover. A non return valve is fitted on the pressure side of the pump to prevent the system from thermo-syphoning in cool conditions. A restrictor is located in the same line to moderate the pump flow rate. The differential controller can be individually programmed to suit the climate of the system location.

As the sun heats the water in the panel, the hot sensor detects a temperature change and the controller compares this reading with that of the cold sensor. If the temperature differential is greater than 9degC the controller will start the pump.
Cold water from the bottom of the tank is circulated through the panel and back into the tank through the solar return port located approx 1/3 of a way up the tank. When the warm water has been collected, the hot sensor will no longer detect a significant temperature differential and the controller will stop the pump. On a sunny day, the pump will run virtually continuously until the cold sensor detects water at 65°C. The pump will then be shut down as the tank is now be filled with hot water.
Frost protection of the solar collectors is achieved automatically by the electronic controller which is set to switch on the pump when the ambient temp falls to 3°C. A small amount of water from the tank will be circulated through the collectors until the hot lead senses that the temperature has reached 7°C. At this point the controller will switch the pump off.

Getting the most from your Beasley solar hot water system
Installation must comply with all national and local electrical and plumbing codes
LOCATION
The performance of any solar hot water system can be significantly influenced by the way that the system is set up and used.
For maximum solar contribution:
• Solar collectors should be facing between north-east and north-west. • Collectors should be inclined between 15° and 35°. • There should be no shade over the collectors.
For optimum performance the storage cylinder should be installed to face the equator (south in the Northern Hemisphere, north in the Southern Hemisphere). Deviation from the equator up to 45° east or west has little effect on total annual solar contribution (approximately 4%). Should it not be possible to face the equator, the decision of either an EASTERLY or WESTERLY bias must be made:
• If major hot water draw is before 2 pm favour EASTERLY, or • If major water draw is after 2 pm favour WESTERLY. • The westerly direction is more commonly used. The storage cylinder should be installed on a roof of pitch or
angle that is the same as the latitude angle of the site. Roof angles within 20° of the latitude angle will have little effect on the total annual solar contribution (4%). The minimum roof angle is 10% for with-pitch installations.
Key operating considerations Solar cylinders differ from conventional cylinders in two fundamental ways. The first and most obvious is that much of the primary energy used to heat the water is provided free by the sun. The second difference is that input from the sun varies during the course of a day and from season to season. Annual variation often ranges from low levels of solar energy at times of greatest need to excessive levels at times of least need.
Not only does the level of solar energy vary during the day, it often varies widely from day to day. If the free solar energy component is to be maximised, the storage capacity of a solar cylinder needs to be optimised to accumulate residual energy from a previous good day to one for which the solar input may be insufficient.
With these principles in mind, the following operating recommendations should be followed to optimise the utilisation of free solar energy:
• The solar collectors should be suitably installed to achieve maximum solar energy input.
For maximum solar contribution:
• Correct orientation of the collectors relative to the location. • Correct inclination of the collectors. • No shade over the collectors. • Glass on the collectors should be kept clean. • The majority of the hot water should be used in the morning.
Solar collectors operate most efficiently when the inlet water is cold. Therefore the maximum solar contribution to the system will be achieved by starting each day with a tank of cold water, and letting the energy from the sun heat the water throughout the day. This is best achieved by ensuring that showering and the use of washing machines is performed early in the morning. This partially fills the tank with cold water, letting the sun work during the day to heat the whole tank, having only a small draw of water at night. This means that there will be only a small amount of supplementary electric heating required at night, and a tank full of hot water ready for use the next morning.
The action of auxiliary electric heating should be managed to permit the maximum possible solar contribution, with regard for patterns of hot water usage
Auxiliary heating for Beasley solar cylinders is provided by an incoloy sickle element that is controlled by an adjustable thermostat.
The element is located at the mid-point of the storage cylinder and is installed in the factory with the sickle curving downwards. This allows almost all of the water in the tank to be heated by the element. For instance a 3.6 kW element is capable of heating 330 litres of storage cylinder water from 25 °C to 60 °C in approximately 3.7 hours. This can be calculated using the following formula:
Beasley Hot water Solutions Split System Product Manual – issue 1 7
Beasley Hot water Solutions
Energy (kJ ) = Volume ( Litres ) x Change in Temperature ( Deg. C ) x Specific Heat ( kJ / kg Kelvin )
3600 (seconds in 1 Hour )
Also Time ( Hours ) = Energy ( kJ )
Element rating ( kW )
Calculating the above example
Energy = 330 x 35 x 4.18 = 13.41 kJ Hence Time 13.41 = 3.7 Hours
3600 3.6
The operation of the element is controlled by an adjustable thermostat. The thermostat can be set to cut off at any temperature between 50 °C and 70 °C. The thermostat will cut in at a temperature 8 degrees below the temperature at which it is set. The thermostat is preset in the factory to cut off at 65 °C (and it will therefore cut in at 57 °C).
• Do not let the element operate during daylight hours.
If the element is allowed to operate in daylight hours, it will simply heat the water from the ambient temperature up to 60 °C, (in approximately 4.5 hours if starting with a cold tank) and leave the solar collectors to raise the heat of the water to a temperature above 60 °C. Solar collectors operate with declining efficiency as higher water temperatures are reached, this method of operation fails to utilise the free solar energy which is available to heat the water to 60 °C and attempts to inefficiently transfer some solar energy into hot water at the higher water temperatures.
The solution to this problem is to have a time switch connected to the element that permits only night time operation, or to have the element connected to night time tariff electricity. Many electricity utilities have reduced tariff electricity available in off peak periods at night, allowing auxiliary heating power for the solar system to be purchased at a lower rate.
If the majority of hot water usage has been restricted to the morning, and the system has most of the day available to heat the water using solar power, then there will be little need for auxiliary heating overnight. On days of high solar gain, the water in the tank will attain a temperature in excess of 65 °C. A Beasley solar cylinder located on the roof will generally suffer a heat loss of only 2 °C to 3 °C overnight. If the water has been allowed to heat all day using solar power, even the use of some water in the evening will not draw sufficient cold water into the tank to reduce the temperature to the 50 °C at which the thermostat will cut in, and there will be sufficient hot water remaining for major usage the following morning.
Thermostat Temperature Setting
The thermostat has been set so that if the temperature of the water falls below 50°C, the water will always be reheated to a temperature of 60°C. This setting is based upon the requirements of Australian Standards for water in all forms of hot cylinders to be stored at a temperature of not less than 60°C. This is over the safety margin of approximately 55 °C which is thought to be sufficiently high to kill off any Legionella that might be present. The time required to heat the water in the tank from 50°C to 60°C using auxiliary power is approximately 1.1 hours. Each thermostat is subject to some variation in accuracy - if maximum solar contribution is sought, then the precise setting of the thermostat should be checked to ensure the thermostat cuts out at the minimum possible temperature.
Positioning of the Element
The element has been set at the factory with the sickle curving down to heat the maximum volume of water, heating and delivering close to the nominal volumetric capacity of the storage cylinder while operating as a purely electrical cylinder (if required). If operational experience on site shows that there is more than adequate supplies of hot water for the particular usage pattern, then the elements may be swivelled 90° so that the sickle is in the horizontal, rather than the vertical plane. In this configuration, the element can only heat the top half of the water in the tank, and the solar radiation has more scope to work on the cooler water in the bottom half of the tank. This will provide a more efficient solar contribution, but at the possible expense of reducing the amount of hot water that can be delivered in the morning following heating overnight by electricity.

Usage Patterns
• Hot water usage patterns should be managed to the greatest extent possible.
Maximum solar contribution will be achieved by using most of the hot water in the morning and providing a cold storage cylinder of water for the sun to heat during the day. This usage pattern may be more difficult to implement when there are a large number of people using hot water. However, if high solar efficiency is sought, efforts should be made to encourage the use of hot water early in the morning.
If the building is to be left unoccupied for a time, the electricity supply to the auxiliary power should be switched off. The system will continue to function and fill the cylinder with solar heated water, the temperature of this will be limited by the action of the temperature differential controller switching the pump off at 65°C. If there has been a period of low solar gain, the electricity should be switched on again prior to re-occupation to ensure that all the water has been heated to a useable temperature.
The average usage of hot water in a domestic household is normally taken to be 60 litres per person per day.
Load Calculations
Estimates of hot water requirement are at a stored water temperature of 60°C. This complies with Australian Standard AS3500.4 to prevent the occurrence of the bacterium Legionella pneumophila which could lead to a disease normally referred to as legionnaires’ disease. The hot water requirements for showers, hand washes, dish washing, laundry etc., are based on industry experience over the past fifty years.

Manufacturer Terminology
Terminology can be confusing. Solar storage cylinders in Australia are manufactured with nominal storage capacities of 160 litres, 250 litres and 315 litres. However, the actual ‘rated capacity’ of a storage cylinder differs from its nominal capacity, and differs between manufacturers. The capacity of a storage cylinder to deliver hot water differs from its nominal storage capacity because of:
• The location of the inlet and outlet pipes in the storage cylinder, and • The shape, size and location of the heating element.
The ‘rated delivery’ of a storage cylinder is the amount of water delivered at the nominal thermostat temperature when only electrical heating is used.
The ‘draw down capacity’ of a hot water system is defined as being the amount of water the system can deliver at a defined rate before the temperature of the water at the outlet drops 12 °C. Typically for the Beasley Solar Prestige 315 L storage cylinder, this is over 310 L (see Figure 4). During manufacture Beasley storage cylinders have the elements installed to maximise the delivered capacity.

Water Quality
Water quality cannot be defined by a single parameter as the suitability of water is defined by a numberof which are incorporated in a measure called the Saturation Index. If this index lies between -0.8 and +considered suitable for direct use in hot water systems. The limits on some individual parameters includSolids content being less than 600 mg/l and Total Hardness, expressed as Calcium Carbonate (CaCO3mg/l. Measurements for chlorides and pH also apply. It is recommended that where calcium hardnealkalinity of water supplies are in excess of 200 mg/l, the water should be treated by a softening procesto the Warranty section for specific details.

INSTALLATION INSTRUCTIONS
Preface These instructions cover the procedure for installing the Model 12S/12NS/12SB, floor mounted, mains pressure, electric water heaters. The installation must be made in accordance with these instructions, and also in conjunction with Australian Standard 3500.4 "Installation of Domestic Type Hot Water Supply Systems" together with any relevant local electrical and water supply regulations. Weights of the heaters (full) are 160L - 223 kg, 250L - 300 kg, 315L - 400 kg. The weight of each collector (full) is 38 kg. Water Heater Location Install the water heater as close as practical to the most frequently used hot water tap(s) and ensure an unobstructed access for maintenance. The valves of the water heater must be readily accessible for service. 300mm clearance alongside the heater is needed for removal of the P&T relief valve. The water heater should be mounted on well seasoned, evenly spread, hardwood slats with a thickness of at least 25mm. The CENTURION water heater carries an IPX4 rating; making it suitable for either indoor or outdoor installation. If the heater is mounted in a location where spillage could cause damage it shall be installed on a properly drained safe-tray.
Water Connections Cold Water For Beasley Centurion (which are provided with separate solar return connection as standard): Install the additional 15mm tee and 15mm nipple at the inlet (lowermost connection) to provide a connection for the solar cold flow. For other water heaters with no separate solar return connection it may be possible to install a solar five way connector. Seek advice from the cylinder manufacture re suitability. Refer to markings on the five way connector for connection details. Typically, attach the cold supply to the “COLD” connection. The connection to the pump is labelled “PUMP” and the solar return connection is labelled “COLLECTOR”.
Warning: the five way connector will not work from the base fitting of a Centurion or any other cylinder on which the 5 way connector cannot be installed with direct access to the stored water. This is because of the mixing which occurs in the tube before entering the cylinder.
Solar Return (Collectors To Tank) For Centurion: If present remove the 20NB plug from the solar return connection (200mm above the cold supply connection). Fit a 20 x 15NB reducing bush, a 15NB M&F elbow then a 15NB nipple ready for the solar return connection. NOTE! The temperature of the water at the outlet connection on the collectors may reach 150°C and therefore only use copper tubing between the collectors and the cylinder. Circulation Pump Mount the solar control unit in a vertical position using the screws supplied in the kit. Fit a tee to the cold inlet to the cylinder and connect this to the pump inlet port. Fit the restrictor to the outlet port of the pump and the solar non-return valve to the restrictor using a 15NB nipple.
The solar non-return valve protects the pump against steam flashing back from the collectors and also prevents back-syphoning of hot water from the cylinder to the collectors during periods of poor solar radiation.

Pressure & Temperature Relief Valve (PTR or TPR) If a boosted water heater is used then check the supplied relief valve is adequate for the applied loading. Add the total simultaneous electric input (the maximum element size for a non-simultaneous boosted unit or the TOTAL of the elements for a simultaneous unit) in kW to the total potential solar input at 0.9kW per collector.
Check the power rating on the PTR valve (typically 10.0 kW for a 15mm valve or 30.0 kW for a 20mm valve). The valve rating MUST EXCEED the total input. If it doesn’t, exchange the valve for a larger one that does.
Example 1:
12NS-250 with 4.8 kW elements wired non-simultaneously (typical in NSW and Victoria) with two collectors has an input of:
4.8 + 2 x 0.9 = 6.6 kW which is less than 10.0 kW, so the standard PTR valve is OK.
Example 2:
12SB-315 with 3.6 kW elements wired simultaneously (typical in South Australia) with three collectors has an input of:
2 x 3.6 + 3 x 0.9 = 9.9 Kw which is less than 10.0 kW, so use the standard PTR valve.
Collector Flow and Return Pipes 15mm copper tube is used for the cold flow and solar return in a system of up to 5 collectors. All pipe work connecting the cylinder to the collectors should be clad in PE foamed insulation such as indaflex.
Sensor Leads For systems with differential control, insert the hot sensor into the air bleed/hot sensor assembly, sealing in place with thermoplastic putty or silicon as shown in Fig. 6.
Figure 6 – Hot Sensor Sheath
N
Run the hot sensor lead down with the solar return line to the controller. Ensure the lead is not likely to be damaged. The standard leads supplied are 15metres long, longer leads are available. Plug into the controller.
Secure the cold sensor lead to the cold flow line just before it enters the pump, with PVC electrical tape or similar. Ensure the sensor is well insulated. Run the cold sensor lead to the controller. Ensure the lead is not likely to be damaged. Plug into the controller.
Relief Valve Drain Lines Connect independent copper tubes (15mm) to each relief valve drain outlet and run with a continual downward grade to a visible discharge point over drain or gully. Drain lines must not exceed 9 metres in length. Valves or other restrictions must not be placed in the relief valve drain outlet line. Note that some water will drip from the drain line during heating of the water.

Connect gas feed pipe as per AGA 102. Remove front cover of Rinnai heater and set dip switches as per figure 11. Replace front cover.
Filling Instructions
(i) Turn on the hot water tap at the sink. Open the stop cock in the cold water mains supply line.
(ii) Turn off the hot tap when non-aerated water flows. Check all connections for leakage and tighten if necessary.
Draining Instructions (i) The power supply to the water heater must be switched off and fuse(s) removed.
(ii) Close the cold water mains supply stop cock
(iii) Open a hot tap to relieve pressure
(iv) Disconnect the hot outlet tube from the P&T relief valve.
(v) Open up the drain cock and the inner cylinder will drain completely.
Routine Maintenance
(i) The Pressure and Temperature Relief Valve should be eased at least every six months to ensure the reliability of the valve. Open and close it gently. If the valve does not run, or does not seal again, replace the valve. It is not serviceable.
(ii) Replace the P&T valve at least every five years, more often on scaling water.
(iii) The "Centurion" water heater has no anode to replace. (iv) Draining and flushing the water heater on a 5 yearly basis, or more often if the water is particularly silty, may extend
the life of the heater and elements.
System Orientation and Frame Options Figure 13 illustrates various options that are available to enable the solar collectors to be installed at the correct angle on various types of roof, whilst also enabling the storage tank to be mounted horizontally. Careful consideration must be given to ensure that a shadow will not fall over the collectors during the day due to other sections of roofing. For special installation requirements, for example in cyclone areas where the standard cyclone frame may not be used, please consult your nearest BEASLEY representative.
NOTE : The method of mounting the collectors is a most important factor in the satisfactory operation of the system. Finishing the Installation Check and replace any tiles that may have been damaged during installation. Advise the customer of the recommended operating and maintenance procedures and complete the 'Warranty Certificate' at the end of this manual. Pre-Commissioning Checklist
a) Are all the bolts tight on the roof framework b) Are all solar collector straps fitted and correctly anchored to the roof structure c) Are all pipe connections fitted correctly and tightened. d) Are the solar collectors installed with the correct slope. e) Is the installation finished neatly with the roof made good, all tiles and flashings in place. f) Has the electrical installation been completed correctly and all connections tightened and conduit entries sealed
from the weather. Warning :- Ensure that the system is full of water before switching on the heating element

Commissioning the New System When the new hot water system is full, and no air is apparent at the hot water taps, the entire system should be checked for leaks. Pay particular attention to fittings in inaccessible positions, such as on the solar collectors and storage tank situated on the roof. If leaks are detected the system must be drained and the leaks repaired before the system is refilled. If this is necessary, cover the solar collectors to prevent them from excessively heating any water still in them. Check that the thermostat is set between 50 and 65 degrees centigrade, replace the cover correctly and switch on the electrical circuit breaker ( or install the fuse ). Check the operation of the P & T relief valve, and after a period of time, that the element in the storage tank is heating the water correctly. Warning: Water in collectors may exceed 90°C so extreme care should be exercised during the draining operation. In clear sunshine partially drained collectors can easily generate steam which will flow from a hot water outlet point. The new hot water system is now ready for use.

Beasley Hot water Solutions
SOLAR GAS SPLIT SYSTEM The Solar Gas split system comprises roof mounted solar collectors, a model 12S water storage tank and a Rinnai Infinity continuous gas heater. The tank/heater unit is located at ground level. A pump circulates the water through the solar collectors where it is heated by solar energy and stored in the tank. The pump is automatically regulated by a programmable electronic controller, only circulating the water when there is heat energy available from the sun.
When a hot tap is turned on, water at mains pressure passes from the tank through the continuous gas heater (which is plumbed in series), where it is boosted to a preset temperature (typically 60degC). If the temperature of the water is already at 60 degrees or above due to solar pre-heating, the gas burner will not come on.
Tank capacities available are 160 litre, 250 litre and 315 litre.
The Rinnai Infinity continuous gas heater is fastened to the front of the tank casing and is directly plumbed into the hot outlet of the tank. The gas heater can also be wall mounted alongside the tank, but plumbed into the system in the same way.
WARNING. Care should be taken when handling the tank/gas heater, as this unit is top heavy and likely to overbalance.

LOCATION AND ALIGNMENT OF SOLAR COLLECTORS
In the tropics the collectors may face in any direction. Elsewhere collectors must face the Equator +/- 35° in an area free of shadow between 9 am and 3 pm. AS3500.4 has a very useful "Midwinter Solar Altitude Sight". The angle of inclination should ideally match the angle of latitude of the site. eg for Adelaide, 34°. This is especially important in order to maximise winter collection. Due to thermal expansion as the collectors heat up, a maximum of six collectors only can be connected in parallel. Running flow and return connections to opposite corners of the collector array is recommended. It is normal to mount the solar collectors down close to the gutter. Roof construction must be checked to ensure that the roof timbers are capable of supporting the additional load. Refer to AS3500.4 Appendix H. Check for cracked or damaged tiles in the area of proposed installation. Replace any faulty tiles. If spare tiles are not available, swap damaged tiles with good ones from along the gutter line.

Marking a Tiled Roof with the Location of Collector Mounting Straps
Do this BEFORE hauling the collectors up onto the roof.
Obtain a heavy crayon or chalk to mark the tiles with the required location of the ends of the Collector mounting straps, and obtain a long straight edge (such as a piece of timber or tube). Lay the collectors together on a flat surface, with the straight edge along the bottom edge. Place all olives, nuts and nipples used for connecting the collectors together on the pipes and do up hand tight. Ensure that the pipes are fully entered into the fittings. Once this has been established, tighten the compression fittings which join the collectors together until the olives are sealed on the pipe. Mark the centres of the mounting strap holes which will be used, and the mid point of the collector bank, onto the straight edge. Note that it is normally the extreme mounting strap positions which are used together with intermediates as required. Undo the compression fittings, leaving the nuts and olives on the collectors.
Marking the Location for the Lower Collector Mounting Straps
Establish the row of tiles on which the bottom of the collector will sit and also the location the lower left mounting strap. For aesthetic reasons it is usually best to mount the collectors as close as practicable to the gutter. It is best if the strap locations are nominally half way down a tile. Mark the location of the bottom left mounting strap. Using the marked straight edge, and ensuring that it slopes up the roof about 8mm/collector, mark the location of the other mounting strap
Attachment of Collector Mounting Straps on a Tiled Roof Remove 2 or 3 tiles above each of the marked positions and nail collector mounting straps to the tile battens, so that the hole in the ends of the straps are at the marks on the roof, as shown in Figure 14. Pilot drilling the holes for the clouts is recommended. It is wise to wrap the strap around the batten for maximum strength. Replace the tiles.
Positioning of Collectors on a Tiled Roof
Carefully lift the collectors up onto the roof. If more than one collector is being installed connect the collectors together with their compression fittings after placing on the roof. If the roof is distorted it may be necessary to pack up the corners of the collector to achieve alignment. Attach the mounting straps to the collectors, using the screws supplied. A small amount of Silicone Sealant should be applied both to the screws and around the threaded holes prior to inserting the screws into the collector.
Installation of the Upper Collector Mounting Straps on a Tiled Roof
Once the collectors are in position, remove tiles from above the collectors and fit the upper mounting straps as per the lower ones. Replace the tiles.
Installation of Collectors on an Inclined Iron Roof Special care must be taken to check that the roof structure is capable of bearing the load imposed by the hot water solar system .(See AS3500.4) Determine the position of the roof purlins (usually by the line of nails). Drill through the purlins, apply some silicone sealant down the hole to ensure no water leakage is possible and secure with 5/16 galvanised coach screws. Mount the collectors on the roof. Join the collectors using the brass interconnecting unions supplied. Attach the mounting straps to the collectors, using the screws supplied. A small amount of Silicone Sealant should be applied both to the screws and around the threaded holes prior to inserting the screws into the collector. Adjust the position of the collectors to achieve the 8mm/collector rise as per Figure 10. The collectors will look slightly askew on the roof. If necessary drill through the support straps, and secure the collectors with 1/4 galvanised coach screws.

INSTALLATION INSTRUCTIONS FOR FLAT ROOF MOUNTING FRAME NOTE: This frame is not suitable for installation in cyclonic areas. For the correct frame for use in cyclone areas, contact your local Beasley distributor.
The kit contains:
• Truss assemblies.
• Rear diagonal brace.
• Solar collector support bars.
• Nuts and bolts.
• “Top-Hat” sections for installations parallel to roofing material ridges.
Bolts to connect the frame to the roof are not included because requirements differ between building authorities.
Assembly Instructions – See Figures 22 & 23
Each of the truss assemblies comes loosely bolted. Lay the medium sized member of one of the trusses on the roof, lift the long member, rotate the short member upwards to the vertical and bolt it to the long member. Tighten all the bolts. Repeat for the other trusses Position the truss assemblies on the roof as shown in the diagram, and secure the trusses together by bolting the rear diagonal brace to the marked holes on each of the rear members. If required, mount the Top-hat sections beneath the frame. Attach one solar collector support bar to the bottom hole in each of the trusses, as per the diagram, and semi-tighten the bolts to hold in position. (The second to bottom hole in the trusses is for use only with the SP201 collectors). Cradle the solar collectors within the bottom support bar, using the bar as a straight edge, and centralise the collectors on the bottom bar. Loosely fit all the inter connector assemblies and seals to the solar collector joins (Refer Collector Installation Instructions). Lay the top support bar on the solar collectors and loosely bolt to the trusses Using a spirit level, check that the solar collectors have the correct rise (as specified in Collector Installation Instructions), and when correct tighten all inter connector assemblies and all bolts on the frame assembly Secure the frame to the roof in accordance with local building authority regulations.

INSTALLATION OF CYCLONE MOUNTING FRAME FOR SPLIT SYSTEMS
Preface Before commencing the installation, check all components are included as shown in the kit list on page 30 of this manual. No components are supplied for mounting the frame to the roof. Location Choose the mounting location with direction in mind, that will allow the frame to be centrally located over three rafters and to also provide the top hat sections with suitable fixing battens as shown in these instructions. Locate the system towards the centre of the roof if possible. TO INSTALL THE SOLAR COLLECTORS “CLEAR OF THE ROOF” NOTE:- This method of installation must be used on tiled roofs. Lay the two top hat sections parallel on the roof, with their centres to suit the particular roof configuration. Attach the two C-section support bars to the top hat sections using 3/8" BSW nuts and bolts. SEE FIGURES 16 & 17 Square up the frames by equalising the diagonals and then tighten the bolts. Use the assembled frame as a template to mark the position of the mounting rods onto the roof tiles. The frames use one rod on the outside of each “C” section and one rod at the mid span of the top hat section.

Pre-drill the hardwood battens with a 12mm drill with hole positions to suit the particular frame. Three holes must be drilled in each batten for the 180L & 480L frames. Attach the hardwood battens to the roof trusses or rafters using a G.I strap and nails. Position tiles over the battens and mark the hole centres onto them. Remove tiles and carefully drill a suitable clearance hole through the tile at the marked points. Before replacing the tiles, attach the galvanised screwed rods to the hardwood battens, using nuts and washers to secure. Replace the tiles over the battens allowing the threaded rods to protrude through them. (NOTE the rod should be a maximum of 175mm above the roof support) Fit washers and the galvanised pipes over the threaded rods and seal around the tile with suitable silicon sealant. Fit a washer on each of the threaded rod supports. Place the frame over the mounting supports, aligning the bolts with the pre-drilled holes in the top hat sections, and secure with galvanised nuts and washers. Loosely fasten the frame to the supports, recheck the squareness of the frame by measuring it’s diagonals. When the two dimensions are within 5 mm tighten all the nuts and bolts on both the frame and the mounting supports.

On an Iron Clad Roof Lay the two top hat sections parallel on the roof, with their centres to suit the roof configuration. Attach the top C-section support bars to the top hat sections with 3/8 BSW nuts and bolts. Check the side rails centres are as per figure 16 or 17. Square up the frames by equalising the diagonals and tighten the bolts. Position the hardwood battens under each top hat section. Fasten the lower top hat section to the batten with a screw through its centre, using the slotted holes provided. Before this is tightened check the alignment of the frame for efficient thermosiphon angle, and screw in the remaining TEK screws for both the upper and lower top hat sections (Fig 19.)
Figure 19 – Top Hat Rail Fixing
Installation of Collectors Connect the bottom collector mounting bar to the C section using two of the 3/8" BSW nuts and bolts provided through the slots which are 65mm from the end of the C Section.. Remove the 3-off 6mm setscrews from both ends of the collectors. Place the two collectors on the frame, using the bottom collector mounting bar to support the collectors. Fit the compression unions to the centre collector joints. Note that it is very important to have the union olives fully seated on the pipes before the collector is installed. For an efficient thermosiphon operation the right hand side of the collectors need to be slightly higher than the left hand side. Set the bottom support bar to achieve this incline and tighten the nuts and bolts. Once the compression unions have been installed and tightened, position the collector bank centrally on the bottom support bar. Attach the top collector support bar to retain the top of the collector bank and fasten to the side rails using two 3/8" BSW bolts and nuts.

Locating the Frame
The Base Rail (Top Hat section) which supports the short legs must be located on the nose of the tiles. The legs at the high end of the frame must be located directly above a roof rafter.
Modifying the Frame to Suit the Roof Pitch. Position the upper Top Hat section on the tile nose. Remove the roof tiles from the position of the lower Top Hat section, lay it in position, and measure the vertical distance between them (dim “X” in Fig 23). Add 324 to this dimension and cut the plain end off the long extensions to make them this length.(eg Vertical dimension “X” is 200, cut the long legs 524 long.) Drill a Ø11.0 hole through the long extensions 20mm from the plain end to match the hole in the angle cleat.
NOTE: This frame is not suitable for installation in cyclonic areas. For further details, please contact your local Beasley distributor.
Assembling the Frame Assemble the left and right hand triangular frames as shown in Fig 15. Note that the installation instruction supplied
with the Flat Roof Kit shows the lower angle with its toes in but for this installation toes need to be out. Bolt the long extensions to the triangular frame which will be installed on the lower part of the roof. Bolt the short extension supports to the triangular frame which will be installed on the higher part of the roof. Attach the
cross braces and collector support rails. Bolt the angle cleats to the top hat sections and then loosely attach the frame to the cleats. Put the frame into position and secure the lower top hat section to each rafter that it crosses with coach screws. Hook the two cylinder mounting straps to the upper top hat section and nail them onto roof rafters under the tiles Tighten all frame nuts and bolts. Replace tiles and flash around the long legs.

INSTALLATION OF REVERSE-PITCH ROOF FRAME FOR SPLIT SYSTEMS
Preface: Before installation, check that all the components are included in the kit. NOTE: This frame is not suitable for installation in cyclonic areas. For further details, please contact your local Beasley distributor Locating the Frame The Base Rail(Top Hat section) which supports the end of the triangular frame must be located on the nose of the tiles. The legs at the high end of the frame must be located equally spaced across roof rafters.
Modifying the Frame to Suit the Roof Pitch Position the upper Top Hat section centrally across 3 rafters with the lower edge on a tile nose and hook the two cylinder straps onto it and nail them to the roof rafters. Ensure that the left hand end (looking up the roof) is approx. 12 mm higher than the right hand end. This slight slope is to promote correct thermosiphon action through the collectors. Remove the roof tiles from the position of the lower Top Hat section, lay it in position, with the "U" brackets in place, and measure the vertical distance between the holes in the two brackets (dim “X” in Fig 23). Mark this position on the two RHS sections, and drill Ø11 holes. Cut off the surplus RHS section 15mm down from the CL of these holes. Assembling the Frame Assemble the frame as shown in Figures 21 & 22. Note that the sloping angle iron has a toe in and the horizontal angle iron has a toe out. This allows the angle cleat to be bolted to the lower end of the frame with its toe in. Bolt the cross braces to the RHS support legs and bolt the lower collector support extrusion to the sloping angle iron using the holes nearest the end. Note that the braces may slope in the opposite direction to that shown in the diagram. During the frame assembly it is advantageous to loosely attach the upper collector extrusion also. Secure the lower top hat section with 8mm coach screws to each rafter that it crosses. Tighten all frame nuts and bolts. Replace tiles and flash around the legs. Mounting the Collectors Sit the collectors onto the lower support extrusion Connect the collectors together using the DN 20 compression fittings Slide the upper support extrusion down over the collector ends and install the mounting screws. Continue as per the collector installation Instructions.

ELECTRICAL WIRING CONNECTIONS
SINGLE ELEMENT HEATER It is recommended that all CENTURION water heaters (160, 250 and 315 litre) be connected to an independent, fused, 240V AC "off peak" power supply.
Figure 24 – Heater and Thermostat Wiring
Beasley Water Systems Product Manual
Beasley Hot water Solutions Product Manual 35
BOOSTER ELEMENT HEATER
Boosted heaters are wired for either "simultaneous" or "non-simultaneous" operation The standard boosted CENTURION for domestic use has a 40 litre boost volume. 315 litre and 250 litre units with a 125 litre and 80 litre boost volume respectively are available as an option.
WIRING INSTRUCTIONS – SIMULTANEOUS & NON-SIMULTANEOUS OPERATION
Figure 25 – Wiring Label Detail WARNING
Electrical work may only be done by a licenced tradesman and must be in accordance with AS3000 SAA Wiring Rules and local regulations. The following instruction is issued as a guide only.
BACKGROUND
Boosted water heaters are recommended when there is an occasional heavy demand for hot water or when running out of hot water is unacceptable. They are also recommended for use with pumped solar systems. With a 3.0kW element the standard 40 litre boost volume comes up to temperature in about 45 minutes. Boosted water heaters are usually wired in one of two ways - simultaneous or non-simultaneous. Selection of the operation depends on local wiring rules, available power and customer requirements. Non-simultaneous operation is usually preferred when: local authorities allow connection of the upper (boost) element to off-peak tariff bypassing the time clock. off-peak power is unavailable, particularly where the supply cannot power both elements simultaneously, total heating input exceeding 7.3kW (including solar) is desired or required and the standard 7.3kW pressure and temperature relief valve is to be retained.
Beasley Water Systems Product Manual
Beasley Hot water Solutions Product Manual 36
Simultaneous operation is preferred when: local regulations require a continuous booster to be connected to mains tariff, it is occasionally desired to run the booster only (eg as a backup to a solar or slow combustion system), particularly through an accessible switch or a current held relay.
CONNECTION FOR SIMULTANEOUS OPERATION
Figure 26 shows the recommended connection for simultaneous operation. The on/off switch or current held relay are recommended to make the most of off-peak or solar power. In both instances a readily visible lamp is recommended. If the booster is left running continuously the occupier should occasionally ensure the off-peak element is operating by checking for power use at the off-peak tariff meter. The current held relay provides power to the boost element until the thermostat opens, causing the contactor to release. Separate power supplies (including neutral) with their own fuses are required for each element. Both power supplies may be run through the lower electrical entry, running the booster supply up through the conduit.
Figure 26 - Typical Connection for Simultaneous Operation
CONNECTION FOR NON-SIMULTANEOUS OPERATION Figure 27 shows the recommended connection for non-simultaneous operation. All wiring passes through the lower entry. If local supply authorities do not allow bypassing of the time clock as shown then the booster should be connected to mains tariff. A common neutral is used. If the lower element fails to operate then the upper element will do all the heating. This is expensive if the upper element is at mains tariff. The occupier should occasionally ensure the off-peak element is operating by checking for power use at the off-peak tariff meter. If the upper element fails to operate, it will prevent the lower element from operating.

CONVERSION FROM SIMULTANEOUS TO NON-SIMULTANEOUS OPERATION
To convert a water heater wired for simultaneous operation to one suited for non-simultaneous operation: (i) Obtain a Beasley Non-Simultaneous Kit Electrical, Part No 332-03-701 for Centurion 250 litre or 332-03-703 for Centurion 315 litre which includes the cables, "Non-Simultaneous" sticker, three way terminal block and this instruction. Alternatively obtain suitable lengths of 2.5mm2 105 C flexible cable. (ii) Check the upper thermostat. A Robertshaw W2M2 is required and may be installed. If not, obtain one and install. (iii) Check whether there is the conduit running from the upper to lower electrical entry. If not, the wiring will have to be run externally: install suitable conduit, connections and flexible cable (the cable in the kit will not be long enough).
(iv Replace the two way terminal block at the lower element with the three way. Rewire as per Fig 27, running the
wires through the conduit.
(v) Apply the "Non-Simultaneous" sticker to the upper electrical door or adjacent to it, or clearly and indelibly write
THIS UNIT WIRED FOR NON SIMULTANEOUS
OPERATION OF HEATING UNITS
adjacent to the upper electrical door.
(vi) Connect as per above.
Beasley Water Systems Product Manual
Beasley Hot water Solutions Product Manual 38
CONVERSION FROM NON-SIMULTANEOUS TO SIMULTANEOUS OPERATION
To convert a water heater wired for non-simultaneous operation to one suited for simultaneous operation:
(i) Remove the wiring loom running from top to bottom. (ii) Install a two way terminal block at the upper electrical entry. (iii) Rewire and connect as per Fig 26. (iv) Remove the "Non-simultaneous" wording from the water heater.
THERMOSTAT TEMPERATURE SETTING
It is recommended the top thermostat settings is 10°C below that of the bottom. The bottom setting should be between 60 and 70°C.
Beware : The booster can be connected to continuous mains tariff supply which cannot be manually controlled when wired non-simultaneously. If the booster fails to operate (e.g. element failure) it will prevent the main element operating. In such an installation regularly check the "off-peak" element is working by checking for power use at the off-peak tariff meter. TURNING ON POWER
Check thermostat settings. AS1056.2 recommends thermostats are set between 60°C and 85°C for stainless steel water heaters and the booster thermostat be set 10°C below the main thermostat setting. Thermostats MUST NOT be set below 60°C due to potential Legionella and other microbial problems.
IMPORTANT Always check that the heater is completely full of water BEFORE turning on power supply. Failure to follow this procedure will render the guarantee VOID. Table 27 - Standard Booster Element Current Ratings

MAINTENANCE
Pressure and Temperature Relief Valve.
At 6 monthly intervals the P&T relief valve and Tempering valve should be checked and at 12 monthly intervals the whole system should be checked for general condition with specific emphasis on the following details.
Gently turn knob to check that water discharges through the drain and that the valve then reseals after the knob has been released. Take care that you are not in the path of the discharging water because it will be very hot. It is recommended that the PTR valve be replaced at intervals not exceeding 5 years.
Tempering Valve Confirm that the temperature of the water issuing from the hot taps is below the safety setting.
Pipe Joints. Ensure that there are no leaks from any of the pipe joints or collector connectors.
Collector Glass. Confirm that all the collector glass is unbroken and clean off any accumulated dirt. This will ensure that the collectors continue to operate at their maximum efficiency. Check the condition of the seal around the glass. Electrical. ENSURE THAT THE POWER SUPPLY IS ISOLATED.
Remove the electrical door from the cylinder end cap and check for any signs of arcing or water seepage. Installation Site Confirm that no changes have occurred in the vicinity of the system to cause shading of the collectors.
TROUBLE SHOOTING
General This section should be used as a guide to assist in quick location and correction of system faults and to ensure Beasley systems retain their position of high performance, quality and service.
Insufficient Hot Water (Solar) This can often be the result of the owner's reluctance to turn on the booster during periods of low solar radiation or high hot water usage. It is essential to establish the facts regarding usage patterns before any investigative work is conducted. Owners may not be aware of issues that can lead to perceived system inefficiency under solar only input conditions. The situations for consideration are: • Use of hot water above the system’s capacity. • High hot water usage at night. • Current weather conditions. • Household plumbing condition. • The owner’s understanding of booster usage. • The owner’s expectations of system performance. Having determined that these conditions are not responsible for the poor performance, the following check list may be used to identify the cause.
Trouble Shooting Check List • Orientation of solar hot water system and the effect of any shading. • Airlock in collector:
♦ Raise top right hand corner on system. ♦ Ensure that tank connections are higher than the collector connections.
• Slow leak from system or household pipes: ♦ Check water meter for movement. ♦ Pressure test pipes in the house.
• Blockage in connecting pipes. • Collector blocked with sediment.
Beasley Water Systems Product Manual
Beasley Hot water Solutions Product Manual 40
More Detailed Investigation • If the above check list items do not reveal any faults a draw-off test may be performed to demonstrate that the system is
performing correctly. (See draw off procedure below). • Should the solar hot water system be shown to be performing correctly it is possible that the household consumption is
greater than expected. To demonstrate this to the owner a water meter should be placed on the cold supply to the solar hot water system and daily recordings made for one month to establish average usage requirements.
• Water restriction devices may need to be considered if high usage is the reason for perceived poor performance. Fitting restrictors to shower heads and using cold clothes washing methods are the most successful ways to reduce hot water usage without affecting the owners comfort levels.
Draw Off Test Procedure (Solar Boosting) Before 9 AM draw off all the hot water from the storage tank, turn off cold water and booster supplies to solar hot water system. If the day has been clear, return to the system after 4 PM and turn the cold water supply on noting the supply water meter reading before drawing off the entire tank contents into the laundry trough. The water should be drawn one trough at a time with a record made of the temperature and water meter reading after each trough load. The first temperature measured should be approximately twice the daily maximum temperature and at least 75% of the tank volume is drawn before the temperature falls by 12°C from the starting temperature.
Insufficient Hot Water (Auxiliary Boosting) • Power supply or booster switch off. • Blown fuse. • Circuit breaker tripped. • Thermostat failure. ♦ Remove the thermostat and replace with new EWT1L2S thermostat. This thermostat has no “RESET” button. • Thermostat setting set too low. • Thermostat faulty (will not switch on). • Electric element faulty. ♦ Check element circuit continuity. • For OFF PEAK supply systems the electric sickle element should be fitted in the downward position if this is not the case
the element must be rotated until it is in the sickle down position to maximise the boosting capacity. Also have the time clock checked to ensure the auxiliary boost is being activated at the correct time.
• If all of the above check list items do not reveal the fault, a draw-off test may be performed to demonstrate that the system is performing correctly. (See draw off procedure below).
• When connected to an off-peak electricity supply, the quantity of hot water that is used must be less than the storage volume or the system will run out of hot water. Methods of hot water usage reduction need to be considered to overcome this problem or arrange to have a day rate change-over switch fitted to the installation for use during high usage, low solar radiation periods.
Draw Off Test Procedure (Auxiliary Boosting) Turn off cold water supply, allow tank to boost for a minimum of 5 hours on electric (ie. one thermostat cycle). Turn off the booster supply. Note the supply water meter reading before drawing off the entire tank contents into the laundry trough. The water should be drawn one trough at a time with a record made of the temperature and water meter reading after each trough load. The first temperature measured should be approximately 60oC and at least 60% of the tank volume is drawn before the temperature falls by 12°C from the starting temperature.
Auxiliary Booster Water Volume The standard electric auxiliary cylinders will heat the top 2/3 of the storage tank so that there is sufficient hot water to meet demands without seriously affecting the solar energy collection ability. Consequently the night stabilisation effect will be more pronounced when the only source of input energy is the electric or gas booster. This is because the tank bottom 1/3 is filled with cold water that can only be heated by solar energy.
Off-Peak Electricity Supply Most OFF PEAK supplies are available only during the night (no daytime boost) therefore the tank can be without any boost energy input from 7 am to 9 pm (ie. 14 hours). During periods of low solar radiation a significant run-down will occur after the early morning hot water usage. It is also advisable to install the electric element sickle down to increase the boosted volume in off-peak installations.
Beasley Water Systems Product Manual
Beasley Hot water Solutions Product Manual 41
Over-Night Temperature Stabilisation Over-night there is a reduction in the tank hot water outlet temperature caused by heat dissipation into the cooler water stored lower in the tank near the inlet position. The magnitude of this effect is proportional to the amount of water drawn over night (the more hot water used the greater the temperature drop). The outlet heat energy is not lost from the system but is stored in the cooler water lower in the tank. On some occasions it may be necessary to use the electric booster to heat the water in the top of the tank to a useable morning temperature. If hot water is not used from a 330 litre storage tank during the night the heat loss (temperature drop) under average conditions is approximately 5oC ( with the tank storage temperature at 70oC). As an example, if 60 litres of hot water is used during the night the morning tank temperature will be 61.5oC or a reduction of 8.5oC (5oC heat loss and 3.5oC of temperature stabilisation). If 160 litres of hot water were used during the night the morning tank temperature will be 50oC or a reduction of 20oC (5oC heat loss plus 15oC temperature stabilisation)
Direct Heat Loss Close coupled thermosiphon solar cylinders have the tank positioned above the collectors and therefore do not circulate water between the collectors and tank at night. Since water in the storage cylinder is warmer than that in the collectors, and as hot water always rises, the hot water will remain in the storage tank. As a result there is no night recirculation of hot water from tank to collectors.
Water Hammer If water hammer does exist the following points should be checked: • All pipes must be solidly clipped down. • Check tap washers at laundry, kitchen and basin taps, rubber washers can help reduce water hammer. ‘Flip top” style mixer taps and washing machine solenoid valves are primary causes of water hammer. This is due to the severe nature of the valve mechanism which open and close very rapidly. These are most effectively remedied using a water hammer arrester valve.
Water Discharge from the Cold Relief Valve The Cold Relief Valve is designed to release water from the system should the pressure rise above 700 kPa. Water discharge from the cold relief valve is normal when the water is being heated. A volume between 5 and 30 litres a day is quite common. If the discharge is greater than this volume the valve operation should be checked as follows: • Lift the valve hand lever to open and reseat the valve. • Inspect the valve seat for pitting or calcium build up. • Check mains pressure and fit a pressure limiting valve if excessive • Check that pressure is not feeding back from another device connected to the hot reticulation circuit. Particular attention should be given to dishwashers, washing machines and single lever taps. • Replace the valve only if discharge continues and the pressure is below the specification settings.
Water Discharge from the Pressure & Temperature Relief (PTR) Valve If a cold relief valve is fitted, water should not discharge automatically from the Pressure & Temperature Relief valve unless either the hot water temperature is at 93°C or the pressure is greater than 850 kPa. If water is being discharged from the valve the following checks should be made: • Lift the valve hand lever to open and reseat the valve. • Confirm the thermostat operation and replace thermostat if faulty • Inspect the valve seat for pitting or calcium build up. • Check the tank water temperature. • Replace the valve only if discharge continues and the pressure and temperature are below the specification settings. NB. If no cold relief valve is fitted then the Pressure & Temperature Relief valve will drip during every heating cycle, either solar or electrical boost.
Beasley Water Systems Product Manual
Beasley Hot water Solutions Product Manual 42
Insufficient Pressure The Pressure Control Valve of the Combination Inlet Valve is designed to limit the maximum supply water pressure to 450 kPa at a flow rate of up 15 litres per minute. If the pressure at the solar hot water system is less than 450 kPa and the flow rate is less than 15 litres per minute the following checks should be made: • Combination Inlet Valve water strainer blocked or restricted. • Pressure limiting Control Valve restricted with mineral deposits. • Supply pipe work to unit or hot outlet line pinched, blocked or under sized. • Mains supply pressure below 450 kPa, this will require installation modification by the user or supply authority. • Pressure Control Valve flow insufficient for the user’s requirements. This may be addressed by installing a larger valve or by fitting two limiting valves in parallel.
Thermostat Safety Cut-Out Activated The thermostat safety cut out is designed to disconnect the booster device from the supply if the temperature of the potable water rises above 87°C when the booster is operating. The potable water temperature can, however, regularly reach in excess of 87°C from solar collection when low usage rates are experienced, under these conditions the safety device will automatically reset when the temperature falls to below 72°C. If the high temperature is the result of booster operation the safety device will trip and can not be reset. When this occurs the thermostat is not repairable and must be replaced with the EWT1L2S thermostat.
General Condition Report If requested a general condition inspection can be conducted by your plumber which should cover the following items: • Collector condition, leaking unions, broken glass, damaged water seals etc. • Dirty glass, reducing efficiency. • Tank cover water tightness, check cover, tank ends, pierced skins etc. • Check auxiliary power connections • Inspect booster and safety devices. • Check shading of collectors. • Check relief and drain lines from Pressure & Temperature Relief Valve or Combination Inlet Valves.
