Basic Principals of Operation Your high rate sand filter is designed to operate for years with a minimum of maintenance and when installed, operated and maintained in accordance with these instructions.

Filtration - How Your Filter Works The basic principals of filter operation are as follows: Dirty water enters the filter tank by being pumped under pressure through the influent pipe and is distributed across the top of the inner tank chamber through diffusers. The water is then forced downward through the media filter bed. Dirt and debris is collected in the media bed allowing clean water to pass through. The clean water then passes through the collection laterals and exits the filter through the effluent piping and is returned to the pool. The pressure in the filter will increase and the flow of water through the filter will diminish as dirt accumulates in the filter. Eventually, the filter will become so obstructed with dirt that it will become necessary to backwash the filter. Please note that a filter removes suspended matter but it does not sanitize the pool. The pool water must be sanitized and the water must be chemically balanced for sparkling clear water. Your filtration system should be designed to meet your local health codes. Pool chemistry is a specialized area and you should consult your local pool service specialist for specific details.

Backwash The basic principal of filter backwash is to reverse the flow of water through the filter removing solids and waste trapped in the filter bed. For this principal to work properly a flow of 15-20 GPM per square foot of filter area should pass through the filter in the reverse direction. This will help to fluidize the media bed, loosening any solids trapped or compacted in the bed and then lifting the solids and transporting them out of the filter to waste. Usually a two to five minute backwash flow is all that is necessary to clean the filter. It is absolutely necessary to have a large enough waste line that will accommodate the backwash flow rate of the filter. In dual tank systems the high flow rate required for backwash is achieved by taking the normal flow through two filters in parallel and passing it through the filters in series. Flow is forward through the first vessel, filtering the water and backward through the second vessel, back washing the filter. This results in a backwash flow rate that can be twice as large as the normal flow rate. Given appropriately sized pumps, Stark filter face piping is designed to insure the flow necessary for adequate back washing.


Installation And Assembly Filters should never be tested or subjected to air or gas under pressure. All gases are compressible and under pressure create a danger. Severe bodily injury or property damage could occur if the filter is subjected to air or gas pressure. [All units are hydrostatically tested at the factory to 75 psi.] Locating the Filter The filter should be mounted on a level concrete slab. Position the filter so that the instructions, warnings and the pressure gauges are visible to the operator. It should be positioned so that the piping connections, manway, control valve and drain are convenient and accessible for servicing and winterizing.

Filter Installation 1) Prior to receipt of the filter, be sure to provide a permanent slab on which

to mount the filter. Preferably the slab should consist of concrete poured in a form. Alternately, the filter can be mounted on a platform constructed of concrete block or brick. DO NOT use media to level the filter or for pump mounting as it will wash away.

2) Upon receipt of filter check filter pallet and auxiliary cartons for any

evidence of damage due to rough handling in shipment. If the filter or any filter components are damaged, notify freight carrier immediately.

3) Carefully remove the accessory package and the filter tank from the cartons or wrappings. 4) Refer to appropriate specification sheet for the correct locations for the anchor bolts.

a. Ensure adequate space and lighting is provided for routine maintenance access. Minimum space requirements may be found on the filter data plate.

b. Position filter so that the port locations and manway are in the desired final position.

5) Once the anchor boltholes are located and drilled, place the filter tank on the slab, level the vessel(s) and bolt in place. Anchor bolt requirements can be found in appendices, Shipping and Installation Requirements.


Face Piping Installation Plastic piping systems should be ENGINEERED, INSTALLED, and OPERATED in accordance with ESTABLISHED DESIGN AND ENGINEERING STANDARDS AND PROCEDURES for plastic piping systems. Suitability for the intended service application should be determined prior to installation. IMPORTANT – WATER HAMMER – Paragon recommends that all plastic piping systems be designed and constructed to AVOID EXCESSIVE WATER HAMMER. Water hammer can cause damage and failure to pipes, valves, and fittings within the piping system. All pipes should be secured with adequate bracing and hangers to prevent damage to system from weight and vibrations. 1. Each filter system has custom face piping and the accompanying

submittal drawing should be consulted when assembling the face piping. 2. For systems that do not come pre-glued by factory the face piping is all

precut at the factory and needs to be glued on site to the fittings. This allows the installer some flexibility on the auxiliary piping configuration during the final assembly. Some pieces have been left slightly longer than necessary to allow field trimming.

SOLVENT WELD CONNECTIONS – Use a quality grade of primer and solvent cement formulated for the type of connection, with the CORRECT SIZE APPLICATOR. Read and follow all of the solvent cement MANUFACTURER’S APPLICATION INSTRUCTIONS. THREADED CONNECTIONS – Use a quality grade of Teflon tape recommended by the manufacturer for use with plastic. DO NOT USE OIL BASE PIPE JOINT COMPOUND OR TEFLON PASTE – they may contain substances that could cause STRESS CRACKING to plastics. A one to one and one half turn beyond hand tight is generally all that is required to make a sound plastic threaded connection. Unnecessary OVERTIGHTENING will cause DAMAGE TO BOTH PIPE AND FITTING. 3. Flange Make up – once a flange is joined to pipe, the method of joining

two flanges is as follows:

a. Piping runs joined to the flanges must be installed in a straight-line (flanges must be parallel) to avoid stress at the flange due to misalignment. Piping must also be secured to prevent lateral movement that can create stress and damage the flange.

b. Align the boltholes of the mating flanges by rotating the ring into

position.

c. Make sure the faces of the mating surfaces are not separated by excessive distance prior to bolting down the flanges.

d. Make sure to install a gasket between the flanges. The typical gasket is 1/8” thick neoprene.

e. Stark plastic flange bolts are designed for 25 ft/lbs torque working pressure. If more torque is necessary, substitute stainless steel bolts. Tighten the bolts on the plastic flanges by pulling down the nuts diametrically opposite each other using a torque wrench. Tighten bolts according to the sequence shown in the diagram. Completed tightening should be accomplished in stages and the final torque values followed according to the size of the flange. Uniform pressure across the flange will eliminate leaky gaskets.

Valve Installation 1. Per the submittal drawing the valves provided should be bolted in place to the face piping. Ensure valve orientation and flow direction (shown by an arrow on the valve) is correct for your application. In standard applications, the arrow on the 3-way valves should always point towards the tank. 2. The Stark valve is a simple design with few moving parts to wear out that can be modulated using hydraulic pressure from a simple city water line providing 30-40 psi. 3. To control the valves, (see appropriate schematic in Section VI, C either automatic or semi-automatic) a domestic water line should be run through the pressure regulator/reducer and an in-line check valve to the center port on the multi-port valve, all of which are provided, on the standard Stark filtration system. 4. DO NOT put the in-line check valve between the multi-port valve and filter

valve(s). The filter valve(s) are double acting and water has to be exhausted through the multi-port valve.

5. Connect the multi-port valve to the filter valve(s) by 3/8”OD plastic tubing.

See accompanying schematic for the correct configuration for your application.


6. Connect a 3/8” OD plastic tubing from the waste port of the multi-port

valve to an unpressurized waste line. DO NOT connect it to the filter backwash waste line.

7. It is highly recommended that a ½” PVC ball valve be installed on the

manual air relief located on the top portion of the tank. This is added to assist in relieving air from the tank while filling with water.

Automatic Controller When installing and using the Stark Automatic Controller, please use the separate manual that is included with the controller. The automatic controller is powered by a 24-volt ac source that is not provided with the unit. The unit comes preprogrammed from the factory with an erasable read only memory chip. If you need your unit to perform special functions please contact the factory as special requests can be accommodated with a replacement chip that allows correction in the field. Once system piping and proper valve installation is complete. Including hydraulic lines for valve activation. Hydro test system*. This must be done prior to adding media, start pump, allow system to fill with water to (bleed out all air). Run system for several minutes while doing this inspect for leaks and any unnecessary vibrations that can be reduced by additional support. At this time you will be checking that the pump is providing the flow and pressures in the desired system. Once this is done and installer is satisfied the previous criteria has been met, you may proceed in media installation. Failure to do this may result in damaged parts within the system, which may result in the warranty being voided.

Media Installation 1. Remove the manway cover from the tank. 2. Inspect the diverters on the top influent pipe the laterals on the bottom

effluent pipe. The laterals and diverters are threaded and screw into the manifold. Check each one to make sure they are secure and properly set in the piping. Check to ensure that all the laterals are properly installed in the tank with the slots facing downward and the lettering on the laterals upward stating “THIS SIDE UP”. If a diverter or lateral is removed take care when reinstalling to remove any foreign matter or media from the threads. Take care not to cross-thread when attaching items to the manifold.



3. Remove any packing material or loose foreign objects that might be found

inside the vessel. 4. Check to make sure the automatic air relief system is properly installed.

3/8” Flex tubing connects to the lower manifold in A, B or C style vessels or found on effluent manifold near top of tank in ‘S’ series vessels. The upper end of the tube has a screen cover on it and passes through one of the diverters.

5. Fill the vessel half full with water to help protect the lower laterals as the

media is installed in the unit. 6. Consult appropriate specification sheet found in appendices for Media Requirements (for the proper type and quantity of media required). 7. Carefully add gravel to the vessel by hand until the laterals below the

manway are covered. 8. Add the remainder of the required gravel. The gravel should then be

evenly spread out or raked so that it is level with the top of all the laterals. 9. Once the gravel bed is properly installed the media bed should be installed on top of the gravel. The media should be evenly spread out as it is installed and raked level. 10. At each 6 inch level above the gravel line, reinstall the manway and

backwash the filter. Backwash until water runs clear or for no less than 5 minutes at the flowrate specified on the label.

11. Ensure automatic air relief system is still in place and reinstall the manway

lid. Check that the manway o-ring is properly installed and the mating surface area on the tank are clean and free of any dirt or residue that might effect sealing.

Initial Start Up Procedure and Operation Read the following instructions carefully before trying to operate the filter. Prior to the actual start up it is recommended that the operator go through several dry runs to familiarize themselves with the operation of their particular system. Once familiar with the operations, the actual start up procedure can begin. For the initial start up semi-automatic and automatic systems should be started in the manual mode. 1. Turn on the city water supply going to the multiport valve. The multiport valve should be in the home position.


2. Check to ensure that the pressure regulator is set between 35-40 psi as read on the multiport pressure gauge. 3. Rotate the multiport valve to position 1. This will allow the back washing

of the first filter. It is recommended to initially backwash all the filters in the system when new media is installed in the tank(s) prior to returning the filtered water to the pool. The reason for this is to eliminate any fines that might be in the media.

4. Upon placing the multiport on position 1, the pressure to the multiport will decrease as the 3-way valve is being actuated. Wait until the pressure gauge returns to the pressure it was set at. 5. Make sure the water supply to the pump is available and any isolation valves going to the pump or filter are open. 6. Turn on the pump and allow it to backwash for at least five minutes. 7. Monitor the backwash line during the initial backwash procedure. During the initial few minutes you should be able to feel small grit in the backwash flow with your fingers.

a. If large sand particles or excessive media is being discharged restrict the backwash flow until no more media is being discharged.

b. If you do not find any small grit increase the backwash flow until you feel some small particles in the discharge.

8. Upon completion of the backwash shut off the feed pump. 9. Rotate the multiport valve to actuate the next filter in the system to backwash 10. Wait as the valve is actuated and the pressure in the multiport valve returns to its standard setting. 11. Turn on the pump and follow the steps outlined above for the backwash of this filter. 12. Continue the initial backwash procedure until each tank in the system has been back washed. 13. Once all the filters have been back washed shut off the feed pump and return the multiport to the home position. 14. The system is now ready to begin to filter the pool water. 15. Make sure all the proper valves to the pool and the pump are open. 16. Turn on the pump and begin the filtration process. Once the system

achieves a steady state note the influent and effluent system pressure.


17. The differential between these values represents the pressure drop

through your system when it is clean. Any time the pressure differential increases from this value by 10 PSI or more the system is in need of a backwash.

Maintenance and Service If problems should occur with the operation of your filter system, refer to the troubleshooting section of this manual to identify the cause of your problem before attempting to service the filter system. Before performing any maintenance or service on your filter shut off the electrical power and isolate the filter system with valves from the water supply and return.

Filter Care

1. Filter and Media

1. Turn off the electrical power to the filter system and close all suction and discharge piping valves.

2. For draining a vessel remove cap of Media Dump Assembly, if Media

Dump Assembly is not available on your tank model, loosen flange bolts on effluent piping manifold flange.

3. Open the manual air relief valve on the top of the tank to help speed the

drainage process.

4. Loosen the two bolts holding the yokes for the manway. One yoke will have to be removed from the cover.

5. Twist the remaining yoke to the side. Holding onto the manway turn the

manway sideways into the tank and pull it out of the tank.

6. Inspect the interior of the filter above the media bed for any signs of damage.

7. Inspect the media bed

a. Media bed should be flat. Channeling or media migration indicates a problem exists

b. Inspect the media for signs of contamination. c. Dig down several inches into the media. The media should be

loose with no signs of contamination. If the media is contaminated it should be replaced.


After observing the media the manhole cover can be reinstalled on the tank. Make sure the O-ring is in place. The sealing area must be free of any dirt or particles that could prevent sealing.

8. Once the manway is properly positioned turn the yoke to hold it in place and reattach the second yoke. Both bolts should then be tightened uniformly to reseal the vessel.

NOTE: After system is pressurized manway yokes may appear loose, finger tighten bolts only – DO NOT OVERTIGHTEN BOLTS.

2. Valves Should you have a problem with one of the diaphragm valves or the multiport valve, it is recommended that the valve be removed from the system. Please refer to the following instructions:

1. Shut off the electrical power and isolate the filter system from the water supply and return.

2. Turn off the city water supply to the multi-port valve.

3. Disconnect the hydraulic tubing from the valve.

4. Remove valve from system.

Diaphragm (3-way and priority) These units should only be disassembled and inspected if they are not functioning properly. The diaphragm valve has been specially designed for this service and should perform trouble free for many years.

1. The valve cover can be removed by loosening the bolts that attach the cover to the valve body. This cover needs to be uniformly tightened to prevent leaks and it should be removed by loosening the bolts diametrically opposed to each other. Loosening all the bolts on the cover at the same time.

2. Once the cover is removed the diaphragm and internal parts can be

inspected for any signs of damage. Consult the valve diagram in the back of this manual to determine the part numbers of any pieces that require replacement. Complete rebuild kits or individual parts are available from the factory as required.

3. Upon inspection the valve should be reassembled.


Multi-port To access this unit remove the six screws holding the housing in place. The internals of the unit as shown in drawing AI-MV250 can then be accessed. Observe the inside of the unit and repair and replace parts as necessary. Parts on the drawing listed with an (*) come standard in the basic repair kit. Upon inspection and replacement of worn or damaged parts the lip seals, cup seal and o-ring should be lubricated and the unit reassembled.

3. Sight Glass The sight glass is screwed into the backwash line of the system. It should be installed so that the deflector in the middle of the threaded connection is perpendicular to the water flow. To ensure proper orientation, make note of the position of the STARK lettering in relation to the deflector prior to installing the sight glass unit. Use the lettering to properly position the diverter. When correctly positioned, the diverter will force water through the sight glass during backwash.

1. To clean the sight glass, remove the four screws that hold the cap and glass in place.

2. Carefully remove the cover and glass tube.

3. Clean the glass with mild soap and water. Use caution as the glass

tube may have sharp edges.

4. Make sure that no contaminates are hung up or stuck on the deflector plate restricting flow through the pipe and sight glass.

5. Once the glass is clean, lubricate the gaskets on both ends of the sight

glass.

6. Take the sight glass and cover and reinstall it to the threaded fitting with the four screws. The screws should be uniformly tightened.


Cleaning Frequency During initial start up, your filtration system should be back washed. Back wash the system every 48 hours until you are satisfied that all contaminates or residue from construction has been removed from the piping and the filter bed. The filter(s) can be cleaned using several different parameters. The most common method is to backwash the filter(s) when the differential between the influent and effluent pressure significantly increases over the pressure drop through the system when it is clean. Any time the pressure differential increases from the clean differential by 10 PSI or more the system is in need of a backwash. Other methods of determining the backwash frequency can be as follows:

1. If a flow meter is available, backwash when the flow rate through the system diminishes by 30% indicating a loss of pumping efficiency.

2. The system can be backwashed based on predetermined run time cycles.

Filter Backwash Procedure (For semi automatic controller, for automatic controller refer to “Automatic Controller Owners Manual, see forced backwash section)

1. Turn off the filter pump.

2. Rotate the multi port valve to position 1. This will allow the backwashing of the first filter.

3. Upon placing the multi-port in position 1, the pressure to the multi-port will

decrease as the 3-way valve is being actuated. Wait until the pressure gauge returns to its standard setting.

4. Make sure the water supply to the pump is available and any isolation

valves going to the pump or filter are open.

5. Turn on the pump and allow it to backwash for three to five minutes.


6. Upon completion of the backwash shut off the feed pump.

7. Rotate the multi-port valve to actuate the next filter in the system to backwash.

8. Wait as the valve is actuated and the pressure in the multi-port valve

returns to its standard setting.

9. Turn on the pump and follow the steps outlined above for the backwash of this filter.

10. Continue the backwash procedure until each tank in the system has been

backwashed. The filters need not all be backwashed at the same time but when one or more filters is not clean the overall system filtration will not be at its maximum.

11. Once all the filters have been backwashed shut off the feed pump and

return the multi-port to the home position.

12. The system is now ready to begin to filter the pool water.

13. Make sure all the proper valves to the pool and the pump are open.

14. Turn on the pump and begin the filtration process. The system pressure should return to the steady state influent and effluent pressure values of a clean system.


Winterizing the Filter In areas that have freezing winter temperatures it is recommended that the filters be winterized. Winterization Steps

1. Thoroughly backwash each filter to remove foreign contaminates from the filter bed prior to draining the system.

2. Shut off all electrical power to the filter system. This includes the

automatic control system if provided and the pump.

3. Loosen the flange connecting the effluent line to the tank. Then open the manual air relief valve /cap allowing the water to drain out of the filters.

4. When the water is drained from the system manually activate the

backwash valve to drain the backwash line.

5. Shut off the city water to the filter system.

6. Disconnect and drain all control and sensor tubing. Reattach after lines are completely empty.

7. Loosen any flanges in a low-lying section of piping to completely drain the

system of water.

8. Store any plugs removed near the filter and mark all flanges that have been loosened so that they may be reinstalled and tightened at time of start up.
