AssemblyThe water heater is only designed for upright installa-tion.
Position the water heater on a firm base that can bearits weight, preferably on a concrete floor or founda-tion. Use the water heater’s adjustable feet to obtaina horizontal and stable set-up.
Pipes must be routed from the safety valve to a suit-able floor drain.
Installation area
Approx 425 mm free space is required on the left sideand in front of the water heater in order to replace theimmersion heater.

9Chapter 3 | The water heater designVPB 200N
GeneralPipe installation must be carried out in accordance withcurrent norms and directives.
Internal support bushes should be fitted when a plasticpipe or annealed copper pipe is used. The water heatermust be fitted with the requisite valves, such as a safetyvalve, shut-off valve, non-return valve, and vacuum valve.An overflow pipe must be routed from the safety valveto a suitable drain. The size of the overflow pipe must bethe same as on the safety valve. Route the overflow pipefrom the safety valve enclosed along its entire length andensure that it is frost proof. The outlet of the overflowpipe should be visible and clearly away from any electricalcomponents.
Overflow water from the safety valves goes via non-pressurised collecting pipes to a drain so that hot watersplashes cannot cause injury. These non-pressurised col-lecting pipes shall not be used for anything else. A dis-charge pipe from the tundish connected to the expansionrelief valve (safety valve) shall also be connected to a drainin the same way.
Please note that the connection of the T&P-valve shouldnot be used for any other purpose.
Valves may not be positioned between the expansionvalve and the vessel.
Discharge pipes from tundishes shall have av verticalsection of pipe at least 300 mm long, before any elbowsor bends in the pipework (see following picture).

Hard water areas
Usually, there should not be a problem in installing VPB200N in areas of hard water as the operating temperatureis 50-60 °C.
Cleaning the climate system
When the water heater and the climate system have beenfilled with water, VPB 200N must operate at maximumnormal temperature for at least one hour. Thereafter thesystem must be drained of water and refilled.
Emptying the system by
1. Open the filling valve and the drain valve for the cli-mate system.
2. Flush the system for some minute. Watch out forwater splashes from the safety valve.
3. Close the valves and check the stainer.

Cold and hot waterConnecting cold and hot water
There must be a mixing valve if the temperature can ex-ceed 60 °C.
The flexible hose to the expansion vessel can be installedin the plugged connection on the safety valve.
11Chapter 4 | Pipe connectionsVPB 200N
Connecting hot water circulation
VPB 200N has a connection that allows hot water circu-lation.
To reduce the risk of bacterial growth in systems withhot water circulation, the temperature of the circulatingwater should not fall below 50 °C. There should not beany non-circulatory hot water pipes. Adjust the hot watersystem so that the temperature does not fall below 50°C at the ends of the system.
Installation alternativeVPB 200N can be connected in several different ways,one of which is shown here.
Further option information is available at www.nibe.co.ukand in the respective assembly instructions for the heatpumps used.

NOTE
Electrical installation and service must be carriedout under the supervision of a qualified electri-cian. Electrical installation and wiring must becarried out in accordance with the stipulationsin force.
SensorsVPB 200N can be supplemented with up to two hot watersensors, one for display and one for control. The displaysensor is positioned in the submerged tube for the displaysensor (UA1) and the control sensor in the submergedtube for control sensor (UA2). In cases where it is onlypossible to connect one sensor, use the submerged tubefor control sensor (UA2).
NOTE
Use the supplied heat conducting paste whenpositioning the sensor in the submerged tube(UA2) and ensure that the sensor is in the sub-merged tube fully and that the cover disc issealed.
The bulb for the temperature limiter is in the submergedtube for the display sensor. Any sensors must be installedabove the bulb.
Use the sensors provided with the heat pump/controlmodule. When no heat sensors have been provided thesemust be ordered from the manufacturer of the heatpump/control module.

Install the temperature sensor using heat conductingpaste.
Temperature limiterElectrical supply to the temperature limiter (FD1) is 230V. Connect the temperature limiter as follows:
1. Connect the temperature limiter (FD1) electrical tothe magnetic shut off valve.
Immersion heaterPower supply to the immersion heater (EB1) is 230 V. Theimmersion heater's thermostat must be set to 5 (68 °C).

NOTE
At the time of commissioning, complete all rel-evant sections of the Benchmark Checklist loc-ated at the back of this document.Completion of the Benchmark Checklist is acondition of warranty. For full terms and condi-tions of warranty, please see our websitewww.nibe.co.uk.
Filling and ventingFilling the hot water heater
1. Open a hot water tap in the house.
2. Fill the hot water heater through the cold waterconnection (XL3).
3. When the water that comes out of the hot water tapis no longer mixed with air, the water heater is fulland the tap can be closed.
Filling and venting the climate system
Filling1. Open the filling valve (external, not included with the
product). Fill the coil in the hot water heater and therest of the climate system with water.
2. Open the external venting valve.
3. When the water that exits the external venting valveis not mixed with air, close the valve. After a whilethe pressure starts to rise.
4. Close the filling valve when the correct pressure isobtained.
Venting1. Vent the climate system via the relevant venting
valves.
2. Keep topping up and venting until all air has beenremoved and the pressure is correct.

Adjustment, charge flow FIGHTER 2015
Adjusting the temperature difference ( T) between theheat pump's supply and return temperature is importantto maintain optimal operational economy.
The charge flow can be adjusted using the heat pump'ssupply and return temperatures.
The difference between channel T2 (flow temperature))and channel T3 (return temperature) is adjusted usingthe circulation pump and control valve.
Adjustment is made when the flow temperature is approx.45 ºC and at stable operation, 5 minutes after start-upor 5 minutes after defrost.
