In order to get the ultimate benefit from your heatpump FIGHTER 360P you should read through thisInstallation and Maintenance Instruction.

FIGHTER 360P is an exhaust air heat pump. Thismeans that it collects the energy in the ventilation air and uses it for hot water and roomheating.

Microprocessors ensure that the heat pump alwaysworks efficiently.

FIGHTER 360P is a Swedish-made quality productwhich will last a long time and run reliably without unpleasant surprises.

For Home Owners

System description 3For Home Owners

FIGHTER 360P

FIGHTER 360P comprises an electric boiler with acopper lined water heater and a heat pump whichrecovers energy from the ventilation air. The recov-ered energy is supplied to the heat pump. The heatpump must be installed in a ventilation system intend-ed for mechanical exhaust air.

The output of the immersion heater is max 13.5 kW(Supplied output of 7.5 kW).

When the exhaust air at room temperature passesthrough the evaporator, the refrigerant evaporatesbecause of its low boiling point. In this way the heat inthe room air is transferred to the refrigerant.

The refrigerant is then compressed in a compressor,causing the temperature to rise considerably.

The warm refrigerant is fed to the condenser, which isin the boiler water. Here the refrigerant gives off itsheat to the boiler water, so that its temperature dropsand the refrigerant changes state from gas to liquid.

The refrigerant then goes via filters to the expansionvalve, where the pressure and temperature are furtherreduced.

The refrigerant has now completed its circulation andreturns to the evaporator.

Automatic heating control systemThe indoor temperature depends on several factors.During the hot season, solar radiation and heat givenoff by people and equipment are sufficient to keep thehouse warm. When it gets colder outside, the heatingsystem must be started. The colder its gets, the hotterthe radiators must be.

This adjustment is made automatically, however thebasic settings must first be made on the boiler, see thesection Room temperature — Default setting.

The basic heating is set using menu 2.4 and with theOffset heating curve knob.

If you do not know the correct settings use the basicdata from the map opposite.

If the required room temperature is not obtained, read-justment may be necessary.

NOTE! Wait one day between settings so that the tem-peratures have time to stabilise.

Readjustment of basic settings.

Cold weather conditionsWhen the room temperature is too low, the heatingcurve value is increased in menu 2.1 by one incre-ment.

When the room temperature is too high, the heatingcurve value is decreased in menu 2.1 by one incre-ment.

Warm weather conditionsIf the room temperature is low, increase the offsetheating curve setting by one step.

If the room temperature is high, reduce the offsetheating curve setting by one step.

Changing the room temperature manually.

If you want to temporarily or permanently lower orraise the indoor temperature relative to the previouslyset temperature, turn the Offset heating curve knobanticlockwise or clockwise. One to three lines approxi-mately represents a 1 degree change in room tempera-ture.

NOTE! An increase in the room temperature may beinhibited by the radiator or floor heating thermostats, ifso these must be turned up.

The values stated on the map apply for the “Heatingcurve selection”.

The first value applies for low temperature * radiatorsystems. “Heating curve offset” is set to -2.

The value in brackets refers to floor heating systems**installed in concrete floor structures. When the systemis Installed in a timber floor structure you can use thenumber before the brackets, but this value must bereduced by two units. In these cases the “Heatingcurve offset” is set to -1.

The map values are usually a good starting point andconcern an approximate room temperature of 20°C.The values can be adjusted later if necessary.

Basic values for the automatic heating control systemThe lower values in the north of Sweden are due tothe lower design outdoor temperature.

Clean the fan every other year by taking it out of theheat pump and carefully brushing the vanes clean.

Set the switch to “0”.

Open the upper front cover by pulling it out by thelower edge, then lifting it up.

To open the inner cover, unscrew the screws inthe outer edges of the cover.

The fan is removed by unscrewing the four screwsas illustrated and disconnecting the fan cable con-nector.

After removing the fan check the condensationtray under the evaporator. At the same time,check that the condensation hose connection isnot blocked.

Assembly takes place in the reverse order.

The heat pump's air filter needs to be cleaned regular-ly (approximately 4 — 5 times per year). The intervalbetween cleaning operations varies and depends onthe amount of dust in the exhaust air.

Set the switch to “0”.

Open the upper front cover by pulling it out by thelower edge, then lifting it up.

Release the filter holder by turning the two blackknobs a quarter of a turn anticlockwise.

Pull out the holder, take out the filter and shake offany dirt. If the filter is very dirty, turn it upside-down and wash it carefully with water.

Check that the filter is not damaged. New originalfilters can be ordered from NIBE.

Assembly takes place in the reverse order.

Check that the temperature of the extract air (menu4.2) is clearly lower than the room temperature whenthe compressor is operational, also see section Deal-ing with malfunctions — High extract air temperature.It is normal that the extract air temperature varies.

The working range of the heating system is normally0.5 — 1.5 (bar) Check this on the pressure gauge(42).

FIGHTER 360P has two safety valves, one for theheating system and one for the water heater.

The heating system’s safety valve (52) must be com-pletely tight, but the hot water safety valve (47) mayoccasionally release some water after hot water hasbeen used. This is because the cold water, whichenters the water heater to replace the hot water,expands when heated causing the pressure to riseand the safety valve to open.

Check both the pressure relief valves regularly. Check one valve at a time as follows:

Open the valve.

Check that water flows through the valve.

Close the valve. The heating system may need to be refilled after

checking the safety valve (52), see the sectionCommissioning and adjustment — Filling the heat-ing system.

General information for the installer 11

FIGHTER 360P

Current regulations require the heating installation tobe inspected before it is commissioned. The inspec-tion must be carried out by a suitably qualified person.The above applies to installations with a closedexpansion vessel. A new inspection must be madewhen changing the heat pump or the expansion ves-sel.

The heat pump should preferably be erected with itsback about 10 mm from an outside wall in a utilityroom or similar, to minimise noise nuisance. If this isnot possible, a wall that backs on to a bedroom orsome other room where noise would be a problemshould be avoided. Irrespective of the placement thewall should be sound insulated. NOTE! The distancebetween the heat pump and the wall should be atleast 10 mm.

Route pipes so they are not fixed to an internal wallthat backs on to a bedroom or living room.

FIGHTER 360P should be transported and stored ver-tically in the dry. The FIGHTER 360P may however becarefully laid on its back when being moved into abuilding.

The heat pump contains highly inflam-mable refrigerant. Special care shouldbe exercised during handling, installa-tion, service, cleaning and scrapping toavoid damage to the refrigerant systemand in doing so reduce the risk of leak-age.

Inspection of the installation

The volume of the expansion vessel (85) is 12 litresand it is pressurised as standard to 0.5 bar (5 mvp).As a result, the maximum permitted height H betweenthe vessel and the highest radiator is 5 metres; seefigure. If the standard initial pressure in the pressurevessel is not high enough it can be increased byadding air via the valve in the expansion vessel. Theinitial pressure of the expansion vessel must be statedin the inspection document. Any change in the initialpressure affects the ability of the expansion vessel tohandle the expansion of the water. The maximum sys-tem volume excluding the boiler is 285 litres at theabove initial pressure.

For the Installer

NOTE!Work on the refrigerant system mustbe done by authorised personnel in

accordance with the relevantlegislation on refrigerants, sup-

plemented by additional requirementsfor flammable gas, for example,

product knowledge as well as serviceinstruction on gas systems with

flammable gases.

The unit can be used exclusively as an electric boiler,to produce heat and hot water, for example before thecollector installation is complete.

Three different operating modes are possible.

Option 1. Electric boiler mode with ventilationSelect menu 8.31 Electric boiler. Activate Yes.Option 2. Electric boiler mode without ventilationSelect menu 8.31 Electric boiler. Activate Yes.Activate fan Off using the Fan speed push button.Option 3. Standby mode “ ”

This mode is used when an outdoor sensor is not con-nected. The heat pump's compressor and electroniccontrol are disabled in the “ ” position.

The fan is operational (speed I) and the immersionheater is controlled by a separate thermostat.

The numerical display is off. The automatic heatingcontrol system is not operational, so manual shuntoperation is required. This is performed by pressing inthe shunt motor knob and then turning it to the pre-ferred position.

NOTE! When returning to normal mode do

not forget to reset the shunt knob to itsoriginal position by turning the knob

until it “jumps out”.

Pipe connections

FIGHTER 360P

12

Pipe installation must be carried out in accordancewith current norms and directives.

The system requires a low-temperature design of theradiator circuit. At DUT, the highest recommendedtemperatures are 55 °C on the supply line and 45 °Con the return line.

When the circulation pump is running, the flow in theradiator circuit must not be completely stopped. In oth-er words, in a system where the radiator flow mightstop because all thermostat valves are closed, theremust be a bypass valve to protect the circulationpump.

The total volume is 240 litres, with 170 litres in thewater heater and 70 litres in the double-jacket space.

The pressure vessel in the FIGHTER 360P isapproved for max 9.0 bar (0.9 MPa) in the waterheater and 2.5 bar (0.25 MPa) in the double jacketspace.

Overflow water from the evaporator collection tray andsafety valves goes via non-pressurised collectingpipes to a drain so that hot water splashes cannotcause injury.

Other heat sources can be docked to the FIGHTER360P Accessories are needed. Contact NIBE AB forinformation.

General Docking

NOTE!The pipe work must be flushed

before the heat pump is connected,so that any contaminants do notdamage the component parts.

For the Installer

To empty the water heater proceed as follows:

Disconnect the overflow pipe from the drain con-nection (79) and connect a hose to a drainingpump instead. Where no draining pump is avail-able, the water can be released into the overflowfunnel (99).

Open the safety valve (47).

Open a hot water tap to let air into the system. Ifthis is not enough, undo a pipe coupling (74) onthe hot water side and pull out the pipe.

The hot water can be drained off through drain valve(51) using an R15 (1/2") hose coupling. Remove thecover (80) from the valve. Now screw on the hosecoupling and open valve (51).

Open safety valve (52) to let air into the system.

Draining the heating systemEmptying the water heater

Hot and cold water are connected to pos (74) (hotwater) and (73) (cold water).

The heat pump should be supplemented with an elec-tric water heater if a bubble pool or other significantconsumer of hot water is installed.

Ventilation connection

FIGHTER 360

For the Installer

14

FIGHTER 360P is connected so that all ventilation airexcept the kitchen fan passes the evaporator (62) inthe heat pump. The lowest ventilation flow accordingto current standards is 0.35 l/s per m2 floor area. Foroptimum heat pump performance the ventilation flowshould not be less than 110 m3/h. (31 l/s).

The heat pump's installation area should be ventilatedby at least 36 m3/h (10 l/s).

FIGHTER 360P is equipped with a ventilationopening in the base. As a result, an air flow of about 5m3/h (1,4 l/s) is taken directly from the room where theheat pump is installed.

Changing the ventilation capacity is described underElectrical connection - Setting the fan capacity. Seealso Circuit diagram. The numbering of the curvesrefers to the numbering on the fan terminal block (22).

To obtain the necessary air exchange in every room ofthe house, the exhaust air devices must be correctlypositioned and adjusted. A defective ventilation instal-lation may lead to reduced heat pump efficiency andthus poorer operating economy, and may result indamage to the house.

NOTE!A duct in a masonry chimney stack

must not be used for extract air.

To prevent fan noise being transferred to the exhaustair devices, it may be a good idea to install a silencerin the duct. This is especially important if there areexhaust air devices in bedrooms.

As the heat pump contains a flammable refrigerant inthe form of propane (R290), the air ducting systemmust be earthed. This is done by making a soundelectrical connection to the exhaust air and vented airducts with the two earthing cables supplied. Thecables must then be connected to the earthing studson top of the top cover.

Connections should be made via flexible hoses, whichmust be installed so that they are easy to replace. Theextract air duct must be provided with diffusion-tightinsulation over its entire length. Provision must bemade for inspection of the duct. Make sure that thereare no reductions of cross-sectional area in the formof creases, tight bends etc, since this will reduce theventilation capacity. All joins in the ducting must besealed and pop-riveted to prevent leakage.

The air duct system should, at a minimum, be of airtightness class B.

The diagram below shows the available ventilation capacity.

Keep topping up and venting until all air has beenremoved and the pressure is correct.

Check that the switch (8) is set to 0.

Check that valves (44) and (50) are fully open andthat the temperature limiter (6) has not tripped (pressthe button firmly).

Fill the condensation water hose (97) with a little waterto prevent it making a noise. This is done by looseningthe hose which is located on the waste water pipe (98)and pouring water in the end of the hose so a waterseal arises. Refit the hose.

Venting the heating system

Starting

Preparations

The water heater is filled by first opening a hot water tap and then opening the filling

valve (46) fully. This valve should then remain fully open. When water comes out of the hot water tap, it can be closed. Open the filling valve (49). The boiler part of the

heat pump and the radiator system are now filledwith water.

After a while the pressure gauge (42) will show ris-ing pressure. When the pressure reaches 2.5 (bar)(approx. 25 mvp) a mixture of air and water startsto emerge from the safety valve (52). The filling valve then closed (49).

Turn the safety valve (52) until the boiler pressurereaches the normal working range (0.5 - 1.5 bar).

Filling the water heater and the heating system

Set the switch (8) to 1. When the exhaust air tempera-ture drops below 16 °C the compressor does not start.The immersion heater is then used for heating. Whenthe exhaust air temperature exceeds 16 °C the com-pressor is permitted to start automatically.

FIGHTER 360P

For the Installer

Air is initially released from the hot water and ventingmay be necessary. If bubbling sounds can be heardfrom the heat pump, the entire system requires furtherventing. NOTE! Safety valve (52) also acts as a man-ual venting valve. Operate it with care, since it opensquickly. When the system is stable (correct pressureand all air eliminated) the automatic heating controlsystem can be set as required. See the section Roomtemperature - Setting the Automatic heating controlsystem and Front panel.

ReadjustmentThe ventilation flow and correct outlet on the fan termi-nal block (22) are set out on the ventilation drawing.

Change the fan capacity by moving the grey cableon the fan terminal block (22) if necessary. Use thelowest possible output to obtain the lowest noiselevels.

Make sure that all outdoor air devices are fully open.

Set correct ventilation flows on the exhaust airdevices.

Now move the white and brown cables to obtain therequired exhaust air flow for fan speeds I and II. Thewhite cable corresponds to position I and the brownposition II. Note however that the exhaust air flowmust never fall below 110 m3/h (31 l/s).

Setting the ventilation

The ventilation capacity is selected by moving thebrown, grey and white cables to an appropriate outleton the terminal block (22). See the section, Ventilationconnection - Fan diagram to choose appropriate con-nections.

The grey cable corresponds to the fan speed in nor-mal mode. The white cable corresponds to speed I. The brown cable corresponds to speed II.Example:Normal: Lowest possible fan speed is chosen to

obtain the planned ventilation flow (greycable).

Speed II: Highest possible fan speed is chosen, (forced) however consider ventilation noise (brown

cable).Speed I Lowest possible fan speed is chosen (reducing) where the min flow is maintained (white

cable).
