FLM 30 is an exhaust air module specially designed tocombine recovery of mechanical exhaust air with anenergy collector in the ground or in rock. FLM 30 is designed to connect to the FIGHTER1110/1210 type of ground heat pump.The integrated fan in FLM 30 extracts the air from thewet areas of the house to the recovery unit. Here theenergy is transferred to the heat pump's brine, where-by the temperature increases and raises the heatpump's heating factor. Energy is stored in the groundor rock collector even if the heat pump is not in opera-tion, which fully utilises the exhaust air energy. The heat pump capacity is not bound by the amount ofair, but the output can be optimally adapted to suit thesize of the house.FLM 30 is positioned directly on FIGHTER 1210, butcan also be mounted using brackets (accessory) onthe wall.

Principle of operation

The exhaust air module’s air filter should be cleanedregularly (about 4-5 times a year) by taking it out andshaking off any dirt. If the filter is very dirty, turn it up-side-down and wash it carefully with water.

■ Open the front cover by pulling it out by the loweredge, then lifting it up.

■ Set the switch (8) to “0”.

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

■ Pull out the holder, take out the filter (63) andshake off any dirt. Check that the filter is not dam-aged. New original filters can be ordered fromNIBE.

■ Assembly takes place in the reverse order.

The interval between cleaning operations varies and depends on the amount of dust in the exhaust air.

FLM 30 and its ventilation ducting require some regu-lar maintenance where the following points should bechecked:

The numbers in brackets refer to the section “List ofcomponents”.

Clean the fan once a year by taking it out of the ex-haust air module and carefully brushing the vanesclean.

■ Open the front cover by pulling it out by the loweredge, then lifting it up.

■ Set the switch (8) to “0”.

■ Dismantle the inner cover by loosening the 6 coverscrews.

■ The fan is removed by disconnecting the fan cableconnector and the two screws as illustrated.

■ Once the inner cover has been removed alsocheck the drip-pan under the heat exchanger. Alsocheck the outlet from the drip-pan (98) to ensure itis not blocked.

■ Assembly takes place in the reverse order.

NOTE! Avoid distorting the fan blades as

this causes imbalance.

Do not use water or detergents.

Maintenance routines 5For Home Owners

FLM 30

Check that there is water in the water seal (92) to thedrip-pan (93). If the water seal is empty or has a verylow water level so that it “gurgles” water can be filled,for example, using a watering can through the drip-pan water hose which then forms a water seal or di-rectly in the drip-pan (the inner cover plate must thenbe dismantled). The water seal is maintained duringfilling.After using for a period of time dust and other particlescan clog the water seal, consequently, you shouldcheck this regularly and clean when necessary.

The ventilation devices in the house should becleaned regularly to maintain the correct ventilation.The device settings must not be changed. NOTE! If you take down more than one ventilation de-vice for cleaning, do not mix them up.

General points for the installation engineer6For the Installation engineer

FLM 30

FLM 30 is installed on FIGHTER 1210 or using brack-ets when connected to FIGHTER 1110. Noise fromthe circulation pump or fan can be transferred to thebrackets. Consequently, mount on an outside wall ifpossible. If it is not possible to mount FLM 30 on anoutside wall avoid a wall connecting to a bedroom orliving-room.NOTE! Ensure that that there is sufficient space (15mm) above the exhaust air module to open the frontcover, see the section “Dimensions”.Route pipework so it is not fixed to an internal wall thatbacks on to a bedroom or living room.

The exhaust air module can contain in-flammable anti-freeze in the brine circuit(for example ethanol). Special careshould be exercised during handling, in-stallation, service, cleaning and scrap-ping to avoid the risk of leakage.

The exhaust air module should be transported andstored in the dry.

FLM 30 features integrated frost protection (65) thatautomatically defrosts the heat exchanger (62) if nec-essary. This is achieved by the brine flow through theheat exchanger being slowed sufficiently so that thewarm room air can thaw the ice. Normally the temperature of the incoming brine toFLM 30 is shown on the display on the frost protec-tion. The frost protection is set at the factory andshould not need adjusting. Changes to the parameterscan result in the heat exchanger becoming blocked byfrost. The buttons are locked with a code.In the event of a fault indication the frost protectionstops the FLM 30 (however, not the ventilation flow).Fault indications on the displayEr Memory fault-- Short circuit temperature sensor (66)00 Defective temperature sensor (66)

Ventilation connection8For the Installation engineer

FLM 30

FLM 30 is connected so that all ventilation air, exceptfor the kitchen fan, passes the heat exchanger (62) inthe exhaust air module. Minimum flow should conformto the demands as set out in applicable norms. Theventilation flow should conform to applicable norms. Switching the ventilation capacity is described in thesection “Electrical installation” “Setting the fan capaci-ty”. The numbering of the curves refers to the terminalblock on the fan transformer (22).

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 are ex-haust air devices in bedrooms.

Connections can be made using flexible hoses, whichshould be stretched well and routed to allow easy re-placement. The extract air duct must be provided withdiffusion-tight insulation over its entire length.Provision must be made for inspection of the duct.Make sure that there are no reductions of cross-sec-tional area in the form of creases, tight bends etc,since this will reduce the ventilation capacity. All joinsin the ducting must be sealed and pop-riveted to pre-vent leakage. The duct system must be carried out inaccordance with current norms. A minimum of airtightness class B is recommended.

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 exhaust air module effi-ciency and thus poorer operating economy, and mayresult in damage to the house.

The diagram below shows the available ventilation ca-pacity.

When FLM 30 is placed directly above the heat pumpthe power supply can be connected to the heatpump’s terminal block. The connection plug musthowever be cut off.If FLM 30 is installed independently (together with aFIGHTER 1110 or if the ceiling level is not highenough to allow placement above 1210) it can be con-nected either to an earthed 1-phase wall socket orthrough permanent installation. When a permanent in-stallation is used, FLM 30 must be preceded by a cir-cuit-breaker.If an insulation test is to be carried out in the building,disconnect the exhaust air module.

■ Open the front cover by pulling it out by the loweredge, then lifting it up.

■ Switch off the voltage by turning the switch (8) to “0”.

■ Remove the securing screw on the electrical boxand pull out the electrical box as illustrated.

■ Select a suitable fan capacity, see below.

■ Assembly takes place in the reverse order.

NOTE! Electrical installation and service

must be carried out under thesupervision of a qualified electrician.

Electrical installation and wiring mustbe carried out in accordance with the

stipulations in force. Work behindscrewed covers may only be carried

Commissioning and adjusting10For the Installation engineer

FLM 30

Start the heat transfer pump on the heat pump, seethe Installation and Maintenance instructions in ques-tion.The brine flow across the FLM 30 is controlled bymeans of the circulation pump (16) and trim valve (81)so that the temperature difference on the brine in andout through FLM 30 is 3 - 4 degrees. Adjustments aremade when the heat pump is running. The tempera-ture difference applies at a room temperature of 20degrees and 0 degrees on the brine.The brine flow through FLM 30 will be from 0.1 l/s (360l/h) to 0.15 l/s (540 l/h) at the above temperature dif-ferences, depending on the ventilation flow. When the heat pump is at a standstill the internal cir-culation pump in FLM 30 gives from 0.085 l/s (306 l/h)to 0.125 l/s (450 l/h) in the return charging flow to thecollector. This applies to a heat pump with an approxi-mate rated output of 4 kW. For a 15 kW heat pump thecorresponding flow is from 0.09 l/s (324 l/h) to 0.14 l/s(504 l/h).

Before commissioning check that the brine circuit isfilled and vented. Check the pipe system for leaks.Check that the brine circuit is pressurised to at least0.5 bar.

Set the switch (38) to 1.Set the switch (8) to 1.Check that the fan and circulation pump are running.

The ventilation flow and correct outlet on the terminalblock (22) are set out on the ventilation drawing.

■ Change the fan capacity by moving the black cableon the 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 air de-vices.

Venting may be necessary after a period of use. Ventusing the venting screw (5). The switch (38) should beset to “0” when venting.
