FLM 30

In order to get the ultimate benefit from your FLM 30

you should read through the For Home Owners sec-

tion in this Installation and Maintenance Instruction.

FLM 30 is an exhaust air module. This means it can

utilise the energy in the ventilation air. The energy is

used to raise the temperature of the ingoing brine to

the heat pump.

FLM 30 is intended to be installed with FIGHTER

1110/1210 in houses or the like.

For Home Owners

FLM 30

System diagram

When the room air has

passed through the exhaust

air module it is discharged.

The temperature has then

dropped as FLM 30 has

utilised the energy in the

room air.

The air from the kitchen

fan goes directly out

into a separate duct.

The warm room

air is led to FLM

30.

FLM 30 increases the

temperature of the brine to the

heat pump.

Outdoor air is

drawn into the house.

The warm room air is

drawn into the air duct

system.

Air is transported

from rooms with

outdoor air devices to

rooms with exhaust

air devices.

FLM 30 is an exhaust air module specially designed to

combine recovery of mechanical exhaust air with an

energy collector in the ground or in rock.

FLM 30 is designed to connect to the FIGHTER

1110/1210 type of ground heat pump.

The integrated fan in FLM 30 extracts the air from the

wet areas of the house to the recovery unit. Here the

energy is transferred to the heat pump's brine, where-

by the temperature increases and raises the heat

pump's heating factor. Energy is stored in the ground

or 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 of

air, but the output can be optimally adapted to suit the

size of the house.

FLM 30 is positioned directly on FIGHTER 1210, but

can also be mounted using brackets (accessory) on

the wall.

Principle of operation

The exhaust air module’s air filter should be cleaned

regularly (about 4-5 times a year) by taking it out and

shaking 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 lower

edge, then lifting it up.

■ Set the switch (8) to “0”.

■ Release the filter holder by turning the two black

knobs a quarter of a turn anticlockwise.

■ Pull out the holder, take out the filter (63) and

shake off any dirt. Check that the filter is not dam-

aged. New original filters can be ordered from

NIBE.

■ Assembly takes place in the reverse order.

The interval between cleaning operations varies and

depends on the amount of dust in the exhaust air.

Maintenance routines4

For Home Owners

FLM 30

LEK

TRYCK

DRAG

FLM 30 and its ventilation ducting require some regu-

lar maintenance where the following points should be

checked:

The numbers in brackets refer to the section “List of

components”.

Clean the fan once a year by taking it out of the ex-

haust air module and carefully brushing the vanes

clean.

■ Open the front cover by pulling it out by the lower

edge, then lifting it up.

■ Set the switch (8) to “0”.

■ Dismantle the inner cover by loosening the 6 cover

screws.

■ The fan is removed by disconnecting the fan cable

connector and the two screws as illustrated.

■ Once the inner cover has been removed also

check the drip-pan under the heat exchanger. Also

check the outlet from the drip-pan (98) to ensure it

is 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

For Home Owners

FLM 30

Check that there is water in the water seal (92) to the

drip-pan (93). If the water seal is empty or has a very

low 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 then

be dismantled). The water seal is maintained during

filling.

After using for a period of time dust and other particles

can clog the water seal, consequently, you should

check this regularly and clean when necessary.

The ventilation devices in the house should be

cleaned 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 engineer6

For the Installation engineer

FLM 30

FLM 30 is installed on FIGHTER 1210 or using brack-

ets when connected to FIGHTER 1110. Noise from

the circulation pump or fan can be transferred to the

brackets. Consequently, mount on an outside wall if

possible. If it is not possible to mount FLM 30 on an

outside wall avoid a wall connecting to a bedroom or

living-room.

NOTE! Ensure that that there is sufficient space (15

mm) above the exhaust air module to open the front

cover, see the section “Dimensions”.

Route pipework so it is not fixed to an internal wall that

backs 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 care

should be exercised during handling, in-

stallation, service, cleaning and scrap-

ping to avoid the risk of leakage.

The exhaust air module should be transported and

stored in the dry.

Alt. 1

Alt. 2

FLM 30 features integrated frost protection (65) that

automatically defrosts the heat exchanger (62) if nec-

essary. This is achieved by the brine flow through the

heat exchanger being slowed sufficiently so that the

warm room air can thaw the ice.

Normally the temperature of the incoming brine to

FLM 30 is shown on the display on the frost protec-

tion. The frost protection is set at the factory and

should not need adjusting. Changes to the parameters

can result in the heat exchanger becoming blocked by

frost. The buttons are locked with a code.

In the event of a fault indication the frost protection

stops the FLM 30 (however, not the ventilation flow).

For the Installation engineer

The condensation water hose is routed directly to the

floor drain or other water seal. Ensure that the end of

the hose runs out above the water level in the floor

drain. The pipe installation must be carried out in ac-

cordance with current norms.

sioned as set out in the diagram, to prevent operating

disturbances. The pressure expansion vessel covers

the temperature range from -10 °C to +20 °C at a pre-

pressure of 0.5 (bar) and the safety valve’s opening

Ventilation connection8

For the Installation engineer

FLM 30

FLM 30 is connected so that all ventilation air, except

for the kitchen fan, passes the heat exchanger (62) in

the exhaust air module. Minimum flow should conform

to the demands as set out in applicable norms. The

ventilation flow should conform to applicable norms.

Switching the ventilation capacity is described in the

section “Electrical installation” “Setting the fan capaci-

ty”. The numbering of the curves refers to the terminal

block on the fan transformer (22).

To prevent fan noise being transferred to the exhaust

air devices, it may be a good idea to install a silencer

in the duct. This is especially important if there are ex-

haust air devices in bedrooms.

Connections can be made using flexible hoses, which

should be stretched well and routed to allow easy re-

placement. The extract air duct must be provided with

diffusion-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 joins

in the ducting must be sealed and pop-riveted to pre-

vent leakage. The duct system must be carried out in

accordance with current norms. A minimum of air

tightness class B is recommended.

To obtain the necessary air exchange in every room of

the house, the exhaust air devices must be correctly

positioned and adjusted. A defective ventilation instal-

lation may lead to reduced exhaust air module effi-

ciency and thus poorer operating economy, and may

result in damage to the house.

The diagram below shows the available ventilation ca-

pacity.

When FLM 30 is placed directly above the heat pump

the power supply can be connected to the heat

pump’s terminal block. The connection plug must

however be cut off.

If FLM 30 is installed independently (together with a

FIGHTER 1110 or if the ceiling level is not high

enough to allow placement above 1210) it can be con-

nected either to an earthed 1-phase wall socket or

through 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 lower

edge, then lifting it up.

■ Switch off the voltage by turning the switch (8)

to “0”.

■ Remove the securing screw on the electrical box

and 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 the

supervision of a qualified electrician.

Commissioning and adjusting10

For the Installation engineer

FLM 30

Start the heat transfer pump on the heat pump, see

the Installation and Maintenance instructions in ques-

tion.

The brine flow across the FLM 30 is controlled by

means of the circulation pump (16) and trim valve (81)

so that the temperature difference on the brine in and

out through FLM 30 is 3 - 4 degrees. Adjustments are

made when the heat pump is running. The tempera-

ture difference applies at a room temperature of 20

degrees and 0 degrees on the brine.

The brine flow through FLM 30 will be from 0.1 l/s (360

l/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 the

collector. This applies to a heat pump with an approxi-

mate rated output of 4 kW. For a 15 kW heat pump the

corresponding 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 is

filled and vented.

Check the pipe system for leaks.

Check that the brine circuit is pressurised to at least

0.5 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 terminal

block (22) are set out on the ventilation drawing.

■ Change the fan capacity by moving the black cable

on the terminal block (22) if necessary. Use the

lowest possible output to obtain the lowest noise

levels.

■ 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. Vent

using the venting screw (5). The switch (38) should be

set to “0” when venting.
