NIBE FLMChapter 1 | Important information4

Transport
The exhaust air module should be transported and
stored in the dry.
Assembly
NIBE FLM is installed on top of the ground heat pump
or freestanding on brackets. Noise from the circulation
pump or fan can be transferred to the brackets.
■Install with its back to an outside wall, ideally in a
room where noise does not matter, in order to elim-
inate noise problems. If this is not possible, avoid
placing it against a wall behind a bedroom or other
room where noise may be a problem.
■Wherever the unit is located, walls to sound sensitive
rooms should be fitted with sound insulation.
■Route pipes so they are not fixed to an internal wall
that backs on to a bedroom or living room.
Installation area
Leave a space of 500 mm in front of the exhaust air
module. Approximately 50 mm free space is required
on each side in order to open the side hatches. The
hatches do not need to be opened during service, all
service on NIBE FLM can be carried out from the front.

Expansion vessel
The brine circuit must be supplied with a pressure ex-
pansion vessel (CM3). If there is already a level vessel
(CM2) installed this should be replaced. The brine side
must be pressurised to at least 0.5 bar.
The pressure expansion vessel should be dimensioned
as set out in the diagram, to prevent operating disturb-
ances. The pressure expansion vessel covers the tem-
perature range from -10 °C to +20 °C for the brine at
a pre-pressure of 0.5 bar and the safety valve's opening
pressure of 3 bar.

Condensation water hose
1. Connect the condensation water hose to the drip-
pan drain (XL40).
2. Shape the hose into a water seal (see image). If
NIBE FLM is connected to F1245/F1255 there is
space for the hose and the water seal in the heat
pump's insulation.
3. Route the hose to a floor drain or similar.
4. Refill the water seal with water.
Ensure that the end of the hose runs out above the
water level in the floor drain. The hose must be easily
accessible for future cleaning.

An external fan has taken over ventilation, which is led
out of the house without recovery.
At the same time, FLM circulates air from a substantial
exhaust air valve in, for example, a hall to the other
rooms where cooling is required, normally two to three
bedrooms.
Passive cooling requires room sensors in the rooms
where cooling is to be maintained.
NOTE
The supply air ducts must be insulated for
passive cooling using diffusion-proof material
(PE30) along their entire lengths.
13Chapter 4 | Pipe and ventilation connectionsNIBE FLM

General ventilation connection
Ventilation installation must be carried out in accord-
ance with current norms and directives.
To prevent fan noise being transferred to the ventila-
tion devices, it may be a good idea to install a silencer
in the duct. This is especially important if there are
ventilation devices in noise sensitive rooms.
Connections must be made via flexible hoses, which
must be installed so that they are easy to replace. The
extract air duct must be provided with diffusion-tight
insulation (PE30) over its entire length. Ensure that the
condensation insulation is sealed at any joints and/or
at lead-in nipples, silencers, roof cowls or similar. Provi-
sion must be made for inspection and cleaning of the
duct. Make sure that there are no reductions of cross-
sectional area in the form of kinks, tight bends etc.,
since this will reduce the ventilation capacity. The air
duct system must be a minimum of air tightness class
B.
Exhaust air duct /kitchen fan
Exhaust air duct (kitchen fan) must not be connected
to NIBE FLM.
To prevent food vapour being transferred to NIBE FLM
the distance between the kitchen fan and the exhaust
air device must be considered. The distance should not
be less than 1.5 m, but this can vary between different
installations.
Always use a kitchen fan when cooking.
NOTE
A duct in a masonry chimney stack must not
be used for extract air.

LEK
Extract air
Exhaust air
Ventilation flow
Connect NIBE FLM so that all exhaust air except exhaust
air duct air (kitchen fan) passes the heat exchanger
(EP1) in the exhaust air module. Lowest ventilation flow
must comply with applicable standards. For optimum
exhaust air module performance the ventilation flow
should not be less than 25 l/s (90 m³/h). On occasions
when the exhaust air temperatures are lower than 20
°C (for example on start-up and when there is no one
at home) the minimum value is 31 l/s (110 m³/h).
Ensure that the ventilation openings are not blocked.
If the exhaust air module is connected to
F1145/F1155/F1245/F1255 set the ventilation capacity
in the heat pump's menu system (menu 5.1.5). Other-
wise the ventilation capacity is set via potentiometer
(AA5-SF3).
Adjusting ventilation
To obtain the necessary air exchange in every room of
the house, the exhaust air devices must be correctly
positioned and adjusted and the fan in the exhaust air
module adjusted.
Immediately after installation adjust the ventilation so
that it is set according to the projected value of the
house.
A defective ventilation installation may lead to reduced
installation efficiency and thus poorer operating eco-
nomy, and may result in moisture damage to the house.
NIBE FLMChapter 4 | Pipe and ventilation connections14

General
All electrical equipment is connected at the factory.
■Disconnect NIBE FLM before insulation testing the
house wiring.
■For the exhaust air module wiring diagram, see page
30.
■Signal cables to external connections must not be
laid close to high current cables.
■If the supply cable is damaged, only NIBE, its service
representative or similar authorised person may re-
place it to prevent any danger and damage.
NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician. Electrical installation and wiring
must be carried out in accordance with the
stipulations in force.
Connections
F1345 has different electrical connection versions de-
pending on when the heat pump was manufactured.
To check which electrical connection applies to your
F1345, check the designation "2.0" visible above the
right hand side of the terminal block as illustrated.
