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 eliminate

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 free space of 800 mm in front of the product.

Leave free space between NIBE FLM and wall/fit-

tings/cables/pipes etc. It is recommended that a space

of at least 10 mm is left to reduce the risk of noise and

of any vibrations being propagated.

800

NOTE

Ensure that there is sufficient space (300 mm)

above NIBE FLM for installing ventilation

hoses.

NOTE

Venting may be necessary during installation

and after a period of use. Venting takes place

through vent valve (QM21). When venting, set

the switch for the circulation pump (SF2) to

position ”0”.

COMPATIBLE NIBE HEAT PUMPS

NIBE FLM ventilates the building and preheats the brine,

regardless of which ground source heat pump is in-

stalled, but when NIBE FLM is installed together with

a compatible ground source heat pump, it is possible to

adjust settings and read off sensor values etc. in the

heat pump’s display.
