NIBE™ F1245Chapter 1 | Important information4

Pulling out the cooling module
To simplify transport and service, the heat pump can be
separated by pulling the cooling module out from the
cabinet.
See page 58 for instructions about the separation.
Assembly
႑Position F1245 on a firm base that can take the weight,
preferably on a concrete floor or foundation. Use the
product's adjustable feet to obtain a horizontal and
stable set-up.
30 - 50 mm
႑The area where F1245 is located must be equipped
with floor drainage.
႑Install 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.
႑Wherever the unit is located, walls to sound sensitive
rooms should be fitted with sound insulation.
႑Route 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 800 mm in front of the product. Approx
50 mm free space is required in order to open the side
hatches. The hatches do not need to be opened during
service, all service on F1245 can be carried out from the
front. Leave space between the heat pump and wall be-
hind (and any routing of supply cables and pipes) to re-
duce the risk reproduction of any vibration.
