NIBE™ F1245Chapter 1 | Important information4

Transport
F1245 should be transported and stored vertically in a
dry place. When being moved into a building, F1245
may be leant back 45 °. Note! Can be tail heavy.
TIP
The side panels can be removed for easier in-
stallation in the building.

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 65 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 horizont-
al 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 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.
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. Ap-
prox 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 behind (and any routing of supply cables and
pipes) to reduce the risk reproduction of any vibration.
