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 69 for instructions about the separation.
Assembly
႑Position the heat pump on a firm base that can bear
its weight, preferably on a concrete floor or founda-
tion. Use the heat pump’s adjustable feet to obtain
a horizontal and stable set-up.
30 - 50 mm
႑The area where the heat pump 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 heat pump.
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.

*Depending on routing of supply cables and pipes.
** A normal installation needs 300 - 400 mm (any side) for connec-
tion of equipment, i.e. level vessel, valves and electrical equipment.
