NIBE™ F1255Chapter 1 | Important information4

Transport

F1255 should be transported and stored vertically in a

dry place. When being moved into a building, F1255

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 58 for instructions about the separation.

Assembly

႑Position F1255 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 F1255 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 F1255 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.
