NIBE™ F1255Chapter 1 | Important information6

Transport

F1255 should be transported and stored vertically in a

dry place. When being moved into a building, F1255

may be leant back 45 °.

Caution

The product can be tail heavy.

Remove the outer panels in order to protect them when

moving in confined spaces inside buildings.

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 55 for instructions about the separation.

Assembly

■Position F1255 on a solid foundation that tolerates

the weight of the heat pump. Use the product's ad-

justable feet to obtain a horizontal and stable set-up.

30 - 50 mm

15 - 40 mm

■Because water comes from F1255, the area where the

heating pump is located must be equipped with floor

drainage.

■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 free space of 800 mm in front of the product. Ap-

prox. 50 mm free space is required on each side (see

image) in order to remove the side panels. The panels

do not need to be removed during service. All service on

F1255 can be carried out from the front. Leave space

between the heat pump and the wall behind (and any

routing of supply cables and pipes), to reduce the risk of

transmission of any vibrations.

* A normal installation needs 300 – 400 mm (any side) for connec-

tion equipment, i.e. level vessel, valves and electrical equipment.
