Transport

F1255PC BE should be transported and stored vertically

in a dry place. When being moved into a building,

F1255PC BE 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.

EXTRACTING 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 54 for instructions about the separation.

Assembly

• Position F1255PC BE on a fixed foundation that can

take the weight of the heat pump. Use the product's

adjustable feet to obtain a horizontal and stable set-

up.

30 - 50 mm

15 - 40 mm

20-55 mm

• Because water comes from F1255PC BE, 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 a free space of 800 mm in front of the product.

Approx. 50 mm free space is required on each side, to

remove the side panels (see image). The panels do not

need to be removed during service. All service on

F1255PC BE 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 any vibration being propagated.

800

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

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