Transport

F1145 should be transported and stored vertically in a

dry place. When being moved into a building, F1145

may be leant back 45 °.

Caution

The product can be tail heavy.

If the cooling module is pulled out and transported up-

right, F1145 can be transported on its back.

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 58 for instructions about the separation.

Assembly

■Position F1145 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 F1145, 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 F1145

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 vibra-

tion being propagated.

(50) (50)

800

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

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