Water may drip from the safety valve’s

overflow pipe. The entire length of the over-

flow water pipe must be routed to a suitable

drain and be inclined to prevent water pock-

ets, and must also be frost-proof. The over-

flow pipe must be at least the same size as

the safety valve. The overflow pipe must be

visible and its mouth must be open and not

located close to electrical components.

F1145PC must be installed via an isolator

switch. The cable area has to be dimensioned

based on the fuse rating used.

Transport

F1145PC should be transported and stored vertically in

a dry place. When being moved into a building, F1145PC

may be leant back 45 °.

Ensure that F1145PC has not been damaged during

transport.

Caution

The product can be tail heavy.

If the cooling module is pulled out and transported up-

right, F1145PC 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 57 for instructions about the separation.

Assembly

• Place F1145PC on a solid foundation indoors that can

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

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

30 - 50 mm

15 - 40 mm

20-55 mm

• Because water comes from F1145PC, 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

F1145PC 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.

(50) (50)

800

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

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