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.
F1145 must be installed via an isolator
switch. The cable area has to be dimensioned
based on the fuse rating used.

Transport
F1145 should be transported and stored vertically in a
dry place. When being moved into a building, F1145
may be leant back 45 °.
Ensure that F1145 has not been damaged during trans-
port.
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 61 for instructions about the separation.
Assembly
• Place F1145 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
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.

* A normal installation needs 300 – 400 mm (any side) for connection
equipment, i.e. level vessel, valves and electrical equipment.
