Transport
S1255 should be transported and stored vertically in a dry
place. When being moved into a building, S1255 may be leant
back 45 °.
Ensure that S1255 has not been damaged during transport.
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 cabin-
et.
See page 59 for instructions about the separation.
Assembly
• Place S1255 on a solid foundation indoors that can take
the heat pump’s weight.
Use the product’s adjustable feet to attain a horizontal
and stable set-up.
30 - 50 mm
30 - 50 mm
15 - 40 mm
• Because water comes from S1255, 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. Ap-
prox. 50 mm free space is required on each side, to allow
the side panels to be removed (see image). All service on
S1255 can be carried out from the front, however the right-
hand panel may need to be removed. Leave free space
between the heat pump and the wall behind (and any routing
of supply cables and pipes), to reduce the risk of any vibra-
tions being propagated.
* A normal installation needs 300 – 400 mm (any side) for
connection equipment, e.g. level vessel, valves and electrical
equipment.
