Assembly
6.1 General
The following connections need to be established on the heat
pump:
- Fresh and exhaust air
- Flow and return of the heating system
- Communication line (heat pump manager)
- Control voltage line (heat pump manager)
- Supply voltage line (electrical distribution system)
- Condensate outflow
6.2 Air connection
NOTE
Do not restrict or block the area around the intake or the air
outlet area.
NOTE
Only operate the heat pump with the air ducts connected.
The glass fibre reinforced concrete air ducts offered as acces-
sories are moisture-resistant and diffusion-free.
The following components are available:
Channel
Bend
Connection set
Connection frame
Sealing collar
The sealing collar is used to seal the air ducts on the heat pump.
The air ducts themselves are not screwed directly onto the heat
pump. When the system is installed ready for operation, only
the rubber seal comes into direct contact with the heat pump.
This guarantees easy assembly and disassembly of the heat
pump and also ensures that solid-borne noise is well insulated.

Connection of onsite air duct
If an alternative type of air duct is used to the one available as
an accessory, the external and internal dimensions as specified
in the drawing must be adhered to. Also ensure that the vibra-
tion and duct insulation are adequate.
If flange-mounted air ducts are used, connecting stubs are se-
cured on the air inlet and air outlet sides of the evaporator with
4 M8 x 16 hexagon bolts in the threaded holes provided. When
doing this, ensure that both air duct stubs touch only the insu-
lation. There should be no contact with the external sheeting.
