Set-UP

5.1 General Information

The unit must be installed indoors on a level, smooth and hori-
zontal surface. The entire base of the frame should lie directly on
the floor to ensure a good soundproof seal. If this is not the case,
additional sound insulation measures may be necessary. If the
device is installed on top of a built-under buffer tank, a surface
that fully supports the base is required. The heat pump must be
installed so that maintenance work can be carried out without
being hindered. This can be ensured by maintaining a clearance
of 1 m in front and to the left and right of the heat pump.
Never install the device in rooms subject to high humidity. Con-
densation can form on the heat pump and air circuit if the humid-
ity exceeds 50% and the external temperature is below O °C.
If the heat pump is installed on an upper storey, the load-bearing
capacity of the ceiling should be checked. On account of the
acoustics, measures for isolating possible vibrations should also
be very carefully planned in advance as well. Installation on a
wooden floor is not recommended.

5.2 Condensed Water Pipe

Condensed water that forms during operation must be drained
off frost-free. The heat pump must be mounted on a level plane
to guarantee proper drainage. The condensed water pipe must
have a minimum diameter of 50 mm and should be fed frost-free
into a sewer. Condensate should not be discharged directly into
clearing tanks and cesspits because the aggressive vapours
could destroy the evaporator.

5.3 Sound

To prevent solid-borne sound from being transmitted to the
heating system, we recommend connecting the heat pump
to the heating system using a flexible hose.
Installed air ducts should be sound-isolated from the heat
pump to prevent the transmission of solid-borne sound to
the ducts.
If the transport restraint screws are not removed from the
compressor, acoustic emissions from the device are signifi-
cantly louder!

Installation

6.1 General Information
The following connections need to be established on the heat
pump:
- Fresh and exhaust air
- Flow and return flow of the heating system
- Condensate outflow
- Power supply
- Removing the accessory pack from the heat pump

6.2 Air Connection

ATTENTION!
Do not restrict or block the area around the air intake or outlet.
ATTENTION!
Only operate the heat pump with the air ducts connected.
The glass fibre reinforced concrete air ducts offered as accesso-
ries are moisture-resistant and diffusion-free (exhaust air duct
600 x 600 and inlet duct 750 x 750). When using the air duct for
the air outlet side (600 x 600), the "insulating mat duct connec-
tion" (in the accessory pack) is to be adhered to the air outlet on
the desired connection side.
The sealing collar is used to seal the air ducts on the heat pump.
The air ducts are not screwed directly onto the heat pump. Only
the rubber seal comes into direct contact with the heat pump
when the system is installed correctly. This guarantees easy as-
sembly and disassembly of the heat pump and also ensures that
solid-borne sound is well insulated.
If an alternative air duct is being used to that which has been sup-
plied as an accessory, care must be taken to ensure that it does
not reduce the cross sectional area of the air intake and air outlet
sides. The "small and large sealing rings" included in the scope
of supply can be used for sealing the heat pump connection.
They also function as vibration isolators.
The large sealing ring can be used to position the air intake open-
ing of the heat pump directly onto an appropriately constructed
wall opening. The minimum distance between the device and the
wall is 100 mm.
