Set-UP

6.1 General Information

The air-to-water heat pump must be installed in a frost-free, dry
room on an even, smooth and horizontal surface. The entire
base of the frame should lie directly on the floor to ensure an
ad-equate 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 hin-
dered. This is ensured if the clearance displayed below is main-
tained.
0,6 m
Never install the device in rooms subject to high humidity. Con-
densation can form on the heat pump and air circuit if the hu-
midity exceeds 50% and the external temperature is below
0 °C.
Neither frost nor temperatures higher than 35 °C must occur in
the installation location at any time of the year.
If the heat pump is installed on an upper storey, the load-bear-
ing 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.

6.2 Condensed Water Pipe

Condensate that forms during operation must be drained off
frost-free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensate pipe must have a mini-
mum diameter of 50 mm and must be fed into a sewer in such
a way that it is safe from frost. Do not discharge the condensate
directly into clearing tanks or cesspits, as aggressive vapours or
a condensed water pipe which has not been laid in a frost-free
manner could destroy the evaporator.

6.3 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.

pump:
Fresh and exhaust air

Flow and return of the heating system

 Condensate outflow
Temperature sensor

 Voltage supply

7.2 Air connection

7.2.1 Air Connection General Information
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
accessories are moisture-resistant and diffusion-free.
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 sound is well insulated.
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
vibration and duct insulation are adequate.
If flange-mounted air ducts are used, connecting stubs are
secured 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
insulation. There should be no contact with the external
sheeting.
