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 hindered.
This is ensured if the clearance displayed below is maintained.
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 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-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.
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 di-
rectly 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 heat-
ing 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.

Installation
7.1 General
The following connections need to be established on the heat
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.
