Storage and Transport

The heat pump should generally be stored and transported pack-
aged in an upright position. If handled carefully, the device can
be transported over short distances with a max. tilt angle of 45°.
Ambient temperatures between -20 and +60 °C are permissible
during transport and storage.
ATTENTION!
When transporting the heat pump, ensure that it is not tilted more than
45° (in any direction).
Use a wooden pallet for transporting the heat pump to the final in-
stallation location. The basic device can be transported with a lift
truck, hand truck or by means of 3/4" pipes fed through the holes
in the base plate or frame.
Take care that the max. tilted position of 45° is not exceeded. If
the heat pump can only be transported in a tilted position, the
heat pump (heat pump switch) should not be operated for at least
one hour after installation in its final location.

Set-Up

The heat pump must be installed in a frost-free and dry room.
Both the room temperature and the air drawn in by the heat pump
should be within a temperature range of 0 °C to 40 °C (required
for heat pump operation).
ATTENTION!
In addition, the heat pumpmust not be set up in rooms which are subject
to explosion hazards through gasses, vapours or dust; furthermore,
adequate and unobstructed air supply and discharge must be ensured for
the setup location. (Allow for sufficient space for air hoses)
Good thermal insulation from the neighbouring rooms is recom-
mended. (Due to cooling of the set-up room if the extracted air is
directed into this room.)
Condensate drainage (with a siphon) must be provided.
The set-up surface must be plane, smooth and level so that the
device frame rests on it all the way around. Additional sound-in-
sulating measures are recommended if this is not the case. The
set-up surface should have sufficient strength and reduce vibra-
tion, if possible.
To ensure troublefree operation and to enable access for main-
tenance and repair work, minimum distances of 0.6 m around the
device are recommended when setting up the heat pump. The
minimum distance between the air intake connection side and
the wall is 0.3 m (refer also to section 5.1).

5.1 General

Depending on the use of the heat pump (as hot water heat pump
or heating heat pump), different types of pipes must be provided
at the installation site. Refer also to the integration diagrams in
the appendix. The heat pump can be installed against the wall or
in a corner.

5.2 Heating system connection

The use of copper, brass, stainless steel or plastic materials for
the pipe connection to the heat pump is recommended for the in-
stallation site. Material incompatibilities may cause corrosion
damage to the heating system if using galvanised or aluminium-
containing materials.
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. The heating water connec-
tions on the heat pump are designed as G1/2" flat gasket exter-
nal threads. To achieve leak-tightness, a relative low tightening
torque for the cap nut of the threaded heating connections is suf-
ficient.
The heating system must be flushed before making the connec-
tions for the heating water to remove potential contaminations.
The heating installation (when using the heat pump for heating
purposes) must ensure the minimum water flow rate (e.g.
through a correctly adjusted overflow valve in a heating bypass).
The heating system must be equipped with drain valves that can be used
to drain the heating water in case of impending frost (e.g. in case of power
failure or decommissioning).

5.3 Electrical Connection

Before making the electrical connection for the heat pump, the
external heat circulating pump must be hooked up and the heat-
ing system hydraulically filled and connected to the heat pump.
The heat pump is wired ready for use; power is supplied via
mains connection cables plugged into an earthed wall socket
(230 VAC, 50 Hz). Access to the outlet must be possible also
after the complete installation of the device.
To make the electrical connection to the external heat circulating
pump (M3), remove the front wall of the device (loosen the two
lower mounting screws and fold up the front wall of the device),
then fold down the switch box (loosen the two M5 screws on the
top of the switch box for this purpose). Guide the supply line (min.
3 x 0.75 mm²) of "M3" through the cable gland in the right side
wall and provide strain relief; make the connection to X1[2/N/PE].
(Refer also to the circuit diagram on the inside of the front wall of
the device or in the appendix of these instructions).
Optionally, an external heating element with max. 2 kW can be
selected via a properly dimensioned cable on X1[1/N/PE]. (An
