3.2 Switch box
The switch box is located in the heat pump. It can be swung out
after removing the lower front cover and loosening the fastening
screw located in the upper right-hand corner.
The switch box contains the supply connection terminals as well
the power contactors and the soft starter unit.
The plug connector for the control line is located on the base of
the device adjacent to the cable gland in the base plate.
3.3 Heat pump controller
Use the heat pump controller included in the scope of supply to
operate the air-to-water heat pump.
The heat pump controller is a convenient electronic regulation
and control device. It controls and monitors the entire heating
system on the basis of the external temperature, including dome-
stic hot water preparation and safety systems.
The customer must install the return temperature sensor and the
external temperature sensor, which are supplied with the heat
pump controller / with these instructions together with the neces-
sary fixing accessories.
The enclosed operating instructions describe the function and
use of the heat pump controller.

Transport
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 either
with a lift truck or a crane. The transport eyebolts must be remo-
ved after crane transport and the sheet metal openings closed
with the closing plugs supplied.
After the transport, the transport securing device is to be re-
moved on either side at the bottom of the unit.
ATTENTION!
The transport securing device is to be removed prior to commissioning.

5.1 General
The device should always be installed on a permanently smooth,
even and horizontal surface. The entire frame should lie directly
on the ground to ensure a good soundproof seal and to prevent
the water-bearing components from becoming too cold. If this is
not the case, additional insulation measures may be necessary.
Furthermore, the heat pump should be set up so that the air out-
let direction of the ventilator is perpendicular to the main wind di-
rection to allow unrestricted defrosting of the evaporator. It must
be possible to carry out maintenance work without hindrance.
This is ensured when observing the distances to solid walls as
shown in the figure.
Cleaning the condensate tray without dismantling the ventilator is
only possible if a distance of 0.4 m is observed on one side of the
heat pump.
Do not restrict or block up the area around the air inlet or outlet.
5.2 Condensed Water Pipe
Condensed water that forms during operation must be drained
off frost-free. To ensure proper drainage, the heat pump must be
mounted horizontally. The condensed water pipe must have a
minimum diameter of 50 mm and should be fed frost-free into a
sewer. Condensed water should not be discharged directly into
clearing tanks and cesspits because the aggressive vapours
could destroy the evaporator.
