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 do-
mestic 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.
4 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 with a lift
truck, hand truck or by means of 3/4" pipes fed through the holes
in the base plate or frame.
The heat pump and the transport pallet are joined by four transit
bolts. These must be removed.
Before using the transport holes in the frame, it is necessary to
remove the lower side panel assemblies. This is done by loosen-
ing each of the two screws at the base and then withdrawing the
panels by unhooking them from above. Rehang the panels by
gently pushing them in an upwards direction.
Be careful not to damage any components when inserting the
pipes through the frame.
At the installation location, 8 black dust caps, which are included
in the packaging of the device, must be snapped into the trans-
port holes.
