1.1Important Information
ATTENTION!
Any work on the heat pump may only be performed by an authorised and qualified customer service.
ATTENTION!
The heat pump must not be tilted more than max. 45° (in either direction).
ATTENTION!
The transport securing devices must be removed prior to commissioning.
1.2Legal Provisions and
Guidelines
This heat pump conforms to all relevant DIN/VDE regulations and EU directives. For details refer to the EC Declaration of Con- formity in the appendix.
The electrical connection of the heat pump must be performed according to and conforming with all relevant VDE, EN and IEC standards. Beyond that, the connection requirements of the local utility companies have to be observed.
The heat pump is to be connected to the heat source system and the heating or cooling system in accordance with all applicable regulations.

ATTENTION!
The supplied strainer must be fitted in the heating water inlet of the heat pump in order to protect the condenser against the ingress of impurities.
ATTENTION!
The supplied strainer must be fitted in the heat source inlet of the heat pump in order to protect the evaporator against the ingress of impurities.
ATTENTION!
The brine solution must contain at least 25 % of an antifreeze agent on a
ATTENTION!
The clockwise phase sequence must be observed when connecting the load lines (the heat pump will deliver no output and will be very noisy when the phase sequence is incorrect).
ATTENTION!
Commissioning is to be effected in accordance with the installation and operating manual of the heat pump controller.
ATTENTION!
To prevent the accumulation of deposits (e.g. rust) we recommend using a suitable corrosion protection system.
ATTENTION!
Disconnect all electrical circuits from the power supply before opening the enclosure.
1.3Energy-Efficient Use of the
Heat Pump
By operating this heat pump you contribute to the protection of our environment. The heating or cooling system and the heat source must be properly designed and dimensioned to ensure ef- ficient operation. In particular, it is important to keep water flow temperatures as low as possible. All energy consumers con- nected should therefore be suitable for low flow temperatures. A 1 K higher heating water temperature corresponds to an increase in power consumption of approx. 2.5 %.
