1.1 Important information:

ATTENTION!
The heat pump is not secured to the wooden pallet.
ATTENTION!
The heat pump must not be tilted more than 45° (in any direction).
ATTENTION!
Do not use the holes in the panel assemblies for lifting the device!
ATTENTION!
Flush the heating system prior to connecting the heat pump.
ATTENTION!
The supplied dirt trap must be inserted in the heat source inlet of the heat
pump to protect the evaporator against the ingress of impurities.
ATTENTION!
The brine solution must contain at least a 25 % concentration of a
monoethylene glycol or propylene glycol-based antifreeze, which must
be mixed before filling.
ATTENTION!
The heat pump must be started up in accordance with the installation and
operating instructions of the heat pump controller.
ATTENTION!
The supplied dirt trap must be inserted in the heat source inlet of the heat
pump to protect the evaporator against the ingress of impurities.
ATTENTION!
Any work on the heat pump may only be performed by authorised and
qualified after-sales service technicians.
ATTENTION!
Disconnect all electrical circuits from the power source prior to opening
the device.

1.2 Legal Regulations and
Directives
This heat pump conforms to all relevant DIN/VDE regulations
and EU directives. Refer to the EC Declaration of Conformity in
the appendix for details.
The heat pump must be connected to the power supply in com-
pliance with all relevant VDE, EN and IEC standards. Any further
connection requirements stipulated by local utility companies
must also 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.
1.3 Energy-Efficient Use of the
Heat Pump
By operating this heat pump you are helping to protect our envi-
ronment. The heating or cooling system and the heat source
must be properly designed and dimensioned to ensure efficient
operation. It is particularly important to keep water flow tempera-
tures as low as possible in heating operation. All connected en-
ergy consumers should therefore be suitable for low flow temper-
atures. Raising the heating water temperature by 1 K
corresponds to an increase in energy consumption of approx.
2.5 %. Low-temperature heating systems with flow temperatures
between 30 °C and 50 °C are well-suited for energy-efficient op-
eration.
