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.

Persons, especially children, who are not capable of operating
the device safely due to their physical, sensory or mental abilities
or their inexperience or lack of knowledge, must not operate this
device without supervision or instruction by the person in charge.

Children must be supervised to ensure that they do not play with
the device.

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.
