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 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. Both the heating system and the heat source must be
properly designed and dimensioned to ensure efficient operation.
It is particularly important to keep water flow temperatures as low
as possible. All connected energy consumers should therefore
be suitable for low flow temperatures. Raising the heating water
temperature by 1 K corresponds to an increase in energy con-
sumption of approx.
2.5 %. Low-temperature heating systems with flow temperatures
between 30 °C and 50 °C are particularly well-suited for energy-
efficient operation.
