The domestic hot water heat pump must only be operated when filled with
water.
Domestic hot water system requirements
The following materials can be used in the consumer's domestic
hot water system:
 Copper
Stainless steel

 Brass
 Plastic
Depending on the materials used in the domestic hot water sys-
tem (customer installation), material incompatibility may lead to
corrosion damage. This especially applies to zinc-plated materi-
als and materials containing aluminium. If there is a risk of water
contamination during operation, it may be necessary to install a
filter.

 All installations for the water circuit and air circuit, as well as
all electrical installations, must have been carried out cor-
rectly and fully completed.
 Fill the domestic hot water circuit via an external connection.

water taps at the highest extraction points until there are no
more traces of air).
 Check the entire domestic hot water system for leaks.
