HPWH 300 - HPWH 300HE
5.2 Connecting the condensate
hose
The condensate hose is routed out through the sheet metal cov-
ering. It should be routed in such a way that the condensate pro-
duced (during heat pump operation) can flow away freely - en-
sure frost-free drainage.
There is a pressureless seal valve at the end of the condensate
hose, which must be relocated accordingly if the condensate
hose is shortened (the valve can be easily removed and re-in-
serted).

5.3 Electrical connection

The domestic hot water heat pump is wired ready for use; power
is supplied via the mains power connection, which is plugged into
an earthed wall socket (~230 V, 50 Hz). This socket must remain
accessible after installation.
The installation (electical work) and commissioning, as well as
the maintenance of this equipment, must only be carried out by
an authorised qualified contractor in accordance with these in-
structions.
Mains power connection replacement
The electrical connecting terminal (X2) is located on the partition
in the device.
 Cable type: H07RN-F3G 1.5 mm²
 Routing in accordance with the original mains power con-
nection via cable entry on the rear wall.
 Sheath stripping length 85 mm
 Shorten L/N wires to 55 mm
 Strip wires 7 mm, fit with cable ferrules and connect to X2: L/
N/PE
If the supply cord is damaged, it must be replaced by a special
cord or assembly available for the manufacturer or its service
agent.

6.1 Domestic hot water system

ATTENTION!
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.
Commissioning the domestic hot water system
 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.
 Purge the domestic hot water circuit (open domestic hot
water taps at the highest extraction points until there are no
more traces of air).
 Check the entire domestic hot water system for leaks.
 Establish the power supply.
6.2 Operating the domestic hot
water heat pump
Apart from the switch for the electric heating element, there are
no other controls on the device. The domestic hot water temper-
ature is preset to 60°C and is regulated automatically.
