The ingress of oxygen into the heating water circuit may result in the formation of oxidation products (rust), particu-
larly if steel components are used. This oxygen enters the heating system via the valves, the circulating pumps and/or
plastic pipes. It is therefore essential - in particular with respect to the piping of underfl oor heating systems - that only
diffusion-proof materials are used.
ATTENTION!
We recommend the installation of a suitable corrosion protection system to prevent the
formation of deposits (e.g. rust) in the condenser of the heat pump.
The heat pump is started up via the heat pump controller.
ATTENTION!
The heat pump must be started up in accordance with the installation and operating instructions of the heat
pump controller.
If an overfl ow valve is fi tted to assure the minimum heating water fl ow rate, the valve must be set in accordance with
the requirements of the respective heating system. Incorrect adjustment can lead to faulty operation and increased
energy consumption. We recommend carrying out the following procedure to correctly adjust the overfl ow valve:
Close all of the heating circuits that may also be closed during operation (depending on the type of heat pump us-
age) so that the most unfavourable operating state - with respect to the water fl ow rate - is achieved. This normally
means the heating circuits of the rooms on the south and west sides of the building. At least one heating circuit must
remain open (e.g. bathroom).
The overfl ow valve should be opened far enough to produce the maximum temperature spread between the heating
fl ow and return fl ow listed in the table below for the current heat source temperature. The temperature spread should
be measured as close as possible to the heat pump. The heating element of mono energy systems should be discon-
nected.

Any faults occurring during operation are displayed on the heat pump controller and can be corrected as described
in the operating manual of the heat pump controller.
The heat pump is maintenance-free. To prevent faults due to sediment in the heat exchangers, care must be taken
to ensure that no impurities can enter either the heat source system or the heating system. In the event that operating
malfunctions due to contamination occur nevertheless, the system should be cleaned as described below.
ATTENTION!
Remove the transportation screw before starting the heat pump (see pic. 5.1).
