4.9.4. Water supply system
Before filling or any subsequent refilling of the system, make sure to check the quality of the water in the heating
system:
• Visually check the water for precipitation of other materials. If this occurs, the user is required
to clean the system.
• Use only demineralized heating water or water that complies with the VDI 2035 standard. Fail-
ure to do so may result in a decrease in the efficiency of the device and even damage to its
components.
Desliming of the system is not included in the installation and commissioning of the heat pump.
• Check with a magnetic rod whether magnetite (iron oxide) is present in the water. If found, treat
the water accordingly.
In the case of an existing installation, clean the system and install a magnetic filter.
• Check the pH value of the water at a temperature of 25°C.
It is generally accepted that water should be treated if the values in Table 16 are not met.

Tab. 16. Recommended water hardness values
Improper additives can cause the risk of material damage and harmful physical changes in parts. This can be
especially true for seals of all kinds. For this reason, antifreeze, corrosion inhibitors and sealants should not be
used. The technical parameters of the installation water should be checked at the annual technical inspection of
the heat pump and corrected as necessary to the required values.
