⚠
DANGER TO LIFE!
Only authorized refrigeration technicians may work on the refriger-
ant circuit. (See the “References” section).
System modifications
Only authorized installers may carry out modifications on the following components:
• The heat pump unit
• The pipes for the refrigerant, brine, water and power
• The safety valve
You must not carry out construction installations that may affect the operational safety of the
heat pump.
Safety valve
The following safety precautions apply to the hot water circuit’s safety valve with correspond-
ing overflow pipe:
• Never block the connection to the safety valve’s overflow pipe.
• Water expands when it is heated, this means that a small amount of water is released
from the system via the overflow pipe. The water that exits the overflow pipe can be hot!
Therefore, allow it to flow to a floor drain where there is no risk of burning yourself.

Protection
Corrosion Protection
Due to the risk of corrosion, avoid using different types of sprays in the vicinity of the heat
pump. This particularly applies to:
• Solvents
• Chlorinated cleaning agents
