2.3 System modifications
Only qualified installers may carry out modifications on the following components:
▪
The heat pump unit
▪
The pipes for the refrigerant, brine and water
▪
The power supply
▪
The safety valves
Do not carry out construction installations that may affect the operational safety of the heat pump.
2.4 Safety valves
▪
Never block the connection to a safety valve’s overflow pipe.
▪
The following safety precautions apply to the hot water circuit’s safety valve with corresponding over-
flow pipe: Water expands when it is heated, which 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 to prevent any risk of burning yourself.
