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

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.
