2.2 System modifications
Only authorized installers may carry out modifications on the following
components:
•
The heat pump unit
•
Water and electrical installations
•
The safety valve
Do not carry out construction installations that may affect the opera‐
tional safety of the heat pump.
2.3 Safety valve
The following safety precautions apply to the hot water circuit’s safety
valve with corresponding 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.
