DANGER! Only authorized refrigeration technicians may work
on the refrigerant circuit.
2.2 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
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.
