Working conditions
Defrosting
In heating mode the unit will defrost automatically, maximizing the heating efficiency (Lasting 2 -
10 minutes).
The fan motor will stop running whilst the unit is defrosting.
Overheating protection
When the water temperature reaches 75deg C, the power of the unit will be cut and must be
manually reset. See page __ for more information.
Water pressure protectiontemperature or
A P&T valve MUST be installed in the tank. When the tank pressure reaches 0.85MPa or
when the tank temperature reaches 93deg C, the P&T valve will open automatically so as
to reduce the pressure or temperature decrease.
