DANGER: RISK OF BURNING/SCALDING
WARNING
▪
When carrying out an inspection on the switch box of the unit, ALWAYS make
sure that the unit is disconnected from the mains. Turn off the respective circuit
breaker.
▪
When a safety device was activated, stop the unit and find out why the safety
device was activated before resetting it. NEVER shunt safety devices or change
their values to a value other than the factory default setting. If you are unable to
find the cause of the problem, call your dealer.
WARNING
Prevent hazards due to inadvertent resetting of the thermal cut-out: power to this
appliance MUST NOT be supplied through an external switching device, such as a
timer, or connected to a circuit that is regularly turned ON and OFF by the utility.
WARNING
Air purging heat emitters or collectors. Before you purge air from heat emitters or
collectors, check if or is displayed on the home screen of the user interface.
▪
If not, you can purge air immediately.
▪
If yes, make sure that the room where you want to purge air is sufficiently
ventilated.
Reason: Refrigerant might leak into the water circuit, and
subsequently into the room when you purge air from the heat emitters or
collectors.
