12. INTERVENTION WATER SAFETY
The electrical heater is equipped with a thermostat which also has safety function: it interrupts the power supply to the electric
heater in case of excessive water temperature. If this occurs, to start again the appliance, it is necessary a manual
intervention (manual reset).
DANGER: THE OPERATION OF THE THERMAL CUT-OUT INDICATES A POSSIBLY DANGEROUS
SITUATION. DO NOT RESET THE THERMAL CUT-OUT UNTIL THE WATER HEATER HAS BEEN
SERVICED BY A QUALIFIED PERSON
For the manual reset operation proceed as follows:
a) disconnect the power supply
b) remove the electrical resistance of the protective cover (FIG_12-1)
c) press reset button positioned on the thermostat (R - FIG_9-1)
d) mount of electrical resistance protective cover (FIG_12-1)
e) restore power supply
13. SAFETY VALVE INTERVENTION
The device is equipped with overpressure safety valve: it protects the tank from possible excessive pressure caused by the
expansion of water during heating. Upon the occurrence of this situation, the water is discharged through the outlet of which
is equipped with the valve.
A small amount of water may escape from this exhaust during the step of heating water.
CONTINUE A LOSS OF WATER FROM THE VALVE MAY INDICATE A PROBLEM WITH HEATING.
FAILURE TO OPERATE THE RELIEF VALVE EASING GEAR AT LEAST ONCE EVERY SIX MONTHS
MAY RESULT IN THE WATER HEATER EXPLODING. CONTINUOUS LEAKAGE OF WATER FROM THE
VALVE MAY INDICATE A PROBLEM WITH THE WATER HEATER
