4.2 Safety thermal devices

The appliance is equipped with a (manually reset) safety thermostat, to protect against excessive and
hazardous overheating which might accidentally occur inside it. If the safety thermostat is activated, the
power supply to the appliance is cut off.
The safety thermostat is located at the back (bottom) of the appliance (see the attached "Technical Data
Sheet"); to reset it after it has tripped, unscrew the protective cap using an appropriate tool and press the
"reset" button all the way. Replace the protective cap so that it cannot be unscrewed without the use of a
tool.
Important
Safety thermostat should only be reactivated after eliminating the anomaly that caused them to trip. This
can only be done by a Service technician.
