4.2 Safety thermal device

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 trips, 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
The safety thermostat should only be reactivated after eliminating the functional anomalies that caused it
to trip. This can only be done by a Service technician.
