WARNING!
Any equipment repair must be performed by
qualified personnel. Improper repairs can
put the user in serious danger. If your
equipment requires repair, please contact
the technical assistance service.
WARNING!
Before attempting any maintenance operation,
make sure that the equipment is not and
cannot be accidentally connected to the
power supply: disconnect the equipment
from the mains power supply before
carrying out any maintenance or cleaning
activities.
9.1 Resetting of safety equipment
The device is equipped with a safety thermostat. When
manually reset, the equipment is tripped in case of
over-heating.
To reset the protection it is necessary to:
•
Disconnect the device from the mains power
supply;
•
Remove any air ducts (see paragraph 0);
•
Remove the upper cover by undoing the
appropriate locking screws (Fig. 18);
•
Manually reset the tripped safety thermostat from
the top (Fig. 19). In the event of tripping, the
central pin of the thermostat sticks out by
approximately 4 mm;
•
Reassemble the upper cover that was previously
removed.

WARNING!
The tripping of the safety thermostat may be
caused by a fault linked to the control
board or by the absence of water inside
the tank.
WARNING!
Carrying out repair operations on parts that
perform safety functions jeopardises safe
operation of the equipment. Substitute the
faulty elements only with original spare
parts.
N.B.
The intervention of the thermostat excludes
the operation of the electric heating
elements but not the heat pump system
within the permitted operating limits.
