9 Maintenance and
cleaning
WARNING!
Any equipment repair must be performed by
qualified personnel. Improper repairs can put
the user in serious danger. If your equipment
needs to be repaired, 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. Therefore, 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.
In order to reset the protection it is necessary to:
Disconnect the device from the mains power
supply;
Remove any air ducts (see paragraph 6.1.1);
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 the 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 can 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 the 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.
9.2
Quarterly inspections
Visual inspection of the general conditions of the
equipment systems as well as the absence of
leaks;
Inspection of the ventilation filter
(see paragraph 9.4).
9.3
Annual inspections
Inspection of the tightness of bolts, nuts, flanges
and water supply connections that may have been
loosened by vibration;
Check the state of integrity of the magnesium
anodes (see paragraph 9.5).
