8.1 Power board fuse replacement

Proceed as indicated below (reserved for qualified technical
personnel only):
• Disconnect the power to the equipment.
• Remove the bottom cover.
• Remove the fuse cap, then the fuse, using a suitable screw-
driver.
• Install a new IEC 60127-2/II (T5AL250V) certified time-delay
5 A 250V fuse, then refit the protective cap.
• Reassemble all the plastics and make sure the equipment is
correctly installed before powering it.

8.2 Heating element safety thermostat reset

This equipment has a manual-reset safety thermostat connect-
ed in series with the heating element immersed in water, which
interrupts the power supply in case of overtemperature inside
the tank.
If necessary, proceed as follows to reset the thermostat (re-
served for qualified technical personnel):
• Unplug the product.
• Remove the bottom cover by first undoing the locking screws
(fig. 40).
• Manually reset the tripped safety thermostat (fig. 41). In case
of tripping, the central pin of the thermostat comes out by
fig. 40
cod. 3541T580 - Rev. 03 - 05/2020
about 2 mm.
• Refit the previously removed bottom cover.

Any maintenance operation must be carried out by quali-
fied personnel according that prescribed in the chapter
10 of this manual.
ATTENTION!: Intervention of the safety thermo-
stat can be caused by a fault linked to the control
board or by no water inside the tank.
ATTENTION!: Carrying out repair work on parts
with safety function compromises safe opera-
tion of the equipment. Replace faulty parts with
original spare parts only.
NB!: Intervention of the thermostat excludes operation of
the heating element but not the heat pump system within
the permitted operating limits.
ATTENTION! If the operator is unable to elimi-
nate the fault, switch off the equipment and con-
tact the Technical Assistance Service, communi-
cating the model of the product purchased.
