supply;
•
Remove any air ducts (see paragraph 5.2);
•
Remove the upper cover by undoing the
appropriate locking screws (Fig. 17);

8.2 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
8.4).

8.3 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 8.5).

8.4 Cleaning of the ventilation filter

In the upper part of the equipment there is a ventilation
filter. This must be periodically cleaned in order to
maintain the perfect efficiency of the system.
After every 1000 hours of operation, the display of the
equipment shows the "FiL" alarm that indicates the need
to check the cleanliness of the filter.
To remove the filter, it is necessary to grab it with the
fingers from the dedicated side opening and pull it outside
(Fig. 19).
