Quarterly inspections

Visual inspection of the general conditions of
the equipment systems as well as the absence
of leaks;
Inspection of the ventilation .
4.4

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 .

Cleaning of the ventilation filter

For the mod. 160-200-260
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. 7).
The filter can be cleaned with rinsing, water gush
or slamming. Since the filter is made of stainless
steel, it does not need to be periodically
substituted.

N.B.: The filter obstruction reduces the

causing insufficient, or, even total lack
of ventilation.

Magnesium anodes

The magnesium anode
"sacrificial" anode, avoids any parasitic currents
that are generated inside the boiler that can
trigger corrosion processes on the device surface.
In fact, magnesium is a metal with a lower
electrochemical potential when compared to the
material that lines the inside of the boiler, therefore
it first attracts the negative charges that form with
the heating of the water and that cause it to
corrode. Therefore, the anode "sacrifices" itself by
corroding instead of the tank. The boiler has two
anodes, one that has been mounted in the lower
part and another in the upper part of the tank (the
area that is most subject to corrosion).
The integrity of the magnesium anodes must be
checked at least every two years (even better if
checked on an annual basis). The operation must
be carried out by qualified personnel.
Before performing the inspection, it is necessary to:
Close the cold water input supply;
Empty the water
paragraph 8.5);
Unscrew the upper anode and check its state
of corrosion, if more than 30% of the anode
surface is corroded then it is necessary to
replace it;
Carry out the same operation for the lower
anode.
The anodes have appropriate sealing gaskets, in
order to avoid causing
recommended to use anaerobic sealant for
threads compatible for use on sanitary and
heating systems. The gaskets must be substituted
both in case of inspection as well as the
replacement of anodes with new gaskets.
For the mod. 90
To carry out the verification of the replaceable
anode it is necessary to drain the water from inside
the boiler (see paragraph 4.6).
For the verification or substitution of the sacrificial
anode, remove the lower panel (Fig. 5)
After having removed the lower panel, disconnect
the four electrical connectors of the electronic
control unit. Once removed the panel, unscrew
counterclockwise the anode using an appropriate
instrument and remove the old sealing gasket (Fig.
8).
Verify the integrity level of the component. In case
there are evident, considerable corrosion marks
that could jeopardize its use (reduction of the
system performance
