16.6 - Cleaning of air intake filter
The air filter must be cleaned in order for the appliance to
work correctly. Refer to Figure 16-8 and proceed as follows:
1. - access the appliance’s internal parts by following the
procedure described in section 16.2;
2. - pull out filter detail “A” as shown in the figure;
3.- clean the filter with compressed air until its surface is
clean again;
4.- reassemble the filter and the appliance’s casing.
16.7 - Maintenance and cleaning of
condensate outlet system
During appliance maintenance the condensate outlet pipe
(detail “5” in figures 3-3, 3-5 and 3-7) is taken apart and cleaned
of any residues. Reassemble the cleaned pipe and
restore the level of liquid in the siphon as shown in section
14.1.2.
Check the level of pH every three months for the first year.
Special litmus papers or a special electronic instrument that
gives a more precise reading can be used to carry out the test
(access the box via stopper “E” in figure 10-1). The frequency
of these checks can then be reduced to every six months
or year depending on how they are controlled by the local
regulations in force. The neutralising contents of the box must
be replaced when the level of pH falls below the level required
by the regulations in force. The permitted acidity level goes
from pH 5.5 to 9.5.
To replace the neutralising agent, do the following:
1. Follow the steps of section 16.2 to take off cover “E” in
figure 16-1;
2. Remove box “A” (Figure 16-9);
WARNING! When the box is taken out, be careful
to hold it at an angle so as to prevent any leaks of liquid
that might cause damage.
3. Open cover “C” (Figure 16-9) upwards;
4. Check the good order of the box;
5. Check the good order of the neutralising material and if
necessary add some or replace it;
6. Fill with fresh water until the water begins to flow out of
the outlet;
7. Replace the box in the correct position;
WARNING! The neutralisation box is filled with
water to prevent exhaust gas from escaping while the
unit is in operation.
8. Turn on the gas supply;
9. Restore the appliance’s electric power supply;
WARNING! Carefully follow figure 16-9 to replace
the box “A” in the correct position. After the maintenance
described above, restore the level of liquid in the siphon
as shown in section 14.1.2.
