8.3 Cleaning and maintenance of the cylinder
Replacement
Important: the cylinder must be only be replaced by quali ed
personnel, and with the humidi er unplugged from the power
supply.
In normal conditions, the disposable cylinders should be replaced after
one year (or 2500 hours of operation, if cleaned periodically), while the
openable cylinders last 5 years (or 10,000 hours of operation, if cleaned
periodically). They must be replaced immediately – even before the
speci ed intervals – if any anomalies occur. For example, when the lime
scale inside the cylinder prevents the correct  ow of electric current.
Replacement procedure:
empty all the water (see par. “7.15” page 27);
turn o the humidi er (switch “0”), and open the mains disconnect
switch on the power supply (safety procedure);
wait for the humidi er and the cylinder to cool down;
remove the front cover (see par. “1.6” page 8);
disconnect the electrical cables from the top of the cylinder;
release the cylinder from its fastening device and lift it up to remove
it;
insert the new cylinder (make sure that the model and the power
supply of the new cylinder correspond to the rated data);
fasten the cylinder;
reconnect the electrical cables to the top of the cylinder;
replace the front cover;
switch on the humidi er.
Periodical checks
After one hour of operation: check for any signi cant water leaks.
Every 15 days or no more than 300 operating hours: check operation,
the absence of signi cant water leaks, the general conditions of
the casing. Check that during operation there are no arcs or sparks
between the electrodes.
Every 3 months or no more than 1000 operating hours:
disposable cylinders: check operation, the absence of signi cant
water leaks and if necessary replace the cylinder;
openable cylinders: if there are signi cantly blackened areas, check
the deposits on the electrodes and clean them, using the speci c
electrode and gasket kit (see Tab. 8.c).
Every year or no more than 2500 operating hours:
disposable cylinders: replace;
openable cylinders: if there are signi cantly blackened areas, check
the deposits on the electrodes and clean them, using the speci c
electrode and gasket kit (see Tab. 8.c).
After 5 years or no more than 10,000 operating hours: replace the
openable cylinder.
After extended operation, or when using water rich in salts, the solid
deposits that naturally form on the electrodes may grow until attaching
to the inside wall of the cylinder. If these deposits are conductive the heat
generated may overheat the plastic until it melts, with the risk of very hot
water being released.
Important: In the event of water leaks, disconnect the power
supply from the humidi er as the water may conduct electricity.

8.5 Cleaning and maintenance of the other
components
Important:
when cleaning the plastic components do not use detergents or
solvents;
scale can be removed using a solution of 20% acetic acid and then
rinsing with water.
Maintenance checks on other components:
 ll solenoid valve (Fig. 8.a part. 3 and Fig. 8.c part. 2). After having
disconnected the cables and the tubing, remove the solenoid valve
and make sure the inlet  lter is clean; if necessary, clean with water
and a soft brush;
manifold with drain pump (Fig. 8.a part. 5). Check that there are no
solid residues in the cylinder attachment, remove any impurities.
Check that the gasket (o-ring) is not damaged or cracked, replace if
necessary. Check that there are no solid residues in the drain hose;
drain pump (Fig. 8.c part. 4). Disconnect the power supply, unscrew
the fastening screws and remove any impurities (Fig. 8.a part. 6). Clean
the tank from any deposits and check that the water  ows freely from
the tank to the drain (corresponding to the drain pump);
tank (Fig. 8.a part. 1). Check that there are no obstructions or solid
particles and that the conductivity measuring electrodes are clean,
remove any impurities and rinse;
internal pipe kit (Fig. 8.a part. 2 and Fig. 8.c part. 3). Check that the
pipes and hoses are free and clear of impurities, remove any impurities
and rinse.
Important: after having replaced or checked the water circuit,
make sure that the connections are tight. Restart the unit and run
a number of  ll and drain cycles (from 2 to 4), after which, applying the
safety procedure, check for any water leaks.
