11.4 Cleaning and maintenance of the cylinder
Replacement
Important: the cylinder must be only be replaced by qualied
personnel, and with the humidier disconnected 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 (cylinder replacement procedure, see maintenance 1.
menu);
turn o the humidier (switch “0”), and open the mains disconnect
2.
switch on the power supply (safety procedure);
wait for the humidier and the cylinder to cool down;3.
remove the front cover;4.
disconnect the electrical cables from the cylinder;5.
release the cylinder from the locking device and lift it to remove it;6.
insert the new cylinder (make sure that the model and the power supply 7.
of the new cylinder correspond to the rated data);
fasten the cylinder; 8.
reconnect the electrical cables to the cylinder;9.
replace the front cover;10.
switch on the humidier;11.
reset cylinder operating hour counter (see maintenance menu);12.
Activate the wash new cylinder procedure (see maintenance menu).13.
11.5 Mechanically draining the water in the
cylinder
Drain due to gravity without activating the humidier, recommended if:
humidier decommissioned;•
to empty the cylinder without switching the humidier on.•
Mechanical drain:
make sure that the humidier is not powered;•
remove the cover (see page• 8);
activate the mechanical device under the cylinder (see the gure below).•

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.
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.
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.
