9.3 Cleaning and maintenance of the cylinder
Replacement
Important: he cylinder must be only be replaced by qualifi ed
personnel, and with the humidifi 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 specifi ed
intervals – if any anomalies occur. For example, when the lime scale inside
the cylinder prevents the correct fl ow of electric current.
Replacement procedure::
1. empty all the water (see chap. 6);
2. turn off the humidifi er (switch “0”), and open the mains disconnect
switch on the power supply (safety procedure);
3. wait for the humidifi er and the cylinder to cool down;
4. remove the front cover;
5. disconnect the electrical cables from the cylinder;
6. release the cylinder from the locking device and lift it to remove it;
7. insert the new cylinder (make sure that the model and the power supply
of the new cylinder correspond to the rated data);
8. fasten the cylinder;
9. reconnect the electrical cables to the cylinder;
10. replace the front cover;
11. switch on the humidifi er;
12. reset cylinder operating hour counter (see parameters da , chap. 7);
13. Activate the wash new cylinder procedure, pressing ENTER + DOWN for
5 seconds
9.4 Mechanically draining the water in the
cylinder
Drain due to gravity without activating the humidifi er, recommended if:
• humidifi er decommissioned;
• to empty the cylinder without switching the humidifi er on.
Mechanical drain:
• make sure that the humidifi er is not powered;
• remove the cover;
• activate the mechanical device under the cylinder (see part A, Fig. 9.e).

Periodical checks
• After one hour of operation: check for any signifi cant water leaks.
• Every 15 days or no more than 300 operating hours: check operation, the
absence of signifi 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 signifi cant water
leaks and if necessary replace the cylinder;
- openable cylinders: if there are signifi cantly blackened areas, check the
deposits on the electrodes and clean them, using the specifi c electrode
and gasket kit.
• Every year or no more than 2500 operating hours:
- disposable cylinders: replace;
- openable cylinders: if there are signifi cantly blackened areas, check the
deposits on the electrodes and clean them, using the specifi 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 humidifi er as the water may conduct electricity.
