ENG
-
disposable cylinders: check operation, the absence of significant
water leaks and if necessary replace the cylinder;
-
openable cylinders: if there are significantly blackened areas, check
the deposits on the electrodes and clean them, using the specific
electrode and gasket kit.
•
Every year or no more than 2500 operating hours:
-
disposable cylinders: replace;
-
openable cylinders: if there are significantly blackened areas, check
the deposits on the electrodes and clean them, using the specific
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 humidifier as the water may conduct electricity.
9.4 Mechanically draining the water in the
cylinder
Drain due to gravity without activating the humidifier, recommended if:
•
humidifier decommissioned;
•
to empty the cylinder without switching the humidifier on.
Mechanical drain:
• make sure that the humidifier is not powered;
• remove the cover;
• activate the mechanical device under the cylinder (see part A, Fig. 9.e).

9.6 Cleaning and maintenance of the other
components
•
when cleaning 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:
fill solenoid valve. After having disconnected the cables and the
tubing, remove the solenoid valve and make sure the inlet filter is
clean; if necessary, clean with water and a soft brush;
manifold with drain pump. 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. Disconnect the power supply, remove the pump and
clean any impurities. Clean the tank from any deposits and check that
the water flows freely from the tank to the drain (corresponding to
the drain pump);
fill tank. Check that there are no obstructions or solid particles and
that the conductivity measuring electrodes are clean, remove any
impurities and rinse;
internal tubing kit. 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 fill and drain cycles (from 2 to 4), after which, applying the
safety procedure, check for any water leaks.
