7. CYLINDER MAINTENANCE
Important: the cylinder may be hot. Let it cool down before
touching it or use protective gloves.
7.1 Cylinder replacement
•
completely drain the water contained in the cylinder;
•
turn the appliance off and open the disconnect switch on the mains
power line (safety procedure);
•
remove the steam hose from the cylinder;
•
disconnect the electrical connections from the top of the cylinder;
•
release the cylinder from the fastening device and lift it up to remove it;
•
fi t the new cylinder in the humidifi er by performing the previous
operations in reverse.
7.2 Cylinder maintenance (see cylinder
instruction sheet)
The life of the cylinder depends on several factors, including: the
complete fi lling with lime scale and/or the partial or complete corrosion
of the electrodes, the correct use and sizing of the humidifi er, the output,
and the quality of the water, as well as careful and regular maintenance.
Due to the aging of the plastic and the consumption of the electrodes,
even an openable steam cylinder has a limited life, and it is therefore
recommended to replace it after 5 years or 10,000 operating hours.
Important:
the humidifi er and its cylinder contain live electrical
components and hot surfaces, and therefore all service and/or
maintenance operations must be performed by expert and qualifi ed
personnel, who are aware of the necessary precautions. Before
performing any operations on the cylinder, check that the humidifi er
is disconnected from the power supply; carefully read and follow the
instructions contained in the humidifi er manual. Remove the cylinder
from the humidifi er only after having drained it completely. Check that
the model and the power supply voltage of the new cylinder correspond
to the one being replaced.
7.3 Periodical checks
•
After one hour of operation: for both disposable and openable
cylinders, check that there are no signifi cant water leaks.
•
Every fi fteen days or no more than 300 operating hours: for both
disposable and openable cylinders check operation, that there are
no signifi cant water leaks and the general condition of the casing.
Check that during operation there are no arcs or sparks between the
electrodes.
•
Every three months or no more than 1000 operating hours: for
disposable cylinders, check operation, that there are no signifi cant
water leaks and, if necessary, replace the cylinder; for openable
cylinders, check that there are no markedly blackened parts on the
casing: if this is the case, check the condition of the electrodes, and
if necessary replace them together with the O-rings and the cover
gasket.
•
Annually or no more than 2500 operating hours: for disposable
cylinders, replace the cylinder; for openable cylinders check operation,
that there are no signifi cant water leaks, the general conditions of the
container, check that there are no markedly blackened parts on the
casing; replace the electrodes together with the O-rings and the cover
gasket.
•
After fi ve years or no more than 10,000 operating hours: for both
disposable and openable cylinders, replace the cylinder.
After extended use or alternatively when using water with a high salt
content, the solid deposits that naturally form on the electrodes may
reach the stage where they also stick to the inside wall of the cylinder;
in the event of especially conductive deposits, the consequent heat
produced may overheat the plastic and melt it, and, in more severe cases,
puncture the cylinder, allowing water to leak back into the tank.
As a precaution, check, at the frequency recommended further on, for
deposits and the blackening of the wall of the cylinder, and replace the
cylinder if necessary.
Warning: always disconnect the appliance before touching the cylinder
in the event of leaks, as current may be running through the water.
7.4 Replacement and maintenance of other
components
Fill solenoid valve

: after having disconnected the cables and the
tubing, remove the solenoid valve and check the condition of the inlet
fi lter; clean if necessary using water and a soft brush.

Supply and drain manifold (drain solenoid valve/pump assembled) :
check that there are no solid residues in the cylinder attachment, remove
any impurities. Check that the gasket (O-ring) not is damaged or cracked;
if necessary, replace it.
Drain solenoid valve/pump

: disconnect the power supply, remove
the coil (solenoid valve version), unscrew the fastening screws and
remove the valve body (pump version); remove any impurities and rinse;
Supply tank & conductivity meter

: check that there are no
obstructions or solid particles and that the electrodes for measuring the
conductivity are clean, remove any impurities and rinse.
Hose kit

: check that the hoses are free and do not contain impurities;
remove any impurities and rinse.
