Installation, Operation & Maintenance Manual

Maintenance

Periodic checks

•

After one hour of operation:

For both disposable and cleanable cylinders, check that there are no

significant water leaks.

•

Every fifteen days or no more than 300 operating hours:

For both disposable and openable cylinders

check operation, that there are no significant water leaks and the general condition of the cylinder. Check
that during operation there is no arcing between the electrodes.

•

Every three months or no more than 1000 operating hours:

For disposable cylinders, check operation,

that there are no significant water leaks and, if necessary, replace the cylinder; for cleanable cylinders,
check that there are no blackened parts of the cylinder. If there are blackened parts of the cylinder, 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

cleanable cylinders check operation, that there are no significant water leaks, the general conditions of the
cylinder, check that there are no blackened parts of the cylinder: 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.

•

After five 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 out. As a
precaution, check the deposits and the blackening of the wall of the cylinder, and replace the cylinder if
necessary.

CAUTION:

always disconnect the main power before touching the cylinder in the event of leaks, as current may flow

through the water.

Cylinder maintenance

The life of the cylinder depends on a number of factors, including: the amount and type of mineral in the water, the
correct use and sizing of the humidifier, and the output, 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 warnings

The humidifier and its cylinder contain live electrical components and hot surfaces, and therefore all service and/or
maintenance operations must be performed by expert and qualified personnel, who are aware of the necessary
precautions. Before performing any operations on the cylinder, check that the humidifier is disconnected from the
power supply. Remove the cylinder from the humidifier only after having drained it completely using the manual drain
button or procedure. Check that the model and the power supply voltage of the new cylinder correspond to the data
on the rating label.

Replacing the cylinder
IMPORTANT WARNING:

the cylinder may be hot. Allow it to cool before touching it or use protective gloves.

To replace the cylinder:

•

completely drain the cylinder by pressing and holding the manual drain switch or by pressing the

and

buttons simultaneously for 2 seconds to force a manual drain. This procedure can be stopped at any time
by again pressing the

and

buttons for 2 seconds;

•

turn the humidifier off and disconnect the main power;

•
