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 HU315ful 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;
•
open and remove the cover;
•
remove the steam hose from the cylinder;
