10.4 Maintenance
Important : before performing any operations:
•
power the unit off at the switch (off ) on the control panel;
•
empty the water from the tank.
The fi ll valve is normally closed and the drain valve is normally open,
consequently, when powering down the humidifi er, the unit is drained
automatically.
Note: preventive maintenance on the humidifi er is recommended
to ensure optimum system performance. Maintenance includes:
•
checking tightness of the electrical connectors;
•
cleaning and visual inspection of the components;
•
checking water level and making sure there are no leaks.
Important :
•
the piezoelectric transducer is very delicate: when cleaning the inside
of the tank, make sure not to scratch it, for example with a screwdriver;
•
tighten the nuts applying the maximum allowed torque (8 ± 0.5
kg·cm). Excessive tightening torque may damage the humidifi er.
It is recommended to periodically check operation of the piezoelectric
transducers, the corresponding driver boards and the fans, by carrying
out a visual inspection:
1.
make sure there a water column above each of the piezoelectric
transducers during humidifi er operation;
2.
check that the LEDs on the driver boards are on and are yellow during
humidifi er operation.
10.5 Maintenance operations
Routine maintenance on humidifi ers operating on demineralised water
involves cleaning all the parts in contact with the water:
a. fi ll/drain lines;
b. water tank.
Special maintenance and repairs involve replacement of:
a. fi ll/drain solenoid valve;
b. driver board;
c. piezoelectric transducer;
d. electronic control board.
10.6 Maintenance intervals
Maintenance intervals depend on water quality and the quantity
of atomised water produced. An operating hour counter (eff ective
production) and a unit operating hour counter (total hours) can be set,
together with a maintenance hour counter, after which the display shows
a warning message. See alarm CL.

The use of demineralised water minimises maintenance requirements.
Note: it is recommended to perform special maintenance and
repairs at least once a year, irrespective of the number of operating hours
shown on the operating hour counter.
10.7 Replacing the components
To access the load/drain solenoid valve, remove closure on the termianl
block-side.

1.
loosen and remove the screws (A) and release the cover (C) at point
(B) to remove. If necessary, loosen the screws (V) to remove the lifting
handle (M).
Drain solenoid valve
1.
unplug the electrical connectors and move the spring fasteners so
as to remove the hoses, then remove the block (D): elbow connector,
drain valve, T-connector.
