“Ultrasound for fancoil” +0300059PT - rel. 1.6 - 06.10.2020
NOTICE:
•
the tightening torque of the screws that fasten the transducer must
be 0.4±0.05Nm;
•
beware of electrostatic discharges, so as to prevent damage to
electronic components.
Replacement procedure:
3.
switch the humidifier off (switch “0”), and open the mains disconnect
switch (safety procedure);
4. disconnect the transducer power cable;
5. release the tank (the two tabs at the rear) and lift it vertically to
remove it;
6. clean or replace the transducers by removing the screws (figure).
After replacement test water-tightness by filling the tank manually;
7.
reconnect the transducer power cables;
8.
reposition the tank;
9. switch the humidifier on.

Periodical checks
•
Every year or no more than 1500/5000 operating hours respectively
with mains/demineralised water:
- clean the piezoelectric transducers
-
make sure the level sensor slides freely
NOTICE: in the event of water leaks, disconnect the humidifier from the
power supply and repair the leak
13.4 Cleaning and maintenance of other
components
•
Using humiSonic with demineralised water , transducers last about
10,000 h . If it is used another type of water or if the water has impurities
and dirt , the transducers useful life is reduced proportionally
•
when cleaning plastic parts do not use detergents/solvents;
•
descaling can be performed using a 20% acetic acid solution, followed
by rinsing with water;
•
To replace the drivers and transducers, loosen the screws shown in the
figure with a screwdriver. Before applying the new driver , spread on
the back of the heat sink in contact with the tank, a layer of conductive
paste. The lack of the conductive paste may cause malfunctions. To
insert new transducers, observing the direction of insertion (
please,
pay attention to the print before removing the old one).
NOTICE: the tightening torque of the screws that fasten the transducer
must be 0.4±0.05Nm.
Maintenance checks on other components:
Ƒ
fill solenoid valve. After having disconnected the cables and hoses,
remove the solenoid valve, check the inlet filter and clean if necessary,
using water and a soft brush.
NOTICE: after having replaced or checked the water circuit components,
make sure the connections are restored correctly.
