Dismantling the panels (to access the front driver board and the tank)
After having removed the cover (C) on the terminal block, work on the

Piezoelectric transducer
Note: the atomisation capacity of the piezoelectric transducer
gradually decreases with use. It must be replaced after around 10,000
operating hours (depending on water quality), even if the unit can
continue operating while eff ective capacity still responds to requirements.
To remove the piezoelectric transducer:
1. turn the humidifi er body over and identify the piezoelectric transducer
to be replaced;
2. unplug the electrical cable terminals from the corresponding driver
board;
3. using a socket wrench (5.5), loosen the fastening nuts, remove the
transducer and replace it;
4. when replacing the transducer, pay attention to the white markings
(arrow): the top line of transducers has the markings on the right, and
the bottom line has the markings on the left. The transducer must
have the markings positioned in the same ways as the adjacent ones.
Note: the tightening torque of the nuts that fasten the transducer
must be 4±0.5 kg cm
Important: if the transducer is fi tted rotated 180°; incorrect
assembly will cause a reduction in atomised water production and
potential humidifi er malfunctioning.
