9.2 Tank cleaning and maintenance
Replacement
Important: replacement must only be carried out by qualifi ed
personnel, with the humidifi er disconnected from the power
supply.
In normal conditions, the tank requires maintenance after one year
(or 1500 operating hours, if cleaned periodically), or if not used for an
extended period. Replacement is required immediately – even before
the scheduled period – should problems occur.
(For example, when scale inside the tank prevents correct operation of
the piezoelectric transducers)
Replacement procedure:
1.
switch the humidifi er off (switch "0"), and open the mains disconnect
switch (safety procedure);
2. disconnect the transducer power cable;
3. release the tank (the two tabs at the rear) and lift it vertically to remove it;
4.
clean or replace the transducers by removing the screws, see Fig. 9.b
(after replacement test water-tightness by fi lling the tank manually)
5. reconnect the transducer power cables;
6.
reposition the tank;
7.
switch the humidifi er on.
Periodical checks
Each year or after no more than 1500 operating hours:
•
-
clean the piezoelectric transducers
-
make sure the level sensor slides freely
Important: in the event of water leaks, disconnect the humidifi er
from the power supply and repair the leak
9.3 Cleaning and maintenance of other
components
•
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 transducers, loosen with the screwdriver the screws
shown in Fig. 9.b, being careful not to pull or force. An improper
maintenance can cause future water losses from the tank.
Maintenance checks on other components:
□ fi ll solenoid valve. After having disconnected the cables and hoses,
remove the solenoid valve, check the inlet fi lter and clean if necessary,
using water and a soft brush.
Important: after having replaced or checked the water circuit
components, make sure the connections are restored correctly.
