ADDITIONAL COMPONENTS INFORMATION
Ozone Generator
The function of the ozone generator, is to
prevent the formation of bacteria,
consequently minimizing unpleasant smells
inside the tub and generally improving
hygiene conditions internally of the
appliance.
The component receives a power input of
220 V from the mainboard. An internal
electronic circuit is programmed to govern
the components and the duration for which
ozone is produced.
When activated to deliver ozone, the
solenoid valve of the device is open, and the
fan and ozone generator come into
operation.
How the Ozone Generator works as an option for preventing the proliferation of bacteria and
avoiding unpleasant smells:
The "O3" option is activated by pressing and holding the relative button. The option functions
continuously for 24 hours, alternating between ON and OFF at set intervals:
for the first three hours, the system operates 5 minutes On and 15 minutes Off, then, for a further
3 hours and 10 minutes, 8 minutes On and 30 minutes off; the time remaining until the end of 24
hours is divided into intervals of 8 minutes On and 15 minutes Off.
When the ozone generation system is not working correctly, the solenoid valve will emit
3 audible pulses each time it is activated.
If nothing is heard when activating the function, the fault is in the solenoid valve.

cycle content and duration when an Auto Cycle is selected.
