Grease and charcoal filter maintenance
indicator
This hood is fitted with a device that indicates when it is necessary to clean the
grease filter or the charcoal filter (if the hood is used in the recirculation version with a
charcoal filter).
On delivery, the hood is not supplied with a charcoal filter, so the saturation indicator
will be disabled.
If the hood is to be used with a charcoal filter, the saturation
indicator light must be enabled as follows:
Press button 1 to switch OFF.
Press buttons 3 and 5 simultaneously and hold them for 3 seconds. At first only the
grease filter LED F will illuminate, but when the charcoal filter LED C illuminates the
saturation indicator will be enabled.
To disable it: Press buttons 3 and 5 again simultaneously and hold
them for 3 seconds, until the charcoal filter LED C goes out.
Grease filter LED (F)
LED F will start to flash when it is time to clean the grease filter.
Cleaning will be necessary after 40 working hours. Always comply with the cleaning
instructions for the grease filter.
Charcoal filter LED (C)
The charcoal filter LED C will start to flash when the charcoal filter needs to be
replaced.
This operation is necessary after approximately 160 working hours.
Resetting the saturation indicator
After cleaning or replacing the filters, press button 1 for 3 seconds until the grease
filter LED F or the charcoal filter LED C stops flashing.
Warning! When resetting the saturation indicator it MUST be done in stand-by, never
disconnect the hood from the mains.
After resetting the saturation indicator switch the hood OFF.
