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:
Set in "OFF" the hood.
Press buttons 1 and 2 simultaneously and hold
them for 3 seconds. At first only the grease filter
LED 3 will light up, but when the charcoal filter
LED 4 lights up the saturation indicator will be
enabled.
To disable it: Press buttons 1 and 2 again
simultaneously and hold
them for 3 seconds, until the charcoal filter LED
4 goes out.
