Grease and charcoal filter maintenance indicator - DU 4561
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:
Pressing keys B and D simultaneously for three seconds, LED F lights up and begins to flash the 1st speed led. After 1 second the 2nd speed led also flashes and the system emits a sound signal
