Grease filter signalling 
The grease filter is signalled by the display with number 1 
flashing after 40 hours of use. 
This means that the grease filter needs to be washed. 
The signalling is visible with the hood in ON state. 
To eliminate the grease filter signalling, press key “2” for 
more than 3”, until it turns off. 
The signalling can be eliminated with the hood in ON state. 
 
Carbon filter signalling (only for filtering version) 
The carbon filter is signalled by the display with number 2 
flashing after 160 hours of use. 

This means that the carbon filter installed must be replaced. 
The signalling is visible with the hood in ON state. 
To eliminate the carbon filter signalling, press key “2” for 
more than 3”, until it turns off. 
The signalling can be eliminated with the hood in ON state. 
 
In case both filters are signalled at the same time, numbers 1 
and 2 flash on the display alternately. 
The signalling can be reset by carrying out the above-
described procedure twice. 
First it resets the grease filter signalling, then the carbon filter 
signalling. 
 
In the standard mode the carbon filter signalling is not active. 
In case the filtering version hood is used, it is necessary to 

enable the carbon filter signalling. 
 
Activation of carbon filter signalling: 
Set the hood to OFF and keep keys “2” and “3” pressed 
contemporaneously for 3”. 
Numbers 1 and 2 flash alternately for 2”. 
Deactivation of carbon filter signalling: 
Set the hood to OFF and keep keys “2” and “3” pressed 
contemporaneously for 3”. 
Number 1 flashes for 2”. 
 
Temperature Alarm 
The hood is equipped with a temperature sensor which 
activates the motor at speed 3 in case the temperature in the 
display zone is too high. 
The alarm condition is indicated by the display with the letter t 

flashing. 
This condition remains as such until the temperature falls 
below the alarm threshold. 
This mode can be quit by pressing key “2”, “3” or “4”. 
Every 30” the sensor checks the ambient temperature of the 
display zone.
