D = SPEED II
E = SPEED III
F = AUTOMATIC STOP TIMER - 15 minutes (*).
If your appliance has the INTENSIVE speed function, from
speed THREE, press key E for 2 seconds and it will be activa-

By pressing key F for two seconds (with the hood switched
off) the "clean air" function is activated. This function switches
the appliance on for ten minutes every hour at the first speed.
As soon as this function is activated the motor starts up at the

C must flash at the same time. After ten minutes the motor
switches off and the LED of key F remains switched on with
a fixed light until the motor starts up again at the first speed
after fifty minutes and keys F and C start to flash again for ten
minutes and so on. By pressing any key for the exclusion of
the hood light the hood will return immediately to its normal
functioning (e.g. if key D is pressed the "clean air" function is
deactivated and the motor moves to the 2nd speed straight
away. By pressing key B the function is deactivated).
