grease ﬁ lters or charcoal ﬁ lters; when the ﬁ lter alarm appears (i.e. when the central segment on the display goes

on), the grease ﬁ lters must be cleaned (30 hours of operation); when the central segment starts blinking, the grease

ﬁ lters must be cleaned and the charcoal ﬁ lters replaced (120 hours of operation). Obviously, if the hood is not a

ﬁ ltering model and does not have a charcoal ﬁ lter, clean the grease ﬁ lters both when the central segment goes

on and when it starts blinking. The ﬁ lter alarm can be seen when the motor is off and for about 30 seconds. To

reset the hour counter, keep the button pressed for 2 seconds while the alarm can be seen.

Controls shown in Fig. 16:

AUTOMATIC OPERATION WITH SENSOR:

Key A : switches the lights on/off. Key B : enables/disables “Automatic” function. When this function is selected,

an “A” appears on the display C, and the speed of the motor increases or decreases depending on the smoke,

odours and gas present in the kitchen. Display C : - indicates the automatic operation of the sensor (the letter

“A” appears);- indicates the motor speed selected automatically by the sensor; indicates the ﬁ lter alarm whenever

the central segment is illuminated or ﬂ ashing. Key D : decreases motor speed / Reset; decreases motor speed to

zero (stopping); in any case however, after approximately 1 minute, the hood resumes automatic operation at the

speed set by the sensor. Whenever the key is pressed during the display of ﬁ lter alarms, a RESET occurs, and the

counting of the hours resumes again. Key E : increases motor speed; in any case however, after approximately

1 minute, the hood resumes automatic operation at the speed set by the sensor.

Modiﬁ cation of sensor sensitivity: sensor sensitivity can be modiﬁ ed by operating as follows:

- stop the hood by pressing key B. – Simultaneously press keys D and E (the sensor’s sensitivity index will appear

on the display) - Pressing keys D or E, the sensor’s sensitivity will either increase or decrease (1 : minimum

sensitivity / 9: maximum sensitivity). – whenever the power supply is interrupted, the sensor will resume operation

with a sensitivity index of 5.

Warning: in order to avoid damaging the sensor, never use silicone products near the hood!

Controls shown in Fig. 17: Switch A: LIGHT; position 0: light off; position 1: light on. Switch B: MOTOR

SPEED: makes it possible to select the motor operating speed; position 0: motor off. C: Motor on light.

Controls shown in Fig. 18: Key A: turns the lights on/off; every 30 hours of operation the corresponding

pilot lamp (S) comes on to indicate that the grease ﬁ lters must be cleaned; every 120 hours of operation the

corresponding pilot lamp (S) ﬂ ashes to indicate that the grease ﬁ lters must be cleaned and the charcoal ﬁ lter

replaced. To restart the hour counter (RESET), hold the button A pressed down for about 1” (while the pilot lamp

S is on). Key B: drives the motor in ﬁ rst speed (the corresponding pilot lamp comes on); when holding it down

for about 1”, the motor cuts out; when pressing the button a second time (while the pilot lamp is on) , the TIMER

is activated and thus the motor stops after 5’ (the pilot lamp ﬂ ashes). Key C: drives the motor in second speed

(the corresponding pilot lamp comes on); when pressing the button a second time (while the pilot lamp is on) ,

the TIMER is activated and thus the motor stops after 5’ (the pilot lamp ﬂ ashes). Key D: drives the motor in third

speed (the corresponding pilot lamp comes on); when pressing the button a second time (while the pilot lamp is

on) , the TIMER is activated and thus the motor stops after 5’ (the pilot lamp ﬂ ashes). Key E: drives the motor

in fourth speed (the corresponding pilot lamp comes on); when pressing the button a second time (while the pilot

lamp is on) , the TIMER is activated and thus the motor stops after 5’ (the pilot lamp ﬂ ashes).

Pay special attention to the grease ﬁ lters: if the model purchased has the controls shown in Figure 15/16:

the grease ﬁ lters must be cleaned approximately once every 30 hours of operation (when the central segment on

the display goes on or starts blinking). Once the cleaned ﬁ lters are reinstalled, keep button R (Reset) pressed for

two seconds to reset the counter. If the model purchased has the controls shown in Figure 17: the grease ﬁ lter

must be cleaned periodically: exactly how often depends on use (at least once every other month). Wash out the

ﬁ lter using a neutral soap. If the model purchased has the controls shown in Figure 18: the grease ﬁ lters must be

cleaned approximately once every 30 hours of operation (when the light button lamp comes on) - Fig.18S). Wash

out the ﬁ lter using a neutral soap. Once the cleaned ﬁ lters are reinstalled, to reset the counter hold the light button

pressed down for about 1” (Fig.18A) while the corresponding pilot lamp (S) is on. IMPORTANT: The metal grease

ﬁ lters must be periodically cleaned following the above instructions, while the synthetic grease ﬁ lters (white colour)

must be replaced, according to the same cleaning frequency as the metal ﬁ lters.

Removing the grease ﬁ lters:

- For the model shown in Fig. 6: remove the metal grid by moving the 2 side fasteners (A). Remove the ﬁ lter

retainers (Fig. 19F) and then the metal (or synthetic) grease ﬁ lter (Fig. 19G).

- For the models shown in Fig. 7 and 8: remove the metal grease ﬁ lter by moving fastener B and turning the

ﬁ lter outwards.

Replacing the charcoal ﬁ lters: for ﬁ ltering hoods, the charcoal ﬁ lters must be replaced. If the model purchased

has the controls shown in Figure 15/16, the charcoal ﬁ lters must be replaced whenever the central segment of

the display starts blinking (i.e. every 120 hours of operation). If the model purchased has the controls shown in

Figure 17, the charcoal ﬁ lters must be replaced according to use: on the average once every 6 months. If the

model purchased has the controls shown in Figure 18, the charcoal ﬁ lters must be replaced each time the light

button (Fig.18S) lamp ﬂ ashes (i.e. every 120 hours of operation).

Removing the charcoal ﬁ lter/s: before removing the charcoal ﬁ lter/s, the grid and/or grease ﬁ lters will have to

be removed following the instructions shown at point 3 of “Extraction version installation” paragraph. Then remove
