Motor ON/OFF

Motor OFF
Long impulse:

 change light tone from 2700K to 5600K

Increase speed from 1 to 4

Speed 4 is only active for a few 
minutes, then speed 3 activates.

The speeds are indicated by the 
LEDs on the keys:

 Speed 1

 Speed 2

 Speed 3

 Speed 4 

("+" LED flashing)

Reduce speed from 4 to 1

Light on/off
Short impulse:

 turn light on and off

Long impulse: 

adjust intensity

TIMER

 (red LED flashing)

Auto switch-off after 15 min.
The function deactivates (red LED off ) if:
- The TIMER key (

) is pressed again.

- The ON/OFF key (

) is pressed.

If the pushbutton panel is completely inactive, before contacting 
the Technical assistance service, disconnect power temporarily 
to the appliance (about 5“), possibly by acting on the main 

switch, to restore normal operation.
If this measure has no effect, contact the Technical assistance service.

 USING THE RADIO CONTROL

WARNINGS!:

Place the hood away from sources of electro-
magnetic waves (e.g. microwave ovens), which 

could interfere with the radio control and with the hood 
electronics. The maximum operating distance is 5 me-
tres, that may vary according to the presence of electro-
magnetic interferences. 
Radio control operated at 433.92MHz.
The radio control consists of two parts:
- the receiver built into the hood;

- the transmitter shown here in the figure.

DESCRIPTION OF TRANSMITTING COMMANDS

UP

Motor switch-on and speed increase from 1 to 4. Speed 4 is only 
active for a few minutes.

DOWN

Speed decrease and motor switch-off.

Light on/off
Short impulse: 

turn light on and off

Long impulse:

 adjust intensity

TIMER ON:

 The motor automatically switches off after 15 min.

The function is automatically disabled if the motor is switched off

Command transmission active

RADIO CONTROL CODE CHANGE

With only one radio control, go directly to point 2.
With several radio controls in the same room, a new code can be created by 
following the procedure below.

Disconnect the power to the hood before starting the procedure.

FUMES DISCHARGE

EXTERNAL EXHAUST HOOD (SUCTION)

In this version the fumes and vapours are discharged outside 
through the exhaust pipe.
To this end, the hood outlet fitting must be connected via a 
pipe, to an external output.

The outlet pipe must have:
•  a diameter not less than that of the hood fitting.
•  a slight slope downwards (drop) in the horizontal sections to prevent conden-

sation from flowing back into the motor.

•  the minimum required number of bends.
•  the minimum required length to avoid vibrations and reduce the suction per-

formance of the hood.

  You are required to insulate the pipes if it passes through cold environments.
  In the presence of motors with 800m

3

/h or higher, a check valve is present to 

prevent external air flowing back.

Deviation for Germany:
when the kitchen hood is used at the same time as appliances that are powered by 
energy other than electricity, the negative pressure in the room must not exceed 4 Pa 
(4 x 10-5 bar).

HOOD WITH INTERNAL RECIRCULATION (FILTERING)

In this model, the air passes through an optional filter unit in 
the ceiling to be purified and recycled in the environment.

In this version the check valve must not be assembled: remove it if it is 
on the air outlet fitting of the motor.

ASSEMBLY INSTRUCTIONS

only intended for qualified personnel

The hood can be installed in various configurations.

The generic assembly steps apply to all installations; for each case, 
follow the specific steps provided for the required installation.

OPERATION

WHEN TO TURN  ON THE  HOOD?

Switch on the hood at least one minute before starting to cook to direct fumes 
and vapours towards the suction surface.
After cooking, leave the hood operating until complete extraction of all vapours 
and odours. By means of the Timer function, it is possible to set auto switch-off 
function which will allow the hood to turn off automatically after 15 minutes of 
operation.

WHICH SPEED IS TO BE SELECTED?

1st speed: 

maintains the circulation of clean air with low electricity consumption.

2nd speed: 

normal conditions of use.

3rd speed:

 presence of strong odours and vapours.

4th speed:

 rapid disposal of odours and vapours.

WHEN SHOULD THE FILTERS BE WASHED OR REPLACED?

The metal filters must be cleaned every 30 hours of operation.
