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 800m3/h or higher, a check valve is present to
prevent external air flowing back.
HOOD WITH INTERNAL RECIRCULATION (FILTERING)
In this model, the air passes through the charcoal filters to be
purified and recycled in the environment.
Ensure that the active carbon filters are assembled into the
hood, if not, install them as indicated in the assembly instruc-
tions.
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
Intended only 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.
The active carbon filters must be replaced every 3-4 months, depending on the
use of the hood.
For further details refer to the
“MAINTENANCE”
section.

eration.
Press ( ) the meter for 3 seconds to reset.
If the pushbutton panel is completely inactive, before con-
tacting 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 ser-
vice.
USING THE RADIO CONTROL
WARNINGS!:
Place the hood away from sources of electromagnetic waves (e.g.
microwave ovens), which could interfere with the radio control
and with the hood electronics.
The maximum operating distance is 5 metres, that may vary according to
the presence of electromagnetic 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
TIMER ON:
The motor automatically
switches off after 15 min.
The function is automatically disabled if
the motor is switched off (
key)
Command transmission active
ACTIVATION PROCEDURE
Before using the radio control, follow the procedure below on the
hood push-
button panel:
• Press LIGHT (
) and TIMER (
) simultaneously until all LEDs start flashing.
• Release the two keys and press LIGHT (
) again until all LEDs are lit up.
• Release LIGHT (
): now the receiver is active.
This procedure is also used to deactivate the receiver.
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.
