• 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
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, air passes through the active carbon filters HP (op-
tional) to be purified and is then recycled into the environment.
Ensure that the active carbon filters HP are assembled into the
hood, if not, install them as indicated in the assembly instructions.
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 personnel qualified
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.

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 me-
tres, that may vary according to the presence of electromagnetic interfer-
ences.
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.
