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 800m3/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 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
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 consump-
tion.
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.

MAINTENANCE
Before cleaning or carrying out maintenance operations, discon-
nect the equipment by removing the plug or switching off the
main switch.
Do not use detergents containing abrasive, acidic or corrosive substances
or abrasive cloths.
Regular maintenance guarantees proper operation and performance over time.
Special attention is to be paid to the metal anti-grease filters : frequent clean-
ing of the filters and their supports ensures that no flammable grease is accu-
mulated.
CLEANING OF EXTERNAL SURFACES
You are advised to clean the external surfaces of the hood at least once every
15 days to prevent oily substances and grease from sticking to them. To clean
the brushed stainless steel hood, the Manufacturer recommends using "Magic
Steel" wipes.
Alternatively and for all the other types of surfaces, it can be cleaned using a
damp cloth, slightly moistened with mild, liquid detergent or denatured alcohol.
Complete cleaning by rinsing well and drying with soft cloths.
