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 tting must be connected via a
pipe, to an external output.
The outlet pipe must have:
• a diameter not less than that of the hood tting.
• a slight slope downwards (drop) in the horizontal sections to prevent conden-
sation from owing 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 owing 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 lters to be
puried and recycled in the environment.
Ensure that the active carbon lters 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 tting of the motor.
ASSEMBLY INSTRUCTIONS
only intended for qualied personnel
The hood can be installed in various congurations.
The generic assembly steps apply to all installations; for each case,
follow the specic 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-o
function which will allow the hood to turn o 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 lters must be cleaned every 30 hours of operation.
The active carbon lters must be replaced every 3-4 months, depending on the
use of the hood.
For further details see the “MAINTENANCE” chap.
