INSTALLATION
only intended for qualified personnel
Before installing the hood,
carefully read the chapter
'SAFETY INSTRUCTIONS AND WARNINGS'.
TECHNICAL FEATURES
The technical specifications are exhibited on the labels located inside
the hood.
POSITIONING
The minimum distance between the highest part of the cooking
equipment and the lowest part of the hood is indicated in the in-
stallation instructions.
Generally, when the hood is placed over gas cookers, the distance must
be at least 65 cm (25.6''). However, according to an interpretation of
standard EN60335-2-31 dated 11-06-2002 of TC61 (sub-clause 6.12.1
meeting 15 agenda item 10.11), the minimum distance between the
cooker and lower part of the hood can be reduced to the quota report-
ed in the installation instructions.
Should the instructions for the gas cooker specify a greater distance,
this must be taken into consideration.
Do not install the hood outdoors and do not expose it to outdoor envi-
ronment (rain, wind, etc.).
ELECTRICAL CONNECTION
(only intended for qualified personnel)
Disconnect the equipment from electrical mains power
supply before carrying out any operations on the hood.
Ensure that the wires inside the hood are not disconnected
or cut:
in the event of damage, contact your nearest Servicing Depart-
ment.
Refer to qualified personnel for electrical connections.
Connection must be carried out in compliance with the provisions
of law in force.
Before connecting the hood to the electrical mains power supply,
check that:
• voltage supply corresponds with what is reported on the data plate
located inside the hood;
• the electrical system is compliant and can withstand the load (see
the technical specifications located inside the hood);
• the power supply plug and cable do not come into contact with
temperatures exceeding 158°F (70 °C);
• the power supply system is effectively and properly connected to
earth in compliance with regulations in force;
• the socket used to connect the hood is within reach.
In case of:
• devices fitted with cables without a plug: the type of plug to use is
a ''standardised'' one. The wires must be connected as follows: yel-
low-green for earthing, blue for neutral and brown for the phase. The
plug must be connected to an adequate safety socket.
• fixed equipment not provided with a power supply cable and plug,
or any other device that ensures disconnection from the electrical
mains, with an opening gap of the contacts that enables total dis-
connection in overvoltage category III conditions.
Said disconnection devices must be provided in the mains power
supply in compliance with installation regulations.
The yellow/green earth cable must not be cut off by the switch.
The Manufacturer declines all responsibility for failure to comply with
the safety regulations.
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
condensation from flowing back into the motor.
• the minimum required number of bends.
• the minimum required length to avoid vibrations and reduce the
suction performance of the hood.
You are required to insulate the pipes if it passes through cold envi-
ronments.
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 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 assem-
bly 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 re-
quired 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 automat-
ically 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.
