that ensures disconnection from the electrical mains, with an opening gap of the con-
tacts that enables total disconnection in overvoltage category III conditions.
Said disconnection devices must be provided in the mains power supply in compliance
with installation regulations.
The Ground 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 itting.
• 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 environments.
In the presence of motors with 500CFM 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 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
intended only for qualiied personnel
The hood can be installed in various conigurations.
The generic assembly steps apply to all installations; for each case, follow
the speciic 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.
