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 500 CFM or higher, a check valve is present to
prevent external air flowing back.
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.
For further details see the "MAINTENANCE" chap.
