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 500 CFM 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 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 qualified personnel
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.
SRS SYSTEM SETTING
The SRS system reduces the maximum air flow rate that can be set
in the hood.
This makes the hood compliant with local building regulations.
