Caution

Use
The hood is designed to be used
either as a ducting version or as a
filter version.
Ducting version
This version conveys the fumes to the
outside of the building via an
extraction duct that is fixed to the
connecting flange.
The diameter of the extraction duct
must be the same as that of the
connecting ring.
Warning! The duct is not supplied
and must be purchased separately.
In the horizontal section, the
extraction duct must have a slight
upwards inclination (about 10°) so
that it can
convey the air to the outside more
easily.
If the hood is fitted with activated
carbon filters, they should be
removed.
Connect the hood to the extraction
ducts and wall outlets that have a
diameter that is the same as the air
outlet (connecting flange).
Using ducts and wall outlets that
have a smaller diameter will reduce
suction and lead to a large increase in
noise.
We decline any responsibility if these
instructions are not complied with.
! Use a duct of the minimum
length necessary.
! Use a duct with as few bends as
possible (maximum angle: 90°).
! Avoid drastic changes in the duct
cross-section.
! Use a duct that is as smooth as
possible inside.
! The duct must be made of
certified material.
Filter version
The air will be degreased and
deodorised before being returned to
the room. To use the hood in this
version you have to install an
additional activated carbon filtration
system.
Models without a suction motor only
operate in ducting mode and must be
connected to an external suction
device (not supplied).
Connection instructions are supplied
with the external suction unit.
