hood in the ducting version (if possible).
FILTERING VERSION (A)
The hood purifies the air and
recycles the clean air backb into the
room. For this version, the following
is required: a theft-proof cover, a
reducer and charcoal filter. In the
version with flue, the upper flue
must have the air evacuation slots
positioned in the upper part and
the deflector must be used in place
of the anti-theft cover. The upper
flue air evacuation slots must be
positioned at the top.
DUCTING VERSION (B) (C)
The hood purifies the air and
evacuates it to the outside through
an exhaust duct or hole (diameter
150 mm).

AIR VENT
(for ducting versions)
! Prepare the hole and the air vent duct
(150 mm diameter - not provided with the
product).
! Use a duct of the minimum indispensible
length.
! Use a duct with as few elbows as possible
(maximum elbow angle: 90°).
! Avoid drastic changes in the duct cross-
section.
! Use a duct with an as smooth as possible
inside.
! The duct must be made of certified mate-
rial.
! Do not connect the hood to smoke exhaust
ducts for the products of combustion (boi-
lers, fireplaces, stoves, etc).
! For the air vents comply with the pro-
visions laid down by the competent au-
thorities. In addition, the air must not be
evacuated through a hole in the wall unless
specifically intended for this purpose.
! Fit air intakes in the room to prevent the
hood from creating a negative pressure
in the room (which must not exceed 0.04
mbar); if the hood is used at the same time
as non-electrical equipment (gas-, oil- and
charcoal-fired stoves, etc.) the exhaust gas
may be sucked in by the heat source.
ASSEMBLY
! WARNING: Very heavy product; hood han-
dling and installation must be carried out by
at least two persons.
! WARNING: Wear gloves and goggles when
carrying out installation and maintenance
operations.
! WARNING: Failure to install the screws
or fixing device in accordance with these
instructions may result in electrical hazards.
!The minimum distance between the
supporting surface for the cooking equip-
ment on the hob and the lowest part of the
range hood must be not less than 45cm
from electric cookers and 45cm from gas
or mixed cookers. If the instructions for
installation for the gas hob specify a greater
distance, this must be adhered to.
! Expansion wall plugs are provided to secu-
re the hood to most types of walls/ceilings.
However, a qualified technician must verify
suitability of the materials in accordance
with the type of wall/ceiling. The wall/ceiling
must be strong enough to take the weight
of the hood. Do not tile, grout or silicone.
! In case of doubt, consult an authorised
service assistance centre or similar qualified
person.

figures at pag. 2/10
ELECTRICAL CONNECTION
The mains power supply must correspond
to the rating indicated on the plate situated
inside the hood. If provided with a plug
connect the hood to a socket in compliance
with current regulations and positioned in
an accessible area, after installation. If it not
fitted with a plug (direct mains connection)
or if the plug is not located in an accessible
area, after installation, apply a double pole
switch in accordance with standards which
assures the complete disconnection of the
mains under conditions relating to over-cur-
