of the instructions included in this manual.
INSTALLATION
The hood may be in filtering or in ducting
version (see A-B pag.2). Decide from the
outset which type is to be installed. For bet-
ter efficiency, we recommend installing the
hood in the ducting version (if possible).
FILTERING VERSION (A)
The cap purifies the air and
recycles the clean air backburn
in the room. For this version, you
need as much as a carbon filter.
In the flue version, the upper flue
duct must have the evacuation
slots located at the top.
DUCTING VERSION (B)
The hood purifies the air and eva-
cuates it to the outside through
an exhaust duct or hole (diameter
150 mm).
Roof Venting (B)
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
en es
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 mainte-
nance 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.
