These instructions are designed to tell you of the various technical details
of your cooker hood and to make you familiar with its use. Since these
instructions cover more than one type of hood within the same series, it may
be that reference is made to components that do not form part of the hood
that you are installing. Fittings can vary from country to country. We reserve
the right to modify the product without any notice always with the aim of
improvements and in compliance with the relevant norm.
General description
The appliance can be used as a canopy hood or can be mounted beneath
a wall cupboard and is suitable for use as an exhaust hood or as a
recirculating hood; if an exhaust facility (an exhaust duct or a ventilating
shaft) is available, then we recommend the hood be installed as an exhaust
hood for then, most of the smells and vapors that arise when cooking or frying
can be almost completely removed from the kitchen. The grease filter that
is fitted removes any grease particles from the vapors so that your kitchen,
the kitchen furniture and the walls remain for the most part free of grease
and other particles that could give rise to unpleasant odours.
Exhaust version
The hood must be connected by the flange (supplied as part of the hood)
to a duct to vent all the exhausted air outside the kitchen. Over horizontal
areas, if any, the duct must be slanted about 10% upwards from upstream
to downstream.
N.B. The efficiency of the exhaust hood decreases as the length of the ducts
and number of elbows increase. When using the exhaust version, follow
these rules: Do not connect the exhaust hood to chimneys, flues, and air
ducts serving the room. Before venting into exhaust flues and ducts no
longer in use, ask for the approval of the person or agency responsible for
the building. The evacuated air must not be let into a warm air duct. For the
evacuation of the exhausted air please note ufficial instructions.
Suggestions for using the hood in exhaust position
When an exhaust hood and a heat source requiring ambient air (e.g. gas,
oil, coal stoves, etc.) are used at the same time, attention is required because
the air necessary for combustion is exhausted from the room through the
hood and this creates depression. There is no such danger when the
maximum depression in the room is 0,04 mbar. In this condition no exhaust
gas from the heat source is piped. To assure this condition, make openings
in the room which cannot be closed (doors, windows, etc. are not sufficient)
and through which the air necessary for combustion can freely flow.
Note: All the exhaust ductwork in the apartment or house should be studied.
In case of doubts, get advice or authorization from the person or agency
responsible for the building. When using gas burners, gas ovens, etc. as
well as when using the hood in the filter version, these precautions are not
Filter version
This version is used when no exhaust duct to the outdoors is available. The
air is purified by an active vegetable carbon filter and recycled into the room.
Make sure the carbon odor filter is inserted.
Use Summer/Winter
The appliance enables you to avoid unnecessary heat loss in winter.
It can be used either in the exhaust or recirculating mode, by simply
moving the relevant lever (Pict. 7/1).
For recirculating use check that the carbon filter is inserted and the
(Pict. 9/1).

The hood must be mounted over the centre of the cooking area at a
minimum height above the hob of 650 mm for gas stoves and 550 mm
for electric stoves. Note: such dimensions are also subject to the
safety regulations in effect in your country which must be checked.
Before drilling the wall make sure that no pipes or cables will be
Fastening the cooker hood beneath a wall cupboard
1. Turn the wall cupboard upside down.
2. Using a 4,5 mm bit, drill the four fastening holes in the bottom of the
3. Cut the exhaust opening for a pipe of (130 mm diameter) and fasten the
pipe flange to the hood.
4. Turn the cupboard back over and stand it on the top of the cooker hood
and fasten the hood to the cupboard by means of four screws screwed
through the holes that were drilled in the bottom of the cupboard.
Electric connection
Make sure the supply voltage ratings correspond with those stated on the
appliance data plate.
This appliances is double insulated, do not connect to earth.
Attention: If the appliance does not have a plug, when making a fixed
installation, a cutoff device must be used to assure omnipolar disconnection
the mains. The cutoff distance of the contacts must be at least 3 mm. If the
appliance is provided with a supply cord and plug, the appliances must be
positioned so that the plug is accessible.
Note — A damaged power supply cord must be changed by the Service.
Using the cooker hood
The cooker hood should be switched on either before or at the same as
cooking or frying commences. The grease and carbon filters are more
effective if the fan is not switched off immediately after cooking or frying is
completed, but only after a period of some 20-30 minutes.
User instructions
Switch on the hood when you start cooking. When you finish wait 2030 minutes before switching it off in order to keep the filters operating
The hood is fitted with a slider with four switches and a motor operating
display (Pict. 3):
A - Light switch
B - Motor/Speed switch
Safety rules
Do not do any flambe cooking underneath the hood. When frying, never
leave the pan alone because the cooking oil could flare up. Clean all the
surfaces frequently to avoid danger of fire. It is also important to remove and
clean or substitute frequently the filter installed in the hood.
Note: When performing any maintenabce operations, disconnect the
plug from the socket. Vapours and odours in the air are exhausted first
through the grease filter and (if the hood is the recirculating version)
then through the carbon odour filter. The efficiency of the appliance
depends on the condition of the filters. Clean the hood outside with a
sponge soaked with liquid detergent. Do no use any products containing
abrasive substances or acids or strong alkalies such as oven cleaner.
Note: in order to simplify cleaning and maintenance operations the
appliance allows you to extract the filtering module by removing the grid
and by pressing on the handles (Pict. 4/2) and all the screws (Pict. 8/
1). Push the levers (Pict. 8/2) towards the rear and remove it. Repeat
the operation in the opposite way in order to reinstall this module,
making sure that the security levers (Pict. 8/2) are pushed towards the
rear and overgo the plate tooth (Pict. 8/3).
N.B. The Lamps rating must never be higher than that indicated inside
the hood.
Grease filter
This absorbs vapor-suspended grease particles and protects the kitchen
and furniture from greasy residues. There are three types of filter:
1. Acrylic. It can be washed at more or less frequent intervals depending
on how often the hood is used. In any case, it should be washed every
thirty days of hood operation. To do so, wash the filter by hand in warm
soapy water (do not wring the filter; press it in a cloth to dry).
2. Special paper (with red signs on the top of the sheet). Not- washable:
change the filter when the red signs are visible from below through the
grille holes.
3. Aluminum layers. The filter should be washed every 10 to 15 days (in
normal operating conditions). Dip the filter into a degreaser solution or
put it in the dish washer. Make sure not to damage the filter, which is made
of several layers of thin alloy, by hitting or crushing it. The aluminium filter
will may change colour, that will have no influence of the efficiency of the
filter, may it will improve it.
Active carbon odour filter
Attention! The exhaust air passed through the active carbon filter and
is then cleaned. This filter cannot be washed and will have to be
replaced approximately every six months.
Grease filter removal
Grab the opening tongue at the filter, pull it into your direction and move the
filter downwards (Fig. 4/1) To reinstall it operated reversed. For the models
with a filtergrid it is sufficient to push the handle (look fig.4/2). Unhook the
filterfastening and change the greasefilter.
Carbon filter replacement
(for filtering hoods only)
Pull the knob of the carbon filter cover (Pict. 5/1). Remove the filtering
cartridge by means of the handles provided (Pict. 6/1) drawinf them
downwards. Insert the new filtering cartridge making sure that the
printed on it is visible when inserted
symbol "front filtering"
(Pict. 9/1).
N.B.: The filtered air can be conveyed to the hood rear outlet by
inserting the carbon filter with the symbol "rear filtering"
visible when inserted (Pict. 9/2). Or by simply turning the catridge by
180° if already inserted with "front filtering" showing if the rear outlet is
to be used.
