Safety warnings
For the user
The cooker hood is designed to extract unpleasant odours from the
kitchen, it will not extract steam.
Always cover lighted elements, to prevent excess heat from
damaging the appliance. In the case of oil, gas and coal fired
cookers it is essential to avoid open flames.
Also, when frying, keep the deep frying pan on the cooker top/
cooker under careful control.
The hot oil in the frying pan might ignite due to overheating.
The risk of self-ignition increases when the oil being used is dirty.
It is extremely important to note that overheating can cause a fire.
Never carry out any flambé cooking under the hood.
Always disconnect the unit from the power supply before
carrying out any work on the hood, including replacing the light
bulb (take the cartridge fuse out of the fuse holder or switch off the
automatic circuit breaker).
It is very important to clean the hood and replace the filter at
the recommended intervals. Failure to do so could cause
grease deposits to build up, resulting in a fire hazard.
The appliance is not intended for use by young children or infirm
persons without supervision.
Older children must be supervised if using the appliance.
Young children should be supervised to ensure that they do not play
with the appliance.
WARNING - Ensure that the appliance is switched off before
replacing the lamp to avoid the possibility of electric shock.
This appliance is marked according to the European directive 2002/96/

potential negative consequences for the environment and human
health, which could otherwise be caused by inappropriate waste
handling of this product.
The symbol on the product, or on the documents accompanying
the product, indicates that this appliance may not be treated as

regulations for waste disposal.
For more detailed information about treatment, recovery and recycling
of this product, please contact your local city office, your household
waste disposal service or the shop where you purchased the product.

For the installer
When used as an extractor unit, the hood must be fitted with a
150mm diameter hose.
Should there already be a pipe of diameter 125 or 120 mm that
ducts to the outside through the walls, it is possible to use the 150/
125-120 mm reduction flange provided.
In this case the hood will be slightly noisier.
When installing the hood, make sure you observe the following
minimum distance from the top edge of the cooking hob/ring
surfaces:
electric cookers500 mm
gas cookers650 mm
If the instructions for installation for the gas hob specify a greater
distance, this must be adhered to.
The national Standard on fuel-burning systems specifies a maximum
depression of 0.04 mbar in such rooms.
The air outlet must not be connected to chimney flues or combustion
gas ducts. The air outlet must under no circumstances be connected
to ventilation ducts for rooms in which fuel-burning appliances are
installed.
The air outlet installation must comply with the regulations laid down
by the relevant local authorities.
When the unit is used in extraction mode, a sufficiently large
ventilation hole must be provided, with dimensions that are approximately the same as the outlet hole.
National and regional building regulations impose a number of
restrictions on using hoods and fuel-burning appliances connected
to a chimney, such as coal or oil room-heaters and gas fires, in the
same room.
Hoods can only be used safely with appliances connected to a
chimney if the room and/or flat (air/environment combination) is
ventilated from outside using a suitable ventilation hole approximately 500-600 cm2 large to avoid the possibility of a depression
being created during operation of the hood.
If you have any doubts, contact the relevant controlling authority or
building inspectors office.
Since the rule for rooms with fuel burning appliances is outlet hole
of the same size as the ventilation hole, a hole of 500-600 cm2,
which is to say a larger hole, could reduce the performance of the
extractor hood.
If the hood is used in its recirculation mode, it will operate simply and
safely in the above conditions without the need for any of the
aforementioned measures.
When the hood is used in its extraction mode, the following rules
must be followed to obtain optimal operation:
- short and straight outlet hose
65
- keep bends in outlet hose to a minimum
- never install the hoses with an acute angle, they must always
follow a gentle curve.
- keep the hose as large as possible (preferably the same diameter
as the outlet hole).
- the length should be no more than:
3 metres with one 90° bend
2 metres with two 90° bends
Bends of more than 90° will reduce the efficiency of the hood and
reduce the airflow.
Failure to observe these basic instructions will drastically reduce the
performance and increase the noise levels of the extractor hood.

Description of the Appliance
The cooker hood is designed to extract unpleasant odours from
the kitchen, it will not extract steam.
The hood is supplied as an extractor unit and can also be used with
a recirculation mode by fitting a charcoal filter.
In some models the charcoal filter is supplied. The hood, therefore,
can be used immediately in the recirculation mode. We advise
removing the charcoal filter to use the hood in the extraction mode.
Extraction mode
In this mode fumes are extracted to the outside via a hose
connected to the coupling ring A. Fig. 1.
In order to obtain the best performance the hose should have a
diameter equal to the outlet hole.
Should there already be a pipe of diameter 125 or 120 mm that
ducts to the outside through the walls, it is possible to use the 150/
125-120 mm reduction flange provided.
In this case the hood will be slightly noisier.

Recirculation mode
The air is filtered through a charcoal filter and returned to the
kitchen.
You will need an original charcoal filter for the recirculation mode.
(See Special Accessories).

Control Panel
Best results are obtained by using a low speed for normal conditions
and a high speed when odours are more concentrated.
Turn the hood on a few minutes before you start cooking.
The hood should be left on after cooking for about 15 minutes or
until all the odours have disappeared.
The control switches are located on the hoods front panel:

1 - ON (stand-by - illuminated key) / OFF switch.
Press once or more to obtain the function desired:
Stand-by (dot "b" on the display is illuminated): the hood is ready
to function, the safety procedure is activated (see next page
Safety procedure).
OFF: all the functions are switched off except the illumination.
2 - Light ON/OFF
3 - Display
4 - Manual(stand by)/Automatic (sensors - Led S will illuminate).
Press once to switch ON the Automatic mode, press again to
switch OFF (stand-by / Manual mode).
Automatic function:
The hood switch ON (extraction) on the basis of the change in the
normal environmental conditions that the hood notices through
its sensors (see next page Sensor test) .
The leds of the display will turn on alternatively in proportion to the
suction power setting.
Attention! The hood is equipped with an automatic system that
establishes what the normal environmental conditions are.
In the case of abnormal operation, calibration can be carried out
automatically or manually (see next page Automatic
calibration and Manual calibration).

6 - Intensive speed on/off. The Intensive speed runs for 5 minutes:
If the hood is on when the Intensive speed is activated, the hood
will revert to previous speed after 5 minutes.
If the hood is off when the Intensive speed is activated, the hood
