INSTALLATION
This hood has been designed to be wall-mounted above a cooking hob.It can be installed
under a wall unit or directly onto a wall.It can work either by ducting system (external
discharge)or filter (internal recirculation).
SAFETY WARNINGS
• Before starting the installation,consideration should be given to the difficulties to be
found during installation.The installation work must be undertaken by a qualified and
competent person in conformity to the rules concerning the evacuation of contaminated
air.The manufacturer disclaims all liability for any damage or injury caused as a result
of not following the instructions for installation contained in the following text.
• When used in the extraction mode,the cooker hood ducting must not be connected to
a flue which is used for exhausting fumes from appliances supplied with energy other
than electric,such as a central heating flue or water heating flue.
• When installed,the hood must be positioned at least 65 cm above the hotplate.
• If the room where the cooker hood is to be used contains a fuel burning appliance
such as a central heating boiler then this must be of the room sealed or balanced flue
type.If other types of flue or appliance are fitted,ensure that there is an adequate
supply of air into the room.When the cooker hood is used in conjunction with appliances
supplied with energy other than electric,the negative pressure in the room must not
exceed 0,04 mbar to prevent fumes being drawn back into the room by the cooker
hood.
Wall installation
The hood can be supplied with two different fixing kits:
a)screws,plugs and safety square.
b)screws,plugs and metal brackets.
Fixing with screws
Using the cardboard template,mark and drill
the holes on the wall (2 holes Ø 8 mm see
instructions on the template),insert the plugs
in the holes,tighten both 4,2 x 44,4 screws
(supplied)leaving about 5 mm unscrewed,
hook the hood onto the screws (fig.1)and
secure tightly from inside (fig.2).Mount the
safety square (supplied)above the hood (fig.
3).

Fixing with brackets
• Using the cardboard template,mark and drill
the holes on the wall (4 holes Ø 8 mm see
instructions on the template).
• Fix the metal brackets with screws and plugs
(supplied),hook the hood onto the brackets
(fig.4).
• Fix the hood with two knobs (supplied)(fig.5).
• Make sure the hood is level and,if necessary,
adjust by acting upon the adjustment screws
(fig.6).
Wall unit installation
• Using the cardboard template.
• Mark and drill the bottom of the wall unit,(see
instructions on the template).
• Fasten the hood from inside the unit using
four screws 4,2 x 44,4 (supplied)(fig.7).
• For suction hoods,the wall unit must be drilled
to allow for the air discharge duct.
• Filter hoods do not require this type of
drilling operation since the air is recycled
into the room through vents situated on the
front of the hood.

Connecting suction or filter hoods
Connecting suction hoods
(Air is discharged into the atmosphere)
• The hood comes with two air outlets,a plastic cover
fitted in the rear hole and a flange to be fitted according
to the solution chosen:top discharge (fig.8),rear
discharge (fig.9).
• In case of installation with rear discharge,fit the plastic
cover in the top hole and the flange in the rear hole.
• Using a pipe Ø 100 o 120 mm,connect the air discharge
flange to the external discharge duct.
• Open the grid panel by pressing inwards on the knobs
(fig.10),check that the lever (hood with one motor)or
the handle (hood with two motors) points to the ducting
mode position (fig.11).
• Remove the charcoal filter,if any,by turning the handle
anti-clockwise.
Connecting filter hoods
(Air is filtered and recirculated inside the room)
• Open the grid panel.
• Check that the lever (hood with one motor)or the handle
(hood with two motors)points to the filter mode position
(fig.11)
• Insert the charcoal filter.
Electrical connection and
working test
• Before connecting to the mains supply
ensure that the mains voltage corresponds
with the voltage on the rating plate inside
the hood.
• Connect the cooker hood to the mains via
a bipolar switch which has 3mm clearance
between the contacts.
• The device does not require earthing,as it
is double-insulated.
• Once the electrical
connection has been
completed,check
that the worktop
illumination, motor
and speeds work
properly.

USE
SAFETY WARNINGS
• Before connecting to the mains supply ensure that the mains voltage corresponds
with the voltage on the rating plate inside the hood.
• The grease filters and the charcoal filters should be cleaned or replaced as
recommended by the manufacturer or more frequently if the hood is used consistently
(more than 4 hours per day).
• When using a gas hob in connection with the cooker hood never leave the burners of
the hob uncovered while the hood is in use or when the pans have been removed.
Switch off the gas before removing the pan or for just short periods and never leave
the hob unattended.
• Always ensure that the appliance is kept at the correct intensity to prevent the flame
from licking round from the bottom of the pan; this will save energy and will avoid a
dangerous concentration of heat.
• Always ensure that the appliance is used in accordance with the manufacturer’s
instructions for the removal of contaminated odours during cooking.
Instruction for Use
Control panel (3 switches) (fig. 12a)
SWITCH L = controls the worktop illumination
SWITCH M = switches the motor on or off
SWITCH V = controls the fan speed
Control panel (2 switches) (fig. 12b)
SWITCH L = controls the worktop illumination
SWITCH M = controls the power to the motor and the fan speed
Working speeds:
Position 1 = low speed, should be selected when simmering or using only one pan: the
noise level is kept to the minimum.
Position 2 = medium speed, should be selected for normal cooking. This speed offers
the best ratio between air capacity and noise level.
Position 3 = top speed, should be selected when frying or cooking food with strong odours,
even for a long period.

MAINTENANCE
Regular maintenance will ensure good performance and extend the working life of the
hood. Special attention should be taken to the grease filters and, for the filter hoods only,
to the charcoal filters.
Synthetic grease filters
1 - They cannot be washed and
should be replaced every two
months on average. If the
filter is equipped with
chemical indicators of
saturation, replace it when
the visible red-coloured dots
show all over the surface.
2 - Replacement
Open the grid panel, remove
the steel-wire clips and
replace the grease filter (fig.
13). Close the grid panel.
Metal grease
filters
1 - Cleaning
These filters need to be washed with ordinary household detergent every 2 months
maximum. Thanks to their reduced dimensions, they can also be washed in the
dishwasher.
2 - Removing the filter
Open the grid panel, remove the steel wire clips and the grease filter (fig. 13). Make
sure that the filter is dry before replacing it, close the grid panel.
WARNING : Respect replacement and maintenance schedules recommended in
order to avoid fire hazards caused by over-saturated filters.
Charcoal filters
1 - How they work
Charcoal filters can absorb smells and odours until
they are saturated. They cannot be washed or recycled
and so they should be replaced at least every 4 months
or more frequently if the hood is heavily used.
2 - Replacement:
Open the grid panel, replace the charcoal filter by
turning the locking handle anti-clockwise for removing
and clockwise for replacing (fig. 14). Close the grid
panel.

Lighting
It is composed of one or two 40 W
lamps which can be reached by
removing the grid panel (Fig.15).
If the lights fail to function, check that
they are fully screwed into place. If
they have blown, they should be
replaced with similar lamps having the
same voltage and power.
Cleaning
When cleaning the hood:
- Never use a wet cloth or sponge, or
running water.
- Never use thinners or products
containing alcohol, as they might
damage the paintwork.
- Never use abrasive cleaning
materials, in particular when cleaning
stainless steel surfaces.
It is recommended to use a damp
cloth and mild liquid household
cleaner.
