Operating Instructions
Appliance description Operating modes
Exhaust-air mode:
❑The extractor-hood fan extracts the
kitchen vapours and conveys them
through the grease filter into the
atmosphere.
❑The grease filter absorbs the solid
particles in the kitchen vapours.
❑The kitchen is kept almost free of grease
and odours.
Circulating-air mode:
❑An activated carbon filter must be fitted
for this operating mode (see Filters and
maintenance).
The complete installation set and
replacement filters can be obtained from
specialist outlets.
❑The extractor-hood fan extracts the
kitchen vapours which are purified in the
grease filter and activated carbon filter
and then conveyed back into the kitchen.
❑The grease filter absorbs the grease
particles in the kitchen vapours.
❑The activated carbon filter binds the
odorous substances.
If no activated carbon filter is
installed, it is not possible to bind the
odorous substances in the cooking
vapours.

Gas stoves and electric stoves
Do not use a gas hob with all the stoves
on and top-powered for more than 15
minutes, otherwise the surface of the cooker
hood might risk overheating, thus causing
burns in case of contact with the hood.
Furthermore the cooker hood might get
damaged.
In case more than 3 gas stoves are used,
the cooker hood must be used at top power.
❑NB: a big stove having power higher than
5 KW (type WOK) corresponds to 2
standard stoves.
❑Never use the gas stoves without any
pots. Adjust the flame so that it does not
exceed the perimeter of the pot.
Do not use or leave the hood without the
lamp correctly mounted because of the
possible risk of electric shocks.
We decline any responsibility for any
problems, damage or fires caused to the

Operating procedure
The most effective method of removing
vapours produced during cooking is to:
❑Switch the ventilator ON as soon as you
begin cooking.
❑Switch the ventilator OFF a few minutes
after you have finished cooking.
Switching ON:
❑Slide the right slide switch to the desired
fan setting.
Switching OFF:
❑Slide the right slide switch back to 0.
Lighting:
❑The light can be switched on at any time,
even though the fan is switched off.
Filters and maintenance
Grease filters:
Metal filters are used to trap the greasy
element of the vapours that develop during
cooking.
The filter mats are made from
noncombustible metal.
Caution:
As the filter becomes more and more
saturated with grease, not only does the risk
of it catching fire increase but the efficiency
of the extractor hood can also be adversely
affected.
Important:
By cleaning the metal grease filters at
appropriate intervals, the possibility of them
catching fire as a result of a build-up of heat
such as occurs when deep-fat frying or
roasting is taking place, is reduced.
Cleaning the metal grease filters:
❑In normal operation (1 to 2 hours daily),
the metal grease filter must be cleaned
after 8 to 10 weeks.
❑The filters can be cleaned in a
dishwasher. It is however possible that
they will become slightly discoloured.
❑The filter must be placed loosely, and
NOT wedged, in the dishwasher.
Important: Metal filters that are saturated
with grease should not be washed
together with other dishes etc.
❑When cleaning the filters by hand, soak
them in hot soapy water first of all. Then
brush the filters clean, rinse them
thoroughly and leave the water to drain
off.

Caution:
As the filter becomes more and more
saturated with grease, there is an increased
risk of fire and the function of the extractor
hood may be impaired.
Important:
Change the activated carbon filter promptly
to prevent the risk of fire from the
accumulation of heat when deep-fat frying or
roasting.
