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.
DWhen the extractor hood is operated
in exhaust-air mode simultaneously with
a different burner which also makes use
of the same chimney (such as gas, oil or
coal-fired heaters, continuous-flow heaters,
hot-water boilers) care must be taken to
ensure that there is an adequate supply
of fresh air which will be needed by the
burner for combustion.
Safe operation is possible provided that the
underpressure in the room where the
burner is installed does not exceed 4 Pa
(0.04 mbar).
Instructions for use:
Operating modes
This can be achieved if combustion air can
flow through non-lockable openings, e.g. in
doors, windows and via the air-
intake/exhaust-air wall box or by other
technical measures, such as reciprocal
interlocking, etc.
If the air intake is inadequate, there is a
risk of poisoning from combustion gases
which are drawn back into the room.
An air-intake/exhaust-air wall box by itself is
no guarantee that the limiting value will not
be exceeded.
Note: When assessing the overall
requirement, the combined ventilation
system for the entire household must be
taken into consideration. This rule does not
apply to the use of cooking appliances,
such as hobs and ovens.
Unrestricted operation is possible if the
extractor hood is used in recirculating mode
– with activated carbon filter.
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 corresponding accessory numbers
can be found at the end of these
operating instructions.
❑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.

Grease filters:
Metal filters are used to trap the greasy
element of the vapours that develop
during cooking.
The filter mats are made from non-
combustible 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.
Saturation indicator: ~
When the grease filters reach saturation
point, an acoustic signal is sounded for
6 seconds after the fan has switched off,
and an ~appears in the display. The
grease filters should be cleaned straight
away.
Cleaning the metal grease filters:
❑In normal operation (1 to 2 hours daily),
the metal grease filter must be cleaned
1 x a month.
❑The filters can be cleaned in a dish-
washer. 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.
Do not use aggressive, acidic or caustic
cleaners.
Then brush the filters clean, rinse them
thoroughly and leave the water to drain off.

Saturation indicator: b
When the activated carbon filter reaches
saturation point, an acoustic signal is
sounded for 6 seconds after the fan has
switched off, and a bappears in the
display. The activated carbon filter should
be replaced straight away.
Replacing the activated carbon filter:
❑During normal operation (1 to 2 hours
per day) the activated carbon filters
should be replaced approximately 1 x
year.
❑A replacement filter can be obtained
from any authorized dealer (see optional
accessories).
❑Use original filters only.
By doing so you will obtain maximum
performance from your extractor hood.
Disposing of the old activated carbon
filter:
❑There are no pollutants in the activated
carbon filters. They can therefore be
disposed of as part of your normal
domestic refuse.

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.
Installation and removal:
Warning: The halogen bulbs must be
switched off and cool.
1. Remove the metal-mesh filters
(see "Removing and inserting the metal-
mesh grease filters").

Regeln Gasinstallation TRGI).
Always comply with the currently valid
regulations and installation instructions
supplied by the gas appliance
manufacturer.
Only one side of the extractor hood
may be installed next to a high-sided unit
or high wall. Gap at least 50 mm.
Minimum distance on gas hotplates
between the upper edge of the trivet
and lower edge of the extractor
hood: 650 mm, Fig. 1.
Old appliances are not worthless
rubbish. Valuable raw materials can be
reclaimed by recycling old appliances.
Before disposing of your old appliance,
render it unusable.
You received your new appliance in a
protective shipping carton. All packaging
materials are environmentally friendly and
recyclable. Please contribute to a better
environment by disposing of packaging
materials in an environmentally-friendly
manner.
Please ask your dealer or inquire at your
local authority about current means of

14
Prior to installation
Exhaust-air mode
The exhaust air is discharged upwards
through a ventilation shaft or directly
through the outside wall into the open.
DExhaust air should neither be directed
into a smoke or exhaust flue that is
currently used for other purposes, nor into
a shaft that is used for ventilating rooms in
which stoves or fireplaces are also located.
Exhaust air may be discharged in
accordance with official and statutory
regulations only (e.g. national building
regulations).
Local authority regulations must be
observed when discharging air into smoke
or exhaust flues that are not otherwise in
use.
DWhen the extractor hood is operated
in exhaust-air mode simultaneously with
a different burner which also makes use
of the same chimney (such as gas, oil or
coal-fired heaters, continuous-flow heaters,
hot-water boilers) care must be taken to
ensure that there is an adequate supply
of fresh air which will be needed by the
burner for combustion.
Safe operation is possible provided that the
underpressure in the room where the
burner is installed does not exceed 4 Pa
(0.04 mbar).
This can be achieved if combustion air can
flow through non-lockable openings, e.g. in
doors, windows and via the air-
intake/exhaust-air wall box or by other
technical measures, such as reciprocal
interlocking, etc.
If the air intake is inadequate, there is a
risk of poisoning from combustion gases
which are drawn back into the room.
An air-intake/exhaust-air wall box by itself
is no guarantee that the limiting value will
not be exceeded.
Note: When assessing the overall
requirement, the combined ventilation
system for the entire household must be
taken into consideration. This rule does not
apply to the use of cooking appliances,
such as hobs and ovens.
Unrestricted operation is possible if the
extractor hood is used in recirculating
mode – with activated carbon filter.
If the exhaust air is going to be
discharged into the open, a telescopic
wall box should be fitted into the outside
wall.
