Operating modes
2
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 no activated carbon filter is installed,
it is not possible to bind the odorous
substances in the cooking vapours.
Exhaust-air mode:
❑The extractor-hood fan extracts the kit-
chen vapours and conveys them
through the grease filter into the atmos-
phere.
❑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).
Activated carbon filters can be
purchased from specialist outlets
(see Optional accessories on the last
page).
❑The ventilator fan draws the vapours
produced during cooking into the
extractor hood, where they pass
through the grease filter and the activa-
ted carbon filter before the clean air is
discharged back into the kitchen.
❑The grease filter absorbs the grease
contained in the vapours produced
during cooking.
❑The activated carbon filter absorbs any
odorous substances.
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 boi-
lers) care must be taken to ensure that
there is an adequate supply of fresh
air which will be needed by the burner
for combustion.

Various types of grease filter can be
used to absorb the grease contained in
the vapours produced during cooking.
Fleece grease filter
The filter mat is made from material that is
itself virtually non-inflammable.
Caution:
As it becomes more and more saturated
with grease however, the filter becomes
increasingly inflammable. The efficiency of
the extractor hood can also be adversely
affected.
Important:
Renewing the fleece filter at appropriate
intervals prevents the possibility of it
catching fire as a result of a build-up of
heat, such as occurs when deep-fat frying
or roasting is taking place.
Renewing the fleece filter:
❑Under normal operating conditions
(1 to 2 hours per day), the fleece filter
will require replacing after 8 to 10
weeks. Printed fleece filters must be
renewed no later than when the colou-
red printing has started to fade.
❑Use only original replacement filters.
In so doing you will ensure that safety
regulations are upheld and the extractor
hood performs as effectively as possi-
ble.
Disposing of the old fleece grease filter:
Fleece grease filters do not contain any
pollutants. They can be composted and
disposed of as biodegradable waste.

4.Install the filter frame in reverse sequence.
Re-attach the retaining spring.
The left and right sides of the filter
frame must lock into position!
Metal grease filter
The filter mat is made of non-combustible
metal.
Caution:
As it becomes more and more saturated
with grease, the filter also becomes
increasingly inflammable. The efficiency of
the extractor hood can also be adversely
affected.
Important:
Clean the metal grease filter at regular
intervals.
Cleaning the metal filter:
Under normal operating conditions (1 to 2
hours per day), the metal grease filter will
require cleaning after 8 to 10 weeks.
❑The filter can be cleaned in a
dishwasher.
This can however cause slight
discoloration.
Important:
Metal filters that are heavily saturated with
grease should not be cleaned at the same
time as any crockery, etc.
❑If the filter mat is going to be cleaned by
hand, soak it first of all in a hot deter-
gent solution for several hours.
Clean the filter with a brush, rinse it off
thoroughly and allow it to drip dry.
❑Use only original replacement filters.
In so doing you will be ensuring that the
extractor hood performs as effectively
as possible.

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 the combustion air
can be replenished by being able to flow
through non-closeable openings such as in
doors, windows, wall ventilation boxes, or by
alternative technical measures such as reci-
procally shutting the other device off, 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.
All legal requirements concerning the
discharge of exhaust air must be observed.
Unrestricted operation is possible if the
extractor hood is used in recirculating mode
– with activated carbon filter.
The extractor hood should be fitted with a
one-way flap for exhaust-air mode if there is
not already one installed in the exhaust-air
pipe or wall box. If a one-way flap is not
enclosed with the appliance, purchase one
from a specialist outlet (see optional acces-
sories on the last page).
Attaching the one-way flap
❑Insert the two lugs on the one-way flap
into the holes on the air-pipe connector
or air outlet and lock into position.
Before installing the one-way flap, ensu-
re that the lettering or stamp is on the out-
side.

Optimum performance of the extractor
hood:
❑Short, smooth extraction pipe.
❑As few pipe bends as possible.
❑Largest possible pipe diameter (prefera-
bly 150 mm ø) and large pipe bends.
❑Round pipes:
We recommend
for single-motor model,
inner diameter of at least 120 mm
for double-motor model.
inner diameter of at least 150 mm
❑Flat ducts must have an inner cross-
section equivalent to round pipes
which have an inner diameter of
120/150 mm.
120 mm l approx. 113 cm2
150 mm l approx. 177 cm2
❑If pipe diameters differ: use sealing
strip.
❑Ensure an adequate air supply for
exhaust-air mode.
Pipe connection

duct a performance test.
Extractor hoods with rectangular air
outlet:
❑Screw the enclosed
air-pipe connector
over the air outlet.
Recirculated
air mode
❑The air cleaned by an additional activa-
ted carbon filter is conveyed back into
the room.
❑In recirculated air mode the exhaust ope-
ning must be protected by a grille (see
optional accessories on the last page) in
order to prevent a mechanical or electri-
cal hazard.
