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.

D

When 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 air­intake/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.

Instructions for use:

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.

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
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.

2. Clean the filters.

3. Insert the clean filters back into the

hood.

Removing and inserting the metal grease
filters:

Warning: The halogen bulbs must be

switched off and cool.

1. Press the catch on the grease filters
inwards and fold the filters down.
At the same time take hold of the under­side of the grease filters with your other
hand.

8

Filters and maintenance

Activated carbon filter:

For neutralizing odours in recirculating
mode.

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.

3. Engage the catch.

4. Insert the metal grease filters (see

"Removing and inserting the metal
grease filters").

Replacing the activated carbon filter:

❑ During normal operation (1 to 2 hours

per day) the activated carbon filters
should be replaced approximately 2 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.

Installation and removal:
Warning: The halogen bulbs must be

switched off and cool.

1. Remove the metal-mesh filters
(see "Removing and inserting the metal­mesh grease filters").

2. Insert the activated carbon filter.

Cleaning and care

Isolate the extractor hood by pulling out
the mains plug or switching off the fuse.

 Do not clean the extractor hood with

abrasive sponges or with cleaning agents
which contain sand, soda, acid or chlorine!

❑ Clean the extractor hood with a hot soap

solution or a mild window cleaner.

❑ Do not scrape off dried-on dirt but wipe

off with a damp cloth.

❑ When cleaning the grease filters, remove

grease deposits from accessible parts of
the housing. This prevents the risk of fire
and ensures that the extractor hood
continues operating at maximum
efficiency.

 Clean the operating buttons with a mild

soapy solution and a soft, damp cloth only.
Do not use stainless-steel cleaner to clean
the operating buttons.

Stainless steel surfaces:

❑ Use a mild non-abrasive stainless steel

cleaner.

Important information

Installation Instructions:

Additional information concerning gas
cookers:

When installing gas hotplates, comply

with the relevant national statutory
regulations (e.g. in Germany: Technische
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

The extractor hood can be used in

exhaust air or circulating air mode.

The width of the extractor hood must

correspond to the width of the cooking
area.

Always mount the extractor hood over

the centre of the hob.

Minimum distance between electric

hob and bottom edge of extractor hood:
550 mm, Fig. 1.

The extractor hood must not be

installed over a solid fuel cooker – a
potential fire hazard (e.g. flying sparks) –
unless the cooker features a closed,
non-removable cover and all national
regulations are observed.

The smaller the gap between the

extractor hood and hotplates, the greater
the likelihood that droplets will form on the
underside of the extractor hood.

12

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.

D

Exhaust 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.

D

When 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 air­intake/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.

For optimum extractor hood efficiency:

❑

Short, smooth air exhaust pipe.

❑

As few bends in the pipe as possible.

❑

Diameter of pipe to be as large as
possible and no tight bends in pipe.

If long, rough exhaust-air pipes,
many pipe bends or smaller pipe
diameters are used, the air extraction
rate will no longer be at an optimum
level and there will be an increase in
noise.

The manufacturer of the

extractor hoods accepts no liability
for complaints which can be
attributed to the design and layout of
the pipework.

❑

Round pipes:

We recommend
Internal diameter: 150 mm (at least
120 mm).

❑

Flat ducts must have an internal cross­section that equates to that of round
pipes.

There should be no sharp bends.
