Description
Recirculated air mode
The device intakes room air, filters the room air and
returns the cleaned room air into the room.
Cleaning is carried out in several cleaning stages.
The first cleaning stage removes e.g. grease and
air particles from the intaken room air. The next
cleaning stage filters light, flying particles (e.g. fluff)
from the intaken room air. The filter filling in the
recirculating air filter neutralises existing odour
contents. The odour-free, cleaned room air is
returned into the room.
berbel extractor hoods are developed according to
the state-of-the-art. They meet the prescribed safety
regulations and are intended for domestic use.
The filter filling must be replaced at regular
intervals.

devices which are dependent on the
room air, such as e.g. a gas cooker,
chimney or gas heater, make sure
that no gases or exhaust gases are
drawn into the room.
¾Ensure an adequate fresh air supply
in the dwelling.
¾Make sure that the legally prescribed
requirements of your Federal state's
regulations pertaining to fireplaces
(FeuV)) are adhered to.
¾Make sure that the permit required
from the master chimney sweep to
operate the extractor hood is
available.
Measures for an adequate fresh air supply:
•Operate the device only with a window contact
switch connected.
•Open the windows.
•Open the doors.
•Install a berbel wall box BMK.
•Make sure that the open fireplace's prescribed
forced ventilation functions.
WARNING
Danger of suffocation due to a lack of
oxygen on operation of the device.
¾Ensure an adequate fresh air supply
in the dwelling.
¾Make sure that the device is
connected to a window contact
switch to ensure hazard-free
operation.
¾Make sure that the country-specific,
legally prescribed regulations (in
Germany e.g. the requirements of
your Federal state's regulations
pertaining to fireplaces (FeuV)) are
adhered to.
If an extractor hood and a fireplace which is
dependent on the room air (e.g. gas-, oil- or coal-
fired heaters, chimneys, hot water boilers, gas hobs
or gas ovens) are operated at the same time, the
following prerequisites must be met:
¾Your master chimney sweep has approved the
installation of the extractor hood beforehand.
¾Installation must be carried out under adherence
to the country-specific regulations (e.g. the
regulations pertaining to fireplaces (FeuV)).
¾Installation must be carried out under adherence
to the official and legal regulations (e.g. state
building ordinances).
In air extraction mode, the device intakes room air
and conducts it outside via the outgoing air line.
The device is only able to conduct the volume of air
away which flows into the kitchen as supply air.
The cross-section, length, type and routing of the
outgoing air line extensively influence the extraction
efficiency of an extractor hood.
Power losses and noises arise e.g. due to air which
is diverted abruptly in the outgoing air line.

Air extraction mode
15
The device's optimal output is obtained if, when
installing the outgoing air line, you ensure that:
•the outgoing air line is as short and direct as
possible
•the transported room air is able to flow through
the outgoing air line without vortices and back
pressure
•the prescribed outgoing air line cross-section is
adhered to
•the recommended characteristics of the outgoing
air line are adhered to throughout.
The following section explains which requirements
and characteristics the outgoing air line has to
meet.
Outgoing air in the separate outgoing
air duct
DANGER
Danger of suffocation due to smoke or
exhaust gases.
¾Make sure that the outgoing air duct
which is used is exclusively intended
for operating an extractor hood.
¾Make sure that the outgoing air duct
is only used by this device. On
connection of the device to an active
outgoing air duct, such as e.g. a
ventilation shaft or chimney, gases
or exhaust gases may be drawn into
the room.
DANGER
Fire hazard due to combustible
outgoing air line.
If combustible outgoing air lines are
routed through a second room or attic,
fire may spread to other rooms.
¾Make sure that the outgoing air line
consists of non-combustible material
in accordance with
DIN 4102 Class A1.
The extracted room air must only be conducted
outside via a separate outgoing air duct intended for
this purpose.
¾Make sure that the outgoing air duct which is used
is only used as an outgoing air line by the device.
Optimising the outgoing air line
Conducting the room air away directly
Conduct the extracted room air outside directly and
over the shortest route. Long routes generate
additional, undesired air resistance.
¾Make sure that the outgoing air line which leads
outside is as direct and short as possible.
Using pipes with low air resistance
Exclusively use pipes with a smooth inner surface.
These pipes offer low air resistance.
Avoid the installation of:
•Spiral hoses
•Flexible pipes
•Flat diverters.
These types of pipe have high air resistance and
reduce the extractor hood's output.

Air extraction mode
16
¾Make sure that the outgoing air line has a smooth
inner surface.
Exclusively use bends with optimised air ducting
and a smooth inner surface. These bends offer low
air resistance.
Avoid the installation of bends with sharp-edged air
ducting.
These bends have high air resistance and generate
noises. These bends reduce the extractor hood's
output.
¾Make sure that bends in the outgoing air line have
a smooth inner surface and that air ducting is
optimised.
Using the most favourable cross-section
The minimum outgoing air line cross-section is
125 mm in the case of 125 mm systems (BEH 60 N
and BEH 60 O) and 150 mm in the case of 150 mm
systems (all other berbel extractor hoods).
Each reduction of the outgoing air line generates
undesired air resistance, reduces output and
causes noises.
Avoid:
•Outgoing air lines with small diameters
•Sharp-edged flat outgoing air ducts
•Conventional wall boxes
These have high air resistance and generate
noises. They reduce the extractor hood's output.
¾Make sure that the outgoing air line's minimum
cross-section is not less than the cross-section of
the fan outlet.
Outgoing air line through the old chimney
DANGER
Danger of suffocation due to smoke or
exhaust gases.
¾A master chimney sweep must
approve the chimney as an outgoing
air line prior to the installation of the
extractor hood.
DANGER
Fire hazard due to combustible
outgoing air line.
If combustible outgoing air lines are
routed through a second room or attic,
fire may spread to other rooms.
¾Make sure that the outgoing air line
consists of non-combustible material
in accordance with
DIN 4102 Class A1.
If you use a chimney as an outgoing air line,
increased air resistance must be anticipated
depending on the length of the chimney.
The extracted air must be introduced into the
chimney using a bend which is bent upwards at an
angle of 90°. This avoids any possible back
pressure.

Air extraction mode
17
¾Make sure that the connection in the chimney is
carried out using a bend which is bent upwards at
an angle of 90°.
Outgoing air line through the roof
DANGER
Fire hazard due to combustible
outgoing air line.
If combustible outgoing air lines are
routed through a second room or attic,
fire may spread to other rooms.
¾Make sure that the outgoing air line
consists of non-combustible material
in accordance with
DIN 4102 Class A1.
ATTENTION
Water damage to the device due to the
absence of a moisture condensate
collector.
¾Install a moisture condensate
collector in the outgoing air line.
If the outgoing air line is routed through the roof,
you must ensure that:
•the cross-section of the roof passage is no less
than that of the fan outlet
•the roof passage does not reduce the cross-
section of the outgoing air line
•a moisture condensate collector is integrated into
the outgoing air line.
Outgoing air line through an exterior wall
DANGER
Fire hazard due to combustible
outgoing air line.
If combustible outgoing air lines are
routed through a second room or attic,
fire may spread to other rooms.
¾Make sure that the outgoing air line
consists of non-combustible material
in accordance with
DIN 4102 Class A1.
If the outgoing air line is routed through the exterior
wall, you must ensure that:
•the cross-section of the outgoing air line is no less
than that of the fan outlet
•the wall passage does not reduce the cross-
section of the outgoing air line.
The wall box must meet the following requirements:
•The cross-section of the fan outlet must not be
reduced in the wall box.
•The louvered cover of the wall box must ventilate
over a wide area.

Air extraction mode
18
Make sure that
•the slats of the louvered cover of the wall box are
not narrow and thick
•the slats of the louvered cover of the wall box are
not positioned sharply downwards.
•no insect screen is installed in the wall box. Insect
screens impair the cross-section of the outgoing
air line completely.
¾Use only flow-optimised wall boxes (e.g. BMK-
F/L).
