y
The device must remain accessible at all times for
maintenance work (e. g. with a removable rear panel or
service cover). The space must be sufficiently large to
allow for removal of the recirculated air filter.
y
During recirculated air mode sufficiently large ventilation
slots must be available for the ventilation.
y
The air flowing out must be able to dissipate unimpeded.
y
If necessary for the installation, only use suitable hob
protection grates or hob covers.
☞
Please consult your dealer or customer services.
Country-specific, legal provisions must be observed.
3.3
Requirements for individual operating modes
Depending on the operating mode, further accessories are
required:
3.3.1
Requirements for recirculated air mode
y
Recirculating air kit DL BUF or DL BUR.
y
Recirculated air fan on the fan outlet.
y
Minimum size of the fan outlet opening in the lower
cabinet 2 x 250 cm
2
.
y
Filter filling freely accessible for changing.
y
The air escaping from the recirculation filter must be
fed out of the cabinet in a closed system (“guided
recirculating air”).
It is only possible to dispense with a guided recirculating
air system if cabinet or structural building damage due
to moisture (e.g. caused by condensate) can be fully
excluded.
y
The installation variant with recirculated air filter permalyt
(recirculating air kit DL BUR) requires an additional 230 V
socket.
3.3.2
Requirements for extracted air mode
y
Exhaust air kit DL.
y
Exhaust air ducting at the fan outlet.
D
“3.4 Requirements for the exhaust air ducting
(only for extracted air mode)” (page 11).
y
Diameter of the exhaust air ducting at least 150 mm
(corresponds to a surface area of approx. 177 cm
2
).
y
Adequate fresh air supply is assured through the
installation of the necessary accessories.
y
Window contact switch BKA DL.
y
Wall box.
3.4
Requirements for the exhaust air ducting
(only for extracted air mode)
D
WARNING!
Fire hazard and asphyxiation hazard due to improper
installation!
When using the exhaust air ducting with other devices
or when connecting an active exhaust air channel (e.g.
chimney), gases or smoke can be drawn into the room.
☞
Make sure that the requirements for the exhaust air
ducting are complied with.
y
The exhaust air ducting is used exclusively by this device.
y
The exhaust air ducting is made of non-combustible
material in accordance with DIN 4102 class 1.
y
When using a chimney as the exhaust air duct:
y
The chimney must not be used by other devices.
y
The extracted air must be introduced into the
chimney using a 90° bend pointing upwards.
y
Approval by a master chimney sweep.
y
When routing the exhaust air ducting through the roof or
the outside wall:
y
The cross-section must not be smaller than that of the
fan outlet.
y
Installation of condensed water collector in the
exhaust air ducting in order to prevent water damage
inside the device. The condensed water collector must
be adequately dimensioned.
The cross-section, length, type and course of the exhaust
pipe affect the extraction efficiency. Changing the direction
of the air too severely leads to a loss of performance and to
noise.
To optimise the device performance:
y
Keep the exhaust air ducting as short as possible (no
longer than 4 m) and route it directly to the outside.
y
The stipulated cross-section of the exhaust air ducting is
complied with.
D
“3.3 Requirements for individual operating modes”
(page 11).
y
Exclusive use of ducts and bends with smooth inner
surfaces.
In order to avoid turbulence or backpressure in the
transported air - do not use:
y
Spiral hoses.
y
Flexible tubes.
y
Flat deflection pieces.
y
Sharp-edged exhaust air channels.
The exhaust air ducting must be in place before installing
the device.
