Please keep this instruction manual for future reference
› The product may only be connected by a qualified fitter according to applicable
local regulations. The same applies for the extraction air connections. The fitter is responsible
for proper functioning at the installation site.
› On installation, observe the relevant national building regulations and the regulations of the
electricity suppliers.
› The hob fan can be operated in the extraction air and recirculation air mode.
› Lead the extracted air outside through a ventilation shaft intended for this purpose or
through the wall of the building.
› Extracted air may not be led into a smoke or exhaust gas flue which is in operation.
› A sufficient supply of inlet air must be provided if a wood, coal, gas or oil heater requiring
a chimney is operated in the environment of the hob fan, since an insufficient supply of air
results in a risk of poisoning. The safe operation of the hob extractor is guaranteed when the
negative pressure resulting from the hob extractor does not exceed 0.04mbar (4 Pa) and a
sufficient supply of inlet air can flow into the room.
› Exhaust air pipes must comply with fire class B 1 DIN 4102.
› Please make sure that the mini mum nominal width of the appliance connecting pieces is
not reduced.
› A system recommended for the airflow and compatible with the hob extractor should always
be used.
› The nominal width of the recirculation air pipe should not be less than 150mm.
› Exhaust air pipes should be as short as possible. They should not have a 90-degree angle;
instead they should have soft bends and no reductions in their cross-section.
› Never use pipes with a diameter of less than 150mm. No bends/angles may be laid 50cm
before the fan module
› Always insert a straight piece of approx. 50cm between two angles/bends.
› The cross-section of wall vents and the cut-out in the base panel should should at least
correspond to the exhaust air pipe. The outflow opening must be at least 500cm². Reduce
the height of the skirting boards or make corresponding openings.
› When installing the appliance make sure that the convection air unit is still accessible when
the kitchen has been completely installed.
› If necessary, levelling feet for the kitchen units must be moved.
NOTE:
When the convection air mode is in operation, ventilation must be sufficient in order for
the air humidity to be removed.
