Use of the cooker bonnet as an exhaust bonnet (with exhaust air to the
outside)
If the cooker bonnet is equipped with an activated carbon filter at the factory,
this must be removed. It is only useful if you operate your cooker bonnet in
recirculation mode.
Conversion of the cooker hood into a recirculation hood
If you want to use a suitably equipped cooker bonnet as a recirculation bonnet,
you must fit the activated charcoal filter(s) to the fan motor before using the
bonnet. The activated charcoal filter(s) is/are included with some models.
Otherwise, you must obtain the activated charcoal filter(s) from the supplier of
your cooker bonnet.
Important notes for the installation of exhaust air pipes

Air outlet to the outside
The following rules must be strictly observed to guarantee optimum air extraction:
Failure to follow these instructions will reduce the performance and increase the
noise level of the cooker hood.
• Lay the exhaust pipe as short and straight as possible.
• To avoid excessive noise or reduced extraction performance, the diameter of
the exhaust pipe should not be smaller than 150 mm.
• Do not use a smaller exhaust pipe and do not constrict it.
• Only use or shape bends with a large radius. Small radius bends reduce the
extraction performance of the bonnet.
• Only use smooth piping or flexible hoses made of non-flammable materials as
exhaust air pipes.
• When using flexible pipes, the pipe must always be installed tightly in order to
minimise pressure loss.
• If the exhaust air pipe is laid horizontally, a minimum gradient of 1 cm
per metre or an angle of inclination of 2° must be maintained. Otherwise
condensation water could run into the motor of the cooker bonnet.
