6.3 Change Fine Filter
As a fine filter, it contains a two-stage filter system category M. This ensures a high level of health protec-
tion and a long service life for the extraction system�
To ensure this function, please note the following:
► If the suction power is no longer sufficient in spite of a filter cleaning, the fine filter must be
changed.
► In general, the fine filter should be changed every 2 years.
Do not clean the fine filter manually (e.g. with compressed air, brush, water, etc.), as this leads to
damage of the filter material!
When installing the fine filter please ensure that it is positioned correctly, otherwise leakages may result.
See the assembly instruction at the end of the instruction manual, which is also attached to the new fine
filter.
