Boost mode
In case of heavy air pollution, the boost mode can be activated over an
adjustable time. The time period can be set using the arrow keys (item 3).
NOTE
The extraction capacity depends on the saturation of the filter media. If
an increase in performance is barely noticeable in boost mode, it may be
necessary to change the filter media.
4. Menu item – Maintenance
If maintenance has been carried out by the manufacturer's service
department, the hour counter can be reset to the initial value until the next
maintenance.
This requires the entry of an enable PIN. This can only be entered by the
manufacturer's service department.
