5.3 Filter Cleaning
In order to ensure maximum suction performance, the suction unit has a device for cleaning the fine filter
unit� The cleaning takes approx� 8 sec�
The cleaning is carried out:
• Automatically:
- After the unit is switched on;
- With insufficient suction power (flow velocity falls below an internal limit value);
- If the unit has been operated for more than 8 hours (turbine running time) without switching it off;
• Manually, e�g� before removing the dust drawer to empty it (see chapter 6�2)�
5.3.1 Automatic Filter Cleaning
♦ Suction turbine is stopped�
♦ The symbol "dust drawer" blinks�
♦ "CLEAn" is shown in the display�
♦ An acoustic signal indicates the cleaning is about to commence�
♦ The filter cleaning is performed.
♦ Suction turbine starts again�
After an automatic filter cleaning, in case of a renewed drop of the flow velocity, the next filter
cleaning will be performed only after 2 hours of turbine running time.
5.3.2 Manual Filter Cleaning

5.4 Setting the Parameter

The setting of various parameters and the execution of a self-diagnosis are carried out in the program-
