 By switching on one of the electrical appliances connected to the Quattro Control-Box.
Ƈ The letters of the opened suction channels are shown in the display.
It is possible to change the suction level and select the turbo level with and without an opened suction
channel.
When one suction channel is opened, the suction turbine with the set suction level is activated.
If multiple suction channels are opened, the extraction unit increases its performance, so that all suc-
tion points achieve their allocated set suction performance.
The suction level and the selected turbo level are automatically saved and reset when the multi
use mode is selected the next time.
