Automatic cleaning
Due to the build-up of debris the water level on the ScreenMatic screen also rises. When the sen-
sor in the control device comes into contact with the water, it triggers the rotational movement
of the ScreenMatic screen.
By briefly moving the ScreenMatic screen back several times a larger line of debris is formed,
which can be better removed by the stripper.
Sequence of an automatic cleaning cycle
Normal soiling
1. Contact of the sensor with water
2. Contact of the sensor with water
3. Contact of the sensor with water
4. Contact of the sensor with water
Heavy soiling or incorrectly aligned control device (per-
manently high water level on the ScreenMatic screen)
1. Contact of the sensor with water
Time-dependent cleaning
The ScreenMatic rotating screen unit executes a cleaning cycle after a set interval depending on
the ambient temperature. This ensures cleaning at regular intervals
 if the sensor is soiled or defective,
 if there is very little soiling on the screen and/or low flow rates (e.g. when the SFC of the filter
pump is activated).
