5.2 Manual cleaning
Proceed as follows Description
Press for 1 s.
The ScreenMatic screen is rotated by 1 revolution.
• Press the button again for 1 s: The rotational movement stops prematurely.
5.3 Automatic cleaning
Due to the build-up of debris the water level on the ScreenMatic screen also rises. When the sensor 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 Rotational movement of the ScreenMatic screen
Normal soiling
1. Contact of the sensor with water Brief movement backward
2. Contact of the sensor with water Brief movement backward
3. Contact of the sensor with water Brief movement backward
4. Contact of the sensor with water One rotation forward
• The debris is conveyed into the debris tray.
Heavy soiling or incorrectly aligned control device (perma-
nently high water level on the ScreenMatic screen)
1. Contact of the sensor with water Brief movement backward, then one rotation for-
ward
• The debris is conveyed into the debris tray.
5.4 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 acti-
vated).
Ambient temperature Interval Rotational movement of the ScreenMatic screen
