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

≤50 °F (≤10 °C)
50 °F ... 68 °F (10 °C ... 20 °C)
≥68 °F (≥20 °C)
