7.1. Cleaning the rain quantity sensor

-Depending on the location, leaves, dirt, sand and branches blown by the wind get collected in the collection funnel of the rain quantity sensor. Larger parts can block the passage. Sand can also accumulate on the pointer; large deposits of it can hamper the measurement result.

-Hence the rain quantity sensor is to be cleaned from time to time - at least once a year. The pictures shown below are a guideline for installing / dismantling.

-For cleaning the sensor, just remove the sensor housing by slightly turning it to the left.

-Further, the collection funnel can also be removed by turning it to the left.

-The rainfall sensor is now moved upward, folded towards the cable side and you can now remove the pointer.

-Clean the collection funnel, contacts, counter and the drain-hole in the housing and remove all residues.

-Place the counter back in its holder. The magnet of the counter should be on the side that faces the cable.
