Mounting the overflow sensor
If a non-electrically conductive fat layer settles on the surface, there is a risk that a
possible overflow will not be detected by the sensor. Therefore we recommend
mounting a pitot tube for overflow sensor KVF-O. This ensures that the sensor
only comes into contact with water and the overflow is detected. The following
diagram shows the composition.
