Mounting the KVF-O Overflow Sensor
Usually, the switching point of the sensor must be located a few centimeters
above the normal liquid level (water zero line) in a position so close to the water
zero line that the switching point is surrounded by liquid when an overflow occurs.
This occurs
n
when there is back pressure in the sewage system or
n
if the drain is blocked.
The switching point of the sensor is located between the insulated connecting
piece and the top metal section (see chapter 2.3).
