OVERFLOW SENSOR KVF-O
Installation
3.2
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
when there is back pressure in the sewage system or
■
if the drain is blocked.
■
The switching point of the sensor is located between the insulated connecting
piece and the top metal section.
