Mounting the KVF-F Fat Level Sensor
The sensor must be immersed a few centimeters when the liquid is at its normal
level (water zero line).
The exact immersion depth depends on
the type of grease interceptor,
■
its design,
■
its capacity
■
and the height of the maximum fat layer thickness.
■
The sensor must always be immersed in the liquid. The switching point of the
sensor is located between the insulated connecting piece and the top metal
section (see chapter 2.3).
