MOUNTING FLOAT SWITCHES
Sump Watch is equipped with two (2) float sensors, shown at right. Positioning and installation of
the float switches is application dependent and will require consideration by you, the user.
The LEVEL sensor on the longer (15 Foot) cable labeled “L” is the sensor that controls the pump.
The ALARM sensor labeled (A) on the short (10 foot) cable is for the high water alarm. The ALARM
(A) sensor is mounted ABOVE the LEVEL (L) sensor. For longer cord units the cables may be the
same length.
Both Float sensors will need to be positioned in the sump and TESTED in their final locations in order to fill their intended function.
Each sensor contains a counterweight positioned on the cord. The sensors require a range of motion relative to the counterweight.
When the float switch drifts above the counterweight, the switch closes, and when it returns below the counterweight the switch
will open. The switches must be free to rise and fall without interference. The counterweights on the float switches can be moved up
and down the cable as required. A minimum of 3” of cable is required between the float and counterweight. IT MAY BE NECESSARY
TO ANCHOR THE CABLES AT THE TOP OF THE SUMP TO CONTROL THE SENSOR HEIGHTS.
