9.5 Float Switch Installation
The Float Switch bracket has a hole at one end and a slot at the other. The switch is
installed in the round hole, not the slot, as indicated in Figure 11.
(a) Install the Float Switch in the round hole at the bottom end of the Float Switch
bracket as indicated.
(b) Fit an O-ring on each side of the bracket.
(c) Mount the Float Switch so that the float is level and will rise up when fluid is
present, thereby opening the circuit which is normally closed.
(d) Fit the Float Switch bracket to the sump’s spare bolt and secure it with the
supplied nut.
(e) Secure the cable to the top end of the bracket with the cable tie through the
small hole next to the slot. The cable is connected to P31 on the Multiplexer
Board, the position of which is shown below.
(f) Secure the cables away from all belts and moving parts using cable ties.
