Connecting sW-1Wopa Float switches to Control
box
1. Remove the float switch input connector housing, then
route the float switch wires through the cable gland on
the control box. Attach the wires of the float switch to
the terminal block as indicated by Table 6 and Figure 8.
2. Tighten the connector housing to ensure a tight fit
between the cord and the connector body. This will
prevent the cable from pulling out of the terminal block
and also prevent moisture from entering the control box.
3. Determine the tether length of the float switch wires
then secure float switch wires to pump discharge hose.
See Figure 3 and Table 3 to determine the pumping
range.
