FLOAT SWITCHES (CONTROL BOX)

For special remote pumping applications of the submersible pump, a control box (Model CB3) is required. This water
resistant control box (Figure 10) provides watertight housing and glands to prevent water from leaking into the box, and a
float switch interface. The CB3 control box will require the use of two SW-1WOPA float switches, no plug, bare wires for
direct connection to the control box. Reference Figure 23 for a schematic reprensentation of the control box.
