ST-1500 SERIES SUB. PUMP — FLOAT SWITCH (CONTROL BOX)

Control Box (CB3)

For special remote pumping applications of the submersible pump, a control box (Model CB3) may be required.This water resistant control box provides watertight housing and glands to prevent water from leaking into the box, and a float switch interface. When using the CB3 control box, only the SW-1WOP float switch (2) can be used (no plug, bare wires).Shown below (Figure 7) is a wiring layout of the CB3 control box. See page 22 for a wiring diagram of the control box.
