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.
