FLOAT SWITCHES (CONTROL BOX)

For special remote pumping applications of the submersible pump, a control box (Models CB6 or CB200) is required. These
water resistant control boxes provides watertight housing and glands to prevent water from leaking into the box, and a float
switch interface. Both control boxes will require the use of two SW-1WOPA float switches, no plug, bare wires for direct
connection to the control box. See Figures 9, 10 and 11 for control box connections.
