WIRING DIAGRAM FOR AUTOMATIC
OPERATION
WIRING FOR AC VOLTAGE MODEL:
Use 16 gauge stranded copper wire for lengths up to 100
feet from power source. Connect the grounded,
unswitched conductor (white) to the white motor lead.
Connect the ungrounded switched conductor (black) to
the black motor lead. This conductor should include, at
the power source, a 1.5 amp 125 volt fuse. The green
motor lead must be connected to the AC circuit ground.
MAINTENANCE
WINTER STORAGE:
When possible it is preferred that the complete pump be
removed and stored in a warm dry place. If this is not
possible the pump must be completely drained, hoses
removed and pump run until all water is expelled.
