5. Turn the impeller by hand to make sure it turns freely. Set pump down so the pump and impeller
are not touching anything. Plug the unit into GFCI circuit for 10 seconds to see if the impeller
turns; a) If it is rotating and GFCI did not trip, unplug unit and install parts in reverse order in
which they were removed. b) If it does not rotate, if pump is tripping circuit breakers, or not
operating properly after cleaning, return to Little Giant Pump Company or its authorized service
center. DO NOT attempt repairs yourself.
6. Be certain power cord is in good condition and contains no nicks or cuts.
