OWNER'S MANUAL
BSC33 & BSC50V Effluent Pumps
This submersible pump is for use in basins or lift stations and is suitable for
pumping clear water or effluent gray water with up to ⅜-inch (9.53 mm)
spherical semi-solids. Do not use the pump in applications where sewage or
any other debris (gravel, sand, floating debris, etc.), abrasives, or corrosives are
present.
The pump motor is equipped with an automatic resetting thermal protector
and may restart unexpectedly. Protector tripping indicates motor overloading
or overheating, which can be caused by application issues such as an
obstructed pump impeller, switch stuck in the ON position, pump running dry,
pump air-locked, pump short cycling, excessively high or low voltage supply, or
possibly a pump, motor, bearing, or seal that have reached the end of their use-
ful life.
This product is covered by a Limited Warranty for a period of 2 years from the date of original purchase by
the consumer. For complete warranty information, refer to www.LittleGiant.com.
