PRODUCT DESCRIPTION
This submersible pump is for use in basins or lift stations and is suitable for pumping clear water and other
non-explosive, non-corrosive liquids. Do not use the pump in applications where sewage or any other debris
(gravel, sand, floating debris, etc.), abrasives, or corrosives are present.
These products have been carefully tested, inspected, and packaged to ensure safe delivery and operation.
Please examine your pump carefully to ensure that no damage occurred during shipment. If damage has
occurred, please contact the place of purchase. They will assist you in replacement or repair, if required.
The pump motor is equipped with an automatic resetting thermal protector, and may restart unexpectedly.
Thermal Protector tripping is an indication of motor overloading or overheating, which can be caused by
application issues such as an obstructed pump impeller, float 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,
bearings, or seal that have reached the end of their useful life.

Cooling
The motor housing contains oil to cool the motor and to lubricate the bearings and seals. These pumps can
be operated with the motor housing partially exposed for extended periods of time. However, for the best
cooling and longest motor life, the liquid level being pumped should normally be above the top of the
pump housing.
