2. DESCRIPTION
This GP submersible sewage pump is designed for pumping sewage, effluent, wastewater or flooded water with up to
two-inch (2 inch) solids. The pump is built with overload thermal protections and auto reset. The pump is equipped
with a 10’ 3-prong grounding-type power cord and tethered float switch. This pump operates automatically. Ball
bearings on motor shafts never need lubrication.
Do not pump flammable or explosive liquids such as oil, gasoline, kerosene, ethanol, etc. Do not use in the
presence of flammable or explosive vapors. Using this pump with or near flammable liquids can cause
explosion or fire, resulting in serious personal injury or death and/or property damage.

6. GENERAL SAFETY INFORMATION
This pump is made of high-strength, corrosion-resistant materials. It will provide trouble-free service for a long time
when properly installed, maintained, and used. However, inadequate electrical power to the pump, dirt, or debris may

cause the pump to fail. To minimize the potential for water damage due to pump failure, please read the section of this
manual regarding common pump problems and remedies or call one of our pump experts at 866-945-6872.
The following are the general safety requirements. Failure to follow them could cause serious personal injury or
death and/or property damage.
For your protection and safety, always follow these general rules with pumps:
Do not lift pump by power cord or switch cord.
Always disconnect the pump from its power source before inspection.
Do not stand in water when the pump is connected.
Do not touch the pump housing while it is operating, as the pump may be HOT and can cause serious skin burns.
Do not disassemble the motor housing. This pump has NO repairable internal parts, and disassembling may cause
an oil leak or dangerous electrical wiring issues.
Additional Safety Precautions
1. Know the pump applications, limitations, and potential hazards
2. Make certain the electrical power source is adequate for the requirements of the pump.
3. ALWAYS disconnect the power to the pump and drain all water from the system before servicing.
4. Secure the pump on a solid base to keep the pump vertical and above mud and sand during operation to maximize
pumping efficiency and prevent clogging and premature pump failure.
5. Secure the discharge hose before starting the pump. Pump torque may cause an unsecured discharge hose to “whip”,
possibly causing personal injury and/or property damage.
6. Check that all hose connections are tight to minimize leaks.
7. Connect the pump DIRECTLY to a grounded, GFCI outlet
8. Extension cords may not deliver sufficient voltage to the pump motor. Extension cords present a life threatening safety
hazard if the insulation becomes damaged or the connection ends fall into water.
9. Make certain the electrical circuit to the pump is protected by a 15 Amp or larger fuse or circuit breaker.
10. Periodically inspect pump and system components, to be sure pump inlets are free of mud, sand, and debris.
DISCONNECT PUMP FROM THE POWER SUPPLY BEFORE INSPECTING.
11. Do not handle pump or pump motor with wet hands or when standing on wet or damp surface, or in water.
12. Wear safety glasses at all times when working with pumps.
13. Follow all electrical and safety codes, particularly the National Electrical Code (NEC) and in the workplace, the
Occupational Safety and Health Act (OSHA).
14. This unit is designed only for use on 115 volts (single phase), 60 Hz, and is equipped with an approved 3-conductor
cord and 3-prong grounded plug. DO NOT REMOVE THE GROUND PIN UNDER ANY CIRCUMSTANCES. The 3-prong
plug must be directly inserted into a properly installed and grounded 3-prong, grounding-type receptacle. Do
pump with a 2-prong wall outlet. Replace the 2-prong outlet with a properly grounded 3-prong receptacle (a GFCI
outlet) installed in accordance with the National Electrical Code and local codes and ordinances. All wiring should be
performed by a qualified electrician.
15. Protect the electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid kinking the cord. Do not use
damaged or worn cords.
