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

 

not use 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.
