5. 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, eventually bringing about additional water damage. To minimize the potential for water damage
due to pump failure. Please carefully read the manual and follow the instructions 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
and/or property damage.
For your protection and safety, always follow these general rules with pumps:
Always disconnect the pump from its power source before installing, inspecting, maintaining, or repairing.
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. The motor has NO repairable internal parts, and disassembling may
cause water leakage or dangerous electrical wiring issues.
Do not lift pump by power cord or switch cord.
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 before servicing.
4. Release all pressure（drain all water）within system before servicing any component.
5. Secure discharge line before starting pump. An unsecured discharge line will whip, possibly causing personal injury
and/or property damage.
6. 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.
7. Check that all pipe connections are tight to minimize leaks.
8. Connect the pump DIRECTLY to a grounded, GFCI outlet.
9. 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.
10. Make certain the electrical circuit to the pump is protected by a 15 Amp or larger fuse or circuit breaker.
11. Periodically inspect the pump and system components to be sure the pump inlets are free of mud, sand, and debris.
DISCONNECT THE PUMP FROM THE POWER SUPPLY BEFORE INSPECTING.
Do not handle pump or pump motor with wet hands or when standing on wet or damp surface, or in water.
12.
13. Wear safety glasses at all times when working with pumps.
14. Follow all electrical and safety codes, particularly the National Electrical Code (NEC) and in the workplace, the
Occupational Safety and Health Act (OSHA).
15. 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
