Safety Guidelines

Safety Precautions

 

Accidental contact with electrically live parts, items, fluid, or 

water can cause serious injury or death.

 

Always disconnect the pump from power source before 

attempting to service the pump. Fatal electrical shock could 

occur.

 

The pump shall be plugged into a properly fused electrical 

outlet with a ground fault circuit interrupter (GFCI) that 

conforms to current National Electric Code (NEC) and all 

applicable local codes. All wiring must be performed by 

qualified personnel.

 

All electrical and safety practices shall be in accordance with 

the National Electrical Code

®

, the Occupational Safety and 

Health Administration, or applicable local codes and 

ordinances.

 

Pump shall be properly grounded using its supplied 

grounding conductor. Do not bypass grounding wires or 

remove ground prong from attachment plugs. Failure to 

properly ground the pump system can cause all metal 

portions of the pump and its surroundings to become 

energized.

 

Do not handle or unplug the pump with wet hands, when 

standing on damp surface, or in water unless wearing 

Personal Protective Equipment.

 

Always wear dielectric rubber boots and other applicable 

Personal Protective Equipment (PPE) when water is on the 

floor and an energized pump system must be serviced, as 

submerged electrical connections can energize the water. Do 

not enter the water if the water level is higher than the PPE 

protection or if the PPE is not watertight.

 

Do not handle or unplug pump with wet hands, when 

standing on a wet/damp surface, or in water. Fatal electrical 

shock could occur.

 

Do not lift or carry the pump by its power cord. This will 

damage the power cord, and could expose the electrically live 

wires inside the power cord.

 

The electrical power supply shall be located within the length 

limitations of the pump power cord, and for below grade 

installations it shall be at least 4 ft (1.22 m) above floor level.

 

Do not use this product in applications where human contact 

with the pumped fluid is common (such as swimming pools, 

fountains, marine areas, etc.).

 

Protect the power and control cords from the environment. 

Unprotected power and control (switch) cords can allow 

water to wick through ends into pump or switch housings, 

causing surroundings to become energized.

  

 

Do not use an extension cord to power the product. 

Extension cords can overload both the product and extension 

cord supply wires. Overloaded wires will get very hot and can 

catch on fire.

 

For cord replacement: power cord must be of the same 

length and type as originally installed on the Liberty Pumps 

product. Use of incorrect cord may lead to exceeding the 

electrical rating of the cord and could result in death, serious 

injury, or other significant failure.

 

Do not use to pump flammable or explosive fluids such as 

gasoline, fuel oil, kerosene, etc. Do not use in flammable 

and/or explosive atmosphere. Sparks could ignite flammable 

liquids.

 

 

Do not modify the pump/pump system in any way. 

Modifications may affect seals, change the electrical loading 

of the pump, or damage the pump and its components.

 

All pump/pump system installations shall be in compliance 

with all applicable Federal, State, and Local codes and 

ordinances.

 

Do not use this product with flammable, explosive, or 

corrosive fluids. Do not use in a flammable and/or explosive 

atmosphere as serious injury or death could result.

 

Do not allow any person who is unqualified to have contact 

with this pump system. Any person who is unaware of the 

dangers of this pump system, or has not read this manual, 

can easily be injured by the pump system.

 

Do not allow children to play with the pump.

 

Do not remove any tags or labels from the pump or its cord.
