SAFETY INSTRUCTIONS
This equipment should be installed and serviced by technically qualified personnel who are familiar
with the correct selection and use of appropriate tools, equipment, and procedures. Failure to comply
with national and local electrical and plumbing codes and within Little Giant recommendations may
result in electrical shock or fire hazard, unsatisfactory performance, or equipment failure.
Know the product's application, limitations, and potential hazards. Read and follow instructions care-
fully to avoid injury and property damage. Do not disassemble or repair unit unless described in this
manual.
Failure to follow installation or operation procedures and all applicable codes may result in the follow-
ing hazards:
Risk of death, personal injury, or property damage due to explosion,
fire, or electric shock.
• Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc.
• Do not use in explosive atmospheres or hazardous locations as classified by the NEC, ANSI/NFPA70.
• Do not handle a pump or pump motor with wet hands or when standing on a wet or damp surface, or in water.
• When a pump is in its application, do not touch the motor, pipes, or water until the unit is unplugged or electri-
cally disconnected.
• If the power disconnect is out of sight, lock it in the open position and tag it to prevent unexpected application of
power.
Risk of severe injury or death by electrical shock.
• To reduce risk of electrical shock, disconnect power before working on or around the system.
• Check local electrical and building codes before installation. The installation must be in accordance with their
regulations as well as the most recent National Electrical Code (NEC) and the Occupational Safety and Health Act
(OSHA).
• Wire pump system for correct voltage.
• Be certain that this pump is connected to a circuit equipped with a ground fault circuit interrupter (GFCI) device if
required by code.
• Check electrical outlets with a circuit analyzer to ensure power, neutral, and ground wires are properly con-
nected.
• Some pumps are supplied with a grounding conductor and grounding-type attachment plug. To reduce risk of
electric shock, be certain that it is connected only to a properly grounded grounding-type receptacle. Do not
remove the third prong from the plug. The third prong is to ground the pump to help prevent possible electric
shock hazard.
• Some pumps are supplied with lead wires and are intended to be hardwired using a junction box or other
approved enclosure. The pumps include a grounding connector. To reduce risk of electric shock, be certain that it
is properly connected to ground.
• In a 230 V direct wire installation, one side of the line going to the pump is always electrically energized, regard-
less of whether the liquid level control switch is open or closed. To avoid hazards when installing or servicing,
install a double-pole disconnect near the pump installation.
• Do not use the power cord for lifting the pump.
• Do not use an extension cord.
