Safety Precautions

RISK OF ELECTRIC SHOCK
 Accidental contact with electrically live parts, items, fluid, or
water can cause serious injury or death.
 Always disconnect pump(s) from power source(s) before
handling or making any adjustments to either the pump(s),
the pump system, or the control panel.
 All installation and maintenance of pumps, controls,
protection devices, and general wiring shall be done by
qualified personnel.
 All electrical and safety practices shall be in accordance with
the National Electrical Code
Health Administration, or applicable local codes and
ordinances.
 Do not remove cord and strain relief, and do not connect
conduit to pump.
 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 lift or carry a pump or a float assembly 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.
RISK OF FIRE
 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.
 This product requires a separate, properly fused and
grounded branch circuit, sized for the voltage and amperage
requirements of the pump, as noted on the nameplate.
Overloaded branch circuit wires will get very hot and can
catch on fire.

 Do not use this product with or near flammable or explosive
fluids such as gasoline, fuel oil, kerosene, etc. If rotating
elements inside pump strike any foreign object, sparks may
occur. Sparks could ignite flammable liquids.
 Hazardous locations contain explosive gases that can be
detonated by sparking or electric shock.
 All terminations and penetrations of conduit or cable shall be
done using approved materials and methods intended for
use to mitigate the potential for explosion.
 When working in a hazardous location, all precautions to
minimize ignition sources such as spark and flame should be
taken to limit the potential for fire or explosion.
 Sewage and effluent systems produce and may contain
flammable and explosive gases. Prevent introduction of
foreign objects into basin as sparks could ignite these gases.
Exercise caution using tools and do not use electronic devices
or have live, exposed electrical circuits in or around basins,
open covers and vents.
 Use only non-sparking tools and components in and around
basins, open covers and vents. Do not use electronic devices
that are not rated for use in hazardous locations or have live,
exposed electrical circuits in or around basins, open covers
and vents. Sewage and effluent systems produce and may
contain flammable and explosive gases and sparks could
ignite these gases.
RISK OF SERIOUS INJURY OR DEATH
 All electrical and motor repairs and service must be
performed by a repair facility approved by Liberty Pumps and
certified to work on explosion-proof motor enclosures.
 Do not remove power supply or control cord. All electrical
and motor repairs and service must be performed by the
factory or a repair facility approved by Liberty Pumps and
certified to work on explosion-proof motor enclosures.
 Refer to Chapter 5 of the National Electric Code
applicable local codes and ordinances for all electrical and
wiring requirements in hazardous locations.
 Float switches must be connected to an intrinsically safe
circuit in the control panel as per the requirements of
Chapter 5 of the National Electric Code®.
 All personnel shall be trained and qualified for safe work
practices and procedures.
 All installations shall be in compliance with all applicable
Federal, State, and Local codes and ordinances for hazardous
locations.
 All electrical terminations shall be made according to Federal,
State, and Local codes for hazardous or classified locations.
 Conduit, junction boxes, and associated components shall be
approved for use with hazardous locations and installed
according to specifications.
 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.
