Safety Precautions - Liberty Pumps 441 Manuel D'installation

Sa f ety P r eca ut ions
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.
 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
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 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.
 Do not use metal or any other electrical conducting material
to raise the float or contact anything inside an electrically live
sump pit.

RISK OF FIRE
 Use PVC cement in a well-ventilated area away from fire or
flames. Follow the PVC cement and primer manufacturer's
instructions.
 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 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.
RISK OF SERIOUS INJURY OR DEATH
 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 allow children to play with the pump system.
 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.
 Wear adequate Personal Protective Equipment when working
on pumps or piping that have been exposed to wastewater.
Sump and sewage pumps often handle materials that can
transmit illness or disease upon contact with skin and other
tissues.
 Do not remove any tags or labels from the pump or its cord.
 Keep clear of suction and discharge openings. To prevent
injury, never insert fingers into pump while it is connected to
a power source.
 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.
 This product contains chemicals known to the State of
California to cause cancer and birth defects or other
reproductive harm. www.p65warnings.ca.gov.
