Safety Precautions

RISK OF ELECTRIC SHOCK
WARNING
 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
Safety and 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 cord from the environment.
Unprotected power and switch cords can allow water
to wick through ends into pump or switch housings,
causing surroundings to become energized.

RISK OF FIRE
WARNING
 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.
 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. Use caution using tools and do not use
electronic devices or have live, exposed electrical
circuits in and around basins, open covers and vents.
 These pumps are not to be installed in locations
classified as hazardous in accordance with the National
®
Electric Code , ANSI/NFPA 70.
RISK OF SERIOUS INJURY OR DEATH
WARNING
 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.
 Vent basin in accordance with local code. Proper
venting of sewer gases alleviates poisonous gas
buildup and reduces the risk of explosion and fire from
these flammable gases.
 Wear adequate Personal Protective Equipment when
working on pumps or piping that have been exposed
to wastewater. Sump and sewage pumps often handle
materials which can transmit illness or disease upon
contact with skin and other tissues.
 Do not enter a pump basin after it has been used.
Sewage and effluent can emit several gases which are
poisonous.
