Electrical Service and Operation

RISK OF ELECTRIC SHOCK
WARNING
 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.
 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.
 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.
 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
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 or 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.
8337000G
 Do not modify the pump/pump system in any way.
 All pump/pump system installations shall be in compliance
 Vent basin in accordance with local code. Proper venting of
 Wear adequate Personal Protective Equipment when working
 Do not remove any tags or labels from the pump or its cord.
 Keep clear of suction and discharge openings. To prevent
P680-Series System Controller
P680-Series systems are connected to a controller that monitors
the operation of the pumps. The controller will automatically
alternate between the two pumps each cycle to maintain equal
wear. It will also monitor for high water conditions and alarms if
necessary. The controller has visual indicators that show the
operation of the sump as well as operator controls to test
functionality. The controller will also identify a non-functioning
component. For complete operation, refer to the user manual for
the controller.
Liberty Pumps offers both an indoor (Figure 9) and outdoor
(Figure 10) version of the controller.
Note: The cord ends must be removed in order to wire the
outdoor controller.
