INTRODUCTION

This instruction sheet provides you with the information required to safely own and operate your Little
Giant pump. Retain these instructions for future reference.
The Little Giant pump you have purchased is of the highest quality workmanship and material,
and has been engineered to give you long and reliable service. Little Giant pumps are carefully
tested, inspected, and packaged to ensure safe delivery and operation. Please examine your pump
carefully to ensure that no damage occurred during shipment. If damage has occurred, please
contact the place of purchase. They will assist you in replacement or repair, if required.
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL, OPERATE,
OR SERVICE YOUR LITTLE GIANT PUMP. KNOW THE PUMP'S APPLICATION, LIMITATIONS,
AND POTENTIAL HAZARDS. PROTECT YOURSELF AND OTHERS BY OBSERVING ALL
SAFETY INFORMATION. FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD
RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE!
SAFETY GUIDELINES
WARNING: RISK OF ELECTRIC SHOCK. This pump is supplied with a grounding conductor
and/or grounding-type attachment plug. To reduce the risk of electric shock, be certain that it is
connected to a properly grounded grounding-type receptacle.
Your 115V sewage ejector pump is equipped with a 3-prong electrical plug. The third prong is to
ground the pump to prevent possible electrical shock hazard. Do not remove the third prong from
the plug. A separate branch circuit is recommended. Do not use an extension cord.
When a pump is in a basin, etc., do not touch motor, pipes or water until unit is unplugged or
shut off. If your installation has water or moisture present, do not touch wet area until all power has
been turned off. If shut-off box is not accessible, call the electric company to shut off service to the
house, or call your local fire department for instructions. Failure to follow this warning can result
in fatal electrical shock.
The flexible PVC jacketed cord assembly mounted to the pump must not be modified in any way,
with the exception of shortening the cord to fit into a control panel. Any splice between the pump
and the control panel must be made within a junction box and mounted outside of the basin, and
comply with the National Electrical Code. Do not use the power cord for lifting the pump.
The pump motor is equipped with an automatic resetting thermal protector and may restart
unexpectedly. Protector tripping is an indication of motor overloading as a result of operating the pump
at low heads (low discharge restriction), excessively high or low voltage, inadequate wiring, incorrect
motor connections, or a defective motor or pump.
1. Read all instructions and safety guidelines thoroughly. Failure to follow the guidelines and the
instructions could result in serious bodily injury and/or property damage.
2. 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 NEC, ANSI/NFPA70. FAILURE TO FOLLOW THIS WARNING
CAN RESULT IN PERSONAL INJURY AND/OR PROPERTY DAMAGE.

3. During normal operation the pump is immersed in water. Also, during rain storms, water may
be present in the surrounding area of the pump. Caution must be used to prevent bodily injury
when working near the pump:
a. The plug must be removed from the receptacle prior to touching, servicing or repairing the
pump.
b. To minimize possible fatal electrical shock hazard, extreme care should be used when
changing fuses. Do not stand in water while changing fuses or insert your finger into the
fuse socket.
4. Do not run the pump in a dry basin. If the pump is run in a dry basin, the surface temperature
of the pump will rise to a high level. This high level could cause skin burns if the pump is
touched and will cause serious damage to your pump.
5. Do not oil the motor. The pump housing is sealed. A high grade dielectric oil devoid of water
has been put into the motor housing at the factory. Use of other oil could cause serious
electric shock and/or permanent damage to the pump.
6. This pump's motor housing is filled with a dielectric lubricant at the factory for optimum motor
heat transfer and lifetime lubrication of the bearings. Use of any other lubricant could cause
damage and void the warranty. This lubricant is non-toxic; however, if it escapes the motor
housing, it should be removed from the surface quickly by placing newspapers or other
absorbent material on the water surface to soak it up, so aquatic life is undisturbed.
7. In any installation where property damage and/or personal injury might result from an
inoperative or leaking pump due to power outages, discharge line blockage, or any other
reason, a backup system(s) and/or alarm should be used.
Little Giant submersible sewage ejector pumps are recommended for use in basins or lift stations
and suitable for pumping sewage, effluent, wastewater and other non-explosive, non-corrosive
liquids with up to 2" spherical solids.

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).
To conform to the National Electrical Code, all pumps must be wired with 14 AWG or larger wire.
For runs to 250', 14 AWG wire is sufficient. For longer runs consult a qualified electrician or the
factory.
Pump should be connected or wired to its own circuit with no other outlets or equipment in the
circuit line. Use a 20 amp fuse or circuit breaker.
Pump must be installed in a suitable gas-tight basin which is at least 18" in diameter and 24" deep,
and vented in accordance with local plumbing codes.
Pump features a 2" or 3" female NPT discharge.
Pump can be installed with ABS, PVC, polyethylene or galvanized steel pipe. Proper adapters are
required to connect plastic pipe to pump.
Pump must be placed on a hard level surface. Never place pump directly on clay, earth or gravel
surfaces.
A check valve must be used in the discharge line to prevent back flow of liquid into the basin. The
check valve should be a free flow valve that will easily pass solids.
CAUTION: For best performance of check valves, when handling solids install in a horizontal
position or at no more than at a 45° angle. Do not install check valve in a vertical position as solids
may settle in valve and prevent opening on start-up.
When a check valve is used drill a 3/16" hole in the discharge pipe approximately 1" to 2" above the
pump discharge connection and below check valve to prevent air locking of the pump.
This pump is equipped with a remote float switch level control. This level control is sealed in a
polypropylene float cylinder. For automatic operation, the pump must be plugged or wired into a
remote float switch. Pump will run continuously if plugged directly into an electrical outlet.
When the level rises in the basin, the cylinder floats up with the level. When the cylinder position is
at an angle of about 45°, the switch activates and starts the pump motor.
As the level draws down, the cylinder floats down and when it is again at an angle of about 45°, the
switch deactivates, and the pump motor stops.

The motor housing contains oil to provide cooling for the motor and to
lubricate bearings and seals. These pumps are capable of operating with
the motor housing partially exposed for extended periods of time, providing
sufficient motor cooling and bearing lubrication, however, for the best cooing
and longest motor life, the liquid level being pumped should normally be
above the top of the cast iron motor housing.
