G 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!
Little Giant submersible sump and effluent pumps are recommended for use
in basins or lift stations, and are suitable for pumping effluent, wastewater, and
other non-explosive, non-corrosive liquids. The SC50 series pumps have 1/2"
spherical solids handling capability. Other accessories such as basins, check
valves, and covers are also available.
SAFETY GUIDELINES
RISK OF ELECTRIC SHOCK: This pump is supplied with a grounding
conductor and grounding-type attachment plug. To reduce the risk of
electric shock, be certain that it is connected only to a properly grounded,
grounding-type receptacle.
Your pump is equipped with a 3-prong electrical plug. The third prong grounds
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 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 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 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 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 sump 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 oil for motor heat
transfer and lifetime lubrication of the bearings. This oil is non-toxic to
aquatic life. However, suffocation can occur if oil is left on the water surface.
If oil escapes the motor housing it can be removed from the surface quickly
by placing newspapers on the water surface to soak up the oil.
7. In any installations 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.
SPECIFICATIONS
Discharge Size: 1-1/2" NPT vertical
Intake Size: 1/2" screened opening
Pump Housing: Cast iron
Volute: Plastic
Screen: Plastic
Impeller: Vortex design
Motor: Single phase shaded pole with automatic reset
thermal overload protection.
Hardware: 300 series stainless steel
Bearings: Sleeve
Pump Shaft Seal: Mechanical, spring loaded, stationary carbon with Nitrile
boot and rotating ceramic seat
Power Cord: 16 AWG 3-conductor, copper, stranded
Cooling: The motor housing contains oil to cool 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, as long as sufficient motor cooling and bearing lubrication
is provided. However, for the best cooling and longest motor
life, the liquid level being pumped should normally be above
the top of the cast iron motor housing.
ELECTRICAL CONNECTIONS
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. Fuses and circuit breaker should be of ample
capacity in the electrical circuit.
INSTALLATION AND OPERATION
Pump must be installed in a suitable gas-tight basin that is at least 18" in
diameter and 24" deep.
The SC50 series pumps feature a 1-1/2" 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 an angle of no more than 45°. 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 relief hole (1/8" or 3/16" diameter) in the
discharge pipe. This hole should be located below the floor line between the
Figure 1.
