DESCRIPTION
Little Giant submersible sump and sewage 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 pumps have 2” spherical solids
handling capability. Accessories such as basins, check valves, and covers
are available through your Little Giant dealer.

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, providing sufficient motor cooling
and bearing lubrication. 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.
SAFETY GUIDELINES
WARNING: RISK OF ELECTRIC SHOCK.
This pump is supplied with a ground-
ing conductor and 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 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 or lift station, 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. Do
not modify the power cord except to shorten it 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 prop-
erty 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. Use cau-
tion to prevent bodily injury when working near the pump:
a. Remove the plug from the receptacle before touching, servicing, or
repairing the pump.
