G INTRODUCTION
Little Giant submersible sump 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 SP33 sump pumps have 3/8" spherical
semi-solids handling capability.
Little Giant pumps are carefully packaged, inspected, and tested to ensure safe
operation and delivery. When you receive your pump, examine it carefully to
determine that there are no broken or damaged parts that may have occurred
during shipment. If damage has occurred, make notation and notify the firm
that you purchased the pump from. They will assist you in replacement or
repair, if required.
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 instruc-
tions. Failure to follow this warning can result in fatal electrical shock.
The flexible jacketed cord assembly mounted to the pump must not be modi-
fied 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 overload-
ing 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 trans-
fer 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" FNPT Vertical
Intake Size: 3/8" screened opening
Pump Housing: Thermoplastic
Volute: Thermoplastic
Screen: Thermoplastic
Impeller: Vortex design
Motor: Single phase PSC with automatic reset thermal
overload protection
Hardware:
300 Series stainless steel
Bearings: Ball bearings
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 transfers heat to the volute. 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
cooling and longest motor life, the liquid level being pumped
should normally be above the top of the pump housing.
