­­­ INTRODUCTION
Little Giant Submersible Effluent Pumps are designed for use in normal sump
and general dewatering applications where higher pressure is required. The
pump is designed for pumping non-explosive, non-corrosive liquids with up to
3/4" spherical solids. Do not use for raw sewage.
Automatic operation can be achieved with the use of the RFS Remote Float
Switch. Other accessories such as basins, check valves and covers are also
available.
All models have a 1-1/2" NPT discharge. Do not over-tighten discharge pipe
into pump volute discharge.
UNPACKING
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
from which you purchased the pump and they will assist you in replacement
or repair, if required.

Discharge: 1-1/2" NPT vertical
Handling Capabilities: 3/4" screened opening
Housing: Cast iron
Volute: ABS plastic
Impeller: Closed design with stainless steel wear ring
Motor: Single phase induction 1750 RPM, with automatic
reset thermal overload protection
Hardware: 300 Series stainless steel
Bearing: Ball
Radial Bearing: Sleeve — Permanent lubrication
Shaft Seal: Mechanical, spring loaded, stationary carbon with
rotating ceramic seat
Impeller Seal: U-cup, Nitrile
Volute Seal: O-ring, formed Nitrile
Motor Housing/
Upper Volute Seal: Vellumoid gasket
Power Cord: 16 AWG 3-conductor copper stranded
Cooling: The motor housing contains a cooling oil to provide
cooling for the motor and to lubricate bearings and
seals. These pumps are capable or 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 cast iron
motor housing.

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 effluent 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 projector and
may restart unexpectedly. Projector tipping is an indication of motor overload-
ing 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.
