INTRODUCTION
Little Giant Submersible Effluent 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 3/4" spherical
solids.
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.
Little Giant pumps are carefully packaged, inspected and tested to insure 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
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.
Your115V 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 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 excessively high or low voltage, inadequate wiring, incorrect motor connections, or a
defective motor or pump.
OPERATION
TESTING PUMP OPERATION
RFS SERIES SEWAGE EJECTOR PUMPS:
1. These pumps are equipped with a remote float switch.
2. These pumps are installed in a basin with a sealed cover, so switch operation cannot be
observed. The sump cover usually will have a spare hole that is plugged with a rubber
plug. This plug can be removed and switch operation can be observed.
3. Plug power cord and remote float switch power cord into a grounded receptacle
with voltage consistent with pump voltage as indicated on pump nameplate.
4. Run water into basin until pump starts.
5. Be sure gate valve in discharge line is open.
6. Allow pump to operate through several on-off cycles.
MANUAL SEWAGE EJECTOR PUMPS:
The pump cord for these pumps can be plugged directly into a properly grounded receptacle
with voltage consistent with pump nameplate for continuous pump operation.
CAUTION: This type of operation should be used only for emergency use or when a large
volume of water is to be pumped. Pump must not be allowed to run dry. If pump is run
dry, it may damage pump and void the warranty.
MAINTENANCE
If pump does not operate properly, consult the troubleshooting chart. If trouble cannot
be located with these steps shown, consult your pump dealer or take pump to a Little
Giant authorized service center.
CAUTION: When working on pump or switch, always unplug pump power cord in
addition to removing fuse or shutting off circuit breaker before working on pump.
CLEANING IMPELLER AND VOLUTE
1. Remove screws that hold volute to motor housing.
2. Remove volute and clean impeller and volute passage. Do not use strong solvents
on impeller.
3. Be sure impeller turns freely after cleaning.
4. WARNING: DO NOT REMOVE IMPELLER. REMOVAL OF IMPELLER REQUIRES
SPECIAL TOOLS AND IS TO BE DONE ONLY BY AN AUTHORIZED SERVICE CENTER.
DO NOT REMOVE MOTOR HOUSING COVER. WARRANTY IS VOID IF MOTOR
HOUSING COVER, IMPELLER OR SEALS HAVE BEEN REMOVED.
ANY REPAIR ON MOTOR MUST BE DONE BY AN AUTHORIZED LITTLE GIANT
SERVICE CENTER.
SPECIFICATIONS
Discharge Size:
1-1/2" NPT Vertical
Intake Size:
3/4" Screened Opening
Pump Housing:
Cast Iron
Volute:
Cast Iron
Screen:
ABS
Impeller:
Vortex design, with pressure relief vanes
Motor:
Single phase induction, 1750 RPM, with automatic reset
thermal overload protection.
Hardware:
300 Series Stainless Steel
Thrust Bearing:
Double shielded ball
Radial Bearing:
Sleeve - permanent lubrication
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 a cooling 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 cooling and longest
motor life, the liquid level being pumped should normally
be above the top of the cast iron motor housing.
SAFETY GUIDELINES
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.
INSTALLATION
Pump must be installed in a suitable gas tight basin which is at least 18" in diameter and
24" deep.
Pumps features 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.
