DESCRIPTION
Little Giant Submersible Sewage Ejector 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 2” 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.
SPECIFICATIONS
Discharge: 2” or 3” NPT vertical
Intake: 2” diameter opening
Housing: Cast iron
Volute: Cast iron
Impeller: Vortex design with pressure relief vanes
Motor: Single-phase induction 1750 RPM with automatic reset
thermal overload protection

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 cooing
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
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 sewage ejector 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 protector and
may restart unexpectedly. Protector tripping is an indication of motor overloading
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.
6. This pump’s motor housing is filled with a dielectric lubricant at the factory
for optimum motor heat transfer and lifetime lubrication of the bearings.
Use of any other lubricant could cause damage and void the warranty.
This lubricant is non-toxic; however, if it escapes the motor housing, it
should be removed from the surface quickly by placing newspapers or
other absorbent material on the water surface to soak it up, so aquatic life
is undisturbed.
7. In any installation 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, and vented in accordance with local plumbing codes.
Pump features a 2” or 3” 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 no more than at a 45° angle. 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 3/16” hole in the discharge pipe
approximately 1” to 2” above the pump discharge connection and below check
valve to prevent air locking of the pump.
WIRING
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. See Table 2.
REMOTE FLOAT SWITCH LEVEL CONTROL
The RFS series pumps are equipped with a remote float switch level control.
This level control is sealed in a polypropylene float cylinder. For automatic
operation, the pump must be plugged or wired into a remote float switch. Pump
will run continuously if plugged directly into an electrical outlet.
When the level rises in the basin, the cylinder floats up with the level. When the
cylinder position is at an angle of about 45°, the switch activates and starts the
pump motor.
As the level draws down, the cylinder floats down and when it is again at an
angle of about 45°, the switch deactivates, and the pump motor stops.
NOTE: BE CERTAIN PUMP IS SECURE IN BASIN AND CYLINDER FLOATS
UNOBSTRUCTED WITHOUT TOUCHING THE BASIN WALLS OR PLUMBING.
REMOTE FLOAT SWITCH INSTALLATION
1. The float switch consists of three parts: 1) switch, 2) cord clamp, and 3)
clamp screw. NOTE: If screw is lost, use a #10-16 x 1/2” long tapping
screw.
2. Attach cord clamp to pump cover as shown in the switch instruction manual
packaged with the switch. The clamp and pump handle must be positioned
as shown to allow free operation of float. Be sure to locate pump and switch
power cords away from switch float.
3. A 3.5” tether length is recommended. When a tether length of 3.5” is used,
a minimum basin diameter of 18” is recommended. The tether length is
measured as shown in Figure 3.
4. After desired tether length is established, hand-tighten clamp screw.
5. TESTING: Without water in basin plug pump power cord into switch in-line-
plug. Plug switch into outlet. Lift float and watch for pump to operate. Do
not run pump for more than 5 seconds.
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 AND SERVICE
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
