Introduction
This instruction sheet provides you with the information required to safely own and operate your Little Giant pump. Retain
these instructions for future reference.
The Little Giant pump you have purchased is of the highest quality workmanship and material, and has been engineered to
give you long and reliable service. Little Giant pumps are carefully tested, inspected, and packaged to ensure safe delivery
and operation. Please examine your pump carefully to ensure that no damage occurred during shipment. If dam- age has
occurred, please contact the place of purchase. They will assist you in replacement or repair, if required.
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL, OPERATE, OR SERVICE YOUR LITTLE GIANT
PUMP. KNOW THE PUMP’S APPLICATION, LIMITATIONS, AND POTENTIAL HAZARDS. PROTECT YOURSELF AND OTHERS
BY OBSERVING ALL SAFETY INFORMATION. FAILURE TO COMPLY WITH THESE INSTRUCTIONS COULD RESULT IN
PERSONAL INJURY AND/OR PROPERTY DAMAGE!
SAFETY GUIDELINES
1. Ensure that unit is disconnected from power source before attempting to service or remove any component.
2. Do not use to pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in explosive
atmospheres. Pump should only be used with liquids compatible with pump component materials.
3. Do not handle pump with wet hands or when standing on a wet or damp surface or in water.
4. 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.
5. Inanyinstallationwherepropertydamageand/orpersonalinjurymightresultfromaninoperativeorleakingpump due to
power outages, discharge line blockage, or any other reason, use a backup system(s) and/or alarm.
6. Support pump and piping when assembling and when installed. Failure to do so may cause piping to break, pump
to fall, motor bearing failures, etc.
7. If pump is an oil-filled pump, the 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.
ELECTRICAL CONNECTIONS
1. Check the pump label for proper voltage required. Do not connect to voltage other than that shown.
2. If pump is supplied 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 recom-
mended. Do not use an extension cord. Do not cut plug from the cord. If the plug is cut or the cord is shortened,
then this action will void the warranty.
3. If the cord is equipped with stripped lead wires, such as on 230V models, be sure that the lead wires are connected
to a power source correctly. The (green/yellow) wire is the ground. The blue (or white) and the brown (or black)
are live.
SEE INSTRUCTION SHEET ILLUSTRATIONS FOR PROPER ASSEMBLY AND DISASSEMBLY OF YOUR PUMP.
OPERATION
1. The #2E-N model pump must be run submerged. The pump should be placed in an upright position. The volute
must always be in a flooded condition; that is, always under the liquid level.

2. The 2E-38N models can be run in-line or submerged. IMPORTANT: When used in-line, the pump must be installed
so that the pump head (volute) is flooded before starting. That is, the inlet of the pump must be below the level of
the surface of the liquid being pumped. (See Figure 1.) They can be positioned in any attitude, but preferably the
volute should be located to the side.
3. Attempts should be made to support pump using mounting holes in cover, not by intake and discharge connections
alone. The holes are tapped for #8-32 screw. Hole depth is .31". DO NOT exceed the hole depth.
4. Do not attempt to restrict the intake side of these pumps. Restricting the intake may cause damage to the seal and
may starve the pump. If you require reduced flow rates, then place a valve on the dis- charge side of the pump or if
flexible vinyl tubing is used, a clamp can be used on the tubing to restrict the flow.
5. Do not let the unit run dry (without liquid). It is designed to be cooled by pumping fluid. You may damage the seal
and the motor may fail if the pump is allowed to run dry.
6. If the unit is going to be idle for a period of time, follow the cleaning instructions outlined in the next section. Do
not let the unit freeze in the wintertime. This may cause cracking or distortion that may destroy the unit.
7. If fused type plug is used on 230 volt units, a 2.0 amp fuse is recommended.
8. If using an aluminium body pump in an area with water having a high mineral content (hard water) or if other
metals (copper tubing, metal fountain heads, etc.) are present in the pond or fountain, a condition called “galvanic
corrosion” may occur. The recommended solution to this situation is the use of a sacrificial anode attached to the
pump. This anode works on the same principle as the anode found in water heaters and boat motors. Contact your
local distributor and ask for the model SA-1 by Little Giant.

3. First remove the intake screen from the pump. Then remove the three screws as indicated by the arrows. (DO NOT
remove other screws which may be exposed.)
4. Lightly clean any corrosion or debris which may clog the impeller. Use a brush and penetrating oil and lightly scrape
to remove encrusted material.
5. Turn the impeller by hand to make sure it turns freely. Set pump down so the pump and impeller are not touching
anything. Plug the unit into GFCI circuit for 10 seconds to see if the impeller turns; a) If it is rotating and GFCI did not
trip, unplug unit and install parts in reverse order in which they were removed. b) If it does not rotate, if pump is
tripping circuit breakers, or not operating properly after cleaning, return to Little Giant Pump Company or its
authorized service center. DO NOT attempt repairs yourself.
6. Be certain power cord is in good condition and contains no nicks or cuts.

OPERATION
1. The #4E must be run submerged. The #3E may be used submerged or in-line.
a. IMPORTANT: When used in-line, the #3E must be installed so that the pump head (volute) is flooded
before starting. That is, the inlet of the pump must be below the level of the surface of the liquid being
pumped. (See Figure 1.)
2. The pump should be placed in an up-right position
3. The weight of the pump must be supported adequately. DO NOT support the pump by the intake or discharge
connections alone, or by the holes in the top cover. These holes are only intended to connect stabilizing brackets
to pump, which will help prevent pump from tipping. The holes are cored for #8-18 self-tapping screws. Hole
depth is .31". DO NOT exceed the hole depth.

4. Do not attempt to restrict the intake side of these pumps. Restricting the intake may cause damage to the seal
and may starve the pump. If you require reduced flow rates, then place a valve on the discharge side of the pump
or if flexible vinyl tubing is used, a clamp can be used on the tubing to restrict the flow.
