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 pumpss 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 damage 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
Ensure the unit is disconnected from the power source before
attempting to service or remove any component.
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.
Do not handle pump with wet hands or when standing on a wet or
damp surface or in water.
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.
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.
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.
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.

WARNING
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 recommended. 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.
CONSULT INSTRUCTION SHEET ILLUSTRATIONS FOR PROPER
ASSEMBLY AND DISASSEMBLY OF YOUR LITTLE GIANT PUMP.
OPERATION
1. The #4E must be run submerged. The #3E may be used
submerged or in-line. 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 upright position as shown in
Figure 2.
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.
5. Do not let the unit operate dry. 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
Figure 1
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 5.0 amp fuse is recommended.
8. If using an aluminum 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 hot water heaters and boat motors. Contact your local
distributor and ask for the model SA-1 by Little Giant.
SERVICE INSTRUCTIONS
MAKE CERTAIN THAT THE UNIT IS DISCONNECTED FROM
THE POWER SOURCE BEFORE ATTEMPTING TO SERVICE OR
REMOVE ANY COMPONENT!
