G INTRODUCTION
Enclosed with your Little Giant pump is an instruction sheet which
provides you with information required to safely own and operate
your Little Giant pump. The instruction sheet primarily covers the
standard models of each pump series. The form is applicable to
other models in the series not listed by catalog number in the
replacement parts list section of the instruction sheet. If the catalog
number of your pump is not listed in the replacement parts list
section, then caution should be exercised when ordering replacement
parts. Always give the catalog number of your pump when ordering
replacement parts.
The Little Giant unit you have purchased is of the highest quality
workmanship and material It has been engineered to give you
long and trouble-free service. The Little Giant pumps are carefully
packaged, inspected and tested to insured 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.
READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING
TO INSTALL, OPERATE OR SERVICE THE LITTLE GIANT
PUMP. KNOW THE PUMP APPLICATION, LIMITATIONS, AND
POTENTIAL HAZARDS. PROTECT YOURSELF AND OTHERS
BY OBSERVING ALL SAFETY INFORMATION. FAILURE
TO COMPLY WITH INSTRUCTIONS COULD RESULT IN
PERSONAL INJURY AND/OR PROPERTY DAMAGE! RETAIN
INSTRUCTIONS FOR FUTURE REFERENCE.
SAFETY GUIDELINES
1. Make certain that the unit is disconnected from the 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 atmo-
spheres. 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. 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.

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 trans-
fer 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 hous-
ing, 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 recommended. Do not use an exten-
sion 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.

ASSEMBLY AND DISASSEMBLY OF YOUR LITTLE GIANT PUMP.
OPERATION
The NK series pumps must be used in submerged type applica-
tions. The pump is to be placed with the screen as the base or
on the two support legs opposite power cord entry. If the surface
is sandy or muddy, provide a smooth surface for the pump when
placed with the intake down.
The NO-Korode (NK) pumps are designed to be used in mild acids,
alkalies and hard water applications. Before you use the pump in
any of these applications, please check the Little Giant CRC chart
(form # 995516) for compatibility of fluids that come in contact
with pump parts. The pump materials consist of: glass-filled nylon
housing, nylon volute, plate, impeller and elbow, stainless steel
motor shaft and fasteners, nitrile square cut seal (between volute
and plate), Viton shaft seal and polyethylene screen. The cord jacket
is PVC material. Other plastic parts are nylon.
Do not restrict the intake side of the pump. Restricting intake may
cause damage to the shaft seal. If less flow is required, restrict the
discharge side of the pump. For example, if plastic tubing is used,
place a clamp on the tubing to restrict the flow by squeezing the
tubing.
Do not let the unit operate dry. It is designed to be cooled by the
pumping fluid. You may damage the seal and the motor may fail
if the pump is allowed to run dry.
If the unit is going to be idle for a period of time, follow the cleaning
instructions that follow before you store the unit. Do not allow the
unit to freeze in wintertime. Freezing may cause cracking or distortion
of the plastic parts which will destroy the pump.
