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 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
1. CAUTION: To reduce risk of electric shock, pull plug before
servicing this pump.
2. This pump is designed to pump water. DO NOT PUMP strong
chemicals, solvents, brines, or thick liquids such as oils or
grease.
3. Do not pump flammable liquids such as gasoline or fuel oil.
4. During operation the area around the pump may be covered
with water. Take care when handling the pump. Do not pull
pump out of water when running by the power cord.
5. Do not stand in water when changing fuse.
6. Make sure outlet is grounded.
7. The National Electric Code requires a Ground Fault Circuit
Interrupter (GFCI) be installed in the branch circuit supplying
fountain equipment, ponds, etc. See your local electrical
supply dealer for various brands of GFCI devices.
8. 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.
ELECTRICAL CONNECTIONS
Your 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.
INSTALLATION
1. Clean any debris from the sump pit and set the pump in the
center of the pit. A solid bottom will prevent sand and dirt from
clogging the pump.
2. Connect the discharge piping and run it to the nearest sewer
or surface outlet. Use pipe joint compound at all connections.
Sump pumps can be piped to discharge into the house
drainage system, to a dry well, splash block, or to a a storm
drain, depending on local plumbing codes. The discharge pipe
should be as short as possible and contain as few elbows as
possible. The discharge pipe should be the same diameter as
the discharge size to reduce pipe friction losses. Smaller pipe
will restrict capacity and reduce pump performance. The sump
pump comes with 1” female pipe thread discharge.
3. Always install a union in the discharge line, just above the sump
pit, to allow for easy removal of the pump for cleaning or repair.
4. In situations where the piping is long, the vertical discharge is
above 7 or 8 feet, or a small pit has been provided, use of a
check valve is recommended to prevent backflow of water into
the sump. When a check valve is used, drill a relief hole (1/8”
or 3/16” diameter) in the discharge pipe. This hole should be
located below the floor line between the pump discharge and
the check valve. Unless such a relief hole is provided, the pump
could air lock and will not pump water even though it will run.
5. Tape the switch cord and pump cord to the discharge line with
electrician’s tape. This will protect the cords from damage and
will prevent them from interfering with the float.
6. TEST THE PUMP AFTER ALL CONNECTIONS HAVE BEEN
MADE. Run water into sump. Do not attempt to operate the
pump without water; this will damage the seals and bearings
and could result in permanent damage to the pump. Fill sump
