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
CAUTION: To reduce the risk of electrical shock, remove the pump
from power before attempting to service or remove any part.
Read all instructions and safety guide lines thoroughly. Failure to
follow the guidelines and instructions could result in serious bodily
in jury and/or property damage.
Do not pump flammable liquids such as gasoline or fuel oil.
Make sure pump is grounded.
During operation, the area surrounding the pump may be covered
with water; take care when handling the pump.
Do not disconnect plumbing connections when pump is in operation.
Do not stand in water when changing fuses.
PUMP CONSTRUCTION
The patented Little Giant magnetic drive pump design consists of a
cylindrical drive magnet attached to the motor shaft, which rotates
around a chemical-resistant plastic separator housing. Inside this
housing is a magnet fixed to the impeller. The impeller assembly is
free to rotate on a spindle that is supported at both ends. The spindle
is held captive and does not turn. Front and rear thrust washers are
utilized as wear bearings. The washers are held captive and do
not revolve. This prevents wear on the shaft. With the magnetic
coupling the motor drives the impeller. This coupling eliminates the
conventional shaft seal and its possibility of leakage.
PUMP MATERIALS
The pump's plastic parts are made of glass-filled polypropylene.
The spindle shaft and thrust washers are titanium. The impeller-
driven magnet is uncoated Ceramagnet A (barium ferrite) type
ceramic, and the static O-ring seal is Buna-N.
INSTALLATION
This Little Giant pump is completely pre-assembled and pretested
at the factory, and is ready for immediate use. The pump may
be installed in any position. It may be mounted vertically with
the pump head down. Ensure that proper plumbing connections
are made; see specifications table to determine what size intake
and discharge your pump has. Use a thread sealer on all pipe
connections and hand-tighten only. Make sure the wing nuts are
tight before operating the pump. The motor nameplate lists all
electrical data. Make sure the pump is connected to proper voltage
before operating. When wiring pumps with no plug, the green (or
green/yellow) wire is ground, and the other two are line (live).
Do not allow the models to run dry (without liquid). These pumps
are not submersible; operate the pumps only in the in-line mode.
Do not put the units in liquid. Pump should be installed in a dry area
and protected from splash. These pumps are not self priming; they
must be installed so that the pump head (volute) is flooded when
the pump is started. That is, the inlet of the pump must be below the
level of the surface of the liquid being pumped (Figure 1).
Do not restrict the intake side of the pump. Connections on the
intake side should not be of smaller inside diameter pipe or tubing
or hose than the intake inside diameter of the intake thread
designation. If reduced flow is required restrict the discharge side.
Installing a valve or other type of restriction device on the discharge
side is the proper method for reducing flow from the pump. When
using a valve the pump can be throttled to provide various flow rates
and pressures without harming the motor or the pump parts.
