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
During installation, follow all local electrical and safety codes, as well as the National
Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA).
DUAL VOLTAGE MOTORS: For voltage change instructions, see motor label or
wiring access cover.
Have an electrician provide electrical power to the motor.
See Table 1 for recommended wire gauges.
Ground motor and secure terminal cover in place to reduce electrical shock
hazard.
The pump is not submersible and is intended for open-air use only. Do not
submerge motor or mount pump in a location where motor will come in contact
with water. This pump is not designed for use in showers, hot tubs, spas, pools,
or other potentially wet locations. Installing this pump in such an application
could result in personal injury or death.
Make certain that the unit is disconnected from the power source before
attempting to service or remove any component. If the power disconnect is out
of sight, lock it in the open position and tag it to prevent unexpected application
of power.
VOLTAGE WIRING INSTRUCTIONS
CAUTION: DO NOT move the wires on L1 and L2.

APPLICATION
The shallow well jet pump is ideal for the supply of fresh water to rural homes,
farms and cabins. This pump is suitable for installations where the vertical
distance from the pump to the water level does not exceed 25 ft. (7.6m),
including drawdown (less at high altitudes).
In offset installations, friction losses in the suction pipe must be taken into
consideration. (Refer to Table 3, Friction Loss.)
INSTALLATION
Pump Location: Install the pump in a clean, dry, ventilated location that
provides adequate room for servicing and protection from freezing temperatures.
It should be bolted to a good foundation (preferably concrete) and provided with
adequate drainage. Locating the pump as close as possible to the water source
will reduce the friction in the suction pipe and ensure maximum capacities.
Suction and Pressure Pipe: Use only new, clean 1-1/4" pipe or hose. If the
pump is installed any appreciable distance away from the source of water, the
suction pipe should be increased to 1-1/2". Horizontal lengths of pipe must
gradually slope upwards from the source of water to the pump to avoid air
pockets in the line. Thread compound should be used on all pipe joints and
connections should be thoroughly tightened. Install a foot valve and check
its operation because a leak will prevent proper operation of the system.
Make sure the foot valve is located so that it will be submerged at all times. If a
sandpoint or driven well is used, install a check valve next to the pump suction
instead of the foot valve (Figure 7). All installations must have a foot valve or
a check valve in the suction pipe.
Pump to Tank Fittings: The discharge pipe from the pump to the tank should
be as short and direct as possible and should be the same size as that of the
pump discharge tapping. A check valve should never be installed between the
pump and the tank.
Service Line: Connect the service line as shown in Figures 5 - 8. The size of the
service line required is governed entirely by the amount of water needed and the
length of the pipe. The pipe selected should be large enough so that the friction
loss (determined from Table 3, Friction Loss) will never exceed 20 ft. (6m) head.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding must comply with
the National Electrical Code (NEC) and with any local codes and ordinances.
Employ a licensed electrician.
WARNING - RISK OF ELECTRICAL SHOCK
Wiring: Employ an electrician to do the wiring and connect the electrical
service to the pump.
The pressure switch is wired to the motor at the factory and the voltage for
which the motor is wired is indicated by a sticker where applicable. Make sure
the motor is wired for the same voltage as the power supply. Refer to the motor
nameplate or inside terminal cover for voltage changing instructions. The power
lines should be connected to the pressure switch terminals marked L1 and L2
(Figure 4). It is recommended that a separate circuit be led from the distribution
panel to the pump unit. A ground fault circuit interrupter (GFCI) protected circuit
should be used for all electrical devices operating near water. Install a proper
fused disconnect switch in the line and make certain the wiring is adequately
sized and well insulated. Undersized wire between the motor and the power
source will adversely limit the starting and load carrying abilities of the
motor. Minimum wire sizes for motor branch circuits are recommended in Table
1. For added safety, ground the pump and motor to the well casing (if metal) or
the ground in the distribution panel.
Pressure Gauge: If a pressure gauge is supplied with the pump or if you wish
to install a pressure gauge, it should be installed into the 1/4" NPT hole on the
front of the casing directly beside the discharge opening.
