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 3 for recommended cable sizes.
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.

APPLICATION
The convertible jet pump is ideal for the supply of fresh water to rural homes,
farms and cabins that have suction lifts down to 90 feet. This pump may be
installed as a shallow well unit with the injector mounted to the casing. For a
deep well unit the injector is mounted in the well and either combination of
venturi or nozzle may be used. For vertical lifts of 25 ft. (7.5m)* or less, install as
a shallow well unit (Figure 2).
For vertical lifts beyond 25 ft. (7.5m), install as a medium depth deep well or as a
deep well unit (Figure 3). In offset installations, friction losses in the suction pipe
must be taken into consideration. (Refer to Table 5, Friction Loss.) This pump is
not tested for use in swimming pool areas.
CONVERSION
Refer to the following section to convert your pump to the appropriate
application.
Tools required :
• 3/4" deep socket (for nozzle)
• 5/8" Allen wrench or adjustable pliers (for venturi)
The convertible jet pump is suitable for:
• shallow wells to 25 ft. (when injector is bolted to casing);
• medium-deep wells to 40 ft. (when injector is installed in well);
• deep wells to 90 ft. (when injector is installed in the well).
Note: Use a 6 inch long (minimum), 1-1/4" NPT hose adapter to connect nozzle
to pipe (Figure 4).
