ASSEMBLY
CAUTION: Be sure pump size corresponds with
horsepower size of motor. If pump size exceeds
recommended motor, overloading of motor and
damage to the motor could result.
1. If not yet assembled, check that the pump and
motor mounting faces are free from dirt.
2. Assemble the pump liquid end and motor
together so that mounting faces are in contact.
Then tighten assembly bolts evenly.
NOTE: Apply non-toxic FDA approved waterproof
grease such as Mobile 102, Texaco CYGNUS2661 or
equivalent to the coupling before assembly of pump
coupling to motor shaft. This will prolong spline life
and prevent abrasives from entering the spline area.
3. Check for free rotation of the pump and motor. A
slight drag is permissible.
4. Assemble the pump lead guard over the motor
leads.
CAUTION: Do not cut or pinch lead wire during
assembly.
5. Assemble suction screen to pump mounting ring.

PRE-INSTALLATION
To save possible added expense and extra trips,
observe and complete as many as possible of the
following precautions and pre-installation procedures
before going to the job site or beginning the
installation.
IMPORTANT PRECAUTIONS
1. Prior to installation, inspect the pump for damage.
Check for free pump and motor rotation. A slight
drag is permissible.
2. Check to make certain that the voltage of the
motor end and control agree with the available
phase and voltage. Check power source. Check
electrical supply for correct fusing, correct wire
size, and adequate grounding and transformer
size.
WARNING: Since most submersible pump problems
are electrical, it is very important that all electrical
work be done properly. Therefore, all electrical hook-
up work or electrical service work should be done by a
qualified electrician or service man only!
3. Throughout installation, take care not to damage
the insulation of the electrical cable or motor
leads. Never support the weight of the unit by
electrical cable or motor leads.
4. Before the pump is installed, the well should be
pumped free of sand and other foreign matter
with a test pump. The warranty is void if it is
used to clean the well.
5. Follow wiring directions in the control box and
make momentary tests to see that motor runs.
(It is normal to hear some noise from the pump
when you are momentarily testing it). Do not run
pump dry for more than three (3) seconds.
MAJOR WELL COMPONENTS (see Figures 1 & 2)
1. Submersible Pump — A submersible pump is a
multi-stage centrifugal. Each stage consists of an
impeller and diffuser. Water pressure increases in
equal amounts as it passes from stage to stage.
The more stages, the higher the pressure the
pump will develop.
2. Submersible Motor — Submersible pumps can
be powered by either single phase or three phase
motors. Make certain that the motor corresponds
with the horsepower required by the pump.
Failure to do so, could result in overloading of the
motor and motor damage.
3. Control Box — Single phase submersible motors
require the use of an above ground control box
for starting. Operation of these motors without
control boxes or with incorrect boxes can result in
failure of motors which will void the warranty.
4. Magnetic Starters and Overload Protection
— Three phase submersible motors require the
use of an above ground magnetic starter and
overload protection. Operation of these motors
without or incorrect starters and protectors will
result in the failure of motor which will void
the warranty. See Magnetic Starter Chart for
the correct selection of magnetic starters and
ambient compensated quick trip protectors.
5. The Well — The well should be sand free and
have a sufficient flow of water to supply the
pump. Clear well of sand and any other foreign
matter with a test pump before installing the new
submersible pump.
CAUTION: Using the submersible pump to clean the
well will void the warranty.
6. When drilling a new well in an area where sand is
a problem, a sand screen should be installed to
protect the pump and motor.
7. The well should be straight so damage during
installation does not occur to the pump or motor
by becoming lodged in a crooked well casing.
