1. Read these warnings and instructions carefully.
Failure to follow them could cause serious bodily
injury and/or property damage.
2. Follow all local electrical and safety codes as well
as the National Electrical Code (NEC) and the
Occupational Safety and Health Act (OSHA).
3. The power supply should be a separate circuit,
independent of all other circuits. Be sure it is
equipped with a fuse and disconnect box of
ample capacity.
4. For fire protection, the power supply should be
free of any building, preferably on a direct line
from the transformer. In the event of fire, the
wires will not be destroyed and the water supply
not cut-off.
5. Always disconnect power source before
performing any work on or near the motor or its
connected load. If the power disconnect point is
out-of-sight, lock it in the open position and tag
it to prevent unexpected application of power.
Failure to do so could result in fatal electrical
shock.
6. DO NOT handle pump with wet hands or when
standing in water as fatal electrical shock could
occur. Disconnect main power supply before
handling pump for any reason.
7. Shut off power source when voltage drops 10%
below the rated voltage of the motor.
8. Protect the power cable from coming in contact
with sharp objects, oil, grease, hot surfaces or
chemicals. DO NOT kink the power cable. If
damaged replace immediately.
9. NEVER leave the control box, fused disconnect
switch, or covers open (either partially or
completely) when not being worked on by a
competent electrician or repairman.
10. Always use caution when operating electrical
controls in damp areas. If possible, avoid
all contact with electrical equipment during
thunderstorms or extreme damp conditions.
11. Install all electrical equipment in protected area to
prevent mechanical damage which could produce
serious electrical shock and/or equipment failure.
12. Pump is designed to pump cold ground water
that is free of air or gases. Decreased pump
performance and life expectancy can occur if the
ground water is not cold (86F/30C) or contains air
or gases.
13. Pump and controls must be securely and
adequately grounded as specified in section 25043 item (A) of the U.S.A. National Electric Code
(NEC) and Section 26-954 Canadian Electrical
Code. Failure to do so could result in a fatal
injury.
14. DO NOT use this pump to pump flammable
liquids such as gasoline, fuel oil, kerosene, etc.
Failure to follow the above warning could result in
property damage and/or personal injury.
WARNING: The pump is intended for use in a well.
Motor frame must be connected to power supply
ground or fatal electrical shock may result. Do not use
this pump in swimming pools.
WARNING: This product contains chemicals known
to the State of California to cause cancer and birth
defects or other reproductive harm.

READ THESE INSTRUCTIONS COMPLETELY BEFORE INSTALLATION
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.
95 North Oak Street • Kendallville, IN 46755

8. The complete pump and motor should be
IL0077
IL0096
submerged at least ten feet below the draw
down level of the well, and the motor should be
a minimum of ten feet off the bottom of the well
(Figure 4).
9. The Piping — Install the pump with pipe of the
same diameter as the discharge port of the pump
or larger.

Figure 4
Top of Well Screen
Bottom of Well
NOTE: Use of pipe smaller that the discharge port
of the pump will restrict the capacity of the pump and
lower its operating performance.
10. Check Valve — A check valve is required on all
submersible installations. This valve maintains
water within the pipe when the pump is running. A
line check should be installed within 25 feet of the
pump and below the draw down level of the water
supply.
a. For well depths exceeding 200 feet, it is
suggested that an additional check valve be
installed every 125 feet.
b. An additional check valve should be installed in
the horizontal line between the well top and the
pressure tank (See Figures 1 & 2).
CAUTION: Make certain that the check valve is
pointing in the right direction, arrow pointing towards
the tank.
11. Torque Arrester — To center the pump as it is
being lowered into the well, a torque arrester is
recommended. This will also minimize the pump
whipping due to the starting torque of the motor
(See Figure 2).
NOTE: On plastic pipe installations a torque
arrester must be installed. Cable guards should also
be installed.
12. Pressure Tank — The purpose of the pressure
tank is to allow an amount of water to be drawn
before the pressure drops enough to cause the
pump to start. Without a pressure tank, the pump
would start and stop continuously when water is
drawn. There are two types of pressure tanks,
the standard tank that requires an air volume
control and the pre-charged tank.
a. On a standard pneumatic tank system, air
is introduced to compensate for that which
is absorbed by the water. Each time the
pump cycles air is added to the tank through
a bleeder and snifter valve. The excess air
is released by a float assembly (air volume
control) in the upper side tapping of the tank
(See Figure 2).
b. In a pre-charged tank, a flexible diaphragm
or bladder separates the air and water areas
of the tank. The air chamber is pre-charged
by means of a tire valve with pressure 2 PSI
less than the cut-on pressure of the pump.
Because the air is not in contact with the
water, it cannot be absorbed by the water.
Therefore, the original charge of air is never
lost.
13. In pre-charged tank systems, none of the
fittings for air introduction or air level control are
required (Figure 1). The piping in the well is also
different for the two systems. The pre-charged
tank system does not require a bleeder orifice
assembly, which simplifies the installation.

System Filled.
Pump Off
14. The tank size should be selected to keep
the pump starts per day as low as practical
for maximum life. Excessive motor cycling
accelerates motor bearing and spline wear, pump
wear and contact erosion. Use as a guide, 100
starts per day (24 hours) on single phase motors
and 300 starts per day on three phase units.
15. Pressure Switch — The pressure switch provides
for automatic operation. The pump starts when
the pressure drops to the switch cut-in setting
and stops when the pressure reaches the switch
cut-out setting. The pressure switch must be
installed as close to the tank as possible (Figures
1 & 2).
16. Pressure Relief Valve — A properly sized
pressure relief valve must be installed on any
95 North Oak Street • Kendallville, IN 46755
5
installation where the pump pressure can exceed
IL0097
the pressure tank’s maximum working pressure
or on systems where the discharge line can be
shut off or obstructed. The relief valve drain port
should be piped to a drain (Figures 1 & 2).
WARNING: Not providing a relief valve can cause
extreme over pressure, which could result in personal
and/or property damage.
17. Pitless Adapter — A pitless adapter provides
below grade discharge while maintaining above
grade access to the well. Placed below the frost
line they are frost proof and also prevent well
contamination by providing a water tight seal
between the vertical drop pipe and the horizontal
service pipe connection (Figure 1).
18. Well Seal — On well seal installations the
piping in the well projects above the well and is
connected above ground to the system piping by
means of a tee or elbow. Since the plumbing is
above ground, it must be protected from freezing
(Figure 2).
19. Submersible Cable — Submersible power cable
must be UL listed for submersible pump application.
Selecting the proper cable size is important.
Undersized cable results in a too low voltage supply
to the pump motor and ultimate motor failure.
Oversized cable is costly and not necessary. Refer
to cable selection chart for proper cable selection.
Cable is selected for the maximum pump setting
plus the offset distance to the service entrance.
20. Ground Wire — The National Electric Code (NEC
250-43) requires a separate ground wire be run
down the well to the submersible pump and to be
connected to all exposed metal parts of the pump
and motor. Refer to the most recent National
Electric Code (NEC) for additional grounding
information. All wiring should be done by a
competent electrician.
INSTALLATION
SUBMERSIBLE CABLE INSTALLATION
1. 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 hookup work or electrical service work should be done ny a
qualified electrician or serviceman only!
2. Follow wiring directions in the control box and
make momentary tests to see that the motor
runs. Do not run pump dry for more than three (3) seconds. If test is satisfactory, proceed
to Step 3 (cable splice).
3. First check cable size against the Submersible
Wire Size Chart. Use extreme care; this is a very
important step. If required length falls between
two wire sizes, use the larger of the two wire
sizes (smaller number).
IMPORTANT: Use of wire sizes smaller than those
specified in the charts will cause low starting voltage,
may cause early pump failure and will void the
warranty. Larger wire sizes may always be used for
better operating economy.
4. Splice motor leads to submersible cable with
commercially available potting, heat shrink
splicing kits or by careful tape splicing. Tape
splicing should use the following procedure.
a) Strip individual conductor of insulation only as
far as necessary to provide room for a stake
type connector. Tubular connectors of the
staked type are preferred. If connector O.D. is
not as large as cable insulation, build-up with
rubber electrical tape.
b) Tape individual joints with rubber electrical
tape, using two layers; the first extending two
inches beyond each end of the conductor
insulation end, the second layer two inches
beyond the ends of the first layer. Wrap
tightly, eliminating air spaces as much as
possible.
c) Tape over the rubber electrical tape with #33
Scotch electrical tape, (Minnesota Mining Co.)
or equivalent, using two layers as in step “B”
and making each layer overlap the end of the
preceding layer at least two inches.
5. In the case of a cable with three conductors
encased in a single outer sheath, tape individual
conductors as described, staggering joints.
Total thickness of tape should be less than the
thickness of the conductor insulation.

WARNING: Motor frame must be connected to power
supply ground or fatal electrical shock may result.

1. Grounding the submersible pump is
accomplished by running a copper grounding
wire from the pump motor to the main electrical
system ground.
95 North Oak Street • Kendallville, IN 46755

2. The ground wire to be used must be of the same
IL0098
IL0099
size as the submersible power cable. It may be
insulated or bare. If insulated, it must be green,
with or without yellow stripe(s). The ground wire
may be part of, or separate from, the supply
cable. It may be continuous or spliced above the
pump along with the supply cable.
3. The motor lead wire assembly includes a green
insulated ground lead. Splice the ground wire to
the green insulated lead as shown in Figure 6.
4. The other end of the ground wire will be
connected to the power supply grounding
terminal or to the control panel ground bar if it is
connected to the power supply ground.
NOTE: See section entitled Grounding for detailed
grounding instructions.
INSULATION AND CONTINUITY TEST
1. It is recommended that this test be done when
the splicing is complete and pump is being test
run in a tank of water. This test can be repeated
after installation in well but before the final
electrical hook-up is made to the control box or
pressure switch (see Figures 7 & 8).
2. Zero the ohmmeter by clipping the leads together
and adjusting the zero ohm knob until the needle
indicates zero. Zero the ohmmeter before each
use or every time selector switch is changed.
3. Clip one ohmmeter lead to bare cable end.
4. Clip the other lead to edge of steel tank in which
pump and cable are submerged. If pump is
already in the well, clip lead to discharge pipe
metal well casing or bare ground wire.
5. A reading of less that 1,000,000 ohms indicates
that cable or splice is grounded. Slowly raise
cable from the water at the ohmmeter end.
When trouble spot moves clear of the water,
needle will move toward infinity reading. In
an old installation with the pump in the well,
a reading of 20,000 ohms or less indicates a
breakdown in the insulation; in this case pull the
pump.
PUMP INSTALLATION
Figure 7
Figure 8
1. The following pump installation instructions use
Schedule 80 PVC pipe or galvanized pipe. If
either of these two types are used, a foot clamp
or vise will be required to hold the PVC or
galvanized pipe when connecting the next pipe
length.
2. Install the pump in a well which is sand-free,
straight, and has sufficient flow of water to supply
the pump. Clear well of sand and any other
foreign matter with a test pump before installing
the submersible pump.
NOTE: Using the submersible pump to clean the
well will void the warranty. When drilling a new well
in an area where sand is a problem, a sand screen
must be installed to protect the pump and motor.
3. Chlorinate the well first. Drop 24 to 48 HTH
(chlorine) tablets into the well before lowering
the pump into the well. This will prevent
contamination and the growth of iron bacteria
which could later plug the well and the pump.
The chlorinated water will be pumped out of the
system when testing the pump flow.
4. BE SURE the top edge of the well casing is
perfectly smooth; sharp or jagged edges can cut
or scrape the cable and cause a short.
5. Install a line check valve within 25 feet of the
pump and below the draw down level of the water
supply. The check valve should be the same size
as the discharge outlet of the pump or larger.
NOTE: Use of pipe smaller that the discharge
tapping of the pump will restrict the capacity of the
pump and lower its operating performance.
6. When connecting the first length of pipe and
placing the pump in the well casing, care should
be maintained to center the pump in the well. It
is easier to handle the pump if a short piece of
95 North Oak Street • Kendallville, IN 46755
7
pipe is installed first, rather than a long piece.
Install the check valve at the end of the first
piece of pipe prior to lowering the pump into the
well. Maintain alignment as the pump is placed
and lowered into the well, a torque arrester is
recommended. Position the torque arrestor
to within 6” of the pump discharge and clamp
arrestor to pipe. Wrap the pipe with enough tape
at top and bottom of torque arrestor to keep it
from sliding up the pipe while the pump is being
lowered into the well.
7. If not already done, splice the electrical cable
to the motor leads. The cable and ground wire
should be taped to the discharge pipe. Tape the
cable about 5 feet above the discharge and every
20 feet thereafter. Install cable guards if required
to eliminate rubbing against the well casing. Do
not let the cable drag over the edge of the well
casing. Never allow the weight of the pump to
hang on the cable alone.
8. Lower the pump into the well slowly without
forcing. Use a vise or foot clamp to hold the pipe
while connecting the next length. A boom, tripod
or pump setting rig is recommended. Lower
pump to approximately 10 feet below maximum
draw down of the water if possible and keep
approximately 10 feet from the bottom. DO NOT
set pump on bottom of well. Before each new
length of pipe is added, attach the coupling to the
top of the pipe length. This will provide a stop for
the foot clamp to hold while the next section of
pipe is being installed.
9. On a standard tank with an air volume control
a bleeder orifice is required. Install the bleeder
orifice in the discharge pipe 5 feet or more below
the snifter valve. See Figure 2 and the table
below.

1. All installations should have a well seal. Make
sure the seal is seated and tighten the bolts
evenly.
NOTE: Be sure to assemble the tee to the pipe
above the well seal to prevent dropping the pipe and
pump down the well as you lower it.
IMPORTANT: Well seal and piping must be
protected from freezing.
2. On a pitless adapter installation, the connection to
the system supply line is made below ground. Install
the pitless adapter following the instructions included
with particular brand or design being used in the
installation.
NOTE: Follow ALL applicable state and local
plumbing codes.
PRELIMINARY TEST RUN
1. When pump is at desired depth, install throttle
valve for preliminary test run. Wire single
phase motors through the control box, following
instructions in box regarding color coding of
wires, etc. Wire 3-phase motors through a
magnetic starter. Test cable for continuity with an
ohmmeter.
2. With pump discharge throttled, run pump until
water is clear of sand or any other impurities.
Gradually open discharge.
CAUTION: Be sure you do not stop pump before water
runs clear. This may take several hours. If pump
stops with sand in it, it will lock.
3. If pump lowers water in the well far enough
to lose prime, either lower pump in the well (if
possible) or throttle discharge to capacity of the
well.
4. If well is low capacity, use a low water level
control.
5. On 3-phase units, establish correct motor rotation
by running in both directions. Change rotation by
exchanging any two of the three motor leads. The
rotation that gives the most water flow is always
the correct rotation.
PRESSURE TANK INSTALLATION
1. On a new installation, install the pressure tank
along with the pressure switch, pressure gauge,
pressure relief valve, check valve, gate valves
and unions as shown in Figures 1 & 2.
2. On replacement pump installations be sure that
the tank system is in good operating condition, as
a water logged tank may cause pump failure.
ELECTRICAL HOOK-UP
WARNING: Since most submersible pump problems
are electrical, it is very important that all electrical
work be done properly. Therefore, all electrical hookup work or electrical service work should be done by a
qualified electrician or serviceman only!
WARNING: Always disconnect power source before
working on or near motor, its connected load or
control box and wiring. If the power disconnect is out
of sight, lock it in the open position and tag to prevent
unexpected application of power.

1. For proper sizing of fuses for fuse disconnect
box, see Motor Data Charts. Improperly sized
fuses will result in fuses blown or circuit breakers

GROUNDING
Proper Grounding of Submersible Motors
1. The purpose of grounding any electrical
apparatus is to prevent an electrical shock hazard
if exposed metal becomes connected to an
electrical circuit. This can occur from a defect in
construction of the electrical equipment, physical
damage, or a breakdown in the insulation of the
equipment. Grounding prevents shock hazard by
keeping exposed metal from reaching a voltage
level which could endanger anyone coming in
contact with the electrical equipment. Fault
current is “drained” by the ground conductor, and
if the fault is severe enough, the circuit will be
opened by the fuse or circuit breaker.
2. The U.S. National Electrical Code (NEC) requires
that motor-operated water pumps, including
submersible type regardless of voltage, shall
be grounded. The Canadian Electrical Code
specifically discusses grounding requirements
for submersible pumps. Interpretation of these
and other codes may vary in different states and
localities, but all applicable national, state, and
local codes should always be followed.
3. Any submersible motor which is to be run tested
out of the well should be grounded to prevent
possible shock hazard during the test.
NOTE: Always disconnect all power when making
ohmmeter check and while pulling or installing a
pump.
4. The most logical way to “frame” ground a
submersible motor is normally as follows:
a. Run an extra wire with the motor power
conductors. This wire must be sized to meet
Table 250-95 in the U.S. National Electrical
Code. If code information is unavailable, using
the same size wire as the power conductors is
normally adequate.
b. The ground wire may be insulated or bare.
If insulated, it must be green with or without
yellow stripe(s). The ground wire may be
part of, or separate from the supply cable. It
may be continuous or spliced above the pump
along with the supply cable.
c. Connect the green or bare ground wire to the
green ground wire of the submersible motor
lead assembly. If the lead wire assembly does
not include a separate ground wire, attach a
lug to the ground wire and place the lug over
one of the motor studs above the pump intake
flange so the pump will not be cocked. The
Figure 11 — Three Phase Magnetic Starter
95 North Oak Street • Kendallville, IN 46755
9
ground lug will then be secured with the nut
IL0103
which holds the pump on the motor.
d. Connect the other end of the ground wire to
the power supply grounding terminal or to the
control panel ground bar if it is connected to
the power supply ground.
e. All connections should be tight and corrosion
resistant, including screws, lugs or clamps.
Grounding Control Boxes
1. It is recommended the control box grounding
terminal always be connected to circuits which
include a grounding conductor. In fact, this is a
requirement of the National Electrical Code. If
the circuit has no grounding conductor and no
metal conduit from the box to supply panel, use
a wire at least as large as line conductors and
connect from supply panel to the control box and
to the motor lead ground wire.
WARNING: Failure to ground the box frame can
result in a fatal electrical shock hazard if a circuit fault
occurs.
WARNING: Serious or fatal electrical shock may result
from failure to connect all metal plumbing, and the
motor if outside a drilled well, to the power supply
grounding terminal with wire no smaller than motor
cable wires. Do not use motor in swimming area.
Grounding Lightning Arrestors In Control Boxes
1. When the box has a lightning arrestor, it must be
grounded, metal to metal, all the way to the water
strata for the lightning arrestor to be effective.
Grounding the arrestor to a driven ground rod
provides little or no protection for the motor.
SUBMERSIBLE MOTOR COOLING
1. When the pump is set below any screen
openings or below the bottom of the casing a top
feeding well condition can exist which reduces
the rate of cooling water flow past the motor.
2. If the flow rate is less than specified a flow
indicator sleeve or an alternate method of
increasing water velocity past the motor must be
used for proper cooling.
Minimum Velocity Past the Motor
4” dia. motor – .25 ft./sec. (7.62 cm/sec)
6” dia. motor – .5 ft./sec/ (15.24 cm/sec)
3. A flow inducer sleeve is a tube over the motor,
closed off above the pump intake and extended
to the bottom of the motor or lower. The sleeve
material is corrosion resistant metal or heavy
plastic (See Figure 12).
4. A flow inducer sleeve should always be used
when the pump is in an open body of water.
Make sure that such an installation is grounded.
Minimum GPM required for motor cooling in water
up to 86ºF (30ºC).

SERVING SUBMERSIBLE MOTOR AND
CONTROLS
1. The following is included to assist in motor
installation and servicing. These procedures are
limited to the motor and control system: they do
not include pump requirements.
TIGHTENING LEAD CONNECTOR JAM NUT
1. It is recommended that ssible damage from
removal may prevent resealing. Torque the jam
nut from 15 to 20 lb. ft. on Franklin 4” motor and
60 to 70 lb. ft. on a 6” motor.
CABLE IDENTIFICATION WHEN COLOR CODE IS
LOST
(Single Phase Only)
If the colors on the individual drop cables cannot
be determined and the leads cannot be positively
identified, proceed as follows:
95 North Oak Street • Kendallville, IN 46755
10
1. Disconnect all three drop cables from the control
IL0104
box. For temporary identification, tie a numbered
tag to each cable (1, 2, 3).
2. Using an ohmmeter, check the resistance
between cables as follows:
Unknown ValueKnown Value
Cable 1 to Cable 2
Cable 1 to Cable 3
Cable 2 to Cable 3
Lowest - Black to Yellow
Intermed. - Red to Yellow
Highest - Black to Red
NOTE: The “yellow” cable is that giving lowest and
intermediate readings and the “red” cables gives
highest and intermediate readings.
Example:
• 1 to 2 gives 7 ohms (highest reading)
• 1 to 3 gives 5 ohms (intermediate reading)
• 2 to 3 gives 2 ohms (lowest reading)
• Cable 3 gave both intermediate and lowest
reading
• Cable 3 is the yellow cable
• Cable 1 gave both highest and intermediate
readings
• Cable 1 is the red cable
• Cable 2 is the black cable
The actual ohm values are not important. The
method works regardless of the actual ohm readings;
what matters is which reading is highest, which
intermediate, and which lowest.
THREE PHASE POWER UNBALANCE
1. A full three phase supply is recommended for all
three phase motors, consisting of three individual
transformers or one three phase transformer.
So-called “open” delta or wye connections using
only two transformers can be used, but are more
likely to cause problems from current unbalance.

2. Transformer ratings should be no smaller than
listed in the table for supply power to the motor
alone. Open Wye or Delta systems often
suffer from line unbalance, which can cause
poor motor performance, nuisance overload
tripping, or premature motor failure. For the
best performance current unbalance should not
exceed 5 percent. If the unbalance cannot be
corrected by rolling leads, contact the power
company.

Open Delta
Insulation resistance tests indicate the value of the
motor, cable, and splice insulation system by
measuring resistance in ohms between motor leads
and ground. Low readings indicate a breakdown
somewhere in the insulation system.
1. Set ohmmeter to RX100K or highest scale. (For
best results use a megohmmeter).
2. Short meter leads together and adjust indicator to
zero.
3. Be sure power is turned off!
4. Connect one meter lead to a motor lead and the
other meter lead to ground.
a. If motor is out of water, measure from lead to
motor frame.
b. If motor is installed in water, ground reference
should be metal well casing (if submerged),
95 North Oak Street • Kendallville, IN 46755
11
metal drop pipe, or an extra wire extending
into the ground water.
5. Readings and Conditions, motor installed in well:
a. 2,000,000 ohms or more - insulation
completely acceptable.
b. 500,000 to 2,000,000 ohms - insulation
in reasonably good condition. Acceptable.
Should be considered marginal for new motor.
c. 20,000 to 500,000 ohms - insulation seriously
damaged, but motor may still operate.
d. Less than 20,000 ohms - severe insulation
damage. Motor probably not operable.
WINDING RESISTANCE
Winding resistance tests indicate whether or
not windings are internally correct, shorted, or
open. Winding resistance should be considered
independently of insulation resistance readings.
1. Set ohmmeter to RX1. Short meter leads
together and adjust indicator to zero.
2. Be sure power is turned off.
3. Connect ohmmeter between two motor leads.
a. Three wire single phase: Yellow-Black
indicates main winding resistance; Yellow-Red
indicates start winding resistance.
b. Three phase: Resistance values should be
equal on all three phases: Yellow-Black;
Yellow-Red; Black-Red.
4. Correct readings should be equal to the Line-toLine resistance values from the specifications
section for a given motor, plus the resistance of the
drop cable from the table below.
5. Conditions:
Resistance (Ohms) Per 100 Feet of Copper Cable
(Round Trip)
AWG14121086420
Ohms.5.3.2.12.08.05.03.02
a. If one ohm value is less than specified, that
winding is shorted.
b. If one ohm value is greater than specified, that
winding is open, or there is a poor connection
in that circuit.
c. On 3-wire single phase, if one ohm value is
greater than specified and one ohm value is
less than specified, the leads are mixed. See
the section entitled “Cable Identification When
Color Code Is Lost.”
TESTING LOAD CURRENT AMPS
To test load current amps a clamp-on ammeter is
required. Since the ammeter measures current flow,
the motor must be running.
1. Pull the motor lead wire, being measured, (red,
yellow or black) away from all other wires.
2. Set ammeter to the highest scale. (If starting
a motor leave on the scale until current settles
down).
3. Place tongs of meter around wire.
4. Change meter scale to one that gives the best
accuracy. This will be a reading between mid
scale and full scale.
5. Compare reading with current load amps on
motors data chart.
6. Test each motor lead.

CAUTION: WARRANTY ON THREE PHASE SUBMERSIBLE MOTORS IS VOID UNLESS PROPER
QUICK TRIP PROTECTORS ARE USED ON ALL 3 LEAD WIRES.
The characteristics of submersible motors are different from standard motors and special overload protection is required. If the motor is
stalled, the overload protector must trip within approximately 10 seconds to protect the motor windings. In the three phase submersible
motors, the installer must provide the SPECIAL EXTRA QUICK TRIP PORTECTORS AS TABULATED. The heaters given are for ambient
compensated starter boxes; if they are not used, nuisance tripping (over protection) may be experienced at high temperatures and no
protection will exist at low temperatures.
Overload protectors (heaters) for motors of “200-230 volt” ratings should be selected for each installation based on the line voltage
measured at the control panel.
