GENERAL SAFETY
Risk of explosion. The pump body may explode if
used to boost pressure above the pressures noted on Page 3.
Do not use this pump with inlet pressure greater than 70 psi
(483 kPa)or less than 3 psi (20.7 kPa). If not already in the piping
system, install a pressure relief valve in the pump discharge
line capable of passing the full pump flow at maximum rated
pressure. If local code requires installation of a pressure relief
valve capable of handling the full pump flow at a pressure less
than 100 psi (689 kPa), follow the code requirements.
Risk of fire or explosion. To avoid risk of fire and
explosion, pump water only with this pump. Do not pump salt
water, flammable liquids or chemicals. Do not use the pump near
gas pilot lights or where chemical or gas fumes are present.
Use of an electric pump with liquids other than water or in an
atmosphere containing chemical or gas fumes may ignite those
liquids or gases and cause injury or death due to an explosion
and/or fire. Pump approved liquids only with this pump.
Risk of burns. If water is trapped in the pump during
operation it may turn to steam. Trapped steam may cause an
explosion resulting in injur y or property damage. Never run the
pump with the outlet closed or obstructed.
NOTICE indicates special instructions which are important but
not related to hazards.
The hazards stated in this manual are not all-inclusive. To
minimize the risk of hazard, it is strongly recommended that
installation, operation and maintenance be performed by a
qualified professional in accordance with local codes and
standards for safe operation.

INSTALLATION
GENERAL CONSIDERATIONS
Before installing your submersible turbine pump, review the
following checklist.
Be sure the well is clear of sand and abrasive material
before installing pump. Abrasive materials in the water
cause component wear and reduce pump capacity and
discharge pressure. Never use the pump to develop or clean
the well. Permanent pump damage can result within the
first few hours of operation.
If the well casing is suspected of being crooked, check it
with a gauge of identical length and diameter as the pump
and motor with two lengths of pipe attached. Serious
dam age can result if the pump becomes lodged in a
crooked casing.
Be sure the well can supply a high-capacity turbine pump.
The well should be deep enough to cover the pump unit with
water, even at extreme pumping rates. Typically, the pump
should be submerged 10 to 20 feet below the lowest water
level and at least 5 feet above the bottom of the well.
Air entrained in the water reduces performance and will
dam age the pump.
Your pump is designed to provide maximum efficiency
under specific capacity and head conditions. Do not
oper ate it beyond specified limits.
System controls and pump must match. Do not inter change
controls with other models. Serious damage can result to
the unit if pump and controls do not match.
Average number of starts per day will influence motor
and control component life (starters, relays, capacitors,
etc). Select pump size, tank size and control components
for low est practical number of starts per day. Excessive
cycling accelerates bearing, spline, and pump wear and
con trol contact erosion.

PREINSTALLATION PROCEDURES AND CHECKS
ELECTRICAL SPLICES AND CONNECTIONS
Splices must be waterproof. Make a strong mechanical bond
between the motor leads and the cable to avoid high resistance
at the connection. A poor mechanical con nection, or a poorly
wrapped splice, can cause motor problems and motor failure.
Before connecting the motor to the cable, perform a ground
check to assure that the motor has not been damaged. Attach
one end of an ohmmeter lead to any of the three motor leads
and the other ohmmeter lead to the pump intake bracket. A new
motor must have a resistance of 2 megohms or greater. If not,
contact your dealer. Repeat for all three leads.

Prepare the cable and make the mechanical connections
(Figure 1A) and splices as follows:
1. Cut motor leads and corresponding cable ends at 3-inch spacings to stagger connections for a smooth splice.
2. Cut connecting cable to match the motor leads.
NOTICE: Match color coded wires, red to red, black to black, and white to white.
3. When using a butt connector, expose bare wire for about
1/2”. When using stranded wire, expose about 1” of wire.
NOTICE: Butt connectors may be used with solid wires through 8 AWG, or stranded wires through 10 AWG.
4. Clean exposed ends of wire thoroughly with emery cloth
or sandpaper to assure good electrical connections.
5A. BUTT CONNECTORS (Figure 1A): Insert wires into con nector
until insulation butts up against connector. Crimp connector
to wires with a pair of crimping pliers. Pull on cable to make
sure the connection is solid and tight.
5B. SOLDERED CONNECTIONS (Figure 1A):
NOTICE: Do not use acid core solder or corrosive solder paste.
6. Repeat Step 5 for each lead.

7. Taping splice (Figure 1B):
CAUTION
never use friction tape on a water-tight splice. Use Scotch
Number 33, or equivalent.
7A. Clean joints and adjoining cable/wire insulation of all grease and dirt, and build up joint area with tape until it matches diameter of cable.
7B. Starting 1-1/2” back from the joint, firmly apply one layer of tape, overlapping about half the previous lap and continuing approximately 1-1/2” beyond joint. Cut tape evenly and press both ends firmly against cable.
Because friction tape is not water resistant,
I. Straighten individual cable strands and spread apart
slightly.
II. Clean each strand and push strands of cable into matching
(color-coded) open strands of the motor leads.
III. Wrap entire length of joint with fine copper wire until strands are compressed.
IV. Apply heat and solder. Solder will follow the heat; make sure
solder flows throughout the joint. Pull firmly on cable to test joint.

INSTALLATION
Figure 1C: Sp lice and Cable Continuity
SPLICE AND CABLE CONTINUITY TEST
Before installing pump check cable and splices as follows
(see Figure 1C):
1. Submerge cable and splice in steel barrel filled with water.
Make sure both ends of cable are out of water.
2. Clip one ohmmeter lead to barrel. Test each lead in cable
successively by connecting the other ohmmeter lead to the
three cable leads, one after the other.
3. If resistance reading goes to zero on any cable lead, a
leak to ground is present. Pull splice out of water. If meter
reading changes to “infinity ” (no reading) the leak is in the
splice.
4. If leak is not in splice, slowly pull cable out of water until
reading changes to “infinity”. Reading will change to
“infinity” when leak comes out of water.
5. Repair cable by splicing as explained under “Electrical
Splices and Connections”.
ROTATION CHECK (3-PHASE ONLY)
After satisfactorily completing continuity test, connect cable
to pump controller. Check 3-phase motors for correct rotation.
If necessary, reverse any two cable leads at the controller
and recheck rotation. Permanently mark and match to control
box terminals for future reference. Connect cable to motor
controller and then wire controller to disconnect switch.
Connect temporary jumper wire between proper terminals in
controller to temporarily energize magnetic coil.
Momentarily engage disconnect switch and note direction of
rotation. The shaft should rotate counterclockwise when viewed
from the top or shaft end of the motor. If rotation is incorrect,
reverse any two wires; mark wires to correspond with the
controller terminal numbers.
NOTICE: Pump is water lubricated. Do not operate the pump for
more than 5 seconds while it is out of water.
GENERAL INSTALLATION
After completing all connections and tests so far, connect a
5-foot length of pipe to pump.
Lower pump into well with pipe clamps attached to the 5-foot
pipe. Attach a standard length of pipe to 5-foot length and lower
pump CAREFULLY into well.
NOTICE: Do not use a pipe longer than 5 feet for the first
con nection. Hoisting pump upright with a long length of pipe can
cause pump misalignment from excessive leverage.
CAUTION
to avoid damage to cable insulation.
Anchor power cable to pipe ever y 20 feet with adjustable steel
band clamps. Protect insulation from clamps with pieces of split
rubber hose inserted between clamps and cable. Attach cable to
pipe halfway between clamps with waterproof tape (Scotch No.
33 or equivalent).
Use extreme care when lowering pump and cable
SUBMERGENCE
Be sure the pump is always submerged, even at extreme
pumping rates. Install pump at least 10 to 20 feet below the
lowest “drawdown” water level and at least 5 feet above bottom
of well.
CHECK VALVES
Pump back spin and hydraulic shock can cause severe damage
to the pump and motor. Install at least one check valve in the
discharge pipe (riser pipe) to help prevent this.
Install the first check valve in the pump discharge or in the
discharge pipe it self, not more than 25’ above the pump. Install
another check valve not more than 200 feet above the first one.
Repeat, all the way up the riser pipe. The last check valve on the

NOTICE: To avoid water hammer and pipe breakage, do notput a
check valve exactly half-way up the riser pipe (that is, with equal
distance down to the pump and up to the surface), especially if it
is the only check valve in the riser pipe after the pump discharge
check. The ‘equal distance’ in both legs of the pipe can allow
resonations from water hammer which can blow the pump off the
riser pipe.

Figure 4: Load Current Test
NOTICE: If sand is present in discharge, allow pump to run with
discharge completely open until water is clear. If loud rattling
noises develop, pump is probably cavitating. Gradually close
discharge valve until rattling stops.
INSTALLATION - ELECTRICAL TESTS
Risk of high voltage electrical shock when
testing. Can stun, burn, or kill.
Only qualified electricians should perform these tests. When
testing, use all normal precautions for the voltages involved.
ELECTRICAL TEST OF MOTOR, CABLE, CONNECTIONS
The cable and splices can be damaged as the pump is lowered into
the well. To electrically test them, attach one lead of ohmmeter
to pipe. Attach other lead to each cable lead in tur n. See motor
owner ’s manual for required resistance in a good motor. A low
reading indic ates that cable or splic e has developed a leak to
ground. Remove pump from well and correct problem before
proceeding with installation.
WELL AND PUMP TEST
Check and record static water level of well before starting tests.
Before making final piping connections, test flow rate, capacity,
and condition of well.
NOTICE: Do not operate pump with discharge valve closed.
Operate pump only within pressure and flow limits of operating
range established by performance curve.

Figure 3: Volta ge Test
Measure electrical resistance between motor leads and well
casing when motor is cold.
VOLTAGE TEST (FIGURE 3)
Low or high voltages can cause motor failure. While pump is
operating, check voltage across each pair of leads at motor
controller. Readings more than 10% above or below rated
nameplate voltage can damage pump; correct before placing
pump in service. Test as follows:
1. Disconnect main power supply and open controller.
2. Connect power and start pump. For 3-phase motors, read
voltage across three pairs of leads (L1 – L3, L3 – L2, L2 – L1)
while pump is operating. For single phase motors, read
voltage across L1 and L 2 while pump is operating. Voltage
should be within ±10% of motor nameplate rated voltage. If
not, consult power company.
LOAD CURRENT TEST (FIGURE 4)
Load current should be obtained on each motor lead at the
controller. Partially close pump dis charge valve (keep pressure
and flow within specified operating range) until maximum
amp reading has been obtained. Compare reading with motor
nameplate rating. If reading is 15% or more over rated load,
check for incorrect voltage in supply line or overload due to
abrasives in pump. Find and correct problem before putting
pump in service.
CURRENT UNBALANCE EXAMPLE AND WORKSHEET
3-Ph ase Current Unba lance - Exa mple
Here is an example of current readings at maximum pump loads
on each leg of a three wire hookup. Make cal cu lations for all three
possible hookups.
A. For each hookup, add the readings for the three legs:
Ex.: Hookup #1 Hookup #2 Hookup #3
L1 = 51Amps L1 = 50 Amps L1 = 50 Amps
L2 = 46 Amps L2 = 48 Amps L2 = 49 Amps
L3 = 53 Amps L3 = 52 Amps L3 = 51 Amps
Total 150 AmpsTotal 150 AmpsTotal 150 Amps
B. Divide each total by three to get average amps:
Example: 150/3 = 50
(Calculate the greatest current difference from the average).
Ex. #1 Ex. #2 Ex. #3
50 Amps 50 Amps 50 Amps
–46 Amps –48 Amps –49 Amps

D. Divide this dif ference by the average and multiply by 100 to obtain
the percentage of unbalance. Example:
Ex. 1: 4/50 = .08 x 100 = 8%
Ex. 2: 2/50 = .04 x 100 = 4%
Ex. 3: 1/50 = .02 x 100 = 2%
Use smallest percentage unbalance, in this case Ex. 3.

2. Measure electrical resistance
between motor leads and well
casing with motor
cold.
3. Check pump flow capacity (gallons
per minute).
4. Check pump discharge pressure
(PSI) at operating conditions.
5. Check drawdown level (in feet) from
standing water level.
6. Measure voltage across motor
leadsn while pump is operating.
1. Reference number.
2. See motor manual.
3. At least 90% of readings at
installation.
4. At least 90% of readings at
installation.
5. High enough so that pump does not
break suction.
6. Within ±10% of rated voltage.
1. To aid in monitoring pump
performance.
2. See motor manual.
3. Lower readings may indicate pump
needs repair.
4. Lower reading indicates pump
wear, increased friction losses, or
change in standing water level in
well.
5. Cavitation can damage pump;
increased drawdown may indicate
reduced well flow.
6. If voltage is more than 110% or less
than 90% of rated voltage, consult

Fuses blow or overload
circuit breaker trips when
motor starts:
Fuses blow or overload
trips while motor is running:
Motor does not start but does not
blow fuses or trip circuit breaker:
Pump does not shut off:1. Cable leads improperly connected.1. Check wiring diagram on box cover for correct
Motor runs, but delivers
little or no water:
2. Low or high voltage.
3. Cable damaged or shorted.
4. Pump forced into crooked well.
1. Low or high voltage.
2. Water contains abrasives.
3. Motor or cable shorted and/or
grounded.
1. Fuses blown or circuit breaker tripped.
2. Voltage does not reach terminals.
3. Loose wire in control box.
4. Defective magnetic controller coil.
1. Horizontal line check valve installed
backwards.
2. Motor running backwards
(3-Phase only).
3. Pump gaslocked.
4. Water level in well has dropped.
5. Leak in discharge pipe.
6. Coupling between motor shaft
and pump shaft broken.
7. Pump parts worn from abrasives.

9. Pump set below recommended
depth.
10.Discharge pipe friction reduces
output.
1. Disconnect power unless required for testing.
2. Have electrical testing done by a qualified electrician.
3. Most problems occur above ground. Remove pump from
well only as a last resort.
1. a) Check motor winding resistance - see
“Circuit (Winding) Resistance”, Page 6.
b) If motor is not shorted, turn on current
and rap discharge pipe sharply to loosen sand.
c) Pull pump and clean.
2. Check line voltage (see Page 4). If high or low, contact
power company.
3. Check pump cable for ground (see Page 6).
4. Forcing pump into a crooked hole will cause
misalignment of pump and motor. Consult well driller.
1. Check voltage on service lines (see Page 4).
2. If water contains excessive sand, remove pump and
clean sand out of well.
