SAFETY WARNINGS
Important notice: Read safety instructions before
proceeding with any wiring.
WARNING All electrical work must be performed by
a qualified technician. Always follow the
National Electrical Code (NEC), or the Canadian Electrical Code, as well as all local, state and provincial codes.
Code questions should be directed to your local electrical
inspector. Failure to follow electrical codes and OSHA safety
standards may result in personal injury or equipment damage. Failure to follow manufacturer’s installation instructions
may result in electrical shock, fire hazard, personal injury or
death, damaged equipment, provide unsatisfactory performance, and may void manufacturer’s warranty.
WARNING Standard units are not designed for use in
swimming pools, open bodies of water,
hazardous liquids, or where flammable gases exist. Well must
be vented per local codes. See specific pump catalog bulletins
or pump nameplate for all agency Listings.
WARNING Disconnect and lockout electrical power
before installing or servicing any electrical equipment. Many pumps are equipped with automatic
thermal overload protection which may allow an overheated
pump to restart unexpectedly.
WARNING Never over pressurize the tank, piping or
system to a pressure higher than the tank's
maximum pressure rating. This will damage the tank, voids
the warranty and may create a serious hazard.
WARNING Protect tanks from excessive moisture and
spray as it will cause the tank to rust and
may create a hazard. See tank warning labels and IOM for
more information.
WARNING Do not lift, carry or hang pump by the
electrical cables. Damage to the electrical cables can cause shock, burns or death.
WARNING Use only stranded copper wire to pump/
motor and ground. The ground wire must
be at least as large as the power supply wires. Wires should
be color coded for ease of maintenance and troubleshooting.

SAFETY WARNINGS
Install wire and ground according to
the National Electrical Code (NEC), or
the Canadian Electrical Code, as well as all local, state and
provincial codes.
WARNING Install an all leg disconnect switch where
required by code.
WARNING The electrical supply voltage and phase
must match all equipment requirements.
Incorrect voltage or phase can cause fire, motor and control
damage, and voids the warranty.
WARNING All splices must be waterproof. If using
splice kits follow manufacturer’s instructions.
WARNING Select the correct type and NEMA grade
junction box for the application and location. The junction box must insure dry, safe wiring connections.
WARNING All motors require a minimum 5' submergence for proper refill check
valve operation.
WARNING Failure to permanently ground the pump,
motor and controls before connecting to
power can cause shock, burns or death.
WARNING All three phase (3Ø) controls for submersible pumps must provide Class 10,
quick-trip, overload protection.
WARNING 4" motors ≥ 2 HP require a minimum
flow rate of .25 ft/sec. or 7.62 cm/sec.
past the motor for proper motor cooling. The following are
the minimum flows in GPM per well diameter required for
cooling: 1.2 GPM/4", 7 GPM/5", 13 GPM/6", 20 GPM/7",
30 GPM/8" or 50 GPM in a 10" well.
WARNING Pumps ≥ 2 HP installed in large tanks
should be installed in a flow inducer
sleeve to create the needed cooling flow or velocity past the
motor.

TYPICAL SYSTEM
Motor Cooling, Temperature
and Time Ratings
All 4 inch CentriPro motors may be
operated continuously in water up to 86º
F. Optimum service life will be attained
by maintaining a minimum flow rate past
the motor of .25 feet per second. Use a
Flow Sleeve if velocity is below the .25'/
sec, if the well is top feeding or when the
pump is used in a large body of water or
large tank.
Six (6) inch canned design motors from
5 – 40 HP will operate in water up to
95º F (35º C), without any de-rating of
horsepower, with a minimum flow rate of
.5 ft./sec. past the motor. 6" – 50 HP and
all 8" – 10" motors can operate in 77º F
(25º C) water with .5'/sec velocity past
FLOW SLEEVE
the motor.
One way to make a flow sleeve is to install a well seal
above the pump discharge and slip a piece of casing
over the pump and affix it to the well seal. Drill three
holes at 120º intervals on the lower section of the casing
and insert (3) screws and nuts through the casing, just
touching the motor. Tighten the nuts out against the
casing. Insure that the screws do not protrude out too
far as you don’t want them catching on well joints.
Pump Cooling and Lubrication
In addition to motor cooling, another reason to
maintain minimum flow rates is pump lubrication. All
manufacturers’, either on curves or in selection charts,
show minimum flows. This insures that rotating pump
parts are properly lubricated to prolong service life and
reduce friction. A dead headed pump will super heat
water very quickly, and hot water has no lubricity.

AMPROBE/OHMMETER INSTRUCTIONS
The Amprobe is a multi-range, combination
ammeter and voltmeter.
Voltmeter Scales: 150 Volts
600 Volts
Ammeter Scales:
5 Amps
40 Amps
15 Amps
100 Amps
1.When used as an ammeter, the tongs are placed around the wire being measured with the rotary scale on the 100 amp range. Then rotate the scale back to the smaller ranges until an exact reading is indicated.
2. When used as a voltmeter, the two leads are clipped into the bottom of the instrument with the rotary scale on the 600 volt range. If the reading is less than 150 volts, rotate the scale to the 150 volt range to get a more exact reading.
10
CAUTION
Use Ohmmeter only with power off.
11
AMPROBE/OHMMETER INSTRUCTIONS
The Ohmmeter is used for measuring the
electrical resistance of a wire circuit. The unit of
measurement is called an Ohm.
1.The knob at the bottom of the Ohmmeter is adjustable through six ranges:
RX1
= R x 1
If your ohmmeter
RX10
= R x 10
is digital readout
RX100
= R x 100
type, refer to the
RX1000 = R x 1,000
instructions that
RX10K = R x 10,000
came with it.
RX100K = R x 100,000
2. The round center knob is for the purpose of adjusting the instrument to zero (0) after clipping the two ohmmeter leads together. This must be done every time the range selection is changed.
MEASURING INSULATION RESISTANCE
Megger
This instrument is used to measure insulation
resistance to ground. It consists of a crankturned magneto, on the side of the case, and
will give very close readings calibrated directly in ohms. It is cranked at a moderate rate
of speed, approximately 120 rpm, until the
pointer reaches a steady deflection.
1. If the ohm value is normal, the motor
windings are not grounded and the cable
insulation is not damaged.
2. If the ohm value is below normal, either the
windings are grounded or the cable insulation is damaged. Check the cable at the well
seal as the insulation is sometimes damaged
by being pinched.

CABLE CHECKOUT
Checking Cable and Splice
1. Submerge cable and splice in steel barrel
of water with both ends out of water.
2. Set ohmmeter selector on RX100K and
adjust needle to zero (0) by clipping
ohmmeter leads together.
3. After adjusting ohmmeter, clip one
ohmmeter lead to barrel and the other to
each cable lead individually, as shown.
4. If the needle deflects to zero (0) on any
of the cable leads, pull the splice up out
of the water. If the needle falls back to (∞)
(no reading) the leak is in the splice.
5. If leak is not in the splice, pull the cable
out of the water slowly until needle falls
back to (∞) (no reading). When the needle
falls back, the leak is at that point.
6. If the cable or splice is bad, it should be
repaired or replaced.

What it Means
1. If all ohm values are normal, the motor windings are
neither shorted nor open, and the cable colors are
correct.
2. If any one ohm value is less than normal, the motor is
shorted.
3. If any one ohm value is greater than normal, the winding
or the cable is open or there is a poor cable joint or
connection.
4. If some ohm values are greater than normal and some
less, the leads are mixed.

Properties.
NOTE: Motors and control boxes are designed to
operate on 230V systems. Systems with low line
voltage, between 200 – 207 volts require the next
larger cable size than shown in the 230V charts.
If using a 3-wire motor with control box on a low
voltage application switch to a 208V start relay.

To size wire, the voltage drop of each wire segment must be used and the total
must not exceed 100%.
Example: a 1.5 HP motor, 100' from Service Entrance to Controller (1Ø wire)
and 500' from Controller to Motor (3Ø wire).
• Service Entrance to Controller = 100' of # 10 (100/455) = 22 % (455' from
230V 1Ø chart)
• Controller to Motor = 500' of # 12 (500/709) = 71 % (709' from the 3Ø chart)
• 71% + 22% = 93 %; See Balanced Flow Bulletin or IM182 for more info.

PRESSURE TANK CHECKOUT PROCEDURE
1.To check: Shut off power supply and drain system to “0” pressure.
2.Air pre-charge in tank should be 2 psi less than the cut-in pressure of the pressure switch.
Example: If pressure switch setting is 30-50 psi, tank should be pre-charged with 28 lbs. air.
3.If water at valve, replace tank.
RULE OF THUMB
Improper tank sizing may cause motor damage.
½ to 1½ HP pumps – Tank draw down
should be equal to the pump capacity in
GPM or greater.
Example: ¾ HP pump; capacity 12 GPM;
pressure switch setting 30/50 PSI; correct
tank – V140.
2 HP and larger pumps – tank drawdown should be double the pump capacity in GPM.
Example: 3 HP pump; capacity 30 GPM;
pressure switch setting 40/60 PSI; correct
tank selection: 2 – V350 tanks.

JET PUMPS
Jet Pump Reassembly . . .
1. Be sure that recess for seal seat and surface
where guide vane mounts on motor adapter
are entirely free of all scale and dirt.
2. Clean motor shaft.
3. Apply film of light oil, such as vegetable oil,
to the recess of the motor adapter and the
neoprene bushing before installing the new
seal seat. This is a tight fit, but it must go in
all the way evenly, or a leak will result. Do not
mar lapped face of this seal. The slightest scar
or particle of dirt will cause a leak.
4. Bolt motor adapter to motor, making sure the
motor shaft does not dislocate the stationary
seal member.
5. Assemble rotating member of seal on motor
shaft. Rotating seal face must fit snugly
against lapped seal face of stationary
member in casing cover. This is accomplished
by pushing with a piece of tube against back
end of neoprene washer after oiling sleeve
and shaft. Be sure rotating seal face does not
drop out of holding collar while sliding the
rotating members of the seal on the shaft.
Also, take extra care that the rotating seal face
is not marred during handling.
6. While holding the shaft against rotating, screw
impeller on shaft by hand until tight against
shoulder of motor shaft.
7. Replace guide vane, making sure that bore
of guide vane does not bind impeller hub. If
screws used, tighten alternately and evenly.
Check by turning the motor shaft. If binding
occurs, loosen screws, readjust guide vane
until impeller hub turns freely, then tighten
screws as before. Some jets have snap-in
guide vane.
62

RULE OF THUMB
Practical suction lift at sea
level is 25 ft. Deduct 1 ft. of
suction lift for each 1,000 ft. of
elevation above sea level.
Shallow Well System
Install vacuum gauge in shallow well adapter.
See opposite page. When pump is running,
the gauge will show no vacuum if the end of
suction pipe is not submerged or there is a
suction leak. If the gauge shows a very high
vacuum (22 inches or more), this indicates that
the end of suction pipe is buried in mud, the
foot valve or check valve is stuck closed or the
suction lift exceeds capability of pump.
High Vacuum (22 inches or more)
• Suction pipe end buried in mud
• Foot valve or check valve stuck closed
• Suction lift exceeds capability of the pump
Low Vacuum (or 0 vacuum)
• Suction pipe not submerged
• Suction leak
81
CHECKING SUCTION LIFT
A vacuum gauge indicates total suction lift
(vertical lift + friction loss = total lift) in inches
of mercury. 1" on the gauge = 1.13 ft. of total
suction lift (based on pump located at sea
level).
CHECKING SUCTION LIFT
Compound Vacuum
Pressure Gauge
This gauge will show
the pressure or vacuum
at any position in a
pump or system where
it is installed.
A reading of 20" on a vacuum gauge placed
on the suction side of the pump would tell
you that you have a vacuum or suction lift of 22.6 ft.
20" x 1.13' = 22.6 ft.

RULE OF THUMB
If pressure control valve is set too high,
the air volume control will not function.
If pressure control valve is set too low,
the pump may not shut off.
To Adjust Pressure Control Valve:
1. Close pressure control valve.
2. Open faucet in house.
3. Turn pump on.
4. As pump picks up its prime, the pressure will
begin to rise on the gauge.
5. Turn adjusting screw to set pressure control
valve to pressure recommended in catalog.
83
PRESSURE CONTROL VALVES
When pump is first started or under maximum
flow condition, pressure control should
be immediately adjusted to the pressure
corresponding to H.P. and jet assembly used.
See rating tables in catalog for proper pressure
setting.
1.Turn left to reduce pressure.
2.Turn right to increase pressure.
ROTATION
Correct rotation is a must on all 3Ø
installations. Rotation can be checked by
one of these three ways:
Visual 1
1.Connect 3 motor leads to starter, run unit at
open discharge.
2.Switch any 2 leads and again run unit at
open discharge.
3.Largest quantity of water indicates correct
rotation.
Visual 2
1.Remove water end from meter. Run motor
and observe rotation
Pressure
1.Connect 3 motor leads to starter. Run unit
against closed discharge, take maximum
pressure reading.
2.Switch any 2 leads and again run unit
against closed discharge. Take maximum
pressure reading.
3.Highest pressure reading indicates correct
rotation.

!
CAUTION
To prevent changing motor rotation, the
motor leads should be reordered in the
same direction, see example on page 51.
RULE OF THUMB
If the unbalance moves with the motor
leads the unbalance is caused by the
motor, wet splice, or damaged cable. If
the unbalance remains with the terminals
the unbalance is in the power supply.
85
THREE PHASE UNBALANCE
L1
THREE PHASE UNBALANCE
Calculate percentage of current unbalance for
all three hookups.
Example:
Hook Up 1
Hook Up 2
Hook Up 3
T1 = 51 Amps
T3 = 50 Amps T2 = 50 Amps
T2 = 46 Amps
T1 = 48 Amps T3 = 49 Amps
T3 = 53 Amps
T2 = 52 Amps T1 = 51 Amps
Add up all three readings for hook up number 1.
T1 = 51 Amps
T2 = 46 Amps
+T3 = 53 Amps
Total 150 Amps
Divide the total by three to obtain the average.
50 Amps = Average
3 150 Amps
Calculate the greatest amp difference from the average. Could be greater than average.
50 Amps
-46 Amps
4 Amps
Divide this difference by the average to obtain the
percentage of unbalance.
.08 or 8%
50 4.00 Amps
Hook Up #1 = 8%
Hook Up #2 = 4%
Hook Up #3 = 2%
Always use hook up with lowest % current unbalance.
Loads on a transformer bank vary. Readings should be
taken at peak load period.
What It Means –
1. Hook ups below 5% = system balanced.
2. Hook ups not below 5% – if the unbalance moves with
the motor leads the unbalance is caused by the motor,
wet splice, or damaged cable. Check the motor on
pages 44-45. If the unbalance remains with the terminals the unbalance is in the power supply – contact
power company.

TRANSFORMER SIZES
A full 3Ø supply is recommended for all 3Ø
motors, consisting of three individual transformers
or one 3Ø transformer. “Open” delta or wye connections using only two transformers can be used,
but are more likely to cause problems from current unbalance.

1. CentriPro 2-Wire motors have Generation 1 and Generation 2 amp ratings, see motor nameplate or motor data sticker that was supplied with motor.
2. Amps are higher than controller overload range - use of these motors will current limit and provide reduced performance.

Installation Steps:
1. Install the Pump
• Plumb suction and discharge of pump into piping.
• Install a check valve on the suction side.
• Locate the pump as near liquid source as possible.
2. Install the Pressure Transducer
• Install the pressure transducer in the tank tee provided with
the unit.
• Locate the transducer within 120” of the controller.
3. Mount the Controller
• Mount vertically in a well ventilated, shaded area with 8
inches of free air space on every side and temperature
between 34º F and 104º F.
4. Connect Input Power
• Connect the 1Ø power from a 20 amp 2-pole circuit breaker.
• Do not use GFCI protection with ABII as nuisance tripping
will result.
5. Output Power Connections
• Connect the output power leads from the controller to the 3
motor leads in the conduit box on the motor.
6. Set the motor Overload Switches (or dials, 3 and 5 HP)
• Complete systems have overloads pre-set at factory.
7. Set the Pressure - Factory pre-set is 50 PSI
• Push and Hold the Increase or Decrease Pressure Adjust
Pushbutton until the desired pressure setting is reached.
• The maximum allowable pressure setting is 85 psi.
8. Set the Application Switches (or dials, 3 and 5 HP)
• Minimum Speed of 10 Hz – the incoming pressure is within 20
PSI of the desired pressure setting.
• Minimum Speed of 30 Hz – the incoming pressure is 20 PSI or
more below the desired pressure, if pumping from a tank or if
drawing a suction lift.
• Ramp Speed – Slow - Low flow; Medium - Medium flow; Fast
- High flow

QUICK START GUIDE

QUICK START GUIDE
S-Drive Quick Start Up Guide
Step 1: Mount drive on secure wall or support beam using 4 screws.
Ensure drive is well ventilated. Leave at least 8” of free space
around the controller for cooling. Plug conduit holes not
used.
Step 2: Measure site voltage phase-phase and phase-ground; verify
incoming voltage is 1Ø or 3Ø 230V, or 3Ø 460V. make sure
all phase-ground voltages are equal. Models SPD2XXXX(F)
require 230V input voltage. Models SPD4XXXX(F) require
460V input voltage.
Step 3: Provide a dedicated fused disconnect (item #2 above) or
circuit breaker rated for drives input amps. No other equipment should be used for this disconnect. Use fast acting
class T fuses.
Step 4: Connect wire from input power supply to L1, L2, L3 and
GND. NOTE: For single phase supply power, wire to L1 and
L3 and adjust overload switches for 50% of drive current
rating. Ensure you have a solid ground from the building or
site. Ensure the ground is continuous between the service
entrance and the controller. Ensure there is at least 8” between the input wires and any other wires.
Step 5: Ensure you have a three phase motor. Connect motor leads
to T1/U, T2/V, T3/W and GND. Ensure the ground is continuous between the controller and the motor. For CentriPro
motors, connecting T1/U to Red, T2/V to Black and T3/W
to Yellow will give the correct rotation. To change rotation,
swap any two motor leads T1/U, T2/V or T3/W. Ensure there
is at least 8” between the output wires and any other wires.
Step 6: Plumb pressure transducer in straight piece of pipe downstream of last check valve in system. Do not install the pressure transducer or pressure tank where freezing can occur.
If pressure transducer is placed in grounded metal piping,
disconnect the drain wire in the pressure transducer cable
from the controller chassis.
Step 7: Pre-charge bladder tank to 10-15 PSI below your system
pressure. Tank capacity should be at least 20% volume of
maximum pump GPM.
Step 8: Set the Motor Overload Setting Switches. Choose a setting
that is equal to or less than the motor’s SFA rating.
Step 9: Factory pressure setting is 50 PSI when used with a 300PSI
transducer. Press and hold INC or DEC button to adjust pressure while pump is running. Ensure drive goes into stand-by
mode (solid green light/pump off) to save pressure setting.
NOTE: Do not connect power to CONTROL TERMINALS. Connect
only non-powered switch contacts to these terminals.
