3.1 General Installation Guidelines
• Inordertoavoidabrasiontothepowerandcontrol
cables, pad the top of the well casing (a rubber pad is
recommended) where the cable will pass over it; use
a cable reel for cable control.
• Theunitmustalwaysbeeasytorotateinthe
hoistinggear.
• Laypowerandcontrolcablesoutstraightonthe
ground (no loops) before installation. Guide cables
during lowering so that they are not stretched or
squeezed while pump is being installed. Make sure
that cable insulation is not nicked or damaged before
or during installation. Never use the electrical cables
to move the motor/pump.
• Thepumpandmotorareheavy.Makesurethatall
connections are secure and that the hoisting gear is
adequate to do the job before starting to lift pump.
Don’t stand under the unit. Don’t allow extra people
into the area while hoisting the unit.
• Ifmotororpump/motorunitareattachedtoa
supporting girder, do not remove girder until unit
isvertical.
• Installpumpatleast10’(3m)belowthelowestwater
level during pumping, but at least 6’ (2m) above the
bottom of the well.
• 6”motorscanbeoperatedinverticalorhorizontal
(when lead wire is at 12:00 position facing motor
flange) positions.
• 4”motorscanbeoperatedinverticalorhorizontal
positions. Note that the thrust bearing will have
shorter life in a non-vertical application. In such an
installation, keep frequency of starts to less than
10perday.
3.2 Proper Grounding
Hazardous voltage. Can shock, burn
or cause death. Installation or service to electrical
equipment should only be done by qualified electrician.
Control panels must be connected to supply ground
Proper grounding serves two main purposes:
1. It provides a path to ground in case of a ground-fault.
Otherwise the current would present a shock or
electrocution hazard.
2. It protects equipment from electrical surges.
Use wire the same size as, or larger than motor’s
current-carrying wires (consult Tables in the motor
section).
Installations must comply with the National Electric Code
as well as state and local codes.
All systems must have lightning (surge) protection with a
secure connection to ground.
An above ground lighting (surge) protection must be
grounded metal-to-metal and extend all the way to
the water bearing layer to be effective. Do not ground
the lightning (surge) protection to the supply ground
or to a ground rod as this will provide little or no surge
protection to the unit.
All motors are internally grounded and requires a 3 or
4-wire drop cable.
3.3 Corrosive Water and Ground
Some waters are corrosive, and can eventually corrode
the ground wire. If the installation uses a metal well
casing, any ground current will flow through it. In the
case of plastic piping and casing, the water column would
carry the current in a ground fault situation.
To prevent this, route the motor ground wire and the
motor power leads through a GFCI with a 10 mA set
point. In this way, the GFCI will trip when a ground fault
has occurred AND the motor ground wire is no longer
functional.
3.4 Check Valves
Check valve installation is necessary for proper pump
operation. The pump should have a check valve on its
discharge, or within 25 feet (7.62 m) of the pump. For very
deep wells, locate a check valve at least every 200 feet
(61m) vertical.
• Useonlyspringtypeorgravity-poppetcheck
valves. Swing type valves can cause water hammer
problems.
• Donotusedrain-backstylecheckvalves(drilled).
Check valves serve the following purposes:
• MaintainPressure:Withoutacheckvalve,thepump
has to start each cycle at zero head, and fill the drop
pipe. This creates upthrust in the motor, and would
eventually damage both the pump and motor.
• PreventWaterHammer:Iftwocheckvalvesareused,
and the lower one leaks, then a partial vacuum forms
in the pipe. When the pump next starts, the flow fills
the void area quickly, and creates a shock wave that
can break piping and damage the pump. If you get
water hammer on pump start, this may be the cause.
• PreventBack-Spin:Withoutafunctioningcheck
valve, upon shutoff, the water drains back through
the pump, and cause it to rotate backwards. This can
create excessive wear on the thrust bearing, and if the
pump restarts as water is flowing down the pipe, it
will put an excessive load on the system.

3.5 Start-Up
NOTICE: To avoid sand-locking pump, follow procedure
below when starting pump for the first time. NEVER start
a pump with discharge completely open unless you have
done this procedure first.
1. Connect a pipe elbow, a short length of pipe and a
gate valve to pump discharge at well head.
2. Make sure that controls will not be subjected to
extreme heat or excess moisture.
3. Make sure power is OFF. DO NOT START PUMP YET.
4. Set gate valve on discharge 1/3 open; start pump.
5 Keep gate valve at this setting while water pumps out
on ground. Let it run until water is clear of sand or
silt. (To check solids in water, fill a glass from pump
and let solids settle out).
6. When water is completely clear at 1/3 setting, open
gate valve to approximately two-thirds open and
repeatprocess.
7. When water is completely clear at 2/3 setting, open
gate valve completely and run pump until water is
completely clear.
8. Do not stop the pump until the water is clear.
Otherwise sand will accumulate in the pump stages
which may bind or freeze the pump.
9. Remove gate valve and make permanent installation.
NOTICE: The motor may draw higher than normal current
while the riser pipe is filling. After the riser pipe is full,
the amp draw should drop back to less than the allowed
current given on the motor nameplate.
When pump is in service, the amp draw must be
approximately equal to or lower than the service factor
amps given on the motor nameplate. If not, recheck
entire installation and electrical hook-up to find out why
amp draw is higher than normal.
Motor Torque
The motor exerts a strong torque force on the downpipe
and any other supporting structures when it starts. This
torque is usually in the direction that would unscrew
right-hand threads (the motor’s reaction movement is
clockwise as seen from above).
All pipe and pump joints must be tightened to safely
handle the starting torque. Tighten all threaded
joints to a minimum of 10 ft.-lb per horsepower.
i.e. 20 HP = 200ft.-lb; 50 HP = 500 ft.-lb.
Tack welding or strap welding may be required with
higher horsepower pumps.

4.1 Mixing Wire Size with Existing
Installation
Using two different cable sizes.
Sometimes conditions make it desirable to use more
than one size cable, such as replacing a pump in an
existinginstallation.
For example: Installing a pump with a 4”, 5 HP, 230
volt, single phase motor, with the motor setting at 370’
(112.8m) down the well and with 160’ (48.8m) of #8cable
buried between the service entrance and the wellhead.
In order to avoid replacing the buried cable, the question
is: What size cable is required in the well? Calculate
asfollows:
1. According to Table 5-9, a total of 326’ (112.8m) of #8
cable is the maximum length cable to power a 5HP
motor. The percent of this total that has been used
by the 160’ (48.8m) of cable in the buried run is:
160’ / 326’ = .49 or 49%.
2. With 49% of the allowable cable already used, 51%
of the total length is left for use in the well. To avoid
running a cable that is too small (gauge) and lowering
the voltage to the motor, we have to find a cable size
large enough so that 370’ (112.8m) is less than 51%
of the total length allowed for that size.
3. 370 ÷ 51% = 726 feet.
4. From Table 5-9 we find that the total allowable length
for #4 cable is 809’ (246.6 m).
This is longer than needed. Therefore, #4 cable can
be used for the 370’ (112.8m) of cable in the well.
Any combination of sizes can be used, provided that
the total percentage of the length of the two sizes of
cable is not less than 100% of the allowed lengths.
4.2 Wire Splicing
Splice wire to motor leads. Use only copper wire for
connections to pump motor and control box.
1. Taped splice (for larger wire sizes)
A. Stagger lead and wire length so that 2nd lead is
2” (50mm) longer than 1st lead and 3rd lead is
2”(50mm) longer than second.
B. Cut off power supply wire ends. Match colors
and lengths of wires to colors and lengths of
motorleads.
C. Trim insulation back 1/2” (13mm) from supply
wire and motor lead ends (Figure 4-2).
D. Insert motor lead ends and supply wire ends
into butt connectors. Match wire colors between
supply wires and motor leads.
E. Using crimping pliers, indent butt connector lugs
to attach wires (Figure 4-3).
F. Cut Scotchfil™ electrical insulation putty into
3 equal parts and form tightly around butt
connectors. Be sure Scotchfil overlaps insulated
part of wire.
G. Using #33 Scotch® tape, wrap each joint tightly;
cover wire for about 1-1/2” (38mm) on each side
of joint. Make four passes with the tape. When
finished you should have four layers of tape tightly
wrapped around the wire. Press edges of tape
firmly down against the wire (Figure 4-4).
NOTICE: Since tightly wound tape is the only means
of keeping water out of splice, efficiency of splice will
depend on care used in wrapping tape.
NOTICE: For wire sizes larger than No. 8 (7mm2), use
soldered joint rather than Scotchfil putty, Figure 4-5.

2. Heat shrink splice (For wire sizes #14, 12 and 10 AWG
(2, 3 and 5mm2):
A. Remove 3/8” (9.5mm) insulation from ends of
motor leads and power supply wires.
B. Put plastic heat shrink tubing over motor leads
between power supply and motor.
C. Match wire colors and lengths between power
supply and motor.
D. Insert supply wire and lead ends into butt
connector and crimp. Match wire colors
between power supply and motor. Pull leads to
checkconnections.
E. Center tubing over butt connector and apply heat
evenly with a torch (match or lighter will not
supply enough heat, Figure 4-6).
NOTICE: Keep torch moving. Too much concentrated heat
may damage tubing.
4.3 3-Phase Starters
Starters are used to start the motor by engaging contacts
that will energize each line simultaneously. The contacts
are closed when the coil is energized.
Figures 4-7 through 4-9 show three types of starters used
on the motors. The control device in the secondary circuit
is typically a pressure switch. Other control could be
provided by level control, timers or manual switches.
Line Voltage Control
This commonly-used control has a coil energized by line
voltage. The coil voltage matches the line voltage.
Low Voltage Control
This starter arrangement uses a transformer to allow
the coil to be energized by a lower voltage. Note that the
secondary circuit must be fused, and the coil sized for the
secondary voltage.
Separate Voltage Control
This arrangement uses power from a separate source to
energize the coil.

4.4 Checking Motor Rotation
To check rotation before the pump is installed, follow
thesesteps:
During testing or checking rotation (such as “bumping”
or “inching”) the number of “starts” should be limited to
3and total run time of less than 15 seconds.
Bumping must be done while motor is in horizontal
position and followed by a full 15 minute cooling-off
period before any additional “starts” are attempted.
Energize the motor
briefly, and observe the
direction of rotation.
It should be counter-
clockwise when viewed
from the pump (shaft)
end.
To check rotation after
the pump is installed:
NOTICE: NEVER
continuously operate a
pump with the discharge
valve completely closed
(dead head). This can overload the motor due to lack of
cooling, or destroy the pump and will void the warranty.
After energizing the motor, check the flow and pressure
of the pump to make sure that the motor is rotating in the
correct direction. To correct a wrong rotation, switch any
two of the three cable connections (three-phase motor
only). The setting that gives the most flow and pressure is
correct.
A cooling-off period of 15 minutes is required
betweenstarts.
Hazardous voltage. Disconnect power
before working on wiring.
Input voltage, current and insulation resistance values
should be recorded throughout the installation and
should be used for preventive maintenance.
4.5 3-Phase Current Balancing
Current Unbalance Test
Before checking for current unbalance, the pump must
be started, and rotation direction determined.
Determine current unbalance by measuring current in
each power lead. Measure current for all three possible
hookups (Figure 4-11). Use example and worksheet on
the Installation Checklist and Record in Section 12 to
calculate current unbalance on a three phase supply
system and retain for future reference.
NOTICE: Current unbalance between leads should not
exceed 5%. If unbalance cannot be corrected by rolling
the leads, locate the source of the unbalance.
Here is an example of current readings at maximum
pump loads on each leg of a three wire hookup. Make
calculations for all three possible hookups.
A. For each hookup, add the readings for the three legs.
B. Divide each total by three to get average amps.
C. For each hookup, find current value farthest from
average (Calculate the greatest current difference
from the average).
D. Divide this difference by the average and multiply by
100 to obtain the percentage of unbalance.
Use smallest percentage unbalance, in this case
Arrangement 2 (Table 4.1).
Us e the Current-Balance worksheet
located in the Installation Record
After trying all three lead hookups, if the reading furthest
from average continues to show on the same power lead,
most of the unbalance is coming from the power source.
Call the power company.
If the reading furthest from average changes leads as the
hookup changes (that is, stays with a particular motor
lead), most of the unbalance is on the motor side of the
starter. This could be caused by a damaged cable, leaking
splice, poor connection, or faulty motor winding.

4.6 Transformer Sizing
A full three-phase power supply is recommended
for all three-phase motors and may consist of three
individual transformers or one three-phase transformer.
“Open” delta or wye connections which use only two
transformers can be used, but are more likely to cause
unbalanced current problems. Transformer ratings
should be no smaller than listed in Table 4-2 for supply
power to the motor alone.
Transformers are rated by KVA capacity. This must be
high enough capacity for the motor being installed. If the
transformer capacity is too small, the motor will receive
reduced voltage and may be damaged.
Any other loads in the system would be in addition to the
motor alone.
Refer to Table 4-2. Note that the open delta configuration
can only use 87% of the rated power of the two
transformers.

Select a generator that can supply at least 65% of rated
voltage upon start-up of the motor.
The chart shows ratings of generators, both externally
and internally regulated. This chart is somewhat
conservative. Consult the generator manufacturer if you
are uncertain.

50 150.0 188.0 60.0 75.0
60 175.0 220.0 75.0 94.0
Frequency
It is highly important that the generator maintain
constant frequency (Hz), since the motor’s speed depends
uponfrequency.
A drop of just 1 to 2 Hz can noticeably lower pump
performance. An increase of 1 to 2 Hz can cause
overloadconditions.
Voltage Regulation
There is a significant difference in the performance of
internally and externally regulated generators.
An external regulator senses output voltage dips
and triggers an increase in the voltage output of the
generator.
An internal regulator, senses current and responds to
increased current by supplying more voltage.
Generator Operation
Start the generator before starting the pump motor.
The pump motor must be stopped before turning off
thegenerator.
If the generator runs out of fuel, and the pump is still
connected, it will put excess strain on the thrust bearings
as the generator slows.
Risk of electrocution. Use transfer
switches when the generator is used as a backup to the
power grid. Contact your power company or generator
manufacturer for proper use of standby or backup
generators.
4.8 Special Applications
Using Phase Converters
Phase converters allow three-phase motors to operate
from one-phase supply. Various styles of phase
converters are available. Many converters do not supply
a properly balanced voltage, and using these will void the
motor’s warranty unless approval is obtained first.
Guidelines For Phase Converters:
• Currentunbalancemustbelessthan5%.
• Convertertobesizedtoservicefactorcapacity
• Maintainmotorcoolingwithacoolingflowofatleast
3’ per second.
• Fusesandcircuitbreakersmustbetime-delaytype.
Motor Starting with Reduced Voltage
Starting a motor with full voltage will bring it to full speed
in less than 1/2 second. This can:
• Spiketheloadcurrent,causingbriefvoltagedipsin
other equipment.
• Over-stresspumpandpipingcomponentsbecauseof
high torque.
• Causewaterhammer.
Motor Starters (3-Phase Only)
Various types of motor starters are available.
Autotransformers are recommended because of reduced
current draw.
When motor starters are used, they should supply
a minimum of 55% of rated voltage for adequate
startingtorque.

5.1 Motor Inspection
Check the motor for damage in shipping.
Before installation, check the following.
• Checkoveralltools,especiallythehoistinggear,for
wear or damage before hoisting unit.
• Inspectthemotorcableforanynicksorcuts.
• Verifythatmotornameplatedatamatches
registration card information exactly.
• Verifythatmotornameplatevoltageiscorrectfor
available power supply voltage. Voltage must not vary
more than +/-10% from nameplate rated voltage.
• Verifythatthewelldiameterislargeenoughto
accommodate the motor/pump unit all the way to the
pump setting depth.
• Forinstallationswithtightwellcasings,makesure
that riser pipe flanges are recessed to protect
the power and control cables from abrasion and
squeezing during installation.
Heavy object. Lifting equipment must be
capable of lifting motor and attached equipment.
• Ifthetotallengthofthepumpmotorunit(without
any riser pipe) exceeds 10’ (3m), the unit must be
supported with a girder while hoisting. Do not remove
supporting girder until unit is standing vertically in the
hoist. Check for damage.
5.2 Testing
Insulation Resistance
To check for insulation resistance:
1. Disconnect power to the motor for this test.
2. Connect an Ohm meter (resistance in Ω) between the
power leads and the motor ground or well casing.
20KΩ Damaged motor, possible result of
lightning strike.
500KΩ Typical of older installed motor in well.
2 MΩ Newly installed motor
10 MΩ Used motor, measured outside of well
20 MΩ New motor without cable
5.3 Storage and Transportation
The motors are filled with a non-toxic, Propylene Glycol
and water solution to prevent damage from freezing
temperatures. The solution will prevent damage from
freezing temperatures to -40˚F (-40˚ C). Motors should
be stored in areas that do not go below this temperature.
The solution will become slushy between 0˚F (-17˚C) and
-40˚F (-40˚C) but no damage occurs. If this occurs, allow
the motor to sit in the well for several minutes before
operating.
Storage site should be clean, well vented, and cool.
Keep humidity at the storage site as low as possible.
Protect motor and cables from direct sunlight.
Protect power supply cables and control cables from
moisture by taping the cable ends with electrician’s tape.
Do not kink power supply or control cables.
Take care when moving unit (packed or unpacked) with
crane or hoisting gear not to knock it against walls, steel
structure, floors, etc. Do not drop motor.
Do not lift motor or motor/pump unit by power supply or
control cables.

SECTION 5: XE Series 4” Submersible Motors
5.8 4” Motor Overload Protection
Single Phase Motors
Single phase motors have overload protection either
in the motor or in the control box. Motors less than or
equal to 1HP have built-in protection. This automatic
protection will continue to cycle under a locked or stalled
rotorcondition.
Single phase motors larger than 1 HP use overload
protection located in the SMC (Submersible Motor
Controls) section. These are manual overloads and must
be manually reset if an overload condition occurs.
5.9 Motor Cooling
Pentek® 4” XE Series motors are designed to operate to a
maximum SF (Service Factor) horsepower in water up to
86° F (30° C).
4” motors: Minimum cooling water flow 3 HP and over
I.D of casing Flow GPM (LPM) required

10 50 (189)
12 80 (303)
14 110 (416)
16 150 (568)
If the flow is less than specified, a flow-inducer sleeve
can be installed, as shown in Figure 5-2. The sleeve will
act like a smaller casing size to force flow around the
motor to aidcooling.
5.10 Starting Frequency
Recommended motor starting frequency is shown
below. Motor, pressure switch, tank, and pump life may
be extended by limiting starts per hour and starts per
day. Proper tank sizing is critical to control pump cycle
times. Excessive or rapid cycling creates heat which can
prematurely damage motors, switches, andcontrols.
Motor Starting Frequency
HP Single Phase Three Phase
Starts/hr Starts/24hr Starts/hr Starts/24hr
1/2 thru 3/4 12.5 300 12.5 300
1 thru 5 4.2 100
7.5 thru 200 4.2 100
A one (1) minute minimum run time for pumps and motors up to 1.5HP and
two (2) minutes for 2HP and larger motors is recommended to dissipate heat
build-up from starting current.

6.2 Testing
ELECTRICAL
(See Table 1, Page 4, for Motor Electrical
Specifications)
1. Risk of electrical shock if the cable is
damaged. Inspect the motor cable for any nicks or
cuts. Do not use the motor cable to pull, lift, or
handle the motor. Protect the motor cable during
storage, handling, moving, and installation of the
motor.
2. Inspect the motor to determine that it is the correct
horsepower, voltage, and size for the job and that
there is no shipping damage. Verify that the motor
nameplate voltage matches the available power
supply voltage. The nameplate rated voltage must
not vary more than ± 10% from the power supply
voltage.
3. On all new installations and after the motor has
sat idle for a long period of time, check the motor’s
internal electrical resistance with a megohmmeter
with lead wires connected. Prior to installation, the
motor should have an insulation value of at least
500 megohms. After installation, the motor and
power cable should have a minimum insulation
value of 1 megohm. If the minimum values are
below the listed values, contact the factory before
starting the motor.
4. Fuses or circuit breakers and overload protection
are required. Fuses or circuit breakers and
overloads must be sized in accordance with National
Electrical Code (NEC) or Canadian Electrical Code
(CEC) requirements, as applicable, and with all
applicable local codes and ordinances. See
Section 6 for these specifications.
5. Wire and ground the motor in accordance with
National Electrical Code (NEC) or Canadian
Electrical Code (CEC) requirements, as applicable,
and with all applicable local codes and ordinances.
6.3 Storage and Drain/Fill Instructions
LIFTING
1. Heavy Object. Lifting equipment must be
capable of lifting motor and attached equipment. Check
over all tools, especially the hoisting gear, for wear or
damage before hoisting the unit.
2. If the total length of the pump and motor unit (without
any riser pipe attached) exceeds 10ft (3m), support the
unit with a girder while hoisting (see Figure 1). Do not
remove the supporting girder until the unit is standing
vertically in the hoist. Check for damage.

6.3 Storage and Drain/Fill Instructions
MOTOR STORAGE AND INSTALLATION
1. The motor is filled at the factory with anti-freeze
which will protect it in temperatures down to –22ºF
(-30ºC). Do not install, transport or store the motor
below these temperatures if the motor is filled. If
storage is necessary at temperatures below –22ºF
(-30ºC), drain the anti-freeze from the motor.
2. Verify that the motor is full before installing. If not, fill
it with clean water (see below). Installing a motor that
is not filled with liquid will void the warranty. Before
installation, check all water fill and drain plugs,
mounting bolts, and cable connections for tightness.
Refill the motor with clean water as follows:
A. Stand the motor on end (vertically) and remove the
fill plug with a 5mm hexagonal nut driver.
B. Turn the motor shaft by hand while rocking the
motor back and forth (see Figure 2).
C. Pour in clean water until the motor is as full as
possible.
D. Repeat the turning/rocking procedure.
E. Check the liquid level. If necessary, add more clean
water.
F. When the motor is full, re-install the fill plug.
Tighten it with the 5mm hexagonal nut driver.
Support motor while rocking to prevent motor
from falling over.
A. Rock motor
while turning
shaft.
B. Fill motor;
repeat rocking
and lling until
motor is full.
Figure 2: Rock Motor gently from side to side while
turning shaft by hand (A), then fill with clean water (B).
Repeat until full.
Less Than 10 Ft (3 M) 10 Ft (3M) or More 10 Ft (3M) or More
Support the pump and motor! Lack of support will destroy the motor!
Figure 1: When the pump and motor together
(without any riser pipe) are 10ft (3m) long or more,
support the assembly before lifting to avoid bending
it in the middle. Never try to lift the motor or pump
by the motor cables.

Figure 3: If flow past motor is less than .5 fps (0.15 mps),
install a flow inducer sleeve as shown. Flow must be at
least .5 fps (0.15 mps) for adequate motor cooling. The
flow inducer sleeve should not touch the side of the
motor.

6.3 Storage and Drain/Fill Instructions
NOTICE To avoid damaging the motor thrust bearing,
do not hammer on the shaft, coupling, or slinger. Check
the motor rotation by hand to make sure that it turns
freely.
1. To avoid damage to the motor diaphragm, make
sure that the bottom of the motor does not touch
the dirt or mud at the bottom of the well. Install the
motor at least 10’ above the well bottom.
2. To install the motor horizontally, lay it down with
the lead wires at 12 o’clock when you are facing
the motor shaft. To prevent any load on the shaft
and bearings and to avoid any damaging vibrations
to the motor, mount the motor solidly on the pump
end and make sure that the pump and motor are
accurately aligned.
3. Install the motor so that during operation water
flows past all parts of it at a rate of at least 0.5 fps
(0.15 mps). If the well will not provide this flow,
install a sleeve on the motor to channel water past
it (see Figure 3). Do not try to operate the motor in
mud or sand. To do so will damage the motor and
void the warranty.
4. Electrical connections: Connect the three motor
leads to the three hot motor leads (black, brown,
and blue) in the incoming cable. Connect the
ground wire (green and yellow) in accordance with
NEC or CEC requirements (as applicable) and in
accordance with all applicable local codes and
ordinances. Apply power momentarily to check
rotation. If the motor runs backwards, interchange
any two power leads to reverse direction of rotation.

SECTION 6: Pentek® 6” Submersible Motors
6.7 Overload Protection
Submersible motors must have Class 10 overload protection that will disconnect the power within 10 seconds in the
case of a locked rotor. To accomplish this, fixed-heater overloads are used. Refer to Section 10 for appropriate heaters.
The chart is based upon total line amps. Divide the motor amps by 1.732 when using a 6-lead motor with a Y-Delta
Starter. Notice: General Electric overload heaters are only usable with general electric overload relays. Do not adjust
relays to exceed nameplate amps.
6.8 Motor Cooling
Pentek 6” motors are designed for minimum water flow of 0.5 ft. /sec. past the motor. Maximum water temperature is
95° F (35° C).

If the flow is less than specified, a flow-inducer sleeve can be installed. This will act like a smaller casing size, and
force flow around the motor to aid cooling. Always use a flow-inducer sleeve when the pump is in open water.
6.9 Head Loss In Casing
Use the chart below to account for the head loss around the pump.
6.10 Starting Frequency
To extend the life of the pump motor and control, limit the number of starts
to 100 per 24 hours. If higher starting frequencies are necessary, consult
your factory. To prevent overheating, run motor for a minimum of two
minutes. For starting frequency, refer to section 5.10.

6.11 Troubleshooting
Pentek 6” Motors
34
SECTION 7: Hitachi® 6” and Larger Submersible Motors
7.1 Motor Inspection
The following conditions are stated to provide the owner
with a list of criteria for maximum motor life and to
assure motor warranty.
1. Maximum water temperature:
• A) 35°C (95°F): 6” (5~40HP) motors.
• B) 25°C (77°F): 6” (50,60HP), 8’’, 10”, 12’’ and 14”
motors
2. PH content of the water between: 6.5 -8
3. Maximum chlorine content: 500 PPM
• Maximum Sulfuric acid iron content: 15 PPM
• Maximum Fluorine content: 0.8 PPM
• Maximum Electric conductivity: 118 μMHO/INCH
4. Maximum sand content: 50 PPM
5. Proper approved three phase overload protection.
See Table 13.
6. Proper fusing for motor circuit protection.
See Table C.
7. Proper line voltage during running conditions:
60Hz: 460V, 230V ±10%
50Hz: 380V ±10%
at motor lead terminal. (Voltage drop of cable should
be considered by user.)
Combination of voltage and frequency variation:
±10% (sum of absolute values of voltage and
frequency)
Current unbalance between legs should not exceed
5% of the average.
8. Proper sizing of motor (current, thrust, voltage, etc.)
and a 10 feet clearance from the bottom of the well
are required.
9. In the case of horizontal installation, the motor is to
be rigidly aligned with the pump and firmly mounted
to prevent any load on the shaft and bearings and to
avoid any damaging vibrations to the motor.
10. The motor must always be immersed in water so that
a flow velocity of cooling water at a rate of 0.5 feet
per second flows past any and all parts of the motor.
The motor will not operate in mud or sand.
11. The power cables shall be sized large enough so
that at rated current there will be less than a 5%
voltage drop. See Table C. Cables must be waterproof
submersible type.
12. For 3ø motor a balanced and properly sized
transformer bank shall be provided. Improper
electrical supply (for example, phase converter.
V-connection transformer, etc.) or connections will
void the warranty
13. Single-phase protection is recommended for
protection of the installation. Any failure due to single
phasing of the incoming voltage causing the motor to
fail will void the warranty.
14. Surge suppressors are recommended in the interest
of protecting the control panel, as well a.s the
insulation system of the motor. Any motor failure
due to lightning or other Acts of God will void the
warranty.
15. Provide waterproof insulation splices between all
lead wires and well cables.
16. In the event that a reduced voltage starter is used to
start the motor, the following should be verified:
• Correct quick trip, class 10 or better, ambient
compensated overloads are incorporated.
• Proper short circuit protection is utilized.
• The torque required by the motor and pump package
is attainable by this type starter.
• The lead arrangement of the motor is acceptable with
the proposed starter load connections.
• Verify that if any time delay relays are used in
switching contactors in and out, that the time settings
do not exceed 2 seconds; this could damage the
motor.
• lf a manual auto transformer starter is used, voltage
should be minimum 60% of rated voltage, and
switched to “Run”condition within 2 seconds. Double
check Table B and C for correct protection.
17. Single-Phase Motors (5-15HP)
Proper connections and correct capacitors and
relays are necessary for single-phase motor starting
and running. Connection diagram: Sec Fig. 1.
Performance and recommendable capacitors: See
Table D.
7.2 Testing
1. Do not use lead wires to pull, lift or handle the motor.
The lead wires should be protected during storage,
handling, moving and installation of the motor. 2)
2. Inspect the motor to determine that it is the correct
HP, voltage and size for the job and that there is no
shipping damage.
3. The factory-installed water in the motor is supplied
with anti-freeze capable of temperatures to
0°C(-22°F). Do not install, transport or store below
these temperatures. If storage is necessary below
these temperatures, drain the water from the motor.
4. After long periods of idleness and on all new
installations, check the electrical resistance and
megger the motor with lead wires connected: see
table A. Prior to installation, the motor should have
an insulation value of at least 50 megohms. After
installation, motor and power cable should have a
minimum insulation value of 1 megohm. If minimum
values are not obtained, contact factory.

SECTION 7: Hitachi® 6” and Larger Submersible Motors
7.2 Testing
5. Verify motor is filled with clean water before
installing. The warranty is void if this is not done.
Also check the tightness of all water filling and drain
plugs, mounting bolts and cable connections.
6. Do not hammer the shaft, coupling or slinger since
this may damage the thrust bearing. Check the
rotation of the motor by hand to insure that it turns
freely.
7. Do not drop the bottom end of the motor in the dirt or
mud since this may plug up the diaphragm opening.
8. If motor is to be installed horizontal, make sure that
the lead wires are at the 12 o’clock position when
facing the motor shaft (in horizontal position).
NOTE:
There are no bearings that need oil or grease. The motor,
being inaccessible, should be monitored through its
electrical connections.
• A) Measure and record operating current and voltage.
• B) Measure and record the motor insulation
resistance. Any resistance of less than 50 megohm
(5,000,000) for a new motor should be evaluated or
checked further by a qualified service shop.
• Lightning arrestors and/or surge capacitors will help
prevent damage to the control box, cables, and motor.
• Single-phase protection will help in preventing motor
failure due to adverse incoming primary power.
• Based on the values obtained in A and B above and
the output flow rates and pressures of the pump,
a complete picture of total performance can be
obtained. This can be used to determine any pump
and motor maintenance and overhauling which might
be required.
• If the motor is to be stored, protect the unit from
freezing by storing in an area with a temperature
higher than -30°C (-22° F).
7.3 Storage and Drain Fill Instructions
1. After energizing the motor, check the flow and
pressure of the pump to make sure that the motor
is rotating in the correct direction. To correct a
wrong rotation, switch any two of the three cable
connections. (Three-phase motor only)
2. When starting the pump for the first time, inspect
the water for sand. If sand appears, then continue
to pump till the water clears up; otherwise, sand
will accumulate in the pump stages and will bind or
freeze the moving parts if water is allowed to flow
back down the well.
3. During testing or checking rotation (such as
“humping” or “inching”) the number of “starts”
should be limited to 3, followed by a full 15 minute
cooling-off period before any additional “starts’’
are attempted. Depending on the depth of the well
and/or method of checking, these rotational checks
or ‘’starts’’ may actually be full-fledged starts. If
this is the case, then a full cooling-off period of 15
minutes is required between this type of start.
4. For automatic (pilot device) operation, the motor
should be allowed to cool for 15 minutes between
starts.
5. Input voltage, current and insulation resistance
values should be recorded throughout the life of
the installation and should be used as a from of
preventive maintenance.

SECTION 7: Hitachi® 6” and Larger Submersible Motors
7.7 Overload Protection
Submersible motors must have Class 10 overload protection that will disconnect the power within 10 seconds in the
case of a locked rotor. To accomplish this, fixed-heater overloads are used. Refer to Section 10 for appropriate heaters.
The chart is based upon total line amps. Divide the motor amps by 1.732 when using a 6-lead motor with a Y-Delta
Starter. Notice: General Electric® overload heaters are only usable with General Electric overload relays. Do not adjust
relays to exceed nameplate amps.
7.8 Motor Cooling
Hitachi 6” motors are designed for minimum water flow of 0.5 ft. /sec. past the motor. Maximum water temperature is
95° F (35° C).

If the flow is less than specified, a flow-inducer sleeve can be installed. This will act like a smaller casing size, and
force flow around the motor to aid cooling. Always use a flow-inducer sleeve when the pump is in open water.
7.9 Head Loss In Casing
Use the chart below to account for the head loss around the pump.
7.10 Starting Frequency
To extend the life of the pump motor and control, limit the number of starts
to 100 per 24 hours. If higher starting frequencies are necessary, consult
your factory. To prevent overheating, run motor for a minimum of two
minutes. For starting frequency, refer to section 5.10.

SECTION 8: Pentek Intellidrive™ Variable Frequency Drives
Transducer
The Pentek Intellidrive uses a 4-20mA, 0-100PSI
pressure transducer to control motor speed (max
is 300 PSI transducer).
The transducer (see Figure 1) senses pressure
in the pipe and converts it to an electrical signal.
The Drive senses and processes the signal in the
PID (Proportional, Integration, Derivative) control.
When operating in AUTOSTART mode, the Drive
increases and decreases the speed of the pump
motor as needed to maintain constant pressure in
the piping system.
Keypad
The keypad programs the Drive, monitors the
status of the pump, and displays faults if they
occur. Each button has a unique function, as
described in Figure 2. The LCD display shows a
text display of the status of the Drive’s operation.
Other LEDs light up to indicate when certain
buttons are pressed or certain events occur.
Fan
The Drive uses a thermostatically controlled
internal fan which operates automatically when
necessary to cool the Drive components.

SECTION 8: Pentek Intellidrive™ Variable Frequency Drives
Figure 9 - Basic Wiring Connections for Startup
Wiring
To allow for ease of wiring, the enclosure
wiring area is free of electronics other than
the terminals. Conduit holes and knockouts
are located so that the wire can be fed straight
through to the connectors, with minimal bending.
The terminals accept 6-14 AWG wire.
Installations that require larger wire gauge than
6AWG will require an external junction box. Run
6AWG wire from the Drive into the junction box,
then make external connections with wire nuts to
appropriately sized wire.
NOTICE For convenience in wiring, the input and
motor terminals unplug from the box. Pull them
down to remove them for ease of access, as
shown in Figure 8.
Verify that the terminal connectors are completely
seated when you replace them. It is best practice
to connect all output wires (larger wire gauge)
first, then all input wires.
Pump Connections
If the Pentek Intellidrive is used with above ground
motors not rated for Variable Frequency Drive
use, maximize motor life by limiting lead length
to 25 ft. Refer to the pump owner’s manual, the
National Electrical Code, and local codes for
proper wire size.
The output of the Drive is single phase (2-wire or
3-wire) or 3-phase, depending on motor selection
during startup.
The output power terminals (motor wire
connections) are located on the lower right side of
the Drive and are labeled R (Red), Y (Yellow), and
B (Black). See Tables 2 through 6 for suggested
wiresizes.
NOTICE 2-wire 1-phase connect to Y + B, not R + B.
Feed the motor cable through the 3/4” conduit
hole on the bottom right side and into the
appropriate terminals. If the wire is large enough
to require a larger conduit hole, remove the
1-1/4” knockout and use the appropriate conduit
connections. Attach the motor ground wire to the
grounding screw, located to the upper right of the
terminal block. Attach the motor power wires to
the terminals as shown in Figure 9.
NOTICE Drive does not sense motor temperature
and will not protect motor from over heating.

Pressure Tank Recommendations
Minimum tank size is two gallons. Use a pre-
charged pressure tank with Drive, as shown in
Figure 1. The tank size must equal at least 20
percent of the pump’s rated flow in gallons per
minute (GPM), but cannot be less than two gallons
capacity. For example, a pump rated at 7GPM
would require a tank of two gallons capacity or
larger. A pump rated at 50 GPM would require a 10
gallon tank or larger. Tanks larger than 10gallons
can be used, but may require adjustment of Wake
Delayparameter.

NOTICE Set pressure tank’s pre-charge to 70
percent of the system operating pressure. When
using an external set point as well as an internal
set point, pre-charge tank to 70 percent of the
lower setpoint of the two. Some applications may
require a different percentage when determining
the setpoint.
Transducer Connections
A 0-100 PSI 4-20 mA transducer is provided
with Drive. Install the transducer downstream of
tank, as shown in Figure 1. Install transducer in
a tee in a straight section of pipe with at least 1
foot of straight pipe on each side of the tee (i.e.,
all fittings must be at least 1 foot away from
transducer).
Feed transducer cable through the open 1/2”
conduit hole on bottom of the Drive enclosure.
As shown in Figure 9, connect the red wire of the
transducer cable to AI+, connect black wire to AI–,
and connect the green cable shield to the metal
cable shield screw.
To connect the transducer wires:
1. Strip wire ½ inch
2. Push spring terminal up with finger or slotted
screwdriver
3. Insert wires from bottom
4. Release spring terminal
Input Power Connections
The input power terminals are located on the
lower left side and are marked L1 and L2 (see
Figure 9). There is a ground screw for the input
ground wire to the right of the connector (torque
to 10 in lb). Feed wire through the 3/4” conduit
hole on the bottom left side and into appropriate
terminals. If wire is large enough to require a
larger conduit hole, remove the 1-1/4” knockout
and use appropriate conduitconnections.
To determine the correct wire sizes for
installation, see Table 3.
NOTICE The Pentek Intellidrive only accepts 230V
single phase input power. If incoming power does
not match this, have a qualified electrician alter
supply voltage to 230V/1Ph before connecting it to
the Drive. See specifications ratings in Section 8.2.

SECTION 8: Pentek Intellidrive™ Variable Frequency Drives
Ensure that the cover is installed before operating
the
Pentek Intellidrive.
Most installations will only require the initial
startup settings. However, the installer may need
to set additional parameters. Information about
accessing all parameters, explanations of their
functions, and procedures for changing parameter
values, will be found later in this section.
1. Program the Drive: Apply power to the
Pentek Intellidrive. Setup Guide will appear in
the display. Follow keypress sequence shown in

Service Factor Amps
To maximize pump performance, be sure to
enter the correct Service Factor Amps (SF
Amps) in the
Pentek Intellidrive
.
• EnteringSFAmpshigher than the motor
rating lets the Drive supply more amps to the
motor than the motor is designed for and may
allow the motor to overheat (see Table 8).
• EnteringSF Ampslower than the motor
rating limits the output amps to less than
the motor is designed for and will reduce the
performance of the pump.
• Forany1-Phase3-Wiremotor,thecorrect
Service Factor Amp rating for the Drive is Cap
Start/Cap Run amps (see Table 8). This may
not match the motor nameplate, which (for a
Single Phase, 3-Wire motor) will generally be
Cap Start/ Induction Run Amps.
• Forany3-Phaseor1Phase,2-Wiremotor,
use the motor nameplate Service Factor
Amprating.
NOTICE
Pentek®
submersible motors may
differ from motors of the same horsepower
from other manufacturers. For 1-Phase,
3-Wire motors from all other submersible
motor manufacturers, enter the motor
manufacturer’s CS/CR service factor amps for
your motor. For 3-Phase or 2-Wire 1-Phase
motors, use the motor nameplate amp value.

The I/O terminals are located in the center of
the wiring compartment, as shown previously in
Figure9.
The Digital Input connections (I1 and I2) are used to
control the Drive based on the state of an external
device, such as a flow switch, moisture sensor,
alternator, or other device. Programming is needed
to activate any of these functions (see Table 9).
The Output Relay (O1) is used to control an external
device based on two states of Drive; either Running
the pump or Faulted. Programming is needed to
activate any of these functions (see Table 9).
Cable Installation
Three 1/2” conduit knockouts are provided on the
bottom of the Drive enclosure for the I/O wires.
Break out the closest 1/2” knockout and route the
wires through. Use a cord grip to prevent the wire
from rubbing and causing a short.
NOTICE Never run low voltage I/O wire through
the same conduit hole as the 230V input wires or
motor wires.
To connect the external wires to the terminals:
1. Strip wire ½ inch
2. Push spring terminal up with finger or slotted
screwdriver
3. Insert wires from bottom
4. Release spring terminal

RS-485 Communications
RS-485 is a US-based telecommunications
standard for binary serial communications
between devices. It is the protocol, or set of
specifications, that needs to be followed to allow
devices that implement the standard to speak
to each other. A fully compliant RS-485 port is
included in the Pentek Intellidrive system to
permit serial connections among more than two
devices on an RS-485 compliant network. Figure
19 shows two-wire connection to the Drive.

9.4 Wiring Connections
Three phase input power is connected to U1, V1, and W1.
If single phase input is used connect to U1 and W1. The
neutral and ground leads must be connected to drive
terminal PE. Motor leads are connected to U2, V2, and
W2. The motor ground must be connected to terminal
GND. For detailed instructions, see Owner’s Manual.
9.5 Transducer Connection
The Pentek® Assistant defaults to a 4-20mA transducer
connected to AI2. The transducer is used to provide
pressure feedback to the drive. Transducers offered
by Pentek have either a red or brown power lead. The
red or brown lead should be connected to the +24V
powerconnection.
Transducers offered by Pentek have either a blue or black
output lead. The blue or black lead should be connected
to terminal 5. The Pentek U17-1286R transducer utilizes
shielded cable. The bare lead may be covered with green
shrink-wrap tubing. The bare lead is cable shielding, and
should be connected to terminal 1. The translucent lead
is unused, and should be tied off andinsulated.

9.8 Helpful Hints
Alarm 2025 upon startup
This is a normal alarm, and occurs whenever motor data
is changed. The alarm shows for about 15 seconds while
the drive performs a motor calibration.
Fault 14 External Fault 1
External fault 1 is triggered when the VFD’s output
frequency exceeds motor nameplate frequency for more
than 10 seconds. The ON delay parameter controls
the time delay for this fault. If the system includes a
large tank, or requires more time to reach the setpoint,
increase parameter 1404 (PPC5) or 1806 (PPC3).
This fault is designed to protect against loss of prime,
broken shafts, etc. To disable this fault, adjust parameter
2002 Maximum speed, to the motor nameplate rpm.
Sleep
The Pentek drive monitors pump speed to determine
demand. The pump is shut off when the rpm goes below
parameter 4023: PID Sleep Level. Always set parameter
4023 high enough to trigger sleep mode during low
demand conditions. Note that the shut-off head at
parameter 4023: RPM, must be higher than the pressure
set-point.
The pressure setpoint can be determined by slowly
closing the discharge valve to confirm that the RPM
decreases to a level that triggers the sleep mode. The
discharge head can also be found by using the BEC2
program on the BEC2.net website.
Systems that use small tanks, or have a flat performance
curve, may cycle rapidly at intermediate flows. Correct
this by increasing Parameter 4024: PID Sleep Delay.
DO NOT increase parameter 4024 to a level that will
cause the pump to run with no demand. The water in the
pump can overheat.
Sleep Options
Other devices such as flow or float switches can be used
to trigger sleep mode. Parameter 4022 determines the
method to trigger sleep mode. These options can be used
for pump up, pump down, and other on/off applications.
Multiple Systems / Setpoints
The Pentek PPC Series Controller includes (2)
independent process control sets (groups 40 and 41).
Group 41 parameters can be selected using Digital Input
(DI3). When first set-up, groups 40 and 41 are identical.
A set can be changed later with parameters for a
secondprocess.
Constant Flow
After running the Pentek Assistant, the drive can be
configured for constant flow by adjusting parameters
4006: Units, and 4009: 100% Value.
Constant Flow Example 1:
Using a 4-20ma velocity meter with a range of
0 to 10 ft/sec. We want the display to be ft/sec.
Set 4006 to ft/sec
Set 4009 to 10
Constant Flow Example 2:
Same setup as example 1, but we have a 4” pipe and want
the display to be gpm.
Set 4006 to gpm
Set 4009 to 393 (this is the flow in a 4” pipe which results
in a 10 ft/sec velocity).
Constant Flow Example 3:
Using a 4-20ma flow meter with a range of 0 to 100 gpm.
We want the display to be gpm.
Set 4006 to gpm
Set 4009 to 100

9.10 Reactors And Filters
Variable frequency drives produce voltage spikes that are
a function of voltage rise-time and length of motor cable.
In extreme cases peak voltage may exceed three times
the nominal operating voltage.
Reactors
A reactor is a resistance and inductance device that
reduces voltage spikes. It does this by both increasing the
voltage rise-time and improving the impedance match of
the cable and motor.
Filters
A filter combines a reactor with a capacitor network. The
capacitors absorb a portion of the voltage spikes. This
further reduces the peak voltage seen at the motor.
When to Use a Reactor or Filter
The chart below is a general guideline when choosing
between using a filter or reactor.

9.9 PPC3 and PPC5 Tank Sizing
These instructions are only for systems that require
tanks. Pressure tanks are generally required to maintain
system pressure during periods of low or no demand.
Tank pre-charge must be less than the pressure set point
– wake up deviation.
Tank can be sized using Boyle’s law (V1 x P1 = V2 x P2).
Units are in gallons and PSI.
Typically tanks are sized for approximately 20% of pump
capacity. For example, a 150 gpm pump typically requires
30 gallon total tank size.

SECTION 10: PPX NEMA Pump Panels
10.1 Description
The PPX series of pump control panels consist of a
manually operated fusible disconnect switch and a
magnetic contactor with a solid-state overload housed
in a NEMA enclosure. The fusible disconnect switch
provides motor branch short-circuit protection. The
contactor is proven in field applications where wide
voltage fluctuations may occur. The overload relays
provide motor overload protection.
The rainproof enclosure allows all routine operations to
be performed from the outside without opening the door.
The fusible disconnect switch handle is mechanically
interlocked with the enclosure door to prevent opening
the door before the handle is moved to the OFF position.
For better access during repair or inspection, the cover
may be removed by lifting the door upward and outward.
A latch is provided to prop the door open on windy days.
The overload relay incorporates a dial for field adjustment
of tripping current.
Install in conformance with National Electrical Code
and all local codes. Branch circuit protection must be
provided.
These controllers have all components arranged for easy
access from the front. The circuits are relatively simple
and circuit components are selected for trouble-free
operation. Periodically, depending on the environment
and duty, the panel should be inspected and cleaned.
Inspect all devices for loose bolts and nuts.

SECTION 11: Submersible Motor Controls
11.1 How it Works
Submersible Motor Controls act as an above ground
control system for you submersible motor. They provide
easy access to the “brains” of your motor, so you can
monitor, adjust and perform maintenance without
removing the motor.
There are three main groups of motor controls. Each of
these controls has a slightly different function, although
all serve the main purpose of providing control for the
motor.
Capacitor Start / Induction Run (CSIR)
A CSIR control uses a starting capacitor and a switch.
When voltage is first applied, the switch is closed and
the start capacitor is in the circuit. This provides extra
torque to bring the motor up to speed. The switch is often
referred to as a potential relay. The relay’s coil senses
voltage across the windings. When the windings get
close to full speed, they magnetize the coil and physically
breaks the connection to the start windings. This takes
not only the start windings out of the circuit, but the
starting capacitor as well. The motor then runs on the
main winding alone.
Capacitor Start / Capacitor Run (CSCR)
A CSCR control functions very similar to a CSIR control
except that in addition to the starting capacitor, it also
uses a running capacitor. This allows the start winding
to act as an auxiliary winding during operation. This
smooths out operation of the motor and provides greater
efficiency and a reduction in vibration and noise.
Plus Series Controls
The Pentek® PLUS series controls combine a CSCR
design and a control circuit to provide not only starting
power to the motor, but a switch to turn the control
on and off. The switch takes the form of a magnetic
contactor that uses a coil that physically closes the
contacts when energized. The contactor allows the
installer to use a pressure switch with a lower current
rating, since it is not switching the full amperage of the
motor.
11.2 Specifications
All Pentek Submersible Motor Controls are rated for
Indoor or Outdoor use and employ NEMA 3R enclosures.
They are rain-tight and resistant to weathering
andcorrosion.

12.1 How They Work
Pentek® motor protectors are designed to protect single
phase pumps from dry run, dead head, jammed impeller,
and over & under voltage conditions.
A calibration adjustment allows the motor protector to
be calibrated to specific pumping applications, thereby
reducing the possibility of false or nuisance tripping. A
micro drive based voltage and current sensing circuit
monitors for power fluctuations, over-current, and under-
current conditions. When an abnormality, such as loss
of suction, is detected, the motor protector deactivates
its output relay and immediately disconnects the pump
motor. The motor protector then activates its user-
selectable “Restart Delay” (Dry run recovery) timer.
When the timer counts to zero or power is removed and
reapplied, the motor protector reactivates its output relay
and turns the pump back on.
An infrared LED communicates directly with a hand-held
diagnostics tool called the Informer (sold separately). The
Informer displays 16 parameters including calibration
point, trip point, running points, and last fault.
NOTICE: The use of flow restrictors or unusually high
head pressures at the time of calibration may interfere
with the detection of dead head conditions.
Motor Protection
88
SECTION 12: Motor Protective Devices - 50/60 Hz
12.3 Mounting And Installation
Mount the Pentek® Motor Protector in a convenient
location in or near the motor control panel. If the location
is wet or dusty, then the Pentek Motor Protector should
be mounted in a NEMA 3R, 4, or 12 enclosure.
12.4 Wiring Connections
1. Connect one line from the fused disconnect to the
Motor protector’s “L1 IN” terminal. Run a wire from
the “L1 OUT” terminal to the other in-line controls
such as a pressure or float switch. See Figure 10-1.
2. Connect the other line from the fused disconnect to
Motor Protector “L2 IN” terminal. Run a wire from the
“L2 OUT” terminal to the other in-line controls such
as pressure or float switches. See Figure 12-1.
NOTICE: The Motor Protector may not detect a dead head
(blocked pipe) condition on applications where the pump
is undersized for a given motor or flow restrictors are
used on high stage pumps or low yield wells.
Calibration/Settings
NOTICE: Calibrate the Motor Protector during normal
pumping conditions.
1. Turn the RESTART DELAY / CALIBRATION adjustment
fully counter-clockwise to the “CAL.” position.
2. Apply power to the Motor Protector. The pump motor
should be running at this point.
3. The Motor Protector is being calibrated when the
CAL. LIGHT turns on (approximately 5 seconds).
Within 10seconds, proceed to step 4.
4. Set the RESTART DELAY / CALIBRATION adjustment
to the desired Restart Delay (Dry Well Recovery Time).
If you leave the RESTART DELAY / CALIBRATION
adjustment in the “CAL.” position, the unit will trip
off and stay off. Turn the adjustment out of the “CAL.”
position to start the pump.
Manual Reset Mode: If the RESTART DELAY /
CALIBRATION adjustment is set to “RESET”, the Motor
protector is in Manual Reset mode. After the Motor
Protector shuts down due to a voltage or load problem,
the RESTART DELAY / CALIBRATION adjustment must be
rotated out of the “RESET” position to restart the pump.
NOTICE: Any restart delay can be by-passed by rotating
the RESTART DELAY / CALIBRATION adjustment to
the “RESET” position and back to the desired Restart
Delaysetting.
Rapid Cycling Protection: Rapid cycling is defined as
more than four restarts in a 60 second period. The Motor
Protector will lockout upon detecting a rapid cycling
condition until power is removed and re-applied to the
L1 IN and L2 IN terminals. See Diagnostics Table for
instructions to diagnose a rapid cycling fault.

Troubleshooting
13.1 Pump And Motor Problem Analysis
Problem Possible Cause Check And Restore
Pump Won’t Start. No voltage (check
with voltmeter).
Typically will be no
startupnoise.
1. Main power supply off.
2. Blown fuse or tripped circuit breaker.
3. Wiring damage, loose connection.
4. Burnt contactor points.
Locked pump. 1. Check for sand in system.
2. Crooked well (submersible)
Overloads Trip. Low or high voltage. 1. Check with voltmeter. (±10% of nameplate voltage). Request
power company correct problem.
2. Determine if wire size is correct for voltage and amperage.
Hi gh ambient
temperature or direct
sunlight.
1. Improve cooling for motor and controls.
2. Use ambient compensated overloads.
In correct pump sizing –
mismatched motor.
1. Check pump (gpm) make sure near B.E.P. - “Best Efficiency
Point”.
2. Recheck pump and motor model numbers prior to installation.
Keep a written record.
High cycling rate. 1. Pressure control equipment malfunction.
2. Hole in piping system.
3. Pressure/storage tank failure.
Damaged motor control. Check components per troubleshooting.
Fu ses Blow or
Breaker Trips.
Short or Ground. 1. Fuses give superior protection and should be used in preference
to circuit breakers when possible.
2. Inspect wiring for visible signs of heat damage (discoloration,
damage to insulation).
3. Disconnect power and check with ohmmeter or megohmmeter
toground.
Improper sizing. Consult manufacturer’s information / sizing chart for proper size
and replace as required.
Lo w or No Water
Production.
No rotation. 1. Motor not turning (see “Pump won’t start” above.
2. Broken shaft coupling. Ammeter will show “low” amps.
Restriction in piping. 1. Check valve sticking.
2. Check valve installed backward.
3. Broken check valve poppet or flapper lodged in piping system
downstream.
Plugged inlet. 1. Intake screen encrusted with minerals.
2. Insufficient clearance between pump and well casing for high
capacity pump. Calculate intake velocity and limit to less than
5feet per second.

13.5 Submersible Controls
Troubleshooting
Individual Component Diagnostics
Potential Relays
Using ohm meter - Coil Resistance (2 to 5) should
measure according to the specification printed on the
wiringdiagram.
Using ohm meter - Contact resistance (1 to 2)
should measure close to zero; higher values indicate
deterioration of the contacts.
When the SMC first starts a faint click should be heard
very shortly after the pump activates
Start Capacitor
Using a capacitor meter – measured capacitance should
be within +20% of the rating printed on the capacitor (or
consult parts list for ratings).
Using ohm meter – the meter should quickly show
low resistance (ohms) and move slowly to show higher
resistance. Resistance should not be zero or open.
Physical Inspection – A foul smell or a buildup of black
soot indicates that a start capacitor has vented usually
because of heat or prolonged use.
Run Capacitor
Using a capacitor meter – measured capacitance should
be within +/- 6% of the rating printed on the capacitor (or
consult parts list for ratings).
Using ohm meter – the meter should quickly show
low resistance (ohms) and move slowly to show higher
resistance. Resistance should not be zero or open.
Physical Inspection – Run capacitors have a built in
fail safe device that disconnects the capacitor in case
of overheat, in the case of such an event the capacitor
willbulge.
Overloads
Push overload to ensure that it is reset.
Using ohm meter – connection resistance should
measure close to zero.
Magnetic Contactor
Using ohm meter – Coil Resistance should measure per
specification on wiring diagram.
Using ohm meter – Resistance between T1 & L1 and T2 &
L2 should measure close to zero with contacts manually
closed. Greater values indicates degradation of contacts.
Physical Inspection – Contacts should be free to move up
and down.
Measurements while running
Small Box – Measurements cannot be taken while
running, line voltage can be monitored with the cover off,
by placing a voltmeter across L1 & L2. Winding resistance
can be taken while motor is connected and should
correspond to manufacturers specification.
Fatal electrical shock hazard. Only qualified
persons should perform the following procedure.
Medium and Large Box - To take measurements while
running, remove the cover. Turn on the pump and allow
to cycle as usual. L1 to L2 should measure 230V +/- 10%,
it should not dip during operation. A clamp-on ammeter
can be used to measure amp draw along any number
ofcircuits.
The larger yellow wire or main leads can be used to
measure amp draw of the system, draw should spike and
then come in less than 1 second. Orange lead amp draw
should start out high and then drop out to become zero. If
the reading stays high there is a relay problem.
The voltage between Red and Yellow should measure
approximately 330V - higher values indicate no load;
lower values indicate the motor (CSCR or PSC only) is
not up to speed. Note that winding resistance cannot be
measured while the motor is attached to the control box.

14.1 Installation Checklist
This checklist can be used to preview and verify steps
in the installation of Pentek® equipment. Refer to
appropriate section of the manual for more information.
Electrical Power
❏ Verify that the electrical service transformers KVA
rating is adequate per the Table 4-2.
❏ Verify that motor voltage and frequency on the
nameplate match the power supply voltage.
❏ Verify that fuse sizes are appropriate for the
installation
❏ Verify that the pump, casing and power supply are
allgrounded.
❏ Inspect lightning arrestors for proper sized wire and
grounding. Do not rely solely on a grounding rod in the
earth.
❏ Verify that the cable size from the power supply box
to the pump is the correct size. See tables in
section 5-4.
Motor
❏ Lead Condition.
❏ Check insulation resistance.
❏ Verify nameplate information for the service needed.
❏ Verify that the motor is correctly sized to pump.
❏ Verify that fuses, heaters and other electrical
components are appropriate for the amp load.
❏ Fluid level.
Pump and Motor Assembly
❏ Verify pump shaft rotation.
❏ Verify that the pump rating matches the
siterequirements.
❏ Visually inspect pump and motor for electrical lead
condition and splice condition.
Installation
❏ Verify that the pipe joints are tight.
❏ Verify that check valves have been installed.
❏ Verify that the cable is supported with straps or tape
at least every 10 feet (3.05 m).
❏ Pump cooling.
❏ Start the pump and observe any noise, vibration, leaks
or overheating.
❏ Verify that the pump performance is as specified,
that the electrical current is balanced and
withinspecifications.
Check Valves
Check valve installation is necessary for proper pump
operation. The pump should have a check valve on its
discharge, or within 25 feet (7.62 m) of the pump. For
very deep wells, locate a check valve at least every
200feet (61 m).
• DO NOTinstallthecheckvalvemidwaybetween
the pump and the ground surface. Vibration in the
piping will resonate and may damage or destroy the
piping or pump. Adjust check valve spacing to avoid a
mid-pointplacement.
• Useonlyspringtypecheckvalves.Swingtypevalves
can cause water hammer problems.
• Donotusedrain-backstylecheckvalves(drilled).
Check valves serve the following purposes:
• MaintainPressure:Withoutacheckvalve,thepump
has to start each cycle at zero head, and fill the down
pipe. This creates upthrust in the motor, and would
eventually damage both the pump and motor.
• PreventWaterHammer:Iftwocheckvalvesareused,
and the lower one leaks, then a partial vacuum forms
in the pipe. When the pump next starts, the flow fills
the void area quickly and creates a shock wave that
can break piping and damage the pump.
• PreventBack-Spin:Withoutafunctioningcheck
valve, upon shutoff, the water drains back through
the pump, and cause it to rotate backwards. This can
create excessive wear on the thrust bearing, and if the
pump restarts as water is flowing down the pipe, it
will put an excessive load on the pump.

14.3 Sizing Submersible Pump, Motor,
and Tanks
Sizing a Submersible Pump
The following steps should be taken relative to properly
sizing the system.
1. Determine gpm of system and well.
2. Size of well casing and type.
3. Determine service pressure requirements.
4. Determine voltage and phase.
5. Determine discharge pipe size.
6. Calculate friction head loss.
7. Determine (total discharge) head.
8. Select the submersible pump for the above criteria,
and appropriate controls for the pump.
9. Select the proper size tank for minimum one minute
pump run time.
10. For starting frequency, refer to Section 5.10.
11. Determine the distance from the service entrance
panel to the pump motor.
12. Determine the size wire required based on the motors
maximum load amps and the distance from the
service entrance to the motor.
14.4 How to Select the Correct
Pumping Equipment
103
SECTION 14: Appendix
The answer to four basic questions will help select the
proper pump.
1. What is the size of the well? The inside diameter of
the well must be known so that the proper size pump
and drop pipe can be determined.
2. What is the submergence?
The vertical distance
in feet from the pump to the water level while the
pump is operating (see Figure 12-1). If the pump is
installed away from the well and is on higher ground,
this elevation must also be included. This must not be
confused with the standing waterlevel.
3. What should the average discharge pressure be?
Usual average discharge pressure is 50lbs. – half way
between the 40 lbs. to 60 lbs. switch setting of most
water systems. More pressure is needed when the
tank is installed away from the pump and at a higher
level, or when house or yard fixtures are above the
pump and tank, and a larger pump must be used.
4. What capacity is required? The discharge capacity
of the pump in gallons per minute that is needed
for satisfactory service. The pump should have
enough capacity so that it can deliver the total water
requirement in 2 hours of continuous operation. See
Table 12-1 for average water requirements.
Installation Terminology
Standing or Static Water Level – distance from top of
well to natural water level when pump is not operating.
Drawdown Distance – distance water level drops while
pump is operating.
Drawdown or Pumping Water Level – standing water
level plus drawdown.
Submergence – distance submersible pump intake
screen is installed below drawdown level.
Elevation – vertical distance between top of well and
service inlet.
Pump Setting – distance from top of well to pump
inletscreen.
Service Pressure – pressure required (in PSI) at
serviceinlet.
Friction Loss –loss of pressure due to friction of water
flowing through pipe and fittings.
Head – discharge head (in feet) delivered when pump is
operating at desired capacity.
Horizontal Pipe Run – horizontal distance between
service inlet and well.
“Top of Well” also means “Pitless Adapter Level” or
wellexit.
“Service Inlet” also means “Storage Tank Inlet”.
Selecting a Pump
TIP: PSI can be converted to equivalent feet of head by
multiplying by 2.31.
i.e. 60 psi = 138.6 feet of head
To choose a motor for your submersible pump you first
must know:
• FlowrequiredinGallonsperMinute
• Totalhead(Pumpinglevel,frictionlosses
and service pressure required)
Friction loss must be calculated, and depends upon total
length, diameter and type of pipe plus additions for each
fitting (valves, elbows...) in the line.
Refer to the product catalog for friction loss charts.

EXAMPLE
Assume we want 16 GPM at 60 PSI from a pump
drawdown level (pumping level) 100 feet below the
serviceinlet.
We have a 35 foot horizontal run of 1 1/4” plastic pipe
with two gate valves and four 90° elbows.
To find the Friction losses we must refer to friction loss
charts for pipe and fittings.
We find:
• 135feetofpipeforthetotalpiperun(100+35).
• 10equivalentfeetofpipeforthegatevalves(2x5)
• 28equivalentfeetofpipefortheelbows(7x4)
Add these for the total equivalent length of pipe = 173
• Inthefrictionlosscharts,findthelossofheadfor
173feet of 1 1/4” pipe at 16 gpm. (3.96 per 100’) =3.96

Add: 7 Friction loss
100 Pumping level
139 60 PSI service pressure required (60
x2.31=138.6. Round to 139)
= 246 Total Dynamic Head.
From this sample curve we would choose the
11/2HPpump.
Locate a pump with a best efficiency point near the
desired flow rate (16 GPM) that meets the total head
requirements (246 TDH).
Selecting a pump in this manner gives you the most
efficient pump for your application.
14.5 Sizing Tanks
Tank should be sized to accomodate starting frequency in
Section 5.10.
Refer to the dealer catalog for tank selection. Otherwise,
the following procedure can be used.
Drawdown based on Boyle’s Law
Procedure:
1. Identify drawdown multiplier relating to
specific application.
2. Insert multiplier (X) into the following formula:
Pump GPM x Min Run Time = Minimum Tank
Multiplier (X) Capacity Required
Example: An example of a 20 GPM pump with a
minimum run time of 1 minute, installed on a
50-70 PSIG system pressure range:
20 GPM x 1 minute = 83.3 minimum U.S.
.24 (factor) gallon tank capacity
NOTICE: Drawdown will be affected by operating
temperature of the system, accuracy of the pressure
switch and gauge, the actual pre-charge pressure and the
rate offill.
