TEST RUNNING
If test running pump before installation:
1. Insure that the power supply corresponds with that
shown on the nameplate of the motor and control
box. (if required).
2. Install pump and components appropriate for the
test as shown in Fig. 1.
3. Make sure power supply is turned off and circuit
breaker or disconnect switch is open. Make
electrical connections appropriate to your motor as
shown in Fig. 2, 3 or 4.
4. THREE-PHASE UNIT - A three-phase motor
requires a magnetic starter equipped with quick-trip,
ambient compensated heaters of correct size for the
horsepower of the motor. To insure correct rotation
of three-phase units, brace pump shell securely and
apply power momentarily by snapping line switch
quickly on and off.

SUITABILITY OF WELL
Install the pump only in a well that has been properly
developed. Water from an undeveloped well often contains
an excessive amount of sand, dirt, and abrasives which
can damage the pump. Check that the well is large enough
to allow the pump to be set at the required depth. Do not
set the pump below the casing perforations or well screen
unless you make arrangements to ensure an adequate
flow of water over the motor for cooling purposes.
Determine the correct pump setting from the driller’s
record by taking into account the static water level and the
drawdown at the proposed pumping rate. Keep the pump
at least five feet from the bottom of a drilled well.
SPLICING THE POWER CABLE
Follow the instructions enclosed in the cable splicing
kit you purchase.
DROP PIPE
Drop pipe is recommended for suspending
submersible pumps into the well. Please refer to pipe
manufacturer for recommendations on depth and
pressure. Give special consideration to:
NOTICE: IT IS RECOMMENDED THAT STEEL CABLE
BE USED FOR THE PURPOSES OF SECURING THE
PUMP. 3/16" DIAMETER TO 1/4" DIAMETER BRAIDED
STEEL CABLE IS SUFFICIENT TO SUPPORT MOST
PUMP/MOTOR ASSEMBLIES. IT IS ALWAYS BEST
TO CONFIRM THAT THE PUMP/MOTOR ASSEMBLY
DOES NOT EXCEED THE MAXIMUM WEIGHT LIMIT
OF THE CABLE SELECTED.
2. Torque arrestor just above pump to prevent chafing
the cable when pump and pipe twist during the
starting and stopping cycle. (See Figure 1)
Take great care to keep pipes clean and free from
pebbles, scale and thread chips. Make sound, air-tight
connections at all fittings. Pipe sealant is recommended.
CHECK VALVES
It is recommended that one or more check valves
always be used in submersible pump installations. If
the pump does not have a built-in check valve, an inline
check valve should be installed in the discharge line
within 25 feet of the pump and below the draw down
level of the water supply. For deeper settings, check
valves should be installed per the manufacturer's
recommendations. More than one check valve is often
needed, but more than the recommended number of
check valves should not be used.
Swing type check valves are not acceptable and should
never be used with submersible motors/pumps. Swing
type check valves have a slower reaction time which
can cause water hammer (see next page). Internal
pump check valves or spring loaded check valves close
quickly and help eliminate water hammer.
NOTE: Only positive sealing check valves should be
used in submersible installations. Although drilling the
check valve or using drain-back check valves may
prevent back spinning, they create upthrust and water
hammer problems.
Check valves are used to hold pressure in the system
when the pump stops. They also prevent backspin,
water hammer and upthrust. Any of these can lead to
early pump or motor failure.
A. Backspin - With no check valve or a failed check
valve, the water in the drop pipe and the water in the
system can flow down the discharge pipe when the motor
stops. This can cause the pump to rotate in a reverse
direction. If the motor is started while it is backspinning,
1. A safety cable to prevent loss of pump if pipe
should break.

an excessive force is placed across the pump-motor
WARNING
assembly that can cause impeller damage, motor or
pump shaft breakage, excessive bearing wear, etc.
B. Upthrust - With no check valve, a leaking check
valve, or drilled check valve, the unit starts under a zero
head condition. This causes an uplifting or upthrust on
the impeller-shaft assembly in the pump. This upward
movement carries across the pump-motor coupling and
creates an upthrust condition in the motor. Repeated
upthrust can cause premature failure of both the pump
and the motor.
C. Water Hammer - If the lowest check valve is more than
30 feet above the standing (lowest static) water level, or a
lower check valve leaks and the check valve above holds,
a vacuum is created in the discharge piping. On the next
pump start, water moving at very high velocity fills the void
and strikes the closed check valve and the stationary water
in the pipe above it, causing a hydraulic shock. This shock
can split pipes, break joints and damage the pump and/
or motor. Water hammer can often be heard or felt. When
discovered, the system should be shut down and the pump
installer contacted to correct the problem.
REMOVABLE POPPET CHECK VALVE
Some submersible pumps are supplied with a
REMOVABLE check valve assembly for applications
where the pump can become air locked. If the pump is
supplied without a check valve, or if the check valve is
removed, a spring-loaded inline check valve should be
installed roughly 10 to 20 feet (3 to 6.09 meters) above
the pump. This allows for the repriming of the pump
after the pump has run out of water.
Fluid draining back through the pump
can cause the pump to rotate backwards. If pump/
motor starts during this time; damage to the pump
can occur.
The check valve can be removed with the use of the
T-Handle Poppet Wrench (part no. 23498207), ordered
separately, or, with standard needle nose pliers. The
poppet assembly is left hand threaded and is removed
by turning CLOCKWISE.
If reinstalling a Popppet Check Valve assembly, the
assembly should be tightened to 15 inch-pounds.

INSTALLATION OF PUMP, DROP PIPE, AND
ASSOCIATED EQUIPMENT
Fig. 1 illustrates a typical well installation showing inground components. Franklin recommends the following
procedure when installing the pump and drop pipe:
1. Prior to fastening the pump/motor assembly to
the drop pipe, confirm that the motor’s lead wires
are securely housed under lead guard which was
supplied with the pump. Fastening screws have been
provided for use during the lead guard’s installation.
2. Fasten the submersible cable to the drop pipe with
clamps or appropriate tape every 10 ft. (3m) to
prevent tangling and damage to the cable. The cable
must remain slack when using plastic drop pipe to
allow for stretching of pipe when installed in the well.
3. Take care not to scrape or pinch the submersible
cable against the well casing.
4. Use an ohmmeter or megger to make insulation and
continuity checks on the cable once the pump is
installed. This locates any fault in the cable.
5. Make sure system check valves are installed
properly. See previous sections of this manual for
further information on check valve placement, type,
and troubleshooting.
6. Install a torque arrestor just above the pump to
prevent chafing the cable when pump and pipe twist
during starting and stopping.
7. Attach a safety cable to pump to prevent loss of
pump if pipe should break.

SELECTED.
8. Place a sanitary well seal or pitless adapter with
an approved cover plate over top of well per
manufacturers recommendations.
9. Keep pump at least 5’ (1.5m) from bottom of well and
above well screen or casing perforations.

ELECTRICAL INFORMATION
1. Employ a licensed electrician to perform the
wiring. All wiring must be done in accordance with
applicable national and local electrical codes.
2. Check that the power supply corresponds with the
electrical rating of the submersible motor and the
control box(if required). Make sure that the control box
electrical rating matches the motor electrical rating.
3. Every installation requires a fused disconnect switch
or circuit breaker.
4. Every installation must be grounded. There must be
a reliable ground connection between the pump and
the distribution panel. The motor lead incorporates a
green grounding conductor.
5. Lightning arrestors are recommended for every
installation. All stainless steel, single phase motors
thru 5HP have built-in lightning arrestors. Any 6” motor
or 4”, 3-phase motor requires a separate lightning
arrestor installed as close to the wellhead as possible.
Install the arrestor in accordance with manufacturers
recommendations. A lightning arrestor provides
protection against induced voltage surges on
6. Mount the control box in an area protected from rain,
snow, direct sunlight or other high temperatures as
this may cause tripping of the overload protector.
Also protect the control box from extreme cold
(below 25oF/-32oC) as this may have adverse effects
on starting capacitor.
7. A two-wire pump does not require a motor control
box, since all electrical components are built inside
the motor. Fig. 2 shows a typical wiring diagram for
a two-wire installation.
8. A three-wire, single-phase pump requires a motor
control box incorporating overload relays. Fig. 3
shows a typical wiring diagram for a three-wire,
single-phase installation. Note that a magnetic
contactor must be used if the pressure switch
electrical rating is not sufficient to handle the
submersible motor electrical rating. The pressure
switch would then be incorporated into a pilot
circuit to control the magnetic contactor. Make
the connections at the control box in accordance
with the wiring diagram in the control box to avoid
damage to the motor.
9. A three-phase pump does not require a motor
control box . Fig. 4 shows a typical wiring diagram
for a 3-wire, three-phase installation. A magnetic
contractor with 3-leg protection having quick-trip
ambient compensated overload relays must be
used.

10. Use an ohmeter to make continuity and insulation
checks after the installation is completed.
11. Place the additional motor label with the pump label
and place both in the disconnect switch or circuit
breaker box for future reference.
WELL TEST
Check the pump and well performance before making
the final connection to the discharge system.
1. Install a gate valve on the end of the pipe. Partially
open the valve.
2. Start the pump.
3. Open valve gradually to give full flow.
4. If the discharge is not clear, let the pump run until
water clears. If water does not clear in 30 minutes,
stop the pump and take the necessary steps to
correct the condition. After the water has appeared
clear, check for sand by discharging into a clean
bucket or suitable container.
5. Close valve until maximum required system flow
rate is obtained (this should correspond to the cut-in
pressure of the pressure switch). Ensure that the
output of the pump at this setting is not greater
than the yield of the well. This can be checked by
monitoring the well drawdown level and ensuring
that the level is stable at the maximum required
system flow rate.
Never run pump unless it is
completely submerged in water. If run without
water, the pump and motor could be damaged.
Note also that air drawn into the pump can cause
an airlock under certain conditions.
LOW-YIELDING WELL
A low-yielding well exists when the output from the
pump is greater than the yield of the well. It can
reduce the water level to the suction screen so that
a mixture of air and water enters the pump. Pumping
may stop since the pump cannot generate pressure
with insufficient water. In this case, the column of water
already in the drop pipe holds the check valve closed
and an airlock may develop inside the pump. Because
the conditions ensure neither adequate lubrication of
the pump nor proper cooling for the motor, damage
can result if power is not cut off quickly. Use one or
more of the following methods to correct and/or protect
this installation.
1. Install additional length of drop pipe to place pump
lower in well if possible.
2. Install a Franklin Pumptec or similar electronic
drawdown sensor.
3. Install a floatless liquid level control. This device
consists of an electrical relay activated by currents
flowing through the ground-return circuits of
electrodes hung in the well. The lower (STOP)
electrode, just above the pump, ensures that the
water level can never be pumped down to the
suction screen. The upper (START) electrode, just
below the lowest static water level, ensures that
the pump can start again as soon as the well has
recovered. A floatless liquid level control works
in series with the pressure switch. Refer to the
manufacturers instructions provided with control.
4. Install a flow control valve in the discharge line
upstream from the pressure switch. This restricts
the output from the pump without affecting the rate
that water can be drawn from the pressure tank.
Nevertheless, a heavy demand for water could
empty the pressure tank, so a tank with a bonded
diaphragm, air cell, or water bag is recommended.
5. Install a smaller pump to avoid over pumping the
well. Have dealer size pump to the well yield.
6. Install a low-pressure cut-off switch. A low pressure
cut off switch, or a pressure switch with such an
arrangement built in, protects a shallow-well pump
from losing its prime, but it does not always provide
satisfactory protection to a submersible pump from
the effects of over pumping the well. This is because
it responds to a loss of pressure at the surface,
which may occur after an air lock has formed inside
the pump. We recommend either a floatless liquid
level control or a flow control valve, in that order,
in preference to a low-pressure cutoff switch as
protection against over pumping.

DISCHARGE PLUMBING
Fig. 1 illustrates a typical well installation showing
above ground components. Adhere to the following
items when installing the discharge plumbing.
1. Install an above ground check valve upstream from
the pressure switch.
2. Always install a pressure relief valve in the system.
The relief valve should be capable of discharging the
flow rate of the pump at the rated working pressure
of the pressure tank. Locate the relief valve close to
the pressure tank.
3. Install a pressure switch between the check valve
and the pressure tank. Refer to Fig. 2, 3, or 4 for
proper wiring connections of pressure switch.
4. Install a pressure tank as close as possible to
the pressure switch. Refer to manufacturer’s
recommendations for installation.
