Inline Constant Pressure System
5
Constant Pressure Introduction
The Franklin Electric Inline System provides consistent water pressure regulation using advanced
electronics to drive the pump/motor according to the system’s real-time demand. The water
pressure demand is under constant monitoring through a highly accurate, heavy-duty, long-life
pressure sensor, which is included with and wired into the system at the time of installation. By
adjusting the pump/motor speed, the Inline System automatically reacts to any change in system
demand while maintaining a constant output pressure. The Inline System’s constant output
pressure should not uctuate more than a psi or two, even though the overall system’s water
ow requirement may change dramatically. For example, a small demand on the system, such as
a bathroom faucet, results in the motor/pump running at its lowest speed. As greater demands
are placed on the system, such as opening additional faucets or using appliances, the speed
increases accordingly to maintain the desired system pressure.
System Diagnostics
In addition to regulating pump pressure and accurately controlling motor operation, the Inline
System continuously monitors system performance and can detect a variety of abnormal
conditions. In many cases, the controller will compensate as needed to maintain continuous
system operation. But, if there is high risk of equipment damage, the controller will protect the
system by shutting itself down. To help identify that there is a problem with the system (which
includes incoming water and electricity from the utility company), the Inline System will display
that there is a fault condition. See Troubleshooting section for fault codes. If possible, the
controller will try to restart when the fault condition subsides.
Water Over-Temperature Shut-Off
In the event of inadequate water supply, such as closure of the incoming water supply or system
component failure, the unit has a potential to run continuously. This operation can allow for
heating of the water inside the Inline System. To reduce the amount of heating, Inline Systems are
equipped with a thermal cuto switch. See Troubleshooting section for fault codes. Once the Inline
System cools, the unit will automatically resume operation.
Thermal Temperature Limits:
Maximum shut-o temperature - 150 °F (65 °C)
Minimum reset temperature - 118 °F (48 °C )

Inline Constant Pressure System
INSTALLATION
Location of the Inline Constant Pressure System
Decide on a location for the pump installation that is suitable based on the enclosure rating of the
Inline System.
Liquid-tight conduit and ttings must be used to maintain NEMA 4 rating.
This equipment must not be used by children or persons with reduced
physical, sensory or mental abilities, or lacking in experience and
expertise, unless supervised or instructed. Children may not use the
equipment, nor may they play with the unit or in the immediate vicinity.
Choose a clean, well-ventilated location that provides protection from freezing, ooding, and
excessive heat. In addition, it should provide access for servicing and allow convenient draining of
the pump, tank, and service pipes. A prepared foundation is not essential, provided the surface is
hard and level. It can be mounted in any orientation depending on the space available.
Installation in direct sunlight can reduce system power and reduce
drive life.
Plumbing, Piping, and Hoses
In general, keep the suction and discharge lines as large as possible. Avoid using bends, elbows,
and ttings whenever possible. All suction connections must be airtight, so use pipe compound on
all threaded joints. Use a suction strainer when applicable to prevent solids and foreign matter from
being drawn into the pump.
Flow Capacity by Pipe Size
The minimum supply pipe diameter should be selected not to exceed a maximum water velocity of
8 ft/sec (2.4 m/s). Use the table below for selection of the proper supply pipe size.
Water Supply Requirement
The Inline System is not designed to draw/lift water from a source below the pumping unit. There is
not an incoming ow requirement, other than that the system needs to be supplied with a constant
supply of water to keep the unit completely full of water at all times. It is recommended that the
system be supplied with inlet line ¾" diameter or larger.

Incoming Pressure Requirement
The Inline System is designed to operate as low as 3 psi (0.2 bar) at minimum incoming pressures.
When used on a cistern, the incoming pressure requirement is waived, but a water level must be
maintained in the cistern to prevent a vortex from forming.
Failure to maintain incoming water may result in heating of water,
personal injury, pump damage and/or property damage.
Suction Piping
When the pump is located at a distance from the water source, the suction piping may have to be
increased in diameter to reduce friction loss. The friction loss in a system increases:
1. As the ow rate increases
2. As the piping size decreases
Refer to the included Inline System’s performance tables (Appendix 1) and friction loss tables
(Appendix 2) to determine the amount of head lost for a given application.
Discharge Pipe Sizes for Installation
When the pump is located at a distance from points of water use, it is necessary to increase the
discharge pipe size in order to reduce friction loss. The friction loss in a system increases:
1. As the ow rate increases
2. As the piping size decreases
Refer to the included Inline System’s performance tables (Appendix 1) and friction loss tables
(Appendix 2) to determine the amount of head lost for a given application.
Pressure Tank
The Inline System needs a small pressure tank placed on the pump outlet to maintain constant
pressure. The tank supplies water while the pump ramps up to speed and in circumstances where
only a small amount of water is required for a short period of time. In addition, the tank prevents
water hammer by acting as a system buer. This buer also helps to prevent pressure spikes
when there is a sudden change in demand.

on condition can heat the water in the pump, which may cause pump
failure, plumbing failure, and/or personal injury.
Failure to install a pressure tank will prevent the pump from shutting
o. FAILURE TO FOLLOW THIS WARNING may result in heating of
water, personal injury, pump damage, and/or property damage.
INSTALLATION
Notice: Read and Follow All Instructions
Hazardous voltage can shock, burn or cause death.
Improper wiring can result in permanent damage to the system. Pump
connection must comply with National Electric Code (NEC) or Canadian
Electric Code (CEC), and all applicable local codes.
If you are not sure of the proper electrical connections, employ a
competent electrician for the installation. This ensures the installation
complies with all noted electrical codes.
Disconnect power at electrical panel before making any electrical connections. Supply voltage
must be +/- 10% of Inline System nameplate voltage (230 V).
Low or high voltage can damage the Inline System and will void the warranty. Connect pump
to dedicated branch circuit with no other appliances on it.
Do not operate pump unless pump is grounded.
A fused disconnect switch or circuit breaker should be placed at or near the pump as required
by local electrical codes.
Installation Procedure Plumbing
1. Disconnect electrical power at the main breaker.
2. Drain the system (if applicable).
3. Mount the Inline System in the desired location using mounting screws. Screw locations are
shown in FIGURE 1. The Inline System may be installed in any orientation.

4. Install inlet and outlet plumbing and pressure tank as shown in FIGURE 2. A check valve
must be installed in the inlet and outlet plumbing. The outlet check valve should be between
the pump and the pressure tank to prevent the possibility of backow into public water
systems and to ensure proper system operation. The inlet check valve should be used when
no other backow prevention device is present. This inlet check valve should be installed
before the optional bypass loop if that plumbing is used. Franklin Electric recommends that
all system check valves be spring-loaded to provide best system performance. Be sure
to check all local plumbing codes to ensure that all requirements pertaining to backow
prevention are met.
Failure to install check valves properly may prevent the pump
from shutting o. FAILURE TO FOLLOW THIS WARNING may
result in heating of water, personal injury, pump damage, and/or
property damage.
5. Install the pressure sensors at the pressure tank tee downstream of the pressure tank. (The
pressure tank should be between the pressure sensor and the pump.) The pressure sensor
has a 1/4-18 National Pipe Thread (NPT) connection. The pressure sensor should not be
installed in an inverted orientation (upside down). Make sure the pressure sensor and tank
are not located more than 5 feet o the main piping.
6. Install a pressure relief valve downstream of the check valve. The discharge must be
plumbed to a drain rated for maximum pump output at relief pressure setting.

Inline Constant Pressure System
Typical Installation
The Inline System is designed to both increase a system’s incoming pressure and to provide the
system with constant pressure across all outlets. See FIGURE 2 for a graphical representation of
what a typical installation may look like.
*NOTICE: If system plumbing does not have a backow prevention device, a check valve is required on the
incoming water supply line.
NOTE: These optional components are shown in a typical installation diagram. They should be used at the
installer’s discretion as required for particular applications.
MOTOR OVERLOAD PROTECTION NOTE: The drive electronics provide motor overload protection by
preventing motor current from exceeding the maximum Service Factor Amps (SFA). Motor over-temperature
sensing is not provided by the drive.

Installation Procedure Wiring
1. Disconnect electrical power at the main breaker.
2. Verify that the dedicated branch circuit for the Inline System is equipped with a 15 amp
Listed fuse/Listed circuit breaker.
3. Remove the access panel of the Inline System by removing the four access panel screws as
shown in FIGURE 1.
4. For your convenience, the pressure sensor has been pre-wired inside the unit. The red and
black wires are attached to the pressure sensor inputs, and the white and green wires are
connected to the pressure shut-o sensor input (optional). See FIGURES 3 and 4 showing
the sensor connections.
5. If mounting or in wet environments, a liquid-tight conduit tting and liquid-tight conduit are
required (not supplied) to ensure that the enclosure maintains a watertight NEMA 4 rating.
Install the liquid-tight conduit tting into the conduit hole in front of the L1, L2 line connector
(FIGURE 3).
Serious or fatal electric shock may result from failure to connect the Inline System to the service entrance ground. Also ground
metal plumbing and all other metal near the Inline System. When grounding these components, use a wire no smaller than the
power supply wires from the circuit breaker to the Inline System. To reduce the risk of electric shock, disconnect power before
working on or around the water system.
CAPACITORS INSIDE THE INLINE SYSTEM CONTROLLER CAN STILL HOLD LETHAL VOLTAGE EVEN AFTER POWER HAS
BEEN DISCONNECTED. ALLOW 5 MINUTES FOR DANGEROUS INTERNAL VOLTAGE TO DISCHARGE BEFORE REMOVING
ACCESS PANEL.
This pump has not been investigated for use in swimming pool or marine areas.

should be tightened to a torque of 10 in-lbs (1.13 Nm).
10. Set the pressure tank pre-charge at 70% of the desired water pressure setting. To check the
tank’s pre-charge, depressurize the water system by opening a tap. Measure the tank pre-
charge with a pressure gauge at its ination valve and make the necessary adjustments.
OPERATION
Ratings
Maximum operating pressure should be limited to whatever level is
needed to protect the rest of the existing system plumbing. When
required, a pressure relief valve should be installed, and/or the optional
over pressure sensor can be used.
Maximum suction pressure is 70 psi (4.8 bar). Maximum water temperature is 104 °F (40 °C). Avoid
pumping abrasive or sandy water.
This pump has been evaluated for use with water only.
Priming
Never run the pump dry. Fill the suction pipe, pump, and discharge piping completely with water.
A typical installation will be supplied by either a tank or a pressurized water source, creating what
is known as ooded suction condition.

Starting
Close all system outlets, then slightly crack one system outlet to allow excess air to bleed out of
the system. Start the pump. Gradually, but immediately, begin opening the discharge valve to half
open. If after a few minutes of running you do not get water, repeat priming process (the pump
may be locked by excess air that is trapped in the unit). Once the pump is operating, fully open
the discharge valve and a system outlet, letting the pump operate until the water is running clear.
No further priming should be needed unless the pump is drained or there is a leak in the suction
plumbing.
Leaky Systems
Leaky water systems might keep the controller running due to the accurate pressure sensing
capability of the pressure sensor. Continuous running or starts and stops do not hurt the controller,
pump or motor. However, to reduce the on-time of the controller/pump/motor, a “Bump-Mode”
procedure is installed.
During low ow (or leaky) conditions, this feature periodically increases the speed of the pump
several psi above the set point and shuts o the pump. This adds some time to bleed o before
the system starts up again
Water Supply Shut-off
Remove power from the Inline System prior to shutting o the incoming water supply. When ready
to restart the system, rst turn the incoming water supply back on, then reapply electrical power to
the Inline System.
s WARNING
!
WARNING FAILURE TO FOLLOW THIS instruction may result in heating of water,
personal injury, pump damage, and/or property damage.
Pressure Drop
Although the pressure is constant at the pressure sensor, pressure drops may be noticeable
in other areas of the home when additional taps are opened. This is due to restrictions in the
plumbing and will be more pronounced the farther the taps are from the pressure sensor. This
would be true of any system, and if observed, should not be interpreted as a failure in the
performance of the Inline Constant Pressure System.
Adjusting the Pressure Sensor
The pressure sensor communicates the system pressure to the Inline Constant Pressure System.
The sensor is preset at the factory to 50 psi (3.4 bar), but can be adjusted by the installer using the
following procedure:
a. Remove the rubber end cap (FIGURE 4).
b. Using a 7/32" Allen wrench (provided), turn the adjusting screw clockwise to increase
pressure and counter-clockwise to decrease pressure. The adjustment range is between
25 and 80 psi (1.7 and 5.5 bar) (1/4 turn = approximately 3 psi (0.2 bar).
c. Replace the rubber end cap.
d. Cover the pressure sensor terminals with the rubber boot provided (FIGURE 4).

Inline Constant Pressure System
Adjusting Pump So System Demand Is Not More Than System Supply
Inline Systems are typically used to increase municipal water pressure anywhere from 10 psi
(0.7 bars) to 70 psi (4.8 bars) above what is being supplied by the water utility. For the pump to
operate properly as it boosts the municipal water to the desired pressure, a consistent and steady
ow of water is required. The system will fail prematurely if it is set to operate at a point beyond
what can be supplied.
Process To Ensure Pump Is Receiving Enough Water To Meet Demand
1. Install a shut-o valve in the plumbing near the discharge of the pump.
2. Close the valve, but make sure that the supply water is allowed to freely ow into the
pump without restriction.
3. Adjust system for maximum ow demand.
4. Turn on the pump, and begin opening the discharge’s shut-o valve.
5. Continue opening the discharge valve until a very distinct noise is heard coming from the
pump. This noise is called cavitation (which can destroy the pump over time), and will
sound like there is gravel inside the pump. STOP opening the discharge valve once
cavitation is heard.
6. Slowly close the discharge valve until the cavitation is no longer heard.
7. The pump is now adjusted so that the system demand will not exceed what
can be supplied.
8. If the supply pressure or water demand varies over time, this procedure may need to be
repeated to eliminate cavitation.
DRIVE DIP SWITCH OPTIONS
The Inline System is factory set to properly operate in most installations without needing any
adjustments or changes to the DIP switch settings. If changes are required, the following is a
description of what control logic changes will occur as a switch’s position is changed.
Serious or fatal electrical shock may result from contact with internal
electrical components. DO NOT, under any circumstances, attempt to
modify DIP switch settings until power has been removed and 5 minutes
have passed for internal voltages to discharge! Power must be removed
for DIP switch setting to take eect.

Underload Sensitivity Selection
The Inline System controller is congured at the factory to ensure detection of underload faults in
a wide variety of pumping applications. In rare cases, this trip level may result in nuisance faults. If
the underload switch is activated, it is best to observe the system’s behavior during the underload
condition to be sure it will perform as expected. Once the controller begins to regulate pressure,
check operation at several ow rates to make sure the default sensitivity does not induce nuisance
underload trips.
If it is necessary to adjust the underload sensitivity, remove power and allow the controller to
discharge. Wait 5 minutes to allow internal voltage to dissipate, locate the DIP switch bank.
Use a small screwdriver (provided) to move position 1 to “ON” as shown.
Steady Flow Selection
The Inline System is congured at the factory to ensure quick response to maintain constant
pressure. In rare cases (as with a water line tap before the pressure tank), the unit may need to
be adjusted to oer better control. If the unit is used on a system that has a water line tap before
the pressure tank or where audible speed variations of the pump can be heard, adjusting the
pressure control response time may be necessary. After enabling this feature, the installer should
check ow changes for possible overshoot. A larger pressure tank and/or wider margin between
regulation and valve pressure may be required as the steady ow feature reduces the controller’s
reaction time to sudden changes in ow.
If it is necessary to adjust the pressure control, remove power and allow the controller to
discharge. Wait 5 minutes to allow internal voltage to dissipate, locate the DIP switch bank.
Use a small screwdriver (provided) to move position 2 to “ON” as shown.
MAINTENANCE
Lubrication
The pump requires only water for lubrication and must never be run dry.
Before disconnecting pump, be sure fuse box
leads are disconnected or power is turned o.
After reassembling the pump, refer to priming
instructions before running.
Hazardous voltage can shock, burn or cause
death. Disconnect power to pump before
servicing unit.
Draining
NOTICE: Disconnecting the pump will not necessarily drain all other
parts of the piping system. If there are any concerns with the proper
procedure or necessity of draining the suction plumbing, contact a
water systems professional.
All piping and water tanks exposed to freezing weather should be drained. If there are any
concerns with the proper procedure to drain the system’s pressure tank, contact the tank
manufacturer for assistance.
