Inline Constant Pressure System

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.

Inline Constant Pressure System

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.

Pressure Tank Pre-charge (PSI)

The pressure tank pre-charge setting should be 70% of the system pressure sensor setting as

indicated in the preceeding table.

NOTE: Tank pre-charge should be maintained for optimum pressure regulation.

Pressure tank failure may prevent the pump from shutting o. A run-

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

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.
