PRODUCT INFORMATION
Description
Little Giant's constant pressure boosting solutions help alleviate the challenges with inade-
quate or low water pressure. The Inline 1100 provides continuous pressure for private wells
and municipal/city water systems or multi-family dwellings. It also can be used in sprinkler,
farming, and commercial washdown or water storage/cistern system applications. This
pre-packaged all-in-one system includes a pump, motor, drive, and pressure switch.
Inline Systems are typically used to increase municipal water pressure anywhere from 10 to
70 psi (0.7 to 4.8 bars) above what is being supplied by the water utility.
The 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 monitor-
ing through a highly accurate, heavy-duty, long-life pressure sensor, which is included with and wired into
the system at the time of installation.

INSTALLATION PLANNING
Minimum Pressure Tank and Supply Pipe Sizing
Check that the pressure tank pre-charge setting is 70% of the system pressure sensor 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 inflation valve and make the necessary
adjustments.
NOTE: Tank pre-charge should be maintained for optimum pressure regulation.
• For 12 gpm (45 lpm) flow or greater, minimum pressure tank size is 4 gallons (15 L);
• For less than 12 gpm (45 lpm) pressure tank can be reduced to a minimum of 2 gallons (7.5 L).
The system is designed to operate as low as 3 psi (0.2 bar) at minimum incoming pressures.
NOTE: 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.
Risk of bodily injury or damage to pump or other equipment.
• Failure to maintain incoming water may result in heating of water, personal injury, pump damage
and/or property damage.
• Pressure tank failure may prevent the pump from shutting off. 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 off.

Environmental Requirements
Decide on a location for the pump installation that is:
• on a hard, level surface
• suitable to the enclosure rating of the system
• clean and well-ventilated
• protected from freezing, flooding, and excessive heat
• accessible for servicing
• convenient for draining of the pump housing, tank, and service pipes
• as close as possible to water source to minimize suction piping length
NOTE: When the pump is located at a distance from the water source, the piping may have to be
increased in diameter.
NOTE: The system is not designed to draw/lift water from a source below the pumping unit. There is
not an incoming flow 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.

Physical Installation
NOTE: Refer to “Typical Installation” on page 6.
1. Disconnect electrical power at the main breaker.
2. Close all water supply valves necessary to turn off the incoming water supply.
3. Carefully drain the existing plumbing system of all water.
4. Mount the system using mounting screws.
• The system may be installed in any orientation.
5. Install inlet plumbing to the unit.
• Install a check valve in the inlet plumbing when no other backflow prevention device is present.
• If a bypass loop is used in the plumbing, install the check valve before it.
• It is recommended to supply the system with inlet line ¾-inch diameter or larger.
NOTE: It is recommended that all system check valves are spring-loaded.
6. Connect the piping.
• Keep the suction and discharge lines as large as possible.
• Avoid using bends, elbows, and fittings whenever possible.
• Ensure all suction connections are airtight.
• Use pipe joint compound or PTFE tape at all threaded connections.
• Use a suction strainer when applicable to prevent solids and foreign matter from being drawn into
the pump.
7. Install a check valve in the outlet plumbing between the pump and pressure tank.
8. Add a small pressure tank on the pump outlet to maintain constant pressure.
NOTE: The tank supplies water while the pump ramps up to speed and when only a small amount of
water is required for a short period of time. Tanks prevent water hammer and prevent pressure spikes
when there is a sudden change in demand.
9. Install a shut-off valve in the plumbing near the discharge of the pump.
10. Install the pressure sensors at the pressure tank tee downstream of the pressure tank.
• The pressure sensor has a 1/4-18 NPT connection.
• Install the pressure sensor in an inverted orientation (upside down).
• Mount the pressure sensor in a vertical position.
• Make sure the pressure sensor and tank are not located more than 5 feet off the main piping.
11. Install a pressure relief valve downstream of the check valve, near the pressure tank.
• Plumb this discharge to a drain rated for maximum pump output at relief pressure settings.
Risk of bodily injury, property damage, or damage to system by pressurized
fluids.
• A pressure relief valve rated to handle full pump flow at 100 psi (6.9 bar) should be installed in the
system to prevent personal injury or property damage.
Risk of damage to pump or other property.
• A missing, improperly installed, or malfunctioning check valve can cause a pump to short-cycle due
to back-flow of the pumped fluid from the discharge plumbing back into the basin, significantly
shortening the life of the pump.

OPERATION
Priming the System
10
OPERATION
By adjusting the pump/motor speed, the system automatically reacts to any change in system demand
while maintaining a constant output pressure. The system’s constant output pressure should not fluctuate
more than a psi or two, even though the overall system’s water flow requirement may change dramatically.
Maximum suction pressure is 70 psi (4.8 bar).
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.
Priming the System
1. Fill the suction pipe, pump, and discharge piping completely with water.
NOTE: If the system contains a tank or pressurized water source (creating a flooded suction condition),
this step may be unnecessary.
2. Close all system water outlets.
3. Slightly crack one system outlet to allow excess air to bleed out of the system.
4. Start the pump.
5. Slowly open the discharge valve to halfway.
6. If after a few minutes of running water does not appear, repeat priming process.
NOTE: The pump may be locked by excess air that is trapped in the unit.
7. Once the pump is operating, open the discharge valve and a system outlet fully, letting the pump oper-
ate until the water is running without any air sputtering.
NOTE: No further priming is necessary unless the pump is drained or a leak develops in the suction plumb-
ing.
Risk of bodily injury or damage to pump or other equipment.
• 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 switch can be used.
• Do not run pumps against a closed discharge, or at a system operating pressure above 145 psi (10
bar).
Risk of damage to pump or other equipment.
• The pump has been evaluated for use with water only.
• Do not run the pump dry, which can cause overheating and damage to the unit. This will void the
warranty.

OPERATION
Maximum Operating Temperature

Maximum Operating Temperature
Thermal Temperature Limits:
• Maximum water temperature: 104 °F (40 °C).
• Maximum shut-off temperature: 150 °F (65 °C)
• Minimum reset temperature: 118 °F (48 °C)
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 allows for heating of the water inside the
system. To reduce the amount of heating, the system is equipped with a thermal cutoff switch.
• Refer to “Troubleshooting” on page 14 for fault codes. Once the system cools, the unit will auto-
matically resume operation.
System Pressure Fluctuations
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 pro-
nounced the farther the taps are from the pressure sensor. This would be true of any system, and should not
be interpreted as a failure in the performance of the system. Refer to “Adjusting System Pressure” on
page 12.
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.
Status Display

DRIVE CONFIGURATION
Operation Testing
12
Operation Testing
IMPORTANT: For the pump to operate properly as it boosts water to the desired pressure, a consistent
and steady flow of water is required. The system will fail prematurely if it is set to operate at a point
beyond what can be supplied.
1. Close the shut-off valve near the discharge.
IMPORTANT: Make sure the supply water is allowed to freely flow into the pump without restriction.
2. Adjust system for maximum flow demand.
3. Turn on the pump.
4. Begin opening the shut-off valve.
5. Continue opening the discharge valve until cavitation is heard coming from the pump.
• Cavitation 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.
NOTE: The pump is now adjusted so that the system demand will not exceed what can be supplied. If
the supply pressure or water demand varies over time, this procedure may need to be repeated to elim-
inate cavitation.
DRIVE CONFIGURATION
Adjusting System Pressure
The pressure sensor communicates the pressure to the system. The sensor is factory set to 50 psi
(3.4 bar), but can be adjusted by performing the following:
1. Remove the rubber end cap.
2. Using a 7/32" Allen wrench (provided), turn the screw to adjust pressure
• Turn clockwise to increase pressure.
• Turn counter-clockwise to decrease pressure.
• The adjustment range is between 25 and 80 psi (1.7 and 5.5 bar).
•¼ turn = approximately 3 psi (0.2 bar).
3. Replace the rubber end cap.
4. Cover the pressure sensor terminals with the rubber boot provided.
Risk of bodily injury or damage to pump or other equipment.
• Never operate the pump with isolation valve closed.
Risk of severe injury or death by electrical shock.
• 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 effect.

MAINTENANCE
DIP Switch Settings
13
DIP Switch Settings
The system is factory set to operate in most installations without adjusting the DIP switch settings.
DIP SW1: Underload Sensitivity Selection
The system controller ensures 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, 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 flow rates to make sure
the default sensitivity does not induce nuisance underload trips.
To adjust the underload sensitivity:
1. Remove power and allow the controller to discharge.
2. Wait 5 minutes to allow internal voltage to dissipate.
3. Use a small screwdriver (provided) to move position 1 to “ON” as shown.
DIP SW2: Steady Flow Selection
The system ensures quick response to maintain constant pressure.
• 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, it may be necessary to adjust the pressure control
response time.
To adjust the pressure control:
1. Remove power and allow the controller to discharge.
2. Wait 5 minutes to allow internal voltage to dissipate.
3. Use a small screwdriver (provided) to move position 2 to “ON” as shown.
4. Check flow changes for possible overshoot.
NOTE: A larger pressure tank and/or wider margin between regulation and valve pressure may be
required as the steady flow feature reduces the controller’s reaction time to sudden changes in flow.
MAINTENANCE
Draining the System
Drain all systems, piping, and water tanks exposed to weather when freezing conditions are expected.
• Use the drain plug on the bottom of the unit to drain the disabled (powered off) system.
• 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
and the system’s pressure tank, contact a water systems professional.

Risk of bodily injury, electric shock, or property damage.
• Disconnect power to the unit before attempting to perform maintenance functions.
• All maintenance functions should be performed by a qualified service professional.
• Remove power from the system prior to shutting off the incoming water supply. When ready to
restart the system, first turn the incoming water supply back on, then reapply electrical power to the
system.

MAINTENANCE
Troubleshooting
14
Troubleshooting
Diagnostic Fault Codes
The 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 (including incoming water and electricity from the util-
ity company), the system will display that there is a fault condition.
Refer to “Status Display” on page 11. The LED flashes in a repetitive pattern representing operational state.
Count the repetitive flashes to determine which fault the unit is reporting.
Symptom Based Troubleshooting
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. How-
ever, to reduce the on-time of the controller/pump/motor, a “Bump-Mode” feature is installed.
During low flow (or leaky) conditions, this feature periodically increases the speed of the pump several psi
above the set point and shuts off the pump. This adds some time to bleed off before the system starts up
again.

INFORMACIÓN SOBRE EL PRODUCTO
Descripción
Las soluciones de aumento de presión constante de Little Giant ayudan a aliviar los problemas
que plantea una presión de agua inadecuada o baja. El Inline 1100 proporciona una presión
continua para pozos privados y sistemas de agua municipales/urbanos o viviendas plurifami-
liares. También puede utilizarse en aplicaciones de aspersión, agricultura y sistemas comercia-
les de lavado o almacenamiento/cisternas de agua. Este sistema multiuso prearmado incluye
una bomba, un motor, un accionador y un presostato.
Los sistemas Inline normalmente se usan para aumentar la presión del abastecimiento de agua municipal
entre 10 psi (0,7 bar) y 70 psi (4,8 bar) por arriba de la presión ofrecida por el sistema público.
El sistema proporciona una regulación constante de la presión del agua mediante un sistema electrónico
avanzado que acciona la bomba/motor en función de la demanda en tiempo real del sistema. La demanda
de presión de agua se monitorea constantemente con un sensor de presión robusto de alta precisión y gran
duración, que viene con el sistema y se conecta a él en el momento de la instalación.
Características
Configuración
• La velocidad de la bomba es controlada para ofrecer un excelente desempeño sin recargar el motor
• Partida del motor con poca tensión (partida suave)
• Operación silenciosa
• Proyecto de controlador único de bomba/motor/unidad
• Base compacta, 480 x 200 mm (19 x 8")
Funcionamiento
• Opera en una amplia gama de flujos, desde la succión inundada hasta 135 l/m (35 gpm).
• Exige una presión de entrada mínima de 3 psi (0,2 bar). Excepción: Las cisternas pueden ser de succión
inundada sin remolinos.
• La presión máxima del sistema es de 80psi con un sensor de presión estándar (rango de 25 a 80psi)
• La presión máxima del sistema es de 150psi con un accesorio opcional de sensor de alta presión (rango
de 75 a 150psi)
• Estructura de acero inoxidable en todas las superficies húmedas.
Protección
• Sin corriente de irrupción (corriente momentánea de partida)

PLANIFICACIÓN DE LA INSTALACIÓN
Tamaño mínimo del tanque de presión y la tubería de suministro
Compruebe que el ajuste de precarga del tanque de presión sea de 70% para el sensor de presión del sis-
tema.
• Para revisar la precarga del tanque, despresurice el sistema de agua abriendo un grifo.
• Mida la precarga del tanque con un manómetro en su válvula de inflado y haga los ajustes necesa-
rios.
NOTA: Revise la precarga del tanque regularmente para mantener la regulación ideal de la presión.
• Para un flujo de 45 l/min. (12 gpm) o más, el tamaño mínimo delt anque de presión es de 15 l 4 galo-
nes).
• Para menos de 12 gpm (45 lpm), el tanque de presión puede reducirse a un mínimo de 2 galones (7.5l).
El sistema está diseñado para funcionar con presiones de entrada mínimas de tan solo 3 psi (0.2 bares).
NOTA: Cuando se usa en una cisterna, la exigencia de presión de entrada oscila, pero se debe mantener
el nivel de agua de la cisterna para evitar que se formen remolinos.
Riesgo de lesiones corporales o daños a bomba o otros equipos.
• Si no mantiene el agua entrante puede causar calentamiento del agua, lesiones personales, daños a la bomba
y/o a la propiedad.
• La falla del tanque de presión puede impedir que la bomba se apague. Una condición de operación continua
puede calentar el agua de la bomba, lo cual puede causar fallas en la bomba, en la tubería, y/o lesiones perso-
nales.
• Si no instala un tanque de presión impedirá que la bomba se apague.
