Introduction
The Inline 400 is a simple to use “plug-and-play” water pressure booster system. At the heart of
this fully integrated booster system is a trusted Franklin Electric submersible pump and motor.
The unit’s control head is equipped with a Hall effect ow sensor, inlet/outlet pressure switches,
thermal overload switch, and a durable printed circuit board. Enhanced performance allows
versatility in residential applications and allows for easy installation (mounting either vertically
or horizontally) while also enabling the system to work with virtually any existing plumbing
conguration. NOTE: The Inline System has a Type 2 enclosure rated for indoor use only.
The Franklin Electric Inline System provides consistent pressure boosting using advanced
electronics to drive and control a standard Franklin Electric pump and motor according to the
pressure boosting demands of the application.

Mechanical Installation
Location:
Decide on an appropriate location for the pump installation that is suitable based on the INDOOR
enclosure rating of the Inline Pressure Boosting System. 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 housing, pressure tank, and
service pipe. (NOTE: Should the unlikely event of internal leakage occur, install the pump in such a
way that no considerable collateral damage can arise.)
Inline 400 Installation Orientation: (refer to Figure 1 if necessary)
It is preferred (for ease of priming) to install the Inline 400 unit in a VERTICAL orientation. The unit,
however, can be installed in the HORIZONTAL position as long as the Air-Bleed valve is facing
upwards.
In VERTICAL installations, the Inline 400 comes standard with the ow direction being from LEFT
to RIGHT when mounted vertically on a wall. This ow direction can be easily changed to RIGHT to
LEFT by removing the two head mounting bolts, rotating the pump 180 degrees, and re-installing
the head mounting bolts. It is then possible to remove the (6) Control Cap screws and rotate 180
degrees to place the Status Display in a viewable orientation. (note: be careful when rotating the
control cap as there is an electrical cable attached to the head.)

*It is recommended (where applicable) to install the Inline 400 pump
in PARALLEL with the incoming water supply. This will allow for a“ser-
vice bypass”so that the typical household can still utilize the incoming
water (albeit at a reduced pressure) if maintenance work is required.
This type of installation requires both ball valves and the check valve
be installed as shown above.

Inline 400 Typical Residential Installation:
The Inline Pressure Boosting System is designed to increase a system's usable pressure
whenever water is in use. Shown below is a diagram of the “required” and “recommended”
components of a typical pressure boosting application.
#System Component Description
APressure Tank
A bladder-type pressure tank is required (recommend 2 gallon
size) for proper control of the Inline 400. See "Frequently asked
Questions" section for more detail. It is important that a check
valve NOT be installed between the pump and the pressure tank.
BINLET Pressure Gauge An INLET pressure gauge is recommended for the purpose of
system setup, operation, and troubleshooting.
COUTLET Pressure Gauge An OUTLET pressure gauge is recommended for the purpose of
system setup, operation, and troubleshooting.
DOutlet Pressure Reducing Valve
(PRV)
This Inline 400 will boost a downstream pressure equal to
55 PSI + incoming PSI. If the discharge plumbing, xtures,
and appliances are not rated for these higher pressures, it is
recommended to install a PRV after the pressure tank to limit the
max downstream pressure.
EInlet Pressure Reducing Valve
(PRV)
This Inline 400 will not function if the incoming water pressure
is greater than 40 PSI. If the incoming supply is above 40 PSI, a
PRV may be installed on the inlet.
FOutlet Pressure Relief Valve
It is recommended to install a pressure relief valve in the
discharge plumbing in order to protect the downstream
components from abnormal pressure spikes that may occur in
certain applications. Make certain the valves discharge is directed
towards a drain appropriately sized for the max ow of the pump
system or incoming water supply.
GMounting Clearance
For ease of service, it is recommended to leave a clearance of
20 inches below the pump (for housing removal only). This can
be reduced if the unit is installed with the two plumbing unions
shown above. This would make it easy to remove the entire pump
from the system for servicing.

Inline 400 Installation Procedure (Plumbing):
1. Disconnect relevant electrical power at the main breaker.
2. Close all water supply valves necessary to turn off the incoming water supply. Carefully
drain the existing plumbing system of all water.
3. Mount the Inline Pressure Boosting System in the desired location using mounting screws
and mounting holes. The mounting screws are not included with the product. The Inline
Pressure Boosting System may be installed in a horizontal or vertical orientation but must
not be inverted or hung from a horizontal surface.
4. Install inlet and outlet plumbing and pressure tank as shown in Figure 1. The inlet and
outlet of the unit is marked with “INLET" and “OUTLET“ respectively. Unions should be
installed on the suction and discharge ends of the pump (use of PTFE thread sealant tape
is recommended over paste, do not overtighten). Internal check valves are provided on
both the suction and the discharge ends of the pump. These valves can help in preventing
backow. If the optional bypass loop is used, a check valve should also be installed
in the bypass (See Fig. 1). Be sure to check all local plumbing codes to ensure that all
requirements pertaining to backow prevention are met.
5. Install a pressure gauge on both the inlet and outlet pipes. These will be required in order to
properly adjust the system as well as aid in system troubleshooting.
6. Install the pressure tank downstream from the pump. The tank should be located within 5'
of the discharge of the pump. There should be no control/check valve between the pressure
tank and the Inline Pressure Boosting System.
7. 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 settings.
Inline 400 Installation Procedure (Electrical):
1. Employ a licensed electrician to perform the wiring. All wiring must be done in accordance
with applicable national and local electrical codes.
2. Disconnect electrical power at the main breaker.
3. Verify that the dedicated branch circuit for the Inline Pressure Boosting System is equipped
with a 15 amp circuit breaker.
4. Check that the power supply corresponds with the electrical rating of the Inline Pressure
Boosting System being installed. Supply voltage must be +/- 10% of the nameplate voltage.
5. Every installation must be grounded. There must be a reliable ground connection between
the pump and the distribution panel.
6. The Inline Pressure Boosting System comes with all internal connections prewired.
7. Unit should be plugged into an outlet that matches that of the unit purchased.
s WARNING
!
WARNING
The Inline Pressure Boosting System can develop very high pressure in some situations.
Always install a pressure relief valve able to pass full pump ow at 120 psi (6.9 bar). Install
the pressure relief valve near the pressure tank.
It might be necessary to install a pressure reducing valve to limit the potential boost. Install
the pressure reducing valve after the pressure tank.

Inline Pressure Boosting System
Plumbing Considerations for Priming Purposes:
The Inline 400 needs to be primed with water before it can function properly. There are two internal
non-return (check) valves built into the head of the unit that need to open during priming. This
requires that the priming water has an incoming pressure of 1.5 PSI minimum. This is especially
important if the application involves boosting water out of a shallow cistern. There are two simple
ways to accomplish this in the suction plumbing.
Inline 400 Priming:
Never run the pump dry. Fill the suction pipe, pump housing, 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
With the unit fully plumbed into the system, open the water supply valve and allow pressurized
water to ow through the unit. Place a small bucket under the Inline tank to capture water that is
expelled from the air-bleed during priming. With a small athead screwdriver, slowly open the air
bleed valve (located directly under the outlet) to allow air to exit the internal pump and tank. When
the valve stops sputtering and only a ne stream of water is being expelled, close the air bleed
valve. The unit is now primed and ready for operation.

PRIMING: 1.5PSI can be achieved on the
inlet by pouring water through a 3’ vertical
water column. Be sure to keep the inlet
valve closed and open the air-bleed valve
until all air is purged from unit.
PRIMING: Adequate inlet pressure/
ow can be achieved on the inlet by
connecting a garden hose to a tting
on the inlet side of the pump. Be sure
to keep the inlet valve closed , turn on
water supply, and open the air-bleed
valve until all air is purged from unit.
