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
backflow. 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 backflow 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.

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 flow 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 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.
