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 backflow 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.
