Inline Pressure Boosting System
Re-calibration of Control Head:
There are times , especially after servicing, that the Inline 400 needs to be re-calibrated.
This is necessary in order to re-establish a reference point for the indication of flow. Follow
these procedures for Field Flow Calibration:
1. Before powering the unit on, verify there is no water flowing in the system. This will
ensure that the flow piston is in the fully seated (zero flow) position.
2. While holding down the push button on the status display, plug the units power
cord into the receptacle (or switch on breaker if hard-wired). Continue holding
down the button for five seconds until both the green and red LEDs blink, indicating
calibration is complete. Release the button and the red LED should come on solid,
indicating calibration was successful.
3. Open valves/taps to begin water flow and confirm unit is operating properly.
