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 unit's 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.
