I have been having a few issues with my HPR130XD stopping due to coolant flow issues. I have changes the filters which seems to have helped a bit but still get the occasional problem.
In the manual (Manual Gas - 806320 Rev. 2) on page 5-38 it shows how to check what the flow rate is by holding the power button in and that the reading must be a minimum of 2.3 lpm (0.6 gpm).
However whenever the machine is working OK, when I hold the button in I get a reading of around 112 which does not seem to relate to this required flow rate so I was wondering what units this 112 is measuring.
