Started filling CP3 @ 01:36, opened the exhaust check valve bypass valve, then opened LLCV bypass valve 1/2 turn, started to notice flow 29 seconds later. however I closed the LLCV bypass valve after allowing flow for a total of 2 minutes.
6 minutes later I closed the exhaust check valve bypass valve.
