Today at 5 PM we replaced the east N2 cylinder. The east pressure was 500 and the west cylinder pressure was 1000. Since Steve's elogs say that the consumption can be as high as 800 per day we wanted to be safe.

  1. We closed the black valve before the regulator and closed the valve on the cylinder.
  2. We unscrewed the brass fill line to the cylinder.
  3. We unchained the cylinder and put in the dolly (and attached the chains on there).
  4. We rolled in a fresh cylinder from outside using the red dolly (it should have chains).
  5. We put it in place, hooked up the chains, and screwed on the brass nozzle with the large adjustable wrench (need to put a non-adjustable here).
  6. Opened up the cylinder valve.
  7. Opened up the black valve.
  8. New east pressure reading is 2500 PSI. Regulated N2 pressure is 68 PSI.

1) Checked the N2 pressures: the unregulated cylinder pressures are both around 1500 PSI. How long until they get to 1000?
