Initial Power-Up
11. Verify the following:
• Right bank Red “Empty” LED goes out
• Right bank Yellow “Ready” LED illuminates
• Right bank tank contents gauge reads cylinder pressure
12. Close left bank tank. Slightly press bleed valve located on the side of the line regulator. Verify the following:
• Left bank tank contents gauge drops slowly
• As left cylinder contents gauge is nearly depleted, the manifold changes over to the right bank
• After change-over, the left bank Green “In Use” LED goes out and Red “Empty” LED illuminates
• After change-over, the right bank Yellow “Ready” LED goes out and Green “In Use” LED illuminates
13. Slowly open one cylinder on the left side of the manifold and press the “Push to Reset” button
14. Verify the following:
• Left bank Red “Empty” LED goes out
• Left bank Yellow “Ready” LED illuminates
• Left bank cylinder contents gauge reads tank pressure
• If connected to a master alarm panel, “secondary supply” alarm is not activated
15. Close left and right side cylinders.
16. Record pressure readings of left and right bank tank contents gauges.
17. Wait 15 minutes.
18. Compare current readings of the left and right bank tank contents gauges to those recorded in step 16. If
there is a noticeable pressure change on either gauge, perform leak testing described in Testing For Leaks
(page 20).
19. Reinstall manifold control panel cover.
20. Slowly open all tanks on both banks of the manifold.
