Release the two latches on either side of the manifold control panel and remove the cover.
Verify the following:
• Both master valves located on both header bars are open
• All four line regulator isolation valves are open (handles in horizontal position)

Slowly open one tank on the left side of the manifold and press the “Push to reset” button between the bank indicators.
Verify the following:
• Left bank Red “Empty” LED goes out
• Left bank Yellow “Ready” LED illuminates
• Left bank cylinder contents gauge reads cylinder pressure
• If connected to a master alarm panel, “secondary supply” alarm is not activated
Close right bank cylinder. Slightly depress bleed valve located on the side of the regulator. Verify the following:
