Verify that the line pressure gauge reading is same as in step 11. If the pressure is not correct, refer to the Line
regulator pressure adjustment procedure.
Watch the pressure gauge readings on the left bank regulator and the supply line for at least fi ve minutes to en-
sure the readings do not continue to increase.
Close all cylinders on the left side of the manifold. Depress the bleed valve slightly so that the left bank high pres-
sure gauge drops slowly. Verify that the manifold switches to the right bank when the left bank high pressure
gauge drops below the specifi ed setting of the bank regulator.
Verify only the right bank Green “In-use” LED and the left bank Red “Empty” illuminates.
Slowly open a cylinder on left side. Verify that the left bank Red “Empty” LED goes out and the left bank Yellow
“Ready” LED illuminates.
Open both the right side line regulator ball valves.
Close the left and right side cylinders.
Record the pressure readings of the left and right bank cylinder content gauges.
Verify after 15 minutes, the pressure reading on the gauges should remain the same.
Slowly open all cylinders on both banks of the manifold.
Using the switches on the circuit board, switch the manifold to the bank of cylinders with the least pressure.
Reinstall the manifold control panel cover.
Open the 3/4” source (line) shut-off valve.
