Performance Verifi cation
Use following test steps to verify the manifold’s functional performance:
Remove manifold cover.
Before beginning the test, verify following:
If the manifold is not in use, close the 3/4” source shut-off valve.
Verify that the two right-side line regulator isolation valves are open and the two left-side line regulator isolation
valves are closed.
As a starting point for this procedure, set the manifold, so right bank is in use. If the right bank green LED is illumi-
nated, proceed to the next step. If the left bank green LED is illuminated, manually switch the manifold to the
right side by pressing the left switch on control board.
Verify that the right bank green LED “IN USE” and the left bank yellow “READY” lights are illuminated.
If the manifold is connected to a master alarm panel, verify the manifold switchover alarm is not activated.
If the manifold is equipped with a pilot regulator, verify the gauge on it reads 50 PSI.
Verify gauge reading for the “In-use” right bank regulator. If the pressure is not correct, refer to the bank regulator
pressure adjustment procedure.
Verify the line pressure gauge reading, If the pressure is not correct, refer to the line regulator pressure adjust-
ment procedure. Note the reading for later use.
Watch the pressure gauge readings of the right side bank regulator and the line pressure gauge for at least fi ve
minutes. Readings may be slightly higher without vent fl ow but verify the readings do not continue to increase.
Close all cylinders on the right side of the manifold. Use the bleed valve on the line regulator to slowly vent off
pressure until the right bank high pressure gauge drops. Verify the manifold, switches to left bank when the right
bank high pressure gauge drops below the specifi ed setting of the bank regulator.
Verify only the left bank Green LED “In-use” and the right bank Red “Empty” LED illuminates.
If the manifold is connected to a master alarm panel, verify that the switchover alarm is activated.
Close the right-side line regulator ball valves and open the left line regulator ball valves.
Slightly depress the bleed valve on the left line regulator to create a small fl ow of gas through manifold.
Verify the pressure gauge reading on the bank “In-use” regulator to see if it is set up as per the specifi ed pressure
setting. If the pressure is not correct, refer to the bank regulator pressure adjustment procedure.
