Bank Regulator Pressure Adjustment
This procedure should only be performed if the bank regulator pressures are not within acceptable limits during
performance verification procedure or after installation of a new bank pressure regulator.
Base pressure setting is a mechanical adjustment controlled by the regulator’s internal adjusting spring and without
any dome bias pressure. Recommended settings are listed on page 18 in the Table under the heading of “Intermediate
Pressure - Ready Bank”. After the base pressure has been set, the pressure will be increased by the amount of dome bias
pressure applied.
Shut off all cylinders on both banks of the manifold.
Close the main supply source valve.
Using the control board switches, cycle the manifold from bank to bank to vent residual dome bias pressure.
Remove nylon tube, then using a 9/16” wrench remove pipe (quick connect) adaptor from the dome of bank
regulator(s) to be adjusted.
Depress bleed valves on both line regulators to relieve all pressure from the manifold.
“S-L-O-W-L-Y” open one cylinder on the side of manifold that needs adjustment. For example, if the right bank
regulator needs adjustment, open one cylinder on the right side of manifold.
Slightly vent off the pressure from the bleed valve to create a small flow of gas through the manifold.
Using a 7/32” Allen wrench through the hole of the dome/bell, set the bank regulator to the specified setting
(Intermediate Pressure - Ready Bank).
Close cylinder valves.
If the other bank regulator also needs to be adjusted, repeat steps 6 through 10.
Apply Teflon tape, reinstall the pipe (quick connect) adaptor on dome of bank regulator and reinstall nylon
tube.
“S-L-O-W-L-Y” open all cylinders on both manifold banks.
Open main supply source valve.
