Should it be necessary to replace the bank regulator, it can be done while the manifold is in service. However, this should
only be done by qualified technicians experienced in servicing medical equipment.
1. Remove the two top screws at the base of the display board bracket and tilt back the display board assembly for
easy access to the union nuts that secure the bank regulator. (Follow the instructions on the label)
2. Close all cylinders on the side of the manifold where the bank regulator is to be replaced.
3. Ensure that the service bank is the reserve/secondary. If not, cycle the manifold from In Use to Reserve by using
the circuit board control switch to vent residual dome bias pressure.
4. Slowly break the 1-1/8” union(s) allowing gas to slowly vent out from both the inlet and outlet side of the bank
regulator.
5. Remove the nylon tube from the regulator dome.
6. Install the new bank regulator. (May require slight adjustment to the fittings on the regulator to align with the
secure fittings on the manifold).
7. Tighten union nut on the inlet and outlet of the new bank regulator.
8. Reinstall nylon tube.
9. Close the display board assembly and attach the bracket with the two screws.
10. Slowly open cylinders and set the bank regulator’s output pressure as described in Bank Regulator Pressure
Adjustment Procedure.
