Amico Dome Loaded Manifold CSA - Manual (Page 26)

26 Amico Pipeline
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 bend the display board assembly
back for easy access to the union nuts that secures the bank regulator. (Follow label instructions)
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. “S-L-O-W-L-Y” break the 1-1/8” union(s) allowing gas to “S-L-O-W-L-Y” vent out from both the inlet and outlet side
of the bank regulator.
5. Remove nylon tube from regulator dome.
6. Install new regulator 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 display board assembly and attach bracket with the 2 screws.
10. “S-L-O-W-L-Y” open cylinders and set bank regulator’s output pressure as described in Bank Regulator Pressure
Adjustment procedure.
Line Regulator Pressure Adjustment
This procedure should be performed if the line regulator pressure is not within acceptable limits during performance
verification procedure or after installation of a new line regulator.
1. With both the bank regulators supplying pressure, open only one ball valve on the inlet and outlet of the line
regulator to be adjusted.
2. Slightly open/depress the bleed valve on the side of the regulator to create a small flow of gas though the manifold.
3. Using the handle on the bonnet of the regulator, turn to adjust the pressure to the specified setting, as mentioned
on the cabinet door by observing the line gauge.
4. Repeat (steps 1-3) to adjust the other line regulator.
5. After adjusting the pressure to the specified setting open all ball valves and ensure the supply line remains open.
