To prevent damage to the pressure switch, do not force the
adjustment screws past their stopping points.
3) Set the AUTO/MAN switch on the oxygen generator control panel to AUTO.
4) Close the oxygen outlet valve on the oxygen receiver. (This valve controls
oxygen flow from the oxygen receiver to your application.)
5) Observe the AUTO/MAN switch. When the yellow indicator light on the switch
shuts off to indicate when the oxygen generator stops cycling, note the
pressure on the OXYGEN RECEIVER PRESSURE gauge. If the oxygen
generator continues to cycle after the timed five cycles and the yellow
indicator light remains illuminated when the oxygen receiver pressure
exceeds the pressure switch maximum set pressure, perform the step 8. If
the oxygen generator stops cycling at approximately the pressure switch
maximum set pressure (after the timed five cycles delay), perform the step 9.
Otherwise, perform step 6.
A cycle of the oxygen generator consists of the time taken by a
particular step (say pressurization of Bed A) to repeat itself.
6) Turn the high pressure adjustment screw ¼-turn clockwise to increase the
pressure setting.
7) Repeat step 5.
8) Turn the high pressure adjustment screw ¼-turn counterclockwise to
decrease the pressure setting.
If the oxygen generator stops cycling after the timed five cycles,
proceed to step 9. If the oxygen generator does not stop
cycling after five cycles, repeat step 8.
9) Open the oxygen vent valve on the oxygen receiver.
10) Observe the AUTO/MAN switch on the oxygen generator control panel. When
the yellow indicator light on the switch illuminates to indicate when the
oxygen generator starts to cycle, note the pressure on the OXYGEN
RECEIVER PRESSURE gauge. If the oxygen generator does not start to
cycle when the oxygen pressure in the oxygen receiver decreases below the
