1) Set the ON/OFF switch on the oxygen generator control panel to ON.
2) Open the front cover of the enclosure and locate the pressure switch. (See
Figure 7-1.)
Locate the two adjustment screws on top of the pressure switch. The
adjustment screw closest to the rear of the cabinet controls the high pressure
setting. The adjustment screw closest to the front of the cabinet controls the
low pressure setting. Use a ¼-inch wrench or screwdriver to make
adjustments.
3) Set the AUTO/MAN switch on the oxygen generator control panel to AUTO.
AS-20—1000 Instruction Manual
Use extreme caution when performing this procedure since it
requires removal of the front cover of the enclosure while the
unit receives electrical power.
Refer to Appendix D of this instruction manual for additional
information on the pressure switch.
The adjustment screw normally requires less than a ¼ turn.
Turn either the high or low adjustment screw ¼-turn clockwise
to increase its pressure setting. Turn either screw
counterclockwise to decrease its pressure setting.
To prevent damage to the pressure switch, do not force the
adjustment screws past their stopping points.
