On/Off Switch
The l/O power switch starts and stops the operation of the unit. The green indicator
light illuminates to indicate that the oxygen generator is receiving electrical power.
Auto/Manual Switch
The AUTO/MANUAL switch selects the operating mode for the oxygen generator.
In the AUTO position, the oxygen generator cycles on and off to meet oxygen
demand. In the MANUAL position, the oxygen generator cycles continuously. The
amber indicator light on the AUTO/MANUAL switch illuminates only when the
oxygen generator produces oxygen.
Manual Drain Button
The oxygen generator uses an automatic valve to periodically drain excess
moisture extracted from the feed air. The manual drain button allows you to
operate the automatic drain valve manually at any time during operation.
Hour Meter (Not available on AS-20 model)
The hour meter indicates the total number of hours the oxygen generator cycles.
FEED AIR PRESSURE Gauge (Not available on AS-450 — AS-1000 models)
The FEED AIR PRESSURE gauge indicates the pressure of the feed air as the air
enters the generator prior to the feed air regulator.
CYCLE PRESSURE Gauge (Not available on AS-450 — AS-1000 models)
The CYCLE PRESSURE gauge indicates the pressure of the feed air before the air
enters the adsorbers. The feed air regulator controls the pressure indicated on the
CYCLE PRESSURE gauge.
ADSORBER PRESSURE Gauges (AS-450 — AS-1000 models only)
The adsorber pressure gauges indicate the pressure in the two adsorbers.
OXYGEN RECEIVER PRESSURE Gauge
The OXYGEN RECEIVER PRESSURE gauge indicates the oxygen pressure in the
oxygen receiver.
