OPERATION
AUTO Mode
With the AUTO/MANUAL switch on the PSA module’s panel in the AUTO position,
the oxygen concentrator cycles on and off automatically based on oxygen demand.
When the PRODUCT PRESSURE gauge increases to the approximate pressure
switch maximum pressure specified in this instruction manual, oxygen production
stops after ten cycles and enters the Standby mode. At this stage, the blue indicator
light on the AUTO/MANUAL switch shuts off. When the pressure of the oxygen
coming out of the adsorber beds decreases to approximately the pressure switch
minimum pressure specified in this instruction manual, the oxygen concentrator
resumes oxygen production and the blue indicator light on the AUTO/MANUAL
switch illuminates. The AUTO mode enables the most energy-efficient operation of
the oxygen concentrator. Use the AUTO mode during normal operation and to shut
down the oxygen concentrator.
MANUAL Mode
With the AUTO/MANUAL switch on the oxygen concentrator control panel in the
MANUAL position, the oxygen concentrator cycles continuously, regardless of the
pressure fluctuations. Use the MANUAL mode during initial start-up or start-up after
an extended shutdown of the oxygen concentrator and, depending on the oxygen
flow, pressure, and purity requirements of your application, as directed by your
AirSep Corporation representative.
