application.
6.2 Operation
The oxygen generator can be operated in auto or manual mode depending on the
requirements of your application. To use product oxygen that meets the
specifications for your model listed in the Appendix A of this instruction manual, set
the AUTO/MANUAL switch to AUTO to produce oxygen only during times of the

AS-A—AS-P Series Instruction Manual
Allow the oxygen generator to enter standby during shutdown
to ensure that the oxygen receiver contains oxygen at design
purity during the subsequent restart and also ensure that the
unit shuts down at the proper point in the cycle. Failure to wait
until the oxygen generator enters standby results in temporarily
reduced purity oxygen during the subsequent restart.
To perform a normal start-up, the oxygen generator first
requires a shutdown as described in Section 6.3 — Shutdown.
If the oxygen generator shuts down due to a power loss, follow
the procedure in Section 6.1 — Initial Start-Up to restart the
oxygen generator.
