off the remote on/off switch depending on the mode of the oxygen
generator to stop it.
5. Close the manual valve for the oxygen sample to the oxygen
concentration monitoring board.
5.7 EXTENDED SHUTDOWN
To shutdown the oxygen generator for 24 hours or longer, complete all the steps in
Section 5.6 — Shutdown. In addition, perform the following steps:
1. Fully close all manual valves on the oxygen receiver to isolate the
oxygen in the oxygen receiver, to prevent the loss of pressure in the
oxygen receiver and enable a normal start-up.
2. Disconnect the power supply.
5.8 START-UP AFTER AN EXTENDED SHUTDOWN
After an extended shutdown or an unexpected shutdown, such as a loss of electrical
power, you must purge the oxygen receiver of any low concentration oxygen before
the oxygen generator can supply oxygen within concentration specications. To
purge the oxygen receiver, follow all the steps in Section 5.4 — Initial Start-Up.
Using the oxygen generator at ows higher than 15% above those
specied in Appendix A of this manual, will result in the likely
contamination of the molecular sieve beds. This damage is not
covered under the standard warranty.
