Oxygen Concentration Test

CAIRE recommends testing the oxygen concentration at least once
every six months for non-OCSI units.
1. Plug the AC Power Cord into an electrical outlet, and turn
the power switch in the "ON" (I) position.
2. Allow the concentrator to run continuously for a minimum
of 10 minutes.
3. Disconnect the tubing and/or cannula from the outlet barb if
one is attached.
4. Turn the flow control knob to 5LPM
5. Connect a calibrated oxygen analyzer to the outlet barb.
6. Verify that this display reads between 87–95.5%.
• If the oxygen concentration is not between
87–95.5%, refer to the troubleshooting sec-
tion of this manual for "Low Oxygen Con-
centration."
Note:
• If the concentrator is alarming and the oxygen
concentration measured is greater than 85%,
replace the main PCB.
