General Malfunction
If a general malfunction of the FreeStyle 5 unit occurs, Two ½ second alarms
sound every 5 seconds, and the red
ALARM
light turns on. When this occurs,
oxygen concentration is outside specifications. The patient should change to
another source of oxygen and contact the Equipment Provider.
2.4 Oxygen Concentration Test and Specification
To ensure that FreeStyle 5’s oxygen output is within specification, you must
perform an oxygen concentration test. Test the unit upon delivery to a patient and
at periodic intervals. Equipment Providers, based upon their own expertise and
documentation, may establish and implement their own protocol to check oxygen
concentration.
1. Connect the FreeStyle 5 Oxygen Concentrator using an AirSep-supplied AC
adapter only (AirSep Part No.PW020-1) to a 100-240 volt, 50/60 Hz electrical
outlet.
2. Turn unit on by pressing setting 5 on keypad.
3. Simultaneously press and hold settings 1 and 5 for 10 seconds. After 10 seconds, the
alarm will sound and the LEDs above each flow setting will illuminate verifying auto pulse
mode.

4. Allow unit to warm-up for 2 minutes before recording oxygen concentration.
5. Connect a calibrated oxygen analyzer to the oxygen outlet and record the
unit’s concentration. The specification in test mode is 87% or higher.
