GENERAL TROUBLESHOOTING
Before reviewing the Troubleshooting Chart, the following steps may be useful to isolate any
malfunctions:
1. Make sure all filters are clean.
2. Turn the unit on by pressing flow setting [2] if a FreeStyle, or flow setting [3] if a FreeStyle 5.
A brief, continuous alarm sounds to indicate that the unit has been turned on. Allow the
compressor to start-up and run for approximately ten seconds.
3. If a FreeStyle, activate the test mode by pressing flow settings [1] and [3] simultaneously for
ten seconds. If a FreeStyle 5, activate the test mode by pressing flow settings [1] and [5]
simultaneously for ten seconds.
4. Make sure that the unit is leak-free by testing all tubing connections and fittings with leak-
testing solution. Protect the circuit board from the solution, and start the leak test at the
compressor, following the air flow of the unit to the oxygen outlet. Repair all leaks by
tightening connections and fittings.
5. After five minutes, measure the oxygen concentration.
