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]. A brief, continuous alarm sounds

to indicate that the FreeStyle has been turned on. The compressor will start to

run, you must wait 10 seconds before proceeding to step 3.

3. Activate the test mode by pressing flow settings [1] and [ 3] simultaneously

for five 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 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.

6. Review the Troubleshooting Chart that follows to isolate and repair any other

malfunction.
