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. Set the unit’s ON/OFF switch to the ON position. If the unit does not turn on,
refer to the Troubleshooting Chart that follows.
3. Activate the test mode by inserting a paper clip through the hole marked “T” to the
right of the hour meter.
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 heat exchanger, following the air flow of the unit to the oxygen outlet. Repair
all leaks by tightening connections and fittings.
5. After three minutes, measure the oxygen concentration.
