Oxygen ConcentratorPN 14940837 B — 26Troubleshooting TableSymptom Possible Cause Corrective ActionNo Oxygen Flow1 Oxygen Tubing Kinked/Leak-ingCheck the nasal cannula and any extension tubing being used for kinks, blockages, or leaks.Verify that all tubing connections are secure. Replace and tubing if necessary.2 Humidifier Bottle Restriction(if used) Check the humidifier bottle and tubing for blockages or restrictions.3 Flow Meter Closed (off) Inspect the flow meter and verify that the ball is not at the bottom of the meter. If it is, turnthe knob to increase the flow. Replace the flow meter if necessary.4 Internal Tubing Kinked/Leak-ingCheck all internal tubing for leaks. Verify that there are no leaks and that all connections aresecure. Replace any tubing or parts if necessary.5 HEPA Filter Restriction Inspect the HEPA filter for a blockage. Replace if found to be clogged.6 Compressor Malfunction Verify that the compressor is operating properly. Replace the compressor if necessary.Low Or Fluctuat-ing Oxygen FlowRates1 Oxygen Tubing Kinked/Leak-ingCheck the nasal cannula and any extension tubing being used for kinks, blockages, or leaks.Verify that all tubing connections are secure. Replace any tubing if necessary.2 Humidifier Bottle Restriction(if used) Check the humidifier bottle and tubing for blockages or restrictions.3 Poor Concentrator Location Verify that the concentrator is in a well-ventilated location and that air flow into the deviceis not impeded.4 Intake Filter Restriction Inspect the intake filter for a blockage. Replace if found to be clogged.5 Bacteria Filter Restriction Inspect the HEPA filter for a blockage. Replace if found to be clogged.6 Internal Tubing Kinked/Leak-ingCheck all internal tubing for leaks. Verify that there are no leaks and that all connections aresecure. Replace any tubing or parts if necessary.7 Flow Meter Malfunction Verify the functionality and accuracy of the flow meter. Replace if necessary.8 Regulator Malfunction Check the outlet pressure. If it is out of the acceptable range, adjust or replace the regula-tor.9 Compressor Malfunction Verify that the compressor is operating properly. Replace if necessary.Low OxygenConcentration1 Intake Filter Restriction Inspect the intake filter for a blockage.
