Check 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.
Check the humidifier bottle and tubing for blockages or restrictions.
Inspect the flow meter and verify that the ball is not at the bottom of the meter. If it is, turn
the knob to increase the flow. Replace the flow meter if necessary.
Check all internal tubing for leaks. Verify that there are no leaks and that all connections are
secure. Replace any tubing or parts if necessary.
Inspect the HEPA filter for a blockage. Replace if found to be clogged.
Verify that the compressor is operating properly. Replace the compressor if necessary.
Check 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.
Check the humidifier bottle and tubing for blockages or restrictions.
Verify that the concentrator is in a well-ventilated location and that air flow into the device
is not impeded.
Inspect the intake filter for a blockage. Replace if found to be clogged.
Inspect the HEPA filter for a blockage. Replace if found to be clogged.
Check all internal tubing for leaks. Verify that there are no leaks and that all connections are
secure. Replace any tubing or parts if necessary.
Verify the functionality and accuracy of the flow meter. Replace if necessary.
Check the outlet pressure. If it is out of the acceptable range, adjust or replace the regula-
tor.
Verify that the compressor is operating properly. Replace if necessary.
Inspect the intake filter for a blockage. Replace if found to be clogged.
Inspect the Bacteria filter for a blockage. Replace if found to be clogged.
Verify that the concentrator is in a well-ventilated location and that air flow into the device
is not impeded.
Check all internal tubing for leaks. Verify that there are no leaks and that all connections
are secure. Replace any tubing or parts if necessary.
Verify the operation of the 4-way solenoid valve. Replace if necessary.
Verify that the compressor is operating properly. Replace if necessary.
Replace the sieve beds assembly.
Verify that the concentrator is in a well-ventilated location and that air flow into the device
is not impeded.
Verify that the cooling fan is connected properly to the circuit board and check the continu-
ity of the connection. Replace the cooling fan if it is not functioning.
Check all internal tubing for leaks. Verify that there are no leaks and that all connections are
secure. Replace any tubing or parts if necessary.
Adjust the regulator.
Replace the regulator.
Replace the sieve beds assembly.
