What do I do if the oxygen flow meter is not working?

If the bead in the oxygen flow meter is not moving, follow the troubleshooting steps below:
  1. Turn on the unit
  2. Ensure the oxygen flow meter is fully open
  3. Attach external oxygen source 
  4. Gently knock on the oxygen flow meter
If the bead is still not properly moving up and down, you will need to check the tubing connection inside the unit
  1. Turn off unit and disconnect unit from power
  2. Open the unit
  3. Check to ensure the tubing is connected on the oxygen flow meter (see Internal Tube Connection video below)
  4. Check to ensure the tubing is connected to the oxygen port (see Internal Tube Connection video below)
  5. If the tubing is disconnected, reconnect tubing
  6. Close the unit and connect the unit to power
  7. Turn on the unit
  8. Ensure the oxygen flow meter is fully open
  9. Attach external oxygen source 
  10. Test that bead in the flow meter is now moving
