  If your DeVilbiss Medical Equipment unit isn't working, and all the lights are off while the power switch is on and the alert is pulsing, there might be a few reasons. First, ensure the power cord is properly inserted into the wall outlet, and check the mains connection on the back of the unit if it's a 230-volt model. Second, check your home circuit breaker and reset it if needed. If the issue continues, try a different wall outlet. Finally, press the concentrator circuit breaker reset button located below the power switch. If none of these steps work, contact your DeVilbiss provider.

  If the red service required light is illuminated on your DeVilbiss Medical Equipment, and an audible alert is sounding, there are several potential causes. Check the air filter and wash it if it's dirty. Ensure that nothing is blocking the exhaust area of the unit. Inspect the cannula, face mask, or oxygen tubing for blockages or defects; detach them to see if proper flow is restored, and clean or replace them if necessary. Also, detach the humidifier to check for proper flow, cleaning or replacing it if needed. Finally, ensure the flow meter is set to the prescribed flow rate. If these steps do not resolve the issue, contact your DeVilbiss provider.
