Questions and answers
Just received 525DS . Machine has red light on and beeps occasionally. Can you help
The red "Service Required" light and beeping on the DeVilbiss 525DS machine indicate a problem that needs attention. Possible causes include:
1. The flow meter is not properly set. Ensure it is set to the prescribed number.
2. The air filter is blocked. Check and clean it if needed.
3. The exhaust is blocked. Ensure nothing is restricting the exhaust area.
If these steps do not resolve the issue, contact your DeVilbiss provider. Additionally, if the oxygen concentration drops below 60%, the red light and beeping alert will activate.
