SYMPTOM POSSIBLE CAUSE REMEDY
F Red Service Required light is on and an
intermittent audible signal is sounding. 1. Flow meter is not properly set. 1. Ensure the ow meter is properly set to the prescribed number.
2. Air lter is blocked. 2. Check the air lter. If the lter is dirty, wash it following the cleaning
instructions on page 5.
3. Exhaust is blocked. 3. Check the exhaust area; make sure there is nothing restricting the unit
exhaust.
If the above remedies do not work, contact your DeVilbiss provider.
G. If any other problems occur with your oxygen
concentrator. 1. Turn your unit “Off.” Switch to your reserve oxygen system, and contact
your DeVilbiss provider immediately.
