NOTE – Be sure to read all of the steps involved before beginning any of the procedures in this manual.
NOTE – After repairing or replacing a component, run the unit for 20 minutes and check the oxygen concentration.
CAUTION – When servicing the DeVilbiss 5 Liter Oxygen Concentrator, be absolutely certain that the correct tools
are used and that the parts are free of oil and grease or any material not compatible with oxygen. Teflon
recommended and must be applied to the male threads omitting the first thread to eliminate the possibility of tape
particles entering the oxygen system. LOX-8™ sealant may be used in place of Teflon tape.
