UNPACKING AND SETUP
“Power” and “Normal Oxygen” lights will remain on.
NOTE– DeVilbiss recommends for optimal service life that the DeVilbiss
Oxygen Concentrator to be operated for at least 30 minutes after it is
powered on. Shorter periods of operation may affect the long term reliable
operation of the product.
4. Slowly turn the ow meter knob until the ow meter ball is centered on the
line next to the appropriate ow rate.
NOTE–When the ow meter knob is turned clockwise, the ow decreases
(and eventually will shut off the oxygen ow). When the knob is turned
counter-clockwise, the ow increases.
NOTE–Use low output ow meter (part #515LF-607) for ow rates under 1
lpm.
NOTE–The unit may require up to 20 minutes for the oxygen concentration
and ow rate to stabilize. The ow rate should be monitored and
readjusted if necessary.
5. The ow meter has a locking device. If it is necessary to preset and lock in
the prescribed ow rate, tighten the set screw located on the hex nut just
below the control knob using a 1/16" Allen bit. No adjustment can be made
without loosening the set screw.
6. The DeVilbiss oxygen concentrator is now ready for use.
