UNPACKING AND SETUP
front panel will illuminate momentarily and an audible signal will briey
sound conrming that the LEDs and audible signal are functioning
properly. The unit will operate in “start up” mode with the Low Oxygen light
lit until oxygen stabilization is achieved, at which time the Normal Oxygen
light will come on and remain lit. The “start up” mode may take up to 15
minutes.
NOTE– DeVilbiss recommends for optimal service life that the Drive
DeVilbiss Oxygen Concentrator to be operated for at least 30 minutes
after it is powered on. Shorter periods of operation, operating in extreme
temperature/humidity conditions or in the presence of contaminates, and/
or handling and storage conditions outside those specied, 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– For prescriptions of 10 LPM, be sure the ball is centered on
the 10 liter line; the ball should not touch the red line. Setting the ow
higher than 10 may cause the oxygen purity level to drop.
NOTE– The low-ow alarm may activate if the ow meter ball is set
below 2 lpm. The unit will continue to run; however, the Service Required
light will come on accompanied by an audible alarm. Adjust the ow meter
to your prescribed ow.
NOTE– Do not use a low-output ow meter with this concentrator.
NOTE– The unit may require up to 15 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 Drive DeVilbiss oxygen concentrator is now ready for use.
