Do not lay the cannula down while the concentrator is delivering oxygen. High
concentrations of oxygen can cause rapid burning.
NOTE– If the Service Required light illuminates and the audible signal alarms but the unit is
not operating, there is no power to the unit. Refer to the Minor Troubleshooting chart
on page 8 and contact your DeVilbiss provider if necessary.
NOTE– If an audible low-frequency vibration sound is detected, the unit is not operating
properly. Refer to the Minor Troubleshooting chart on page 8, and contact your
DeVilbiss provider if necessary.
2. Check the flow meter to make sure that the flow meter ball is centered on the line next to the
prescribed number of your flow rate.
CAUTION– It is very important to follow your oxygen prescription. Do not increase or
decrease the ow of oxygen – consult your physician.
NOTE– Your DeVilbiss provider may have preset the ow meter so that it can not be
adjusted.
NOTE– If the ow meter knob is turned clockwise, the ow decreases (and eventually will
shut off the oxygen ow). If the knob is turned counterclockwise, the ow increases.
NOTE– For prescriptions of 5 LPM, be sure the ball is centered on the 5 liter line; the ball
should not touch the red line. Setting the ow higher than 5 may cause the oxygen
purity level to drop.
NOTE– The low-ow alarm will activate if the ow meter ball is set below .3 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.
3. Your DeVilbiss concentrator is now ready for use, properly position the cannula or mask (Figure 6).
Allow 20 minutes for oxygen concentrator to reach stated performance.
DeVilbiss OSD
®
Operation
The OSD (Oxygen Sensing Device) is a device within your concentrator that monitors the oxygen
produced by your unit. When the unit is turned “On,” all four lights (Power, Service Required, Low
Oxygen, and Normal Oxygen) on the front panel will illuminate briefly. After a few seconds, only the
Power and Normal Oxygen lights will remain lit.
The OSD lights on the front panel are defined as follows:
• GreenNormalOxygenlight–acceptableoxygenlevel.
• YellowLowOxygenlight–belowanacceptableoxygenlevel.
If the oxygen purity falls below the acceptable level, the green Normal Oxygen light will shut off and the
yellow Low Oxygen light will illuminate. Switch to your reserve oxygen system. Refer to the Minor
Troubleshooting section in this guide on page 8 and contact your DeVilbiss provider.
As an added safety feature should the oxygen purity continue to drop, an intermittent audible signal will
sound. Contact your DeVilbiss provider immediately. Do not attempt any other maintenance.
reserVe oxygen system
As a precaution, your DeVilbiss provider may supply you with a reserve oxygen system. If your unit loses
electrical power or fails to operate correctly, the Patient Alert System will sound to signal you to switch to
your reserve oxygen system (if provided) and contact your DeVilbiss provider.
