DEVILBISS OXYGEN CONCENTRATORS WITH OSD ONLY
The OSD (Oxygen Sensing Device) is a device within your concentrator that monitors the oxy-
gen 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 OSD Troubleshooting section in this guide on page 8 and contact your
Sunrise Medical/DeVilbiss provider.
As an added safety feature should the oxygen purity continue to drop, an intermittent audible
signal will sound. Contact your Sunrise Medical/DeVilbiss provider immediately. Do not
attempt any other maintenance.
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 Sunrise Medical/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 Sunrise
Medical/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 flow of oxygen– consult your physician.
NOTE– Your Sunrise Medical/DeVilbiss provider may have preset the flow meter so that it can
not be adjusted.
NOTE– If the flow meter knob is turned clockwise, the flow decreases (and eventually will
shut off the oxygen flow). If the knob is turned counterclockwise, the flow increases.
NOTE– The low-flow alarm will activate if the flow meter ball is set below 0.3 lpm. The unit
will continue to run; however, the Service Required light will come on accompanied by
an audible alarm. Adjust the flow meter to your prescribed flow.
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.

RESERVE OXYGEN SYSTEM

As a precaution, your Sunrise Medical/DeVilbiss provider may supply you with a reserve oxy-
gen 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 Sunrise Medical/DeVilbiss provider.
