OPERATING yOuR DEvILBISS OxyGEN cONcENTRATOR
DANGER
Oxygen causes rapid burning. Do not smoke while your oxygen concentrator is operating, or when you are near a person
utilizing oxygen therapy. Keep the oxygen concentrator at least 5 feet (1.6 m) from hot, sparking objects or naked sources of
flame.
1 . Press the power switch to the "On" position . When the unit is turned "On," all four lights (Power, Service Required, Low Oxygen,
and Normal Oxygen) on the front panel will illuminate briefly and audible signal will briefly alarm. After a few seconds, only the
Power and Normal Oxygen lights will remain lit .
DANGER
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 6 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 6, 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 flow of oxygen – consult your physician.
NOTE– Your 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– 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 flow
higher than 5 may cause the oxygen purity level to drop.
NOTE– The low-flow alarm will activate if the flow 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 flow meter to your prescribed flow.
NOTE– Installation of 515LF-607 low output flow meter package will cause the low flow alarm to not work.
3 . Your DeVilbiss concentrator is now ready for use, properly position the cannula or mask (Figure 4) . 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 6 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 .

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 .
