DANGER
Oxygen makes it easier for a re to start and spread. Do not leave the nasal cannula or mask on bed coverings or chair cushions if the oxygen concentrator is
turned ON but not in use, the oxygen will make the materials ammable. Turn the oxygen concentrator OFF when not in use to prevent oxygen enrichment.
NOTE – If the audible signal alarms but the unit is not operating, there is no power to the unit. Refer to the Troubleshooting chart on page 10, 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 Troubleshooting chart on page 10, and contact your
DeVilbiss provider if necessary.
2. Check the ow meter to make sure that the ow meter ball is centered on the line next to the prescribed number of your ow 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 cannot 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 may activate if the ow meter ball is set at or below 0.2 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.
3. Your DeVilbiss concentrator is now ready for use, properly position the cannula with the nasal prongs facing upward, insert the prongs
into nose. Wrap the cannula tubing over the ears and position in front of body (Figure 4). Allow 15 minutes for the 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.
The OSD lights on the top panel are dened 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, the yellow Low Oxygen light will illuminate, and an intermittent audible signal
will sound.
Refer to the Troubleshooting section in this guide on page 10, and switch to your reserve oxygen system. Do not attempt any other maintenance. Contact your DeVilbiss
provider immediately.
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. Please contact your oxygen provider if you have questions
regarding a reserve oxygen system.
