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
ame.
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 briey and audible signal will briey 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 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 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 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 briey. After a few
seconds, only the Power and Normal Oxygen lights will remain lit.
The OSD lights on the front 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 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.
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.
CARING FOR YOUR DEVILBISS OXYGEN CONCENTRATOR
NOTE– Use no lubricants, oils or grease.
WARNING
Before attempting any cleaning procedures, turn the unit “Off.”
Cannula/Mask, Tubing, and Humidifier Bottle
Clean and replace the cannula/mask, tubing, and humidier bottle according to the manufacturer’s instructions.
Air Filter and Oxygen Outlet Connector
The air lter and connector should be cleaned at least once a week. To clean, follow these steps:
1. Remove the air lter, located on the back of the unit. Remove the oxygen outlet connector (if used).
2. Wash in a solution of warm water and dishwashing detergent (Figure 5).
3. Rinse thoroughly with warm tap water and towel dry. The lter should be completely dry before reinstalling.
CAUTION– To prevent product damage, do not attempt to operate the unit without the air lter or while the lter is still damp.
Exterior Cabinet
As needed, clean the concentrator exterior cabinet by using a damp cloth or sponge with a mild household cleaner and wipe it dry.
WARNING
To avoid electric shock, do not remove the concentrator cabinet. The cabinet should only be removed by a qualied DeVilbiss technician. Do not apply liquid
directly to the cabinet or utilize any petroleum-based solvents or cleaning agents.
Use of harsh chemicals (including alcohol) is not recommended. If bactericidal cleaning is required, a non-alcohol based product should be used to avoid
inadvertent damage.
