Reserve Oxygen System; Provider's Notes - DeVilbiss Healthcare 515A Série Guide D'instructions

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–On later models of the 515 concentrators equipped with an OSD, the low-flow alarm may be activated if the flow meter ball is set
below 1 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 4). Allow 20 minutes for oxygen
concentrator to reach stated performance.

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.

The air filter and connector should be cleaned at least once a week. To clean, follow these steps:
1. Remove the air filter, 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 filter should be completely dry before reinstalling.

To avoid electric shock, do not remove the concentrator cabinet. The cabinet should only be removed by a qualified 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.

PROvIDER'S NOtES

In case of a change of patient, the device must be reconditioned to protect the user. Reconditioning must only be carried out by the manufacturer or service provider.
DeVilbiss Healthcare recommends the following as minimum between-patient maintenance. If the unit is due for periodic provider maintenance, those items should be
completed in addition to the list below.
1. Discard oxygen tubing, cannula/mask, oxygen outlet connector, and humidifier bottle.
2. Replace the cabinet air filter.
3. Clean the concentrator cabinet.
4. Inspect all plugs, cords, and components. Replace any damaged or worn components.
5. Check oxygen concentration. If the unit falls within specification, the extended life intake bacteria filter does not need to be replaced between patients. If the concentration
is not within specification, refer to troubleshooting.
6. If the device has been exposed to contagious pathogens, it should be discarded.
