MAINTENANCE
PERIODIC HOMECARE PROVIDER PREVENTATIVE MAINTENANCE
Every DeVilbiss Oxygen Concentrator is tested at the factory. To assure continued trouble-free performance, the following preventative maintenance
should be performed by the homecare provider during periodic oxygen patient visits. Failure to properly maintain the unit will void the warranty.
1. Check the oxygen concentration with an oxygen analyzer (part #O2ANA)—every two years.
a. Calibrate the oxygen analyzer prior to checking the oxygen concentration. The analyzer should be properly calibrated using the
manufacturer’s recommended procedure.
NOTE–Changesintemperature,altitude,orhumiditymayaffecttheanalyzer’soxygenconcentrationreading.Theanalyzershouldbe
calibrated in similar conditions to the location of the concentrator.
b. Set the flow meter to 5 LPM. The concentrator must operate for a minimum of 20 minutes before checking the oxygen concentration.
c. Connect the analyzer to the unit’s oxygen outlet port and wait until the display stabilizes.
d. Record the reading.
2. Check the audible alert and indicator lights every two years. When the power switch is turned “On,” listen for the audible alert and check to see if
the front panel indicator lights are operating.
3. Inspect intake filter (part #MC44D-605) every 2 years or 8.760 hours. Replace as necessary.
a. Open the filter door and replace filter as required.
4. Inspect the final bacteria filter (part #PV5LD-651) every 3 years or 17.500 hours. Replace as necessary or in conjunction with compressor service.
a. Unplug the unit, remove the cabinet, and loosen the bib.
b. Remove the hose from each end of the filter and discard the filter.
c. Install the new final bacteria filter with the “IN” fitting toward the flow meter.
d. Tighten the bib and replace the cabinet.
5. Inspect the compressor filter (part #525D-622) every 5 years. Replace as necessary or in conjunction with compressor service.
