Routine Patient Maintenance
The oxygen patient should perform the following maintenance:
Oxygen Humidifier (reusable bottles only)
The patient should clean the humidifier bottle daily.The patient
should follow the instructions supplied by the manufacturer. If
no cleaning instructions were supplied, these steps should be
followed:
1.
Wash the humidifier bottle in a solution of hot water and
dishwashing detergent.
2.
Soak the humidifier in a solution of one part white vinegar
to three parts hot water for 30-45 minutes. This solution
acts as a germicidal agent.
3.
Rinse thoroughly with hot tap water and refill with distilled
water for use. Do not overfill.
Cannula/Mask and Tubing
The patient should clean and replace the cannula or mask and
tubing as instructed by the manufacturer.
Air Filter
The air filter should be cleaned at least once a week by the
patient. To clean the air filter, these steps should be followed:
1.
Remove the air filter, located on the back of the unit.
2.
Wash the air filter in a solution of warm water and
dishwashing detergent.
3.
Rinse thoroughly with warm tap water and towel dry. The
filter should be completely dry before reinstalling.
WARNING – Do not attempt to operate the unit
without the air filter or while the filter is still damp.
NOTE – The air filter should be monitored more closely in
environments with abnormal amounts of dust and lint.
NOTE – Operation of the DeVilbiss 5 Liter Oxygen
Concentrator in extreme environments or without the air fil-
ter will prematurely occlude the intake filter and cause a
decrease in the unit performance.
Exterior Cabinet
The patient should clean the concentrator exterior cabinet by
using a damp cloth or sponge with a mild household cleaner
and wiping it dry.
WARNING – Do not apply liquids directly to the
cabinet or utilize any petroleum-based solvents or
cleaning agents.

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 home-
care provider during periodic oxygen patient visits. Failure to
properly maintain the unit will void the warranty.
DeVilbiss 5 Liter Recommended Preventative
Maintenance (PM)
A.
Check oxygen concentration* with an oxygen analyzer
(part #O2ANA) - every 3 months for non-OSD models
and once every two years for OSD models.
To verify the oxygen concentration:
1.
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.
2.
The concentrator must operate for a minimum of 20
minutes before checking the oxygen concentration.
3.
Connect the analyzer to the unit's oxygen outlet port
and wait until the display stabilizes.
4.
Record the reading.
B.
Check the audible alarm and indicator lights - every two
years.When the power switch is turned "On," listen for
the audible alarm and check to see if the front panel
indicator lights are operating.
C. Inspect extended life intake bacteria filter if used (part
#MC44D-605) - once a year (under normal operating
conditions). Replace as required - not to exceed 8760
hours.
To change the filter (Figure 13):
1.
Open the filter door.
2.
Pull the extended life filter out from the rubber
grommet and discard.
3.
Place the current date and hours of operation on the
label of a new extended life filter.
4.
Insert the new extended life filter securely into the
grommet and close the filter door.
NOTE – If the DeVilbiss extended life intake bacteria filter is
not used, the following filters may be substituted. Note the dif-
ferent PM schedules.
• Round Felt Pre-Filter (part #444-503) - change
• Intake Bacteria Filter (part #444-504) - change
D.
Change final bacteria filter (part #PV5LD-651) - every two
years.
13
once a month OR Rectangular Felt Pre-Filter (part
#MC44D-722) - change every three months
