PATIENT ALERT SYSTEM

The DeVilbiss Oxygen Concentrator patient alert system will
detect unit component failure.This system is comprised of both
visible and audible alarms which signal the patient if a malfunction
should occur.
The visible alarm located on the front panel (Figure 1) reads
"Service Required." The audible alarm system is internally
powered; no batteries are required.When the indicator lights
illuminate or the audible alarm sounds, other than during unit
start-up, a problem has occurred.
Non-OSD models:
• Power Failure (Blinking red "Service Required" light
and pulsing audible alarm)
• Low Flow (Continuous red "Service Required" light and
audible alarm)
OSD models:
• Power Failure (Blinking red "Service Required" light
and pulsing audible alarm)
• Low Flow (Below 0.5 lpm) (Continuous red "Service
Required" light and audible alarm)
• Below Normal Oxygen (84% to 75%, yellow "Low Oxygen"
light. 75% to 60%, yellow "Low Oxygen" light and beeping
audible alarm. Less than 60%, red "Service Required" light
and beeping audible alarm.) Refer to Specifications for spe-
cific alarm settings.
The visible and audible alarms will activate for approximately
15 minutes in a no power situation. If the unit is turned "On"
without power or power is removed later, no alarm will sound
for the first 10 seconds. After that time, the alarm will produce
an audible pulse every few seconds while the visible alarm
blinks. Power for this alarm is provided by a capacitor on the
PC board.
NOTE: If the concentrator has been unused for an extended
period, the unit must run several minutes before the power fail
alarm will activate.
The PC (printed circuit) board (Figure 5) is responsible for
controlling the system and alarms.
NOTE: A high pressure condition is indicated by the audible
(a "popping" sound) release of pressure from a pressure relief
valve located on the compressor head.

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:
• Wash the humidifier bottle in a solution of hot water and
dishwashing detergent.
• 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.
• 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 and Oxygen Outlet Connector
The air filter (Figure 3) and oxygen outlet connector should
be cleaned at least once a week by the patient.To clean, these
steps should be followed:
1. Remove the air filter located in the door on the back of the unit.
Remove the oxygen outlet connector (if used) from oxygen out-
let port (Figure 1).
2. Wash in a solution of warm water and dishwashing detergent.
3. Rinse thoroughly with warm tap water and towel dry.The fil-
ter should be completely dry before reinstalling.
WARNING: Do not attempt to operate the unit with-
out 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.
CAUTION: Operation of the DeVilbiss Oxygen
Concentrator in extreme environments or without the
air filter will prematurely occlude the intake bacteria
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.
