READ ALL INSTRUCTIONS BEFORE USING.
DANGER
1. NO SMOKING signs should be prominently displayed.
2. Oxygen causes rapid burning. Do not smoke while your oxygen concentrator is operating, or when you are near a person utilizing oxygen therapy.
3. Smoking during oxygen therapy is dangerous and is likely to result in facial burns or death. Do not allow smoking within the same room where the
oxygen concentrator or any oxygen carrying accessories are located.
• If you intend to smoke, you must always turn the oxygen concentrator off, remove the cannula and leave the room where either the cannula or
mask or the oxygen concentrator is located. If unable to leave the room, you must wait 10 minutes after you have turned off the oxygen
concentrator before smoking.
4. Oxygen makes it easier for a re to start and spread. Do not leave the nasal cannula or mask on bed coverings or chair cushions if the oxygen
concentrator is turned on but not in use. The oxygen will make the materials ammable. Turn the oxygen concentrator off when not in use to prevent
oxygen enrichment.
5. Keep the oxygen concentrator and cannula at least 2 m (6.5 feet) from hot, sparking objects or naked sources of ame.
6. Open ames during oxygen therapy are dangerous and are likely to result in re or death. Do not allow open ames within 2 m (6.5 feet) of the oxygen
concentrator or any oxygen carrying accessories.
7. Drive DeVilbiss oxygen concentrators are equipped with a re mitigating outlet tting that prevents propagation of re into the unit.

GENERAL INFORMATION
WARNING
Risk of injury or damage
1. When the device is operated at the extremes of the environmental operating specications (i.e., maximum temperatures and humidity), and in a single fault
condition, which is a single component or performance malfunction, such as a blocked exhaust vent, blocked air intake, or an internal cooling fan failure, the
temperature of the air coming out of the exhaust vents, located on the bottom left and bottom right sides of the unit can reach temperatures capable of causing a
burn injury (see stated temperature and contact time values in the model specic tables below).
2. Keep exposed body parts, such as hands and feet, a minimum of 62 inches (1.6 meters) away from the exhaust vents to avoid the risk of burns. Single fault
conditions may result in visual and audible alerts and alarms.
NOTE – Under normal and single fault conditions, the concentrator releases warm air out the bottom of the unit (exhaust vents) which may discolor
temperature sensitive ooring surfaces. The concentrator should not be used over ooring that is sensitive to heat staining. The Manufacturer is not responsible
for ooring that becomes discolored.
3. Operate the unit in a cool, dry area with good ventilation, located on a hard surface, avoid thick rugs or carpeting. NEVER block the air intake or exhaust vents.
Keep the unit a minimum of 12 inches (30.5 cm) away from any wall, draperies, or any other objects that might prevent the proper ow of air in and out of your
oxygen concentrator. Proper air ow is needed to prevent overheating of the oxygen concentrator. DO NOT place the concentrator near any heat source such as
hot air registers or heaters. Overheating of the oxygen concentrator may lead to low oxygen output and a risk of burns .
4. The oxygen concentrator should be located in a well-ventilated area. DO NOT operate the unit in a closed or conned space, such as a closet, bathroom, etc.
Avoid operating the device near smoke pollutants and fumes.
5. Under extreme environmental conditions and a single fault condition occurs, the following device surface temperatures may exceed 106 °F (41 °C). See Table 1

MAINTENANCE
PATIENT ALERT SYSTEM
The Drive DeVilbiss Oxygen Concentrator patient alert system will detect unit
component failure. This system is comprised of both visible and audible alerts
which signal the patient if a malfunction should occur.
DeVilbiss OSD®Operation
The OSD (Oxygen Sensing Device) is a device within your concentrator that
monitors the oxygen produced by your unit.
The OSD lights on the top panel are dened as follows:
Green Good Oxygen LED – acceptable oxygen level.
Yellow Low Oxygen LED – below the good oxygen level.
Red Critical Low Oxygen LED - below the critical oxygen level.
If the oxygen purity falls below the acceptable level, the green Good Oxygen
LED will shut off, the yellow Low Oxygen LED will illuminate, and an intermittent
audible signal will sound.
If the oxygen purity continues to fall into the critical low level, the Red Critical
Low Oxygen LED alerts with an audible alarm.
Refer to the Troubleshooting section in this guide. Do not attempt any other
maintenance. Contact your biomed technician immediately if the issue is not
resolved.
NOTE– Refer to the Alerts section below for specic alert settings.
NOTE– After power on, the electronics continuously monitor the oxygen
sensor. If a fault is detected, the appropriate LED(s) and/or audible alarms will
activate..
The rst 15 minutes, the unit will be in Start Up mode. The oxygen purity is
continuously monitored and the yellow Start Up Low Oxygen LED will be On.
The green Good Oxygen LED will turn on as soon as the therapeutic oxygen
levels are obtained. After 15 minutes stabilization time, if the O2is less than
82% the yellow Low O2LED will illuminate and a beeping audible alarm will
occur. If the oxygen level falls below 60% (after startup) then the red Critical
Low Oxygen LED will illuminate along with a beeping audible alarm.
Alerts:
There are several visible service alerts located on the control panel. The
audible alert system is internally powered; no batteries are required. If the
indicator lights illuminate or the audible alert sounds other than during start-up,
a problem has occurred. Detailed Alarm Information is found in Troubleshooting
section of this manual.
• Power Failure (Red Service Reqiured LED and pulsing audible alert.
• Low Flow (Red Low Flow LED and audible alert)
Below normal O2:
• The yellow Low Oxygen LED will illuminate with an audible alarm at
approximately <82%.
• The red Crtical Low Oxygen LED will illuminate with an audible alarm at
<60%.
The visible and audible alerts will activate for a minimum of two minutes in a no
power situation. If the unit is turned On without power or power is removed
later, the alert will sound within 10 seconds. After that time, the alert will
produce an audible pulse every few seconds while the LED ashes. Power for
this alert is provided by a capacitor on the PC board.
NOTE– If the concentrator has been unused for an extended period, the unit
must run for a minimum of 2 minutes before the power fail alert will activate. 10
minutes of run time is needed to fully charge the capacitors to run the power fail
alarm for the entire 120 second specication.
The PC (printed circuit) board is responsible for controlling the system and
alerts.
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.
NOTE– Settings below 1 LPM may activate the low ow alarm.
ALARM FUNCTION TESTING
The 1025 series is designed to activate alarms when certain conditions or
failures occur. The alarm functions may be tested following the procedures
below:
1. Overheating:
a. Remove the front and rear covers from the concentrator; then
disconnect the cooling fan from the printed circuit board.
b. Replace the front and rear covers.
c. Place the concentrator in a location that has an ambient temperature
of approximately 70° F. Then plug the unit into the appropriate mains
voltage and turn it on.
d. Allow the unit to operate until the Service Required Alarm activates,
