service technicians and homecare providers with the proper maintenance,
service, safety, and repair procedures for the DeVilbiss Oxygen Concentrator.
Read and understand all the information contained in this service manual before
attempting to operate or perform any maintenance on the concentrator.
An oxygen concentrator is a device that delivers highly concentrated oxygen for
therapeutic applications.
Room air is a mixture of 78% nitrogen, 21% oxygen, 1% argon and other gases.
The concentrator draws in room air, separates the nitrogen from the oxygen, and
delivers concentrated oxygen to the patient through an oxygen port.

mixture with air or with oxygen or nitrous oxide.
This device contains electrical and/or electronic equipment. Follow local
governing ordinances and recycling plans regarding disposal of device
components.
Installation of 515LF-607 low output flow meter package will cause the low
flow alarm to not work.
Use only water-based lotions or salves that are oxygen-compatible before
and during oxygen therapy. Never use petroleum or oil-based lotions or
salves to avoid the risk of fire and burns.
Do not lubricate fittings, connections, tubing, or other accessories of the
oxygen concentrator to avoid the risk of fire and burns.
Use only spare parts recommended by the manufacturer to ensure proper
function and to avoid the risk of fire and burns.
Use of this device at an altitude above 4000 meters or above a
temperature of 95˚F (35˚C) or greater than 95% relative humidity may
affect the flow rate and the percentage of oxygen and consequently the
quality of the therapy. Refer to specifications for details regarding
parameters tested.
Oxygen makes it easier for a fire 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
flammable. Turn the oxygen concentrator off when not in use to prevent
oxygen enrichment.
If you feel discomfort or are experiencing a medical emergency while
undergoing oxygen therapy, seek medical assistance immediately to avoid
harm.
Geriatric, pediatric or any other patient unable to communicate discomfort
can require additional monitoring and/or a distributed alarm system to
convey the information about the discomfort and/or the medical urgency to
the responsible caregiver to avoid harm.
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.
Open flames during oxygen therapy are dangerous and are likely to result
in fire or death. Do not allow open flames within 2 m of the oxygen
concentrator or any oxygen carrying accessories."
