Smoking while using oxygen is the number one cause of fire injuries and related deaths.
You must follow these safety warnings:
Do not allow smoking, candles, or open flames in the same room with the device or within five feet of the
oxygen-carrying accessories.
Smoking while wearing an oxygen cannula may cause facial burns and possibly death.
Removing the cannula and putting it on bedding, sofas, or other cushion material will cause a fire when
exposed to a cigarette, heat source, or flame.
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 the oxygen concentrator off before smoking.

IMPORTANT SAFEGUARDS
Please read and understand this manual before operating your unit. Important
safeguards are indicated throughout this guide.
Pay special attention to all safety information. If you have any questions, contact
your provider.
WARNING: No modification of this equipment is permitted.
WARNING: For your safety, the oxygen concentrator must be used according to the prescription
determined by your provider. If you feel any discomfort or are experiencing a medical emergency while
undergoing oxygen therapy, seek medical assistance immediately to avoid harm.
WARNING: The device is not intended for life support. If the provider has determined that an interruption in the
supply of oxygen, for any reason, may have serious consequences to the user, an alternate source of oxygen
should be available for immediate use.
WARNING: It is the responsibility of the provider supplying the LM5BA to the patient to ensure that the device
is used in a safe and effective manner in keeping with the provider’s prescription for supplemental oxygen
use. While this manual is intended to support this goal, ultimate determination of the
patient’s safety resides with the patient’s provider.
WARNING: Availability of an alternate source of oxygen is required in case of power outage or mechanical
failure. Back-up oxygen should be available (oxygen cylinders, etc.).
WARNING: Do not use your oxygen concentrator in the presence of flammable gases. This can result in rapid
burning causing property damage, bodily injuries, or death. Do not use oil, grease, petroleum-based products
or other flammable products with the oxygen-carrying accessories or the Oxygen Concentrator. Only water
based, oxygen compatible lotions or salves should be used. Oxygen accelerates the combustion of
flammable substances.
WARNING: Only use a mild detergent applied with a damp (not wet) cloth or sponge to clean the cabinet,
control panel, and power cord and then wipe all surfaces dry. Do not allow any liquid to get inside the device.
Pay special attention to the oxygen outlet for the cannula connection to make sure it remains free of dust,
dirt, and particles.
WARNING: Do not operate unit in a restricted or confined space ( i.e., a small case or handbag) where
ventilation can be limited. This can cause the oxygen concentrator to overheat and impair performance.
WARNING: The oxygen concentrator should be located in an area away from smoke, pollutants or fumes

WARNING: The use of some oxygen administrating accessories is not specified for this oxygen concentrator
and may impair its performance. Recommended accessories are referenced in this manual.
WARNING: If the oxygen concentrator has been dropped, damaged, or exposed to water, please contact your
provider for inspection or possible repair of the device. Do not use the oxygen concentrator if it has a damaged
power cord or plug.
WARNING: Do not allow the air intake or air outlet vents to become blocked. Do not drop or insert any objects
into any openings on the device. This can cause the oxygen concentrator to overheat and impair performance.
WARNING: Do not overfill the optional humidifier. Fill the optional humidifier with water only to the level shown
by the manufacturer of the humidifier.
WARNING: If you feel any discomfort or are experiencing a medical emergency, seek medical assistance
immediately.
WARNING: Operating the unit outside of the operational temperature specifications can limit the
concentrator’s ability to meet oxygen concentration specification. Refer to the specification section of this
manual for temperature limits.
WARNING: The oxygen concentrator should not be used adjacent to or stacked with other equipment. If
adjacent or stacked use is unavoidable, the device should be observed to verify normal operation.
In the event of an alarm or you observe the oxygen concentrator is not working properly; consult the
troubleshooting section in this manual. If you cannot resolve the problem, consult your provider. To prevent
voiding the warranty, follow the manufacturer’s instructions.
WARNING: Do not attempt any maintenance other than the possible solutions listed within this manual. Do not
remove covers. Only your equipment provider or a qualified service technician should remove the covers or
service this device.
WARNING: Do not leave a nasal cannula on or under clothing, bed coverings or chair cushions. If the unit is
turned on but not in use, the oxygen will make the material flammable. Turn the oxygen concentrator off when
not in use.
Always disconnect AC power supply from the wall before disconnecting the AC power supply from the
oxygen concentrator. Always place oxygen supply tubing and power cords in a manner that prevents a trip
hazard.
