WARNING:Users who require continuous oxygenation must plan for
alternate reserve sources of power and oxygen in the event of a
failure or loss of power and oxygen. This device is to be used as an
oxygen supplement and is NOT considered life-supporting or life-
sustaining!
WARNING: There is a risk of fire associated with oxygen enrichment
during oxygen therapy.
Do not use the oxygen concentrator or accessories near sparks or
open flames.
WARNING: To ensure receiving the therapeutic amount of oxygen
delivery according to your medical condition [insert model and brand]
must
- Be used only after one or more settings have been individually
determined or prescribed for you at your specific activity levels.
- Be used with the specific combination of parts and accessories that
are in line with the specification of the concentrator manufacturer and
that were used while your settings were determined.
WARNING: 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.
WARNING: Do not lubricate fittings, connections, tubing, or other
accessories of the oxygen concentrator to avoid the risk of fire and
burns.
WARNING: Use only spare parts recommended by the manufacturer
to ensure proper function and to avoid the risk of fire and burns.
WARNING: Use of this device at an altitude above [insert maximum
RATED altitude] or outside a temperature of [insert RATED
temperature range] or a relative humidity above [insert maximum
RATED relative humidity] is expected to adversely affect the flowrate

and the percentage of oxygen and consequently the quality of the
therapy.
WARNING: 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.
WARNING: If you feel discomfort or are experiencing a medical
emergency while undergoing oxygen therapy, seek medical
assistance immediately to avoid harm.
WARNING: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.
WARNING:Open flames during oxygen therapy are dangerous and is
likely to result in fire or death. Do not allow open flames within 2 m of
the oxygen concentrator or any oxygen carrying accessories.

DO NOT modify this equipment without authorization of the
manufacturer.
Read the following information before operating this product.
1.2 Before Installation
The concentrator should always be kept in the upright position to
prevent damage during transport.
If the electrical power source becomes unstable, discontinue use
and find an alternate source.
Only use stable and safe electrical power sources.
The oxygen concentrator cabinet should ONLY be opened by an
authorized equipment provider.
1.3 Placement
● You may select a room in your house where using your oxygen
concentrator would be most convenient. Your concentrator can be
easily roll from room to room on its casters.
Do not place the oxygen concentrator in surroundings where its
airflow is obstructed.
Be certain to place the oxygen concentrator so that all sides are at
least 10 centimeters (4 inches) away from walls, draperies, furniture,
or similar surfaces. Avoid deep pile carpets and heaters, radiators or
hot air registers.
Do not place the unit in a confined area.
The oxygen concentrator MUST be kept away from heat, fire and
excessive water sources and conditions.
The oxygen concentrator should be located so as to avoid

1、SAFETY NOTES
7
pollutants or fumes.
Do Not place items on top of the concentrator.
NEVER block the air openings of the unit or place it on a soft
surface, such as a bed or couch, where the concentrator may tip or
fall. Keep the openings free from lint, hair and
the like.
1.4 Fire Warning and Explosion
Keep the concentrator away from flammable and explosive areas.
Users MUST NOT SMOKE while using this device. Keep all
matches, lighted cigarettes or other sources of ignition out of the
room in which this product is located. NO SMOKING signs should be
prominently displayed. Textiles and other materials that normally
would not burn are easily ignited and burn with great intensity in
oxygen enriched air. Failure to observe this warning can result in
severe fire, property damage and cause physical injury or DEATH.
The use of oxygen therapy requires that special care be taken
to reduce the risk of fire. Any materials that will burn in air, and some
that will not, are easily ignited and burn rapidly in high concentrations
of oxygen. For safety concerns, it is necessary that all sources of
ignition be kept away from the product and preferably out of the room
in which it is being used.
A spontaneous and violent ignition may occur if oil, grease or
greasy substances come in contact with oxygen under pressure.
These substances MUST be kept away from the oxygen concentrator,
tubing and connections, and all other oxygen equipment.
DO NOT use any lubricants unless recommended by manufacturer.

1.5 Maintenance
The oxygen concentrator was specifically designed to minimize
routine preventive maintenance at intervals of once per year. Only
professionals of the health care field or persons fully conversant with
this process such as authorized or factory trained personnel should
perform preventive maintenance or performance adjustments on the
oxygen concentrator.
DO NOT service or maintain while patient in use.
● For optimum performance, manufacturer recommends that the
concentrator be on and running for a minimum of 30 minutes at a time.
Shorter periods of operation may reduce maximum product life.
1.6 Radio Frequency Interference
Most electronic equipment is influenced by Radio Frequency
Interference (FRI). Always exercise CAUTION with regard to the use
of portable communications equipment in the area around such
equipment.
Energy of Radio Frequency of this machine is just for device
operation use, so the Radio Frequency is very low, will not affect
the running of other electric equipment around regard to the use of
portable communications equipment in the area around such
equipment.

level in use. When the tube of oxygen exit of humidifier wrested or
jammed, the pressure in humidifier will ascend to 25±5kPa, the
safety valve of humidifier will open to release the pressure.
●Expected service life of humidifier bottle: 3 years.
Inspection of performance of humidifier：1. use the PVC soft tube to
connect the humidifier adapter and the oxygen outlet of the shell; 2.
turn on the oxygen concentrator, adjust the flux to about 5L/min, jam
the exit of humidifier, after about 5 seconds, the safety valve will open,
the gas will release, the valve will close, which indicate the gas
proofing of humidifier and safety valve in conforming.
4.2 PREPARE WORK
●Unscrew the cover of the humidifier, fill the purify water (or distil
water) into the humidifier bottle between the maximum and minimum
water level lines, and then screw the humidifier bottle. (If needed, add
other medicine into the water, please according to the doctor’s
suggestion.)
●Screw the humidifier bottle absorbing connector into the cover of the
humidifier, then insert the humidifier to the elastic belt on the left side of
the unit, and connect the other end of the cannula to the oxygen outlet.
●Plug in power supply：Ensure that the power switch is off; plug the
concentrator’s AC connector into power outlet.
4.3 Turning the Concentrator ON
●Press power switch to the“|”position. At that time green, yellow
light all will be on which means the function of machine is normal.
After about 1 second, only green light on. After 4 seconds, the

display will show accumulation work time.
●To properly read the flowmeter, locate the prescribed flow rate
line on the flowmeter. Next, turn the flow knob until the ball rises to
the line. Now, center the ball on the L/min. line prescribed (Figure
3).
NOTE: Oxygenation times and the flow rate ranges are established
and prescribed by your physician.
