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 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、SAFETY NOTES

1.5 Maintenance
Oxygen concentrator shall be maintained once a year at least. Only
the professional healthcare person familiar with the operation of this
device (e.g. personnel trained or approved by manufacturer), can the
maintenance or debugging of 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.

1.7 To Reduce the Risk of Burns, Electrocution, Fire or Injury
to Persons.
Avoid using while bathing. If continuous usage is required by the
physician’s prescription: The concentrator must be located in another
room at least 2.5 meters (8.2 feet) from the bath.
DO NOT come in contact with the concentrator while wet.
DO NOT place or store product where it can drop into water or
other liquid.
DO NOT reach for product that has fallen into water. UNPLUG
IMMEDIATELY and call Qualified Service Personnel for examination
and repair.
A product should NEVER be left unattended when plugged in.
This device is to be used only in accordance with the prescription of
a physician and this User’s Manual. If at any time the patient or
attendant concludes that the patient is receiving an insufficient amount
of oxygen, contact the provider and/or physician immediately. No
adjustments should be made to the flow rate unless prescribed by a
physician.
Close supervision is necessary when this product is used near
children or physically-challenged individuals.
Use this product for only intended use as described in this manual.
DO NOT use parts, accessories or adapters other than those
authorized by manufacturer. Use of certain humidifiers and
administration accessories not specified for use with this oxygen

concentrator may impair the performance.
If replacement parts used for the periodic servicing by an approved
technician do not comply with the manufacturer’s specifications, the
manufacturer is not responsible in the event of an accident.
DO NOT connect the concentrator in parallel or series with other
oxygen concentrators or oxygen therapy devices.
In certain circumstances oxygen therapy can be hazardous.
Manufacturer recommends that you seek medical advice before using
this product.
Avoid creation of any spark near medical oxygen equipment. This
includes sparks from static electricity created by any type of friction.
If the concentrator has a damaged cord or plug, if it is not working
properly, if it has been dropped or damaged, call Qualified Service
Personnel for examination and repair.
Keep the cord away from HEATED or HOT surface.

Figure 2: Humidifier Features
DO NOT add water over the maximum water level. Pure water shall be added
in humidifier to between maximum and minimum water level in use.
●Power switch——I indicate the power is on, O indicate the power is off.
When the switch locates on “ON”, if the power cutting occurs, the oxygen
concentrator will not run, there will be alarm noise.
●The oxygen will be obtained by passing humidifier. Pure water shall be added
in humidifier to between maximum and minimum water 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.
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、INSTALLATION AND OPERATION
19
4.3 Turning the Concentrator ON
Press power switch to the“|”position. The display will show
“HELLO”. At that time green, yellow, red 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.
Figure 3
CAUTION: If the flow rate on the flowmeter ever falls below
0.5L/min, check tubing or accessories for blocked or kinked tubing
or a defective humidifier bottle.

4.4 Alarm Signal
Initial startup of the concentrator
NOTE: Concentrator may be used during the initial start warm-up
time (approximately 30 minutes) while waiting for the O2
concentration to reach maximum.
When the unit is turned on, the green light will come on (O2
concentration greater than 82%±3%). After 5 minutes, the
oxygen sensor will be operating normally and will control the
indicator lights depending on oxygen concentration values. The
explanations of the indicator light functions are as follows.
