Ⅱ. SPECIAL WARNING
01
1. This equipment is to be used as an oxygen supplement and is not intended to be life supporting or
life sustaining. In order to prevent power failure or possible failures of the oxygen concentrator, those
in urgent need of oxygen and critically ill patients must be equipped with other oxygen supply
devices (such as: oxygen cylinders, oxygen bags, etc.) as backup.
2. Seek medical advice before using this device.
3. It is mainly designed for general household use. It is not suitable to use in public places and health
care places.
Ⅰ. INTENDED USE
Oxygen inhalation in the general home and relief of respiratory disease.
Oxygen in the air is concentrated to support the respiration of patients living at home with respiratory
problems, mainly chronic obstructive pulmonary disease, etc.
Ⅲ. INSTRUCTIONS TO USE
1. The device and its components need to be carefully maintained to ensure the product life.
Therefore, the device must be carefully maintained based on the prescribed maintenance period,
especially in harsh working conditions.
2. If there is a quality problem, the customer shall not disassemble and repair it privately. If abnormal
phenomena such as the alarm is found, please contact the customer support for consultation (see
the back cover).
Ⅳ. SAFETY INSTRUCTIONS
1. Open flames or smoking during oxygen therapy are dangerous and may result in fire, facial burns, or
death. Do not allow smoking or open flames within 2m of the device or any oxygen carrying accesso-
ries, such as an attached cannula.
2. Do not use oil, grease or petroleum-based products on or near the device as the use of such products
may damage the electronic components of the device.
3. For proper operation, the device requires unobstructed ventilation.The device should be located as
to avoid pollutants or flames.
4. Do not plug or unplug the power cord when there is water on your hand. Otherwise it may cause
electric shock.
5. Do not use alcohol, solvents, polishes or any oily substances on the device. Otherwise, the output
oxygen may be contaminated, causing injury or physical discomfort.
6. When placing the oxygen concentrator, please keep a distance of 16cm from walls, curtains or other
objects, otherwise it may affect the air exchange of the air exhaustion of oxygen concentrator.
7. The device should not be used adjacent to or stacked with other equipment because it could result in
improper operation .
8. Do not use the oxygen concentrator if either the plug or power cord is damaged . Do not use
extension cords or electrical adapters.
9. Do not attempt to clean the concentrator while it is plugged into an electrical outlet.
10. The oxygen concentrator regularly emits a "ta..pu" exhaust sound when the oxygen concentrator
is operating (about 7 seconds).
11. The manufacturer recommends that the oxygen concentrator runs for no less than 30 minutes
each time when turned on. Do not turn on and off the oxygen concentrator frequently. It is suggested
to turn on/ turn off after 3 to 5 minutes each time, to avoid affecting the life of the compressor.
12. The use of accessories or service equipment not specified for use with the device may impair its
performance.
13. Please do not adjust the flow rate above 5L/min, otherwise the oxygen purity may not reach more
than 90%.
14. When the oxygen purity is abnormal, the user should contact the customer support for consulta-
tion (see the back cover).
15. If you begin to feel ill or are experiencing discomfort while using the oxygen concentrator, please

supervision of the custodian.
17. If you have plan not to use the oxygen concentrator for several days, please clean and dry the
humidification bottle for storage.
18. Molecular sieve is a consumable, it will absorb moisture from the air during use and storage, and
its performance will decay, resulting in a decrease in oxygen purity. Before the first use, if the oxygen
purity is lower than 90%, please contact the customer support for consultation (see the back cover).
19. Do not leave the nasal oxygen cannula on bed covering or chair cushion, if the oxygen concentra-
tor is turned on but not in use, the oxygen will make the materials flammable. Turn the device off
when it is not in use.
