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
go to the doctor immediately.
16. When the user is a child or a person with limited mobility, the device needs to be used under the
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.
