Product Use

Use precautions

Attention:

1. During use, ensure unobstructed exhaust at the bottom of oxygen concentrator, otherwise it may cause internal overheating.
2. When the output oxygen is less than the maximum recommended flow, oxygen concentration reaches 90%. When the flow exceeds the maximum recommended flow, oxygen concentration will reduce with the increase of flow.
3. Oxygen concentrator will reach the specified performance after started for 10 minutes.
4. There will be intermittent exhaust sound (every 7-12 seconds around) during operation of oxygen concentrator, which is normal.
5. No oil, grease or other similar substances shall be used on or near oxygen concentrator, and no lubricant other than those recommended by the manufacturer shall be used.
6. During use, timely add water when water level of humidifier bottle is below the minimum level.
7. Oxygen concentrator shall not be started frequently, it shall be restarted after stopped for 5 minutes.
8. Molecular sieve will become aging due to use time and environment etc., causing unrecoverable decrease of oxygen concentration amount. In case of this phenomenon, please contact the dealer or manufacturer to replace the molecular sieve.
9. For long-term stopping of oxygen concentrator, be sure to unplug the power cord.

Operation Steps
