⚫Overview
This Manual helps you to get familiar with how to use the oxygen concentrator. Please make sure that you
have read and understood this User’s Manual before using the oxygen concentrator. Important safety and
maintenance information is indicated in the instructions. Please pay special attention to all safety information.
If your oxygen concentrator is in fault, please contact a dealer authorized by CARER.
Danger: Oxygen can aid combustion.Do not smoke when the oxygen concentrator is turned on or
near someone who is working on it.
Do not use if there is any object with high temperature, sparks and open flames within 1.6 m.
⚫Reason for a Physician to Choose Oxygen Therapy
Nowadays, many people suffer from heart, lung and other respiratory diseases. To sustain certain organs
moving, your body needs a steady supply of oxygen. Your physician may ask you to supplement oxygen
because you cannot get enough oxygen from the indoor air. Supplementing oxygen can increase the total
amount of intaking oxygen in your body.
⚫Scope of Application
It is designed for oxygen therapy and nebulizing for patients with hypoxia at medical institutions and families.
⚫Principle for Oxygen Concentrating
This machine is driven by ~220 V power. By using air as the raw material and a high-quality molecular sieve, it produces
high-purity oxygen conforming to medical oxygen standard by pressure swing adsorption (PSA method) at normal
temperatures.
⚫Contraindications, Precautions, Warnings, and Instructions
Contraindications
➢This oxygen concentrator is not intended to sustain or prolong life.
WARNING
➢Do not unplug the oxygen concentrator when the power switch is not turned off.
➢Do not use the oxygen concentrator while bathing.
➢Do not place or store the oxygen concentrator next to a bathtub or sink.

➢Do not touch the oxygen concentrator after it falls into water or liquid, and immediately unplug the power. Do
not use the oxygen concentrator again after it falls into water or liquid, and notify a dealer authorized by CARER.
➢Do not place or store the oxygen concentrator in a kitchen or bathroom.
➢The oxygen concentrator should be placed away from pollution and smoke.
➢The air inlet of the oxygen concentrator should be located in a well-ventilated place.
➢It takes 5 minutes for the oxygen concentrator to start to reach the specified performance.
➢The oxygen concentrator should not be lubricated with oil, grease or other lubricants.
➢The performance of oxygen concentrator may be affected if any non-specified wetting bottles or drug
administration accessories are used.
NOTES:
➢It is recommended to assign a person to maintain the oxygen concentrator when using it.
