⚫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.

4
➢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.
➢Do not block the air inlet and outlet of the oxygen concentrator.
➢Do not disassemble the oxygen concentrator to prevent electric shock. If the oxygen concentrator is in fault, please
contact a dealer authorized by CARER timely.
➢When the oxygen concentrator is not in use, please unplug the oxygen concentrator from the power socket.
⚫Main Structure
The medical oxygen concentrator is composed of a mainframe, a flow controller, a humidification bottle and an oxygen
concentration status indicator.

⚫Installation of Oxygen Concentrator
1. Place the oxygen concentrator in the place where you stay for the longest time and near the socket. It can
be the living room, studyroom, bedroom, etc. But please do not place or store it in the kitchen or bathroom.
DANGER: Do not place the oxygen concentrator at a place if there are objects with high
temperature, sparks and open flames within 1.6 m.
NOTE: Do not connect it to a wall outlet controlled by a switch.Do not have other appliances
plugged into the same wall outlet.

2. Place the oxygen concentrator at least 50 cm away from the wall, fabric or other objects. This will ensure
that a proper flow of air enters and exits the oxygen concentrator. The oxygen concentrator should be
kept away from pollutants, smoke, and humidity.
3. It is recommended to use a nasal oxygen tube longer than 2 meters.
⚫Preparation before Operating the Oxygen Concentrator
1. Please check whether the air filter cotton (in the air filter cover of the oxygen concentrator) is clean before
using the oxygen concentrator every time. Please clean the air filter cotton every week when the oxygen
concentrator runs. It is recommended to shorten the cleaning time appropriately if the environment is
poor or there is too much dust-haze. How to properly clean the air filter cotton is discussed on Page 12
of this Manual.
2. Please install the oxygen concentrator accessories following the steps below.
1). Connection of humidification bottles:
Install the oxygen humidification bottle as follows:
a) Add purified water (or distilled water) to the upper and lower limits of the humidification bottle (Fig.
3), and tighten the bottle cap.
b) Put the humidifier on the humidifier connection base of this product (Fig. 4). Please make sure that
it is firmly installed.
Fig. 3 Fig. 4
NOTE: The amount of water added to the humidification bottle should be between the maximum
and minimum water level marks.
Note: If you need to replace the humidification bottle, please contact a distributor authorized by
CARER to replace it with a SHP-01 humidification bottle.
2). Nasal oxygen tube connection:
Connect the nasal oxygen tube to the oxygen outlet (Fig. 5).

Fig. 5
Note: 5-7 mm tubaeform interface is adopted for the nasal oxygen tube and nebulizing device.
It is recommended to use a nasal oxygen tube and nebulizing device with a medical device
registration certificate.
3. Take out the power cord completely from the strap, make sure that the "power switch" is off (Fig. 6), and
then insert the plug into the wall outlet (Fig. 7).
Fig. 6 Fig. 7
WARNING: Improper power cords and plugs may cause burns, fire, or other electric shock hazards.
Do not use an oxygen concentrator with a damaged power cord.
⚫Operation Instructions
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 the oxygen concentrator if there is any object with high temperature, sparks and open
flames within 1.6 m.
1. Turn the "power switch" to the On (┃) position (Fig. 8), and then the power indicator will light up; after
pressing the "On / Off" button on the panel (Fig. 9) once more, the oxygen concentrator will start and the
normal operation indicator will light up.
