Pre-Installation
● Upside down operation prohibited.
● If the power supply has unstable voltage, or is beyond
AC220±22(110±10)volt, please connect the voltage regulator before using the machine.
● Please use standard socket with safety qualification and terminal board with electrical safety certification.
● Don’t open the case non professionals.
Laying Place
● The machine should be located in a well-ventilated space and avoid direct sunlight. The distance between the machine and the wall or other objects should be no less than 10cm.
● Do not put other things or liquid vessel on the machine.
● Stacking sundries is prohibited on the back and bottom vent of the machine, to prevent shutdown or decrease in oxygen concentration due to high temperature cause by blocked exhaust.
Using
● WARNING: Oxygen is a combustion-supporting gas, so do not smoke and keep away from combustion source while using the machine for fear of fire accident.

Oxygen Key
Press “oxygen key”, display is fully lit ,and machine is in oxygen and negative ion working condition,while the water tank light show blue. At same time, the screen displays preset time and accumulated time. Under working state, press the "oxygen key" to enter the standby state, and the fan will be turned off after a delay of 3 minutes.
Flow Regulation
Adjust the flow rate by pressing “flow regulation key”. Customer can control the oxygen flow rate according to their need. There are 1-7 stall points, it’s corresponding to 1-7L / min flow, oxygen flow increases and oxygen concentration decreases.Switch on in power off condition, the default flow value is 1L ,restart on standby. The value of the flow file will
retain the setting of the flow file when the device is turned off.
Timing Plus, timing minus key
Press“timing +” key to increase the timing each 15 minutes by one-way cycle setting, maximum setting is 180 minutes. After 3 seconds of inactivi-ty, the timing will start to count down until the timing automatically shuts down.When press "timing -" key, the time will be setting decreased as each 15 minutes from total 180 minutes.
Note: When operate functional key, it will be different at the statue of display“ 000”
1.In the highlighted state, press functional key will directly reflect operat-ing result.
2.In the power saving state, press functional key once to activate highlight mode , press it again , then it will reflect operating result.
Press any key each time , the buzzer sound once. It will be in power

Cleaning, Care and Maintenance
Cleaning housing unit
The surface of the housing should be cleaning at least once every month.
Disconnect the power cord before you clean it. Wipe it with a clean, mild, damp cloth soaked with disinfectant.Do not let the liquid penetrate into the machine.

Cleaning water tank
To keep the water tank clean, the water used should be pure water, distilled water or cold boiled water. we suggest to change water every day.
The water tank should be cleaned every week. First use mild detergent and shake the tank to wash. Then use clean water to rinse it,
After cleaned the water tank, please remember to put water tank plastic plug back to avoid leakage of oxygen from the water inlet, caused no oxygen output from oxygen outlet mouth when the machine is in normal working.
Air filter cleaning and replacement
The white air filter at the back of the machine can reduce noise, isolate dust and purify the air. It should be cleaned around every ten days.
First use mild detergent to wash, and then rinse it with clean water.
Pay special attention that it must be dry to be positioned back, or the function of the
molecular sieve could be damaged, which will lead to decreased oxygen concentration.
Cleaning oxygen Inhaler and atomizing components
Oxygen inhaler should be cleaned after use, and the nasal suction head on the nasal inhaler should be cleaned and disinfected after use.
Soaking the inhaler in the solution of 5% potassium ferric acid for 5 minutes, cleaning with water, or wiped with alcohol. Oxygen tube as consumable should be replaced regularly.
Fuse Replacement
After confirmed the power cord plug is out of power suppler outlet,using a slotted screwdriver to pry off the fuse holder cap, take out the defective glass fuse tube ,replace new one, put the cap back and tighten it.

Troubleshooting
| NO. | Phenomenon | Cause analysis | Solution |
| 1 | Odor in air. | In the initial stage of using, there is smell for the connection tube and other plastic parts. It is normal. |
The odor that comes from |
| The humidifier water tank hasn't been cleaned for a long time or the water hasn't been changed. | Clean the oxygen tube and humidifier water tank. |
||
| 2 | Water flows from the oxygen outlet. |
The water level of the humidifier water tank is beyond the highest water level, so the airflow pressed the bubble into the oxygen tube. |
Keep the water lower than the highest water level. |
| The machine has been used for a long time, so that the steam in the airflow gathers on the tube wall. | pour the water in water tank. And add water into the water tank when there is no water coming out from oxyhen outlet. |
||
| 3 | The machine lelse "puff" sound every several seconds | lt is the sound of nitrogen discharging which is normal and is asign of fine working. |
|
| 4 | After startup, the machine operates well, the flowmeter displays "0" or is too small |
The flowmeter is off or the value is too small | Turn up the oxygen flow. |
| The oxygen tube is twisted or blocked. | Straighten the oxygen tube. | ||
| The inner connection tube of the machine is disconnected or broken. |
Disconnect the powercord and contact professionals to repair it. |
||
| 5 | After startup, there is bubble in the water tank,butthere is no oxygen getting out from the oxygen outlet. |
The silica gel stopper of the humidifying water tank is not properly positioned. |
Remove the humidifying water tank to plug the silica gel stopper. |

| NO. | Phenomenon | Cause analysis | Solution |
| 6 | After startup, the in dicator light works, but the machine does not(the sound is irregular). |
Compressor malfunction | Disconnect the power cord and contact professionals to repair it. |
| The temperature is so high that the self protection mode of the oilfree compressor is activated. |
lt is a normal case.When the temperature lowers down, the machine will restart automati cally. |
||
| Separation valve mulfunction | Disconnect the power cord and contact professionals to repair it. |
||
| The inner conection tube of the machine is disconnected or broken. |
Disconnect the power cord and contact professionals to repair it. |
If it still does not work as you have followed the solutions listed above, do not disassemble the machine. Please consult the manufacturer for assistance.

Working Principle
The air comes into the compressor after compressed by air inlet filter unit, and then it enters into molecular sieve tower to separate the oxygen and nitrogen.
The oxygen successfully goes through the molecular sieve tower into the fine sieve tower.
In contrast, the nitrogen is absorbed by the molecular, then to be discharged into the atmosphere through the sepa-rating valve.
The oxygen concentration is enhanced in the fine sieve tower and controlled flow size by flowmeter.Then the oxygen is humidified by the humidifying water tank when it comes to it.
Finally , the oxygen reached the user through oxygen supply tube.
