Operating 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 separating 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.

Safety precautions

In case of power outage and malfunction of the oxygen concentrator, an alternate source of supplemental oxygen (such as oxygen cylinder or oxygen bag)should be prepared for the user in urgent need of oxygen.The machine is not intended as medical device and is not to be used for life support or life extension.

 

Pre-installation

Upside down operation is 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.

 

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.

There should not be any obstruction around the air outlet on the back and bottom of the machine,in case of air inlet and air outlet blocked,which could lead to high temperature that will result in machines stoppage and decreasing of oxygen concentration.

 

Using

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.Do not switch on & off frequently. You can restart it after you have switched it off for 3-5 minutes considering its service life.Avoid oil or grease-like material for any part of the machine.So as not to pollute the oxygen machine and cause fire.

 

Product feature

The scope of product application: The product is designed in accordance with standard of Home personal usage appliance,Health function: improved oxygen absorption can improve the condition of the body to achieve the purpose of oxygen health care.Applicable to the elders, poor physique,pregnant women,students,and athletes restore physical function.

 

Function Feature

Intelligent control: LED display screen, easy use and

operations operate for timing function.Overheat protection: the pure oil-free air compressor with overheat protector, will stop working automatically when the compressor's working temperature is too high to protect the compressor and the whole part of the product.

 

Operating principle

This product uses AC220V/110V as power source, air as raw material and adopts the pure oil-free air compressor and qualified molecular sieve imported with original packaging,so as to generate high purity oxygen by PSA at normal temperate and supply oxygen.

Preparation Work

Filling water in humidification water tank:Grip the top handle of the humidification water tank by hand, pull out the water tank after pressing.

 

Open silica gel plug at top and fill pure water to the highest water level line.(Cool boiled water, distilled water and so on)*Do not exceed water level line.

 

Make sure to cover the rubber plug before using, align the positioning groove at the bottom of water tank and then the outlet,put the humidification water tank back to the main body.

 

Connect oxygen tube:Connect one end of "Oxygen tube" with "oxygen outlet mouth", and connect the other end with oxygen inhaler.

Care and Maintenance

1. 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 disinf-tant, Do not let the liquid penetrate into the machine.

 

2. Cleaning water tank

To keep the water tank clean,the water used should be purified 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.

 

 

3. Air filter cleaning

The white air filter at the back of the machine can reduce noise,isolate dust and purify the air. lt should be clean. lt 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.

* The air filter should be replaced every 2-4 months, depending on the usage environment.

 

4. Oxygen tube and oxygen inhaler cleaning

In general condition,it should be cleaned every three days. The snorting part of nasal cannula should be cleaned after each use. You can soak it with 5% potassium permanganate solution for 5 minutes,then rinse with clean water, or wipe it with alcohol. Change anew oxygen tube every year.

 

5. Long-term storage operations

Before you long-term storage the oxygen concentrator, please do as follows:

 

1. Bring down the humidifier water tank, pull out the water,dry it and position it back.

2.Disconnect the power cord and put away the power cord.3. Do not place please the machine in damp, dusting environment.Avoid direct sunlight and pollution. Preserve the oxygen tube and oxygen inhaler at room temperature. Do not twist the airway tube. Keep out of the reach of the children.

 

 

Do as follows before restart the machine after long-term storage period:

1. Make sure the power cord is undamaged.
2. Clean the oxygen tube and oxygen inhaler. Check whetherthe tube is blocked or twisted. Please straighten out.
3. Clean the humidifier water tank.
