Operation principle

 

Working Principle

Air enters the compressor after filtered by the air inlet filter and is compressed into molecular sieve tower for separation of oxygen gas and nitrogen gas. Then, oxygen gas passes through the molecular sieve tower and enters the fine sieve tower smoothly, while nitrogen gas is discharged into the atmosphere through the separating valve after adsorbed by the molecular sieve. After the concentration of oxygen gas is further increased in the fine sieve tower, the flow rate is controlled by the flow control valve, and then oxygen gas is wet through the humidification water tank and finally flows through the oxygen delivery pipe for supplementary oxygen inhalation by users.

 

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)voltage, 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 machine 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.

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 Max water Level

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.

 

Inhale Oxygen Operation

LED screen display instruction

1,Sleep function: The machine engage in sleep mode automatically after running for 3 minutes, the screen Lights dimmed to power saving.

2,Cooling fan indicator

3,Timing setting indicator

4,Generating oxygen indicator

5,Cumulative time indicator

1,Electricity

When the oxygen machine is power on, open the power switch on the shell, the buzzer sounds for a long time, then LED screen light.

2,Power on

Press the key 11 generate oxygen", the machine will start, open the cooling fan, timing setting function, generate oxygen function, Cumulative time function and brand Logo Light synchronously, there is LED display light and blue Light in water tank.

3,Timing +

Lightly touch the "Timing+" key, the timing is set to be 15 minutes. The timing setting is one-way circulation setting. The highest value is 180 minutes; 3 seconds after you have done the timing operation, the timer will start into a countdown process. The operation of the "Timing 一11 key is the same with the "Timing +" key.

4,Flow rate setting key

Through regulating vaLve knob to control the oxygen flow and concentration, the greater the flow, the smaller the oxygen concentration.

5,Infrared remote control

The remote control key function is the same with control panel key function.

 

Remote Control Instructions

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. It should be clean. 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.

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 a new 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 plase 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 whether the tube is blocked or twisted. Please straighten out.

3, Clean the humidifier water tank.
