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-" key is the same withthe "Timing +" key.

4. Negative ion key

The function of negative ion is synchronized with the system,and can work independently.In working condition or standby state,touch the "negative ionkey to close its function; and touch the key again to start the function.

5. Flow rate setting key

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

6.lnfrared remote control

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

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 purifed 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 flter cleaning

The white air flter 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.

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 humidifer 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 environ-ment.
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-termstorage

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 humidifer water tank.

Common Trouble-shooting

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 silicone tube and ABS rubber parts is normal and non-toxic by inspection. The odor will disappear as time goes by.
1	Odor in air.	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.
2	Water flows from the oxygen outlet.	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 oxygen outlet.
3	The machine lets "puff" sound every several seconds	It is the sound of nitrogen discharging which is normal and is a sign 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 power cord and contact professionals to repair it.

5	After startup, there is bubble in the water tank, but there 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.
6	After startup, the indicator light works, but the machine does not (the sound is irregular).	Compressor malfunction.	Disconnect the power cord and contact professionals to repair it.
6		The temperature is so high that the self-protection mode of the oil-free compressor is activated.	It is a normal case. When the temperature lowers down, the machine will restart automatically.
7		Separation valve malfunction.	Disconnect the power cord and contact professionals to repair it.
7		The inner connection 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.

Operating Principle

The air comes into the compressor after compressed by air inlet flter 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 fne 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 fne sieve tower and controlled fow size by fowmeter. Then the oxygen is humidifed by the humidifying water tank when it comes to it. Finally, the oxygen reached the user through oxygen supply tube.
