Preparation

Pull out the humidification bottle gently along the direction shown in the figure, pull out the rubber plug at the top and add cold the purified water of exceeding the maximum water leve (Figure 5)

Note: the water tank can be positive without adding water regular oxygen production

Close the water tank with rubber plug,and replace the humidified water tank with the machine
Connect the power supply, connect one end of the power line to the outlet hole of the oxygen generator, and the other end to the outlet with power output
Press the power switch to “I”, then enter the standby state. Press the “switch” key, then enter the normal operation state. When the oxygen generator is working, it makes a sound of “Chi ~” every few seconds, which is a normal breath sound.

Oxygen Intake Operation

Press the “flow” button in the control button area to adjust to the required flow rate. The oxygen outlet should have oxygen output..
Connect oxygen pipe nozzle to oxygen outlet of moisture bottle. Adjust nosal tube to make the inhaler comfortable, then allow to inhale oxygen.

Timing Function Operation

The generator has timing function. The user can set the time within 5 hours.

At the initial startup, the display screen displays “working time”, indicating that the timing shutdown function is not set and is in continuous operation until the switch is pressed to shut down.
Press the “timing +” key to change the “working time” to “timing”. Press the “timing +” key once to increase the display number by 10 minutes. Press the “timing -” key to decrease the display number by 10 minutes. If the timing key is not pressed, the timing will be fixed and decrease with the running time.
After the set time, the oxygen generator will automatically shut down. At this time, the display screen displays “timing — h — M”, press the on key to restart

Voice operation

Press the “voice” button in the control button area to turn voice on and off.

Shut down

If it is necessary to stop oxygen absorption temporarily during use, press the “switch” key on the control panel to stop and start oxygen supply.
After use, first press the “switch” key to stop oxygen production, then turn off the power switch, then unplug the power plug and cut off the power supply of the network.

Wireless Remote Control

When oxygen generator is in normal operation or standby mode, start, shut down or adjust the oxygen generator by means of wireless remote control.

Note: the remote control should be in front of the machine

How to use the oxygen absorber

Introduction to oxygen absorber

Nasal oxygen tube: can be hung on the ear, easy to operate, easy to use.

Usage method

Before oxygen absorption, connect the connector end of the oxygen pipeline to the oxygen port, and the other end of the oxygen pipeline to the nasal oxygen pipe joint. Rotate the oxygen inhaler to an appropriate Angle and wear it as shown in figure 6
Wearing method of nasal oxygen tube (see Fig. 6 and 7)
Oxygen head cleaning: wipe with medical alcohol.
Cleaning: generally once a week, it can be cleaned with a lighter detergent, and then washed with clean water. The water in the bottle should be dried before use.

How to use the atomizer ()

Add the liquid medicine into the atomizing cup, insert the atomizing mouthpiece into the atomizing cup mouth; unscrew the atomizing mouth joint anticlockwise; connect the atomizing mouth and the atomizing cup with an air catheter, the atomizing cup begins to produce fog, the mouth contains the atomizing mouthpiece, and start the atomizing treatment with the mouth breathing

Warning: before maintenance of the oxygen generator, first cut off the power supply. To avoid electric shock, do not disassemble the casing.

Clean the housing

Keep the housing clean: first power off, use wet and soft cloth immersed in sterilizing fluid to clean and prevent any liquid from going into the clearance of the housing.

Replace filter

The replacement of filter is very important to protect compressor and molecular sieve and prolong the service life of oxygen generator. Please replace it in time. If the concentrator has been used for 300 hours, the filter shall be replaced once.

Warning: do not operate the oxygen generator when the filter is not installed, which will damage the machine for a long time

Pull out the filter cover (see Figure 8)；
Pull out the filter and replace it with a new one (see Fig. 9).
Press the filter cover back in place

The actual replacement time of the filter shall be determined according to the actual use time and environmental impact. If the filter element is blackened, it shall be replaced immediately regardless of the use time.

Clean the humidification water tank

Water in the humidification water tank shall be replaced every day.
Clean the humidification water tank once a week, and wash it with clean water repeatedly to ensure oxygen sanitation. When cleaning the humidification water tank, pay attention to clean the rubber plug.

Note: if there is scale or peculiar smell in the water tank due to long time of cleaning or water change, soak it in white vinegar for more than half anhour, shake it vigorously, clean it and then rinse it with water.

Disassemble the humidification water tank

Pull out the humidification water tank along the direction shown in the figure (Figure 10)
Remove the rubber plug (Figure 11）

Wash oxygen pipe

Normally, oxygen pipe shall be washed three times a day. Nosal head of oxygen pipe shall be washed after each use. Immerse it in white vinegar for 5 minutes and then wash it with water or clean it with medical alcohol. It is suggested to replace oxygen pipe once every two months.

Note: keep the inside of oxygen pipe dry, without any water.

Replace fuse

First, cut off the power supply. The fuse holder is located at the bottom of the machine. Use a cross screwdriver to screw out the fuse holder cover anticlockwise, and then take it out for replacement. (Note: fuse model: T1.6AL250V, Φ5 * 20)

Common troubleshooting guide

Fault phenomenon	Possible causes	Elimination method

The oxygen generator has power supply, but the machine does not work and the display does not show| 1）Fuse of power supply is broken| 1）Replace fuse tube
2 ） Insufficient power at power outlet| 2）Do not use extension cords to move the concentrator to another power outlet or circuit
3）If the concentrator is still not working, contact the equipment supplier or manufacturer
The oxygen generator works, but there is little or no air output at the oxygen inlet| 1) Kinked or blocked oxygen pipeline| 1)Straighten out the pipeline
2）The rubber plug of the humidification bottle is not covered tightly or is missing| 2）Retighten
3)Blocked humidification water tank| 3）Clean the humidification water tank
4）Filter dirty| 4）Replace filter
5）Contact supplier or manufacturer if persistent
The oxygen generator has power supply, but the machine does not work, and the display shows “fault”| 1)Compressor overheating protection, shutdown| 1）Shut down and restart the machine after it cools down
2）If this condition persists, stop using the machine and contact the equipment supplier or manufacturer immediately

Note: if the failure of oxygen generator cannot be eliminated, please contact the supplier or manufacturer.
