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 nasal 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 — min”, 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. -

10. 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
1. 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
2. Wearing method of nasal oxygen tube (see Fig. 6 and 7)
3.0xygen head cleaning: wipe with medical alcohol.
4.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 (JY-105W)
» 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
Maintenance and Service
Warning: before maintenance of the oxygen generator, first cut off the
power supply. To avoid electric shock, do not disassemble the casing.
I. 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.
Il. 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.
ll. 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.
Disassemble the humidification water tank
When washing, pay attention to core tube and aerator at the bottom to keep oxygen smooth.
IV. 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:220V~:T1.6AL250V/ 110V~:T2.5AL250V, ®5 * 20 )
