1. Press the humidifier bottle
unload button (Figure 3) and
remove the humidifier bottle.
2. Take out the humidifier bottle lid
and fill the humidifier bottle with
purified water or distilled water
of room temperature. The water
level can't exceed the maximum
marked water level line.
Note:
a) Please don’t put tap water into
the humidifier bottle to avoid
impurities clogging the
humidifier bottle.
b) If there is no water filled into
humidifier bottle, Oxygen
concentrator can also release
oxygen but the oxygen is very
dry and may affect comfort.
3. Buckle up the lid after adding water and put the humidifier bottle back to
main unit.
4. Connect the power cord. Plug one end of power cord into oxygen
concentrator (Figure 2) and the other end into electrical outlet.
5. Press the power switch to “一”, then the start key on the screen will be
lit. Click it to start up the oxygen concentrator, and the screen will be lit
and there are bubbles emitting in the humidifier bottle. After the green
“Normal” light is lit, the equipment calibration is completed and users can
start to operate the equipment. The whole process may take about 1
minute and the “Flow ±” button is not workable. The oxygen concentrator
should produce a “hiss–” sound in normal working conditions, which is a
normal ventilation sound.

“Timing ±”, “Nebulization” and “SOS” functions are normal to use.
2. Flow Control
After the device enters normal work state, Users short press of “Flow +” /
“Flow -” in the control panel or the telecontroller will make the oxygen flow
increase / reduce 1L/min, If long press the keys will make the flow continue to
increase or reduce at the speed of 0.1L/min.
3. Timing Function
Short press “Timing +” / “Timing -” in the control panel or the telecon-
troller to do timing operation. Short press the keys can do the timing at speed
of 20min/time. Long press the keys can do the timing at speed of the continu-
ing rate of 20min. The device will turn itself off after the timing time runs out.
4. Nebulization Function
This function needs to connect to the nebulizer mask. Users should
connect the nebulizer mask to “nebulization” outlet (as showed Figure 2).
Press the nebulization button on control panel or the telecontroller and the
nebulization indicator light will be lit, then users can do the nebulization. The
noise is becoming larger during the nebulization process, It is the normal
voice. After the nebulization, Press the nebulization button again to return
back to oxygen production mode.
Note: After using nebulization function, Data of timing time and elasped time
on the screen will become zero and the equipment takes 1 minute to do
recalibration.

5. SOS Function
When users had sudden diseases and can not call for help, they can
press on the “SOS” key in the control panel or the telecontroller for help, and
the device will continue to voice out “help me” to seek for help. To turn off the
SOS function, just click on any function key on the control panel to close the
SOS function.
6. Anion Function
Anion can improve alveolar ventilating function, enhance oxygen
absorption rate. This function is always on state.

After turning on the device, the inner lamps of humidifier bottle and the
top of device is turned on. Long press the “SOS” button can turn on/off the
inner lamp of the top of device.
The inner lamp of humidifier bottle can help users to see the water
volume and check if the oxygen flow is normal or not. So it is always lit and
users can not close it in process of normal work condition.
8. Radio Function
This Function need to operate by the telecontroller.
Note: This function may not be available due to different wave band in
different countries.
9. Power Off
Press the key in the control panel to turn off the device.
Note: The button functions on telecontroller are same with control panel of
main unit except the long button function. The remote control range
is around 6m, Please operate it facing the front side of equipment.
