Below we also use text to describe the detailed operation steps:
1. Open the carton box, take the 1500ml machine as an example, and check all the contents: 1 machine, 2 single end cannular, 1 double end cannular, 1 drain pipe, 1 power cord, and 1 instruction manual.(like following picture)

2. Plug in the power, press the switch button on the back of the machine, the word "1" of the switch is "on", and the word "O" is "off".

3. Look at the front screen. At this time, the code of "E4 "will appear on the screen of the machine, which means lack of water. The machine cannot be started without water.

4. Unplug the H2 and O2 outlet plugs，when the machine is working, there should be no blockage at the outlet.

5. Open the cover, turn it counterclockwise, rotate 90 degrees, then lift it up,  (the cover will be tight, you need to twist hard to open it, the tight design is to prevent the gas running away from the cover).
