In order to use it correctly, please follow our instructions:

2. Screw the CGA320/W21.8 connection to a commercial CO2 gas cylinder.
3. Disconnect the quick connector of the black adapter, and then tighten the black adapter to for the cylinder( must turn the knob on the top of the black adapter to the highest position,the whole process does not need to turn the adapter knob down to open for the cylinder,If the adjusting rod press down 6mm wide valve pin, this will close the valve and CO2 cannot enter)
4. Connect the quick connector
5. For most big cylinders: turn the big cylinder or lie it down.(some host tank has not the dip/syphon tube inside.)
6. Carefully Open the valve of the gas bottle(The valve on for the Cylinder closes the flow if it is opened to much. This will happen if you open the big cylinder too much / too fast. The trick is to open the big cylinder very carefully. You will hear the air flow. So to fill it successfull)
