Before the charging process, please put the small cylinder in the refrigerator to cool down to ensure that the small cylinder can be filled with more carbon dioxide gas.
1. Confirm that the on/off valve A and release valve C are closed(90 degrees to the ball valve body), and turn the pin knob B of the small cylinder adapter to the top (counterclockwise).
2.( Put the gasket into the connector)Connect the connector (A end) to the large CO2 tank. (Tighten with a wrench. )
3. Connect the small cylinder to the cylinder adapter (B end adapter).
