Loosen the CO2 bottle sheath (Show as figure 15), insert a
4.
16gram CO2 cartridge in the sheath (Figure 16), and screw the
sheath tightly until you will hear a "Click"(Figure 17), which
indicates that the cartridge seal has been pierced and the CO2
gas can flow into the keg freely. Make us the bottle sheath is
fixed tightly to avoid the CO2 leakage. Then put CO2 bottle
sheath into the top cover.
