Installation steps:
1. Make sure the CO2 cylinder is empty.
2. Twist off the adapter from the origin CO2 cylinder. (Retain the pink gasket)
3. Attach the soda stream bottle adapter to the adapter. (Be sure to screw it very tightly so it will not leak)
4. Attach the assembled fittings to the machine and secure them in place.
5. Link the adapter to the hose and the hose to the large CO2 storage bottle.
