1. Fill your carbonating bottle with fresh cold tap or filtered water just to the "Fill Line" indicator.
2. Make sure you insert the carbonating bottle correctly (until you hear a click) there will be a small gap between the bottom of the carbonating bottle and the base of the sparkling water maker.
3. Press the carbonating button. Firm short bursts (approx. 2 sec) work best. Do not press more than 5 times.
4. If you'd like flavored sparkling water, add Sparkling Drink Mix to the bottle only after carbonating.
