1. Fill the bottle with fresh cold water (straight from the fridge is best!) to the fill line. Remember not to overfill!
2. Insert the bottle into the sparkling water maker in two movements: first press up and then push the bottle away from you until you feel the latch catch the bottle. Hint: there should be a space between the bottom of the sparkling water maker and the bottle when properly inserted.
3. Once the bottle is securely in place, press the carbonating button to carbonate your water.
