1. Please follow the instructions in the user manual to install the water bottle and the cylinder.
2. Press the button downwards firmly until you hear a sound from the valve. The carbonation time is 2-3 seconds each time. Do not continuously inflate for more than 5 seconds, as this will waste gas and cause excessive pressure in the bottle. After that, the sparkling water is ready. You can unscrew the carbonating bottle and enjoy it now.
