1. Place your sparkling water maker on a flat sturdy surface in an upright position.
2. Remove the back cover.
3. Insert the gas cylinder into the cylinder holder located on the underside of the carbonating button and screw it in, twisting clockwise. Apply gentle pressure until it is firmly held in place. Hand-tighten only, DO NOT use tools.
4. Replace the back cover so that it clicks into place.
5. You're all ready to carbonate! Bask in that bubbly and enjoy :)
How do I install the gas cylinder in my sparkling water maker?
