Remove the pink part from the bottom of the Terra bubbler by pressing the pins as shown in the included instructions and pulling the unit down. DUO and ART bubblers require a small piece of the body to be cut out of the cylinder compartment to allow the cylinder to be installed into the compartment. <br><br> 2. Screw the quick adapter with inserted flat seal onto a regular TR21-4 valve. Fits perfectly to our 425g CO2 cylinders, but of course also to cylinders from other manufacturers such as Crystal 2.0, Penguin, Cool and Aqvia. IMPORTANT: If the adapter does not screw into the handle of the CO2 cylinder, the cylinder is not compatible with this adapter. If you have any questions, we will be happy to answer them. <br><br> 3. Place the 425g bottle in the Soda DUO, Art or Terra and connect as usual by pulling down on the quick release and pushing into the dispenser until the device locks into place. IMPORTANT: The TR21-4 valve hexagon screw (safety valve) must be facing outside the unit, not to the side or into the storage unit. <br><br> Why choose us? <br><br> What if you only have a blue CO2 bottle but are too lazy to go out to refill it? Or there is no refilling station nearby? <br><br> The improved WADEO quick adapter is designed for sparkling water heaters with pink CO2 bottles. If you only have a blue CO2 bottle, take this adapter home and fill the blue bottle directly, then connect the adapter and you can use it on the Terra/Duo/Art series Sodastream soda machine. <br><br> Scope of supply: <br><br> 1*Quick Adapter <br><br><br> </div> <p></p>
