With the release of the S22 Topfill tank, we also released the S22 Topfill Accessory.


This allows you to quickly and easily change your existing S22 tank from bottomfill to topfill.


Once you have your Topfill Accessory, simply open up your existing S22 tank as if you're going to fill it. If the S22 tank has liquid left in it, it's best to turn it upside down first.


Unscrew the tank chamber from the airflow section of the tank, then take your Topfill Accessory and screw it onto the airflow section.


Turn the tank right-way-up, and you have your Topfill S22 ready to be filled and used.
