With the release of the S-22 Topfill tank, we also released the S-22 Topfill Accessory.

This allows you to quickly and easily change your existing S-22 tank from bottomfill to topfill.

Once you have your Topfill Accessory, simply open up your existing S-22 tank as if you're going to fill it. If the S-22 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 S-22 ready to be filled and used.
