After ensuring your AERIS is turned off and the MAX atomizer is removed, grab the MAX's silicone bumper and securely fit it onto the atomizer to ensure a snug fit.
Next, take the AERIS Adapter and place it onto the bottom of the AERIS’s silicone mouthpiece. Then, attach the MAX atomizer securely onto the AERIS base.
When the atomizer is secured onto the AERIS base, you're all set!
