I just received my Nautilus 2 today. After taking it out of the box, I unscrewed the top to add some juice but the coil unscrewed itself from the bottom and stayed with the top. I unscrewed it from the top and screwed it tightly into the bottom. After screwing the top back on and off again to test, the coil again stayed with the top.
Am I doing something wrong, or did I receive a faulty tank?
(Note: I did just check the security code, and it came up authentic.)
