To replace the heating coil:
Turn the Vapeonly BCC upside down and screw off the connector. Pull out the old coil unit from the bottom base and replace it by pushing in a new one. It's very simple.

**Tip: If you are experiencing a dry vape, blow into the clearomizer. This will free any air bubbles that may be preventing liquid from getting to the wick adequately. You may also try dragging a little harder. This should eliminate the problem.
