The Vapouriz Fuse has a 'bottom fill' clearomizer tank, so needs to be filled by turning the clearomizer upside down, unscrewing the base and filling down the side walls. Be careful not to pour any liquid into the centre pipe and do not fill up past the top of this pipe.
The Vapouriz Tank is the same as above, but is filled from the top (by unscrewing the mouth piece) as opposed to the bottom.
My Vapouriz Fuse Kit was working and has now stopped working, but the battery button still lights up
If the battery is still working you'll need a new coil for your clearomizer (the chamber which holds your e-liquid). These usually last between two to eight weeks before they burn out and cease to work.
