The nice thing about these tanks is that they are a nice easy change, without needing to first remove any remaining liquid first. Simply remove the Tank from your device and then turn upside down, then unscrew the base in an anti-clockwise direction. Next hold the atomiser head and base section and twist apart from each other in an anti-clockwise direction. Replace the atomiser and reassemble in reverse order. Take Care with threads: When bringing items together that have threads - back them up in reverse direction until they engage properly, before turning in correct direction to tighten. This will reduce the possibility of cross threading. Do not over tighten threads. That's it, the coil for your Kanger Tank has been changed.
