Replacing The Coils

Holding the tank upside down grip the tank with one hand then grip the bottom ring of the tank with the other hand & unscrew and remove the tank base, once the base is removed the atomiser head (Coil Unit) is located in the centre of the tank base, unscrew and replace this part with a fresh head, do not over tighten, replace the tank base taking care not to over tighten, allow a minute or two for the juice to soak into the wicks before firing to avoid getting a dry burn (damaging the wicks in the atomiser head)
