Hi Anfleet. First you will want to blow anything that is currently in the atty out through the threaded end. Meaning gently take some tissue and cup it around the threaded end of the atty and blow from the mouth end through the atty to expel any thing that may be left from manufacturing. The first blow through may not remove anything at all but if there is anything there you will be glad you arent
vaping it.
I do recommend a drip tip to make the blowing through easier. After you are confident that everything is out of the atty and empty,you should drop about three to five drops on the bridge.... thats the arc that runs above the ceramic cup. The ceramic cup is where the coil sits just below the bridge. Most newer attys dont have the gross primer in them but just to be sure take about five regular drags off the atty without inhaling, just puff then exhale.
You will notice when you start to get near when to re-drip once the vapor gets hot and a little harsh. Once you have burned through the first little bit of liquid you have loaded in there you will want to remove the atty from the battery and blow the rest of the liquid through the threaded end of the atty into yet another piece of tissue. Now you should have a seasoned atty ready to prime.
Drip another three to five drops in the atty and you should be ready to
vape. There is a bit of a learning curve to this and this is my own personal take on the ritual which should be modified as the particular atty may require. In the past some where loaded heavily with crud from new and required much more repetitive priming, burning,blowing and some where empty as could be and needed nothing more than a few drops and where all but ready to vape.
In my experience most attys took a bit of a break-in to reach a level where you could begin to learn when it was time to drip to re wet. You will get the hang of it the more you do it, most of the time I would know it was time to drip when the hits became more harsh than what I enjoyed.
