How to use the Omicron O-Phos?

Hey,

A friend of mine just got his omicron o-Phos and asked me to put it together and load it while he's gone for so it'll be ready when he gets back in a little while. I thought I'd be able to just figure it out, but this shit is complicated. I've looked it up online but I've seen different parts and stuff in images on the Internet. I have here: the main part, with on one end a little part that you can screw off to find the part where you charge it, the battery inside, and on the other end(the end with the button) there's a little circular thing about a centimeter in that I'm assuming heats it up (I'm new to vapes). Not attached to it there's the little white circular thing, a rubber piece, and a black piece that's metal on the inside, and the funnel tool to load it. How the hell do you load this and use it? Attached is a pic of the parts.
Thanks, Cruz
