The one I used to build mine from.
He has a part 2, with some extra pointers.

I adjusted mine for 10 seconds between cycles, and don't have any cooling time I need. Seems more consistent for the annealing.
I also added a computer fan to run continuously on the back end of mine with a 3d printed adapter to fit onto the end of it. I also have a computer fan on my desk blowing at the casings in the holder, towards the annealer while i'm working on them. Again more consistent for me.
I have run 200-300 cases on runs with no problems of over heating and shutting down.
How do I know its working, making a difference> I have lowered my ES and DS on my 50 shot strings on the 6.5 creed. Is it only the annealing, no, but it does help. I anneal after every firing now.
