That all sounds right. I had one of the loaders too, but removed it. Mainly because for the most part you can't really see the cans being loaded and it did the same thing for the most part only like 3 cans before an issue.
When the cans load, they are pushed in the reefer, just as you would do by hand. Problem is they are being pushed onto a rubber belt. So they don't slide very easily when being pushed in my the loader itself.
When you operate the reefer it goes through a cycle, then stops. Depending where the first can is on the belt, the can may not com out on the first cycle (as the can as you run down the belt to get into position to exit the reefer) and you have to run another cycle, so that is normal. It just depends how far down the belts you pushed in the cans when you loaded them.
