I have 3 Kingtec K10 AC units. They were from a project years ago and have been sitting. I don’t know whether they were modified but they need to go away or they are going in the dumpster.
Finally got around to getting these down and taking some pics. They appear to have been on a shelf since 2010. Looks like 5 ac units, 2 small, 3 big. I hate to throw these away, seems like someone could use them for something.
