@Illinoisfarmer has an uncanny eye for the obvious detail when it comes to redneck engineering. I have said it before and I will say it again:"

You are truly a man outstanding in his field

Seriously guys. Why the attitude? Obviously, the company long known for redneck mobile climate control solutions has expanded into commercial equipment. Don't be jealous!

Seriously, as far as Ed's post, I'd bet a beer that the thing is powered by an extension cord inside the make-up unit connected to one leg of the three phase on the load side of the contactor. Since there's probably no neutral up there, I'd guess they are using the equipment ground for a neutral. I'd also guess that the filter has been removed - although I suppose it doesn't really matter in this particular application.

Now we are getting into some really interesting territory. Do you set the window unit to high cool and just plug it into an outlet that is operated by a sail switch and contactor, or do you put that stuff inside the window shaker?

Perhaps Paul can do a video and I can make up some outlandish convoluted wiring diagram.

Face Plant

Now………Did they get paid to do that?

Looks like a gas fired make up air unit that had no cooling ………but it does now!!!!!

is anyone here familiar with the concept of the AC booster?

is this something new? I don’t recall seeing it before I retired.
