AC to plateHX Chiller Conversion...56K Warning!

Ok, looks like I've got it holding a vacuum. Yes, it's only been ~20 minutes and I know: Stick my thumb in my nose and just wait! Got it! Check!


Anyway, seemed like there was something wonky going on: It would hold a vacuum for a few minutes and then start increasing fairly rapidly, but pretty much stop at around 5-10psi vacuum. Just didn't seem right the way it was behaving. I tried tightening the hose fittings. Realized at one point that I had the damn things on backwards! The valve pin pushers were up at the manifold. Could swear I checked that a few days ago. So, I got that straightened out, but it was still acting strangely. I thought maybe it had something to do with either the hoses or the vacuum pump. So, I pulled another vacuum, closed the manifold valves, removed the vacuum hose and capped the manifold off with an access valve cap, opened the manifold valves again.....and it's been holding a vacuum for ~30 mintues now....


Capped off:



So, now it's wait time.......
