My donor machine was free, but had no history. For all I knew, it was a total burnout.
I evacuated the system and let it sit for a week. No micron gauge, but no discernible loss in pressure either. If it leaks, it's slow.
Also jogged the compressor for the first time. Hermetic 3 ton Tecumseh reciprocating. Ohm metered before I ran it for the first time, and that looked good.
Still waiting for parts. TXVs and distributors should be here any day now.
Figured I'd get started by chopping out the old cap tube. Pressure tested with compressed air. Pressure dropped a few pounds. I was unsure if it was because of temperature differences, or a leak, so I threw it in the tub.
My new joints are tight, but there is a very small 1 bubble/min pinhole from evaporator itself. Good enough to get started. If it looses gas at an annoying rate, I know where to find it.
