Damn, that looks great... you have a lot of skill and a lot of time!
More often than not they crimp the service ports, did you find some kind of hi/lo attachments for the R134a?
Have you had any training on refrigeration systems? Isn't there specialized gear involved with charging the system?
Just want to see if this is feasible for an average Joe DIY'er like me.
You need to install an access valve for no-serviceable A/C systems. They make piercing (solderless) and solder type access valves. From the picture, it looks like Yuri soldered in a valve.
I pulled a vacuum with a hand operated vacuum pump. It took a while, but I think it was pretty effective. The kegerator's placard called for 2.1 oz, and I kept the overall system volume pretty close to the same. However, I didn't have fine enough flow control over the R134, and I quickly overcharged the crap out of it. I will purge and carefully recharge before running the compressor for any length of time.
That's why I put a bit of effort into making sure that the new DIY line has nearly the same volume as the old one.Wouldn't your refrigerant charge amount change with the copper line opposed to the original coil?
