I have a Snap On eco 134. I found this in a google search.
Having a hell of a time figuring out a replacement pump in the US. I got silly and yanked a compressor out of a portable ac unit We had around the house that ran on r22. I drained the oil out of it and replaced it with Pag oil plumbed it. It worked until I strayed to pull 134 from a can and put it in the recovery tank. Locked pump up and pooped breaker. now all three terminals shorted to case. So what happened? the 22 pump didn't like the pag oil? Im short on funds and need to come up with an economical solution. Can some one help me understand how the lines work? I know what discharge and suction are for but why do they have one port that says PROCESS. What kind of compressor do I need to replace this with? any help is appreciated
