So I’ve read a lot lately about vacuum ranges And got questions, I’ve read that on a r-22system with mineral oil as long as the decay test is below 1000 microns if doing a repair then it’s fine but a poe system needs to remain below 500 My question is what if your changing a compressor in a r22 system but the replacement compressor has Poe oil in it Does it now have to stay below 500 microns, does Poe travel with r-22 like it does with 410a?
