Vacuum pump had more of a thick consistent smoke that was white. Didn't seem to have real strong odor, but definitely had an unusual one that I had not come across before. Refrigerant was 410A. Replaced leaking warranty TXV on condenser. Odor wasn't any of the normal additives like R11 Flush, Acid Away, etc. That I have ran across. I've heard that there were some bad and nasty chemicals out there that some people put in systems. Kind of worried. Would appreciate any information, factual information, good or bad, but at least some kind of idea and what the toxicity, effects and time period that I should be concerned about it.
Thanks for reading. Look forward to a response.
