rayin Report post Posted February 5, 2020 Thank you for sharing that information. I knew my SCS/Frigette system took, 3.8# of R134, but had no clue to the details. BTW., that reminds me of a comment a guy made about 10 years ago on a different forum. He said to insulate the refrigerant line to the evaporator for better cooling_. 😆 That brought to mind a Confucius saying, " it is better to remain silent and be thought a fool, than speak and remove all doubt."
