Issue / Question:
This is a class A Allegro motor that has 134a a/c system in it. It has not be used in years and is very low on freon. I want to change the dryer, vacuum it down and check for leaks. After all this, what else do I have to prior to using ice32? Thank you

Answer:
Hey you don’t want to go back with 134, we got the alternative R-12 refrigerant called FR-12 and it works a lot better then 134, then we could install the ICE.
