Working on a ice machine with R-12. CC Dickson co. told me that R-402b was recomended by the manufacture for replacement. Anyone used this stuff?? I noticed that it has propane in it. Thought that wasn't good. And as for charging a unit with a blend do you just charge it as a liguid on the low pressure side? Thanks for all the help. Kevin
Sorry I meant R-402a instead of b. There are way too many diff. kinds out there.
