You do have to seperat the different refrigerants, that I am certain of.
What I am still hoping to find out if you can sell the used refrigerant back to a supply house. I don't want to walk in to a supply house and ask looking like an idiot. Well I guess its really too late for that.
I got my license thru a local community college. The class and test were conducted by the instructor. We never touched any of the machines. I am also wondering if a Promax Amprobe RG5000 is good enough machine to get started with? Thanks in advance, Mike.
