    How to use a vacuum pump and recovery machine
    My question is when you vacuum down a condenser unit on a 3 ton do I vacuum out of the low side only are do I use both high and low side of manifold gage, my pump is a 6cfm yellowjacket. The same question for the recovery machine do I use the low side only are low and high sides both to recover refrigerant.

    Well, think about it. You either have a TXV or an orfice somewhere in the line.

    2. Will any harm be done if you vacuum from both sides?
