    When I worked out of Local 322 it was common.

    So it was always better for the customer to have the evacuation performed on Friday. <g>

    I thought anything higher than 400 microns was a leaker

    Just on how vacuums are done in the industry causes me to wonder how important they are.
    If shops are not really pulling adequate vacuums by industry standards shouldn't there be way more problems?
    I like vacuums myself but I also know some must not.
    Carrier might have suspected that vacuums were often not done or only partially when they advised the triple evacuation. Today the method is misinterpreted but a good idea in it's day.
    There are ways to remove moisture a lot faster and more complete but each seems to have a down side.
    Give me a relay with big enough contacts, and I'll run the world!

    You can be anything you want......As long as you don't suck at it.

    If a person wants to create a machine that will be more likely to fail...Make it complicated.

    There are industry standards and industry practices. Standard what is 100% correct, practice what ever it takes. Every company is different just like service people. The newer refrigerants vrs older refrigerant will push the companies to do the right thing. R22 used in high temp ac was very forgiving. Worked for a factory sevice on residual 22 servicemen not one vacuum pump purged everything. Had very few problems in pre reclaim days.
