    Miller Picking Rooftop Units

    Hey guys, I am wondering if there is any info out there for a Miller Picking-- M# RM-25-HC S#086690 and a M#RM-20-HC S#086694. We are getting them pulled off the roof and need to know how much they weigh and if there is a core for the compressors. Any help would be appreciated. Thanks

    What are you going to do with the refrigerant?
    If you were a real tech, you'd solder a relay on that board and call it good to go.

    I do a triple evac with nitro to remove non condensables.

    I've heard about the recovery rag, sounds faster and easier than what I'm currently doing. Were do you pick those up?

    You know that guy in the alley who sells meat and speakers for real cheap? He has be known to have them. Be careful though because if he even hears anything remotely close to EPA....he will be gone.

    recovery tank in a container. annular space for dry ice.... refrigerant really moves, even w/o a pump.

    Very fast way to move a lot of R-whatever...

    Just so everyone knows and this info is available for others...

    Approximate weights:

    RM-10-HC 2800 lbs.
    RM-15-HC 3600 lbs.
    RM-20-HC 4800 lbs.
    RM-25-HC 6000 lbs.
    RM-30-HC 7200 lbs.
    RM-40-HC 7500 lbs.

    I say approximate weights because these units were built in 1966 and information on 52 year units is hard to find.
    Pretty much going by the marketing literature at that time, but I think it is close.

    I don't shop at Walmart. Their politics actually enter into the products that they sell; they make demands of their sellers to change things to meet their requirements.

    Any other place? Does the color of the rag make for a faster or slower recovery? What do I do with the rag once it has absorbed all of the refrigerant, do I take it back to the place I purchased it?
