    I agree with Rider.
    Very nice machine and room.

    I cut my "chiller teeth" on such equipment.

    Those CVHA's, and earlier yet nearly identical PCV's, were always my favorite chillers to rebuild.

    I'll try, but it may be a while.

    I now see that I ignored one part of your first post - is this a 200 ton or 250 ton chiller? Probably a 200 ton, since that is what the building prints say. The...

    Not sure what literature you were looking at, but I think what you have is about the smallest size the CVHA came in. Perhaps you were misinterpreting the model number. Trane uses the fifth, sixth,...

    Plastic? Mine had some kind of vinyl over cardboard case. The "hinge" for the cover wasn't the problem, it was all four corners where the sides met. Two or three wraps of duct tape solved that.

    You should ask your Trane technician about the hours and starts ratio. I believe that is for a compressor, not the unit. It appears to be an excessive number of starts.

    Exactly.

    I only isolate components (windings, wiring, resistors, contactors,...) when I see an abnormal, or unexpected, result. To determine where the potential problem is.
