    Hint to would be responders: Contoller on the front of the panel is a UDC 3300, and panel has many more lights and relays than a North American built electric control JB.

    YOU gotta leak test!

    99% chance your problem is one of two. Your pump crapped out or you got a leak. No where is it written that a newleak can't occur within seconds of a contractor fleeing the jobsite.

    Start up went well. Got a little tripped up by a half ton tank that apparently has a broken dip tube, but the chiller showed no signs of any compressor problems.

    Got to wonder why

    DG & DM compressors are similar, but DM has that darned movable wall. Wonder if Carrier doubts compressors ability to make lift during slow acceleration.

    Orick, HCFC123 chillers are low pressure, and just because they run with a negative pressure doesn't mean they don't leak - distinction is that air goes from the outside in and the only refrigerant...

    Don't get too excited!

    Absorbers have large shares of some big city chiller populations. Most notably New York and Chicago. They are not at all common in the boonies.

  30. Why take a shortcut on this?

    RE-read step 2. (Purge is already isolated) Also, and especially in the case of HCFC123, you want to eliminate as much of the refrigerant as practical from the waste product before removal.
