    Size matters not sure there is enough room to stick 2 compressors in there for the foot print of the unit I agree with #2 sometimes chillers are oversized. Since most copeland tandems come as a complete unit cost cancels out. Dealing with smaller chillers like that most of the jobs are not professionally engineered it more of a rough guestimate.
    UA 100

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    Well, i do know these guys added a secondary loop and tried to run the machine through 1" pipe. It was short cycling like crazy.

    Well, the customer knew they could not possibly run a 10 ten system on 1" pipe. But, they did think the unit was a true varible speed "digital" scroll and it would be ok ! Serious!!!

    P.S. I just saw your edit a little bit ago!! I'll tell them to call you next time!!

    With the Micro coils the head will spike at startup then come back down to normal operating conditions. On a hot day it should not spike much over five hundred psig. If you must weigh in the charge subtact about five percent of what it says on the tag. If you overcharge just a little, it will trip. There should be a charging procedure in the OM book, that is the best way to charge it up. Again, if you have any restriction in the drier you will have problems.

    I know i didn't want to add the dryer. Would have been much easier just to go back in w/ the 165s. But, my Boss talked the owner into doing the replacable core as thier maintenace men will be able to replace it on the fly as needed!!!

    I guess the boss wins over common sense what is there a whopping 9 pounds or refrigerant in that machine.
