    Frankie and HM could probably tell you a story or two about that.....

    I've had a little experience with factory installed smoke, too.

    i do not know if i told you guys about my last mishap???

    40 ton carlyle semi!

    new 80 ton carrier split!

    low suction high superheat! duh the usual!!!

    low amp draw!!! duh!!!

    vav system, 6 compressors, 6 unloaders 3 condensers, 18 stages of cooling!!!

    I did what any good mechanic would do and added like 200 lbs r22 to get the suction up but eventually my superheat was very low!!!

    I finally tweaked a bunch of krap to get it to run well and suction pressure up to about 65 lbs, not bad for a big split fully loaded!!!

    ended up with 7.4 degrees superheat fully loaded on a hot day!! ofcourse it is vav with a 150 hp vfd!!!!!!

    anyhow as you guessed the next year/ last week!
    it shorted to ground,'

    changed it and when i disconnected the suction service valve/king valve!!!!!

    guess what i found between the service valve and the compressor!!!
    from the factory ofcourse!!!!!





    A RED 2" PLASTIC CAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!



    i think blue oval is going to be paying for this one!!!!!!!!!!!!!!!

    i found this once before on a 100 ton trane e compressor but the symptoms were much worse and it was a chiller with a factory charge!!!
    so i pumped it down and found it easy!


    found another factory similar!!!

    carrier 30 rb chiller kept pumping down?????????????????????????????????


    keep in mind it is a packaged chiller!!!!!!!!!!!!!!!!!

    found a rubber plug from a piece of acr copper stuck right before the EEV!!!!!!!!!!!!!!!!!!!!!!!!!

    not so easy to find!!!!!!!!!!!!!!!!!!!

    ofcourse first i replaced the EEV!!!!!!!!!!!!!!!!!!!
