    The green R-22 scale is showing Saturated Temp. - not PSI

    It would also be helpful to know what amperage the compressor is drawing, along with the other parameters the others have mentioned.

    no. higher subcooling values means lower condensing tempertures. the highest subcooling factor i have seen on a residential system is 18. i would call your distributor or armstrong to find proper subcooling. it is usually listed on the name plate. but i charge till system operates around 20 degree superheat at probalby 10 to 12 degrees subcooling.
    as far as the discharge stat it may be faulty or your superheat is real high.
