    All right new to the forum. I have a problem I can't figure out
    15 ton chiller we had a leak. We evacted the system, fixed the leak.
    vaced the system, and recharged. High pressure is 130# low 25# machine says it takes 22 pounds of r-22. We put over 30 pounds in
    and the sight glass still bubbles. The bubble never went away during charging. air temp is about 90 degrees.
    Ideas????

    Yep
    "Right" is not the same as "Wise".

    Don't step on my favorite part of the Constitution just to point out your favorite part.

    Is that a mathematical approach?
    X3=66lbs X4=88lbs. More gogo gas run better. Lol!
