Thanks for the info Benzmac. I'll keep an eye on the sight glass. Right now I have steady bubbles at all times.

Thanks for the pressure tables David. I imagine that most A/C systems are pretty much standard, but I have come to not rely on standards when dealing with the Benz, unless it's Benz standards.

With our little heat wave, I can tell you it's mighty toasty inland. Easily topping 100 degrees every day for the past five. A fully charged A/C will be a nice addition .
