I gotta say I'm impressed with your patience and restraint JP.
From reading this thread from start to finish I was sure that someone was pulling your chain but when I got to the point where they both stated that they were drinking I almost fell off my chair I was laughing so hard.
Plus this thread is almost four years old.
I was far more restrained 4 years ago...Quote:

You could measure all the tubing in the system piping and both coils and calculate the internal volume. Then work out where there would be various vapor volumes at the various pressures. And so forth.
Or you could look up the total receiver volume for the system refrigerant and then use 75% of that as the charge. If you have to bid the job - use 100%. <g>
I have worked on systems which could not be pumped down - but not very many.

Ahhhh. No I'm sticking with the fact that this thread is almost four years old. Now the POSTING are recently current but the thread at it's genesis is approaching four years of age. :grin2:Quote:

Always worked like a charm.
Oh, and BTW - I never use a digital gauge. Just seems to make me lose touch with whats goin' on. I dont even use a digital vacuum gauge - but instead I collect (yes, I have 4) of the Thermal Engineering vacuum gauges. They are ridiculously cheap if you can find them.
Maybe I am just too much of an ole codger :)
BTW - looks like ALL of those Sporland links are ded.
