Air conditioning

How many pounds does the system take? It says on the side both 3.00 and 5.25.

I stuck one of those retrofit kits (what a joke) on there today and put 3 pounds of R134A and a pound of that R12/R134A oil in it. It said in the kit to only put 85% of the R134A in that calls for the amount of R12. Well, that equates to ~2.5 pounds but the system sucked the contents out faster than I could turn the valve.

It doesn't get that cold. Then again, I'm used to systems that are a little older. You know, the kind that can be used for a refrigerator.

But anyway, what exactly does it mean by 3.00 and 5.25? Does it mean 5.25 dry and 3.00 wet? Does it mean 3.00lbs of R12 and 2.25lbs of oil?


Some of that stuff doesn't make sense now that I wrote it. I think it's the primer fumes. Anyway, I must go study for my last exam for the summer tomorrow morning.
