I believe this part indicates otherwise:

"The equipment used to recover refrigerant from appliances prior to their final disposal must meet the same performance standards as equipment used prior to servicing, BUT IT DOES NOT NEED TO BE TESTED BY A LABORATORY. THIS MEANS THAT SELF-BUILT EQUIPMENT IS ALLOWED AS LONG AS IT MEETS THE PERFORMANCE REQUIREMENTS. FOR MVACs and MVAC-like appliances, the performance requirement is 102 mm of mercury vacuum and for small appliances, the recovery equipment performance requirements are 90 percent efficiency when the appliance compressor is operational, and 80 percent efficiency when the appliance compressor is not operational."

. . . He also needs to have an EPA approved recovery unit from the looks of things.

That's sort of funny. If I blow up a working compressor, I don't need to recover as much?

Either way, I'm guessing if I let the recovery run to it's limit, 20" Hg, that well meets the 80 or 90%? Can't even imagine there'd be 10-20% left in the system at that pressure (vacuum). I guess, at least with the size of stuff I work on, like 100 tons or less.

I don't even know what an MVAC is.

I don't think "efficiency" refers to the volume of charge left in the system.

Then what does it refer to?

The amount of electricity used?

Can't possibly mean how fast it pulls out a charge.

I guess it does refer to the charge. Weird.

It only applies to small appliances recovery equipment, though. Not the stuff we use.
