  1. 90 percent
  2. 60 percent
  3. 80 percent ✔

Why: A broken compressor can't help push refrigerant out, so EPA lowers the target to 80 percent. If the compressor works, the target is 90 percent. A four-inch vacuum is an alternative to either percentage.

Huh, didn't know that: For dead compressors, EPA's Type I topics list heating and sharply striking the compressor to help free the refrigerant.
