Giải thích
With the compressor operating, the required recovery level for a small appliance is 90%, not 80%, so 82% is not enough. The technician should keep recovering with self-contained equipment until 90% is achieved or the alternative 4 inches Hg vacuum is reached. Venting any remaining refrigerant is prohibited regardless of the small charge.
