Giải thích
When recovering from a small appliance with self-contained (active) equipment and the compressor is operating, the technician must recover 90% of the refrigerant. If the compressor is not operating, the requirement drops to 80%. A working compressor helps push refrigerant out, so a higher recovery efficiency is required.
