Giải thích
Refrigerant must be recovered from small appliances to the required level (80%/90% or 4 inches Hg) before the units are discarded, and knowingly venting is prohibited. Cutting the lines to release refrigerant is illegal venting. A signed record confirming recovery may be required before final disposal by a scrap facility.
