Core (Universal)Câu 35 / 240
Before refrigerant that has been recovered from one owner's system can be sold to a different owner, it must be:
a.Simply filtered on the truck and relabeled
b.Recycled through a single-pass filter-drier
c.Reclaimed to the AHRI 700 purity standard by a certified reclaimer
d.Mixed with virgin refrigerant to dilute impurities
Giải thích
Used refrigerant can only be sold to a new owner after it has been reclaimed to the AHRI 700 purity standard, typically by an EPA-certified reclaimer. On-site recycling or simple filtering does not meet the standard for resale, and mixing with virgin refrigerant is not an acceptable substitute for reclamation. Reclaimed refrigerant must meet the same purity as new product.
