15.4.3 Reclaim Reclaim means to restore the recovered refrig- erant to a level equal to new (virgin) product speci- fications as determined by chemical analysis. Refrigerant that is recovered or recycled can be returned to the same system or other systems owned by the same person without restriction. However, if a refrigerant is to change ownership, that refrig- erant must be reclaimed. Reclaiming requires cleaning the refrigerant to the Air Conditioning and Refrigeration Institute (ARI) 700 standard of purity and chemically analyzing the restored refrig- erant to verify that it meets the standard. Reclaiming is a process normally available only at a manufac- turing or reprocessing facility. See Figure 15‑7. 15.5 Safe Disposal Requirements Equipment that is typically dismantled on site before disposal (commercial and industrial equip- ment) must have the refrigerant recovered in The cleanliness of recycled refrigerant does not have to meet the specifications for new refrig- erant, and chemical tests are not required. EPA regulations limit the use of recovered and/or recycled refrigerant to the same system or another system belonging to the same owner. Recovered or recycled refrigerant cannot change ownership by being sold or given away.
