31. Any person who, while an air conditioning unit referred to in this Division is being serviced, becomes aware of a defect that may cause a halocarbon leak, or any person who repairs, modifies, converts or dismantles components that contain a halocarbon, must recover the halocarbon present in the unit. Prior to the recovery, the nature of the halocarbon must be identified using a device designed for that purpose. The halocarbon must be recovered by means of equipment whose effectiveness is equal to or greater than the standard indicated below and in force at the time the equipment is purchased, in respect of each type of halocarbon:(1) for the recovery of CFC-12, if the equipment simultaneously recycles the halocarbon: SAE Standard J1990: Recovery and Recycle Equipment for Mobile Automotive Air-Conditioning Systems, published by SAE International, an American standards body;
(2) for the recovery of CFC-12, in any case other than the case in paragraph 1: SAE Standard J2209 Refrigerant Recovery Equipment for Mobile Automotive Air-Conditioning Systems, published by the body referred to in paragraph 1;
(3) for the recovery of HFC-134a, if the equipment simultaneously recycles the halocarbon: SAE Standard J2210 or J2788 HFC-134a (R-134a) Recovery/Recycling Equipment and Recovery/Recycling/Recharging for Mobile Air-Conditioning Systems, published by the body referred to in paragraph 1;
(4) for the recovery of HFC-134a, in any case other than the case in paragraph 3: SAE Standard J2810 HFC-134a (R-134a) Refrigerant Recovery Equipment for Mobile Automotive Air-Conditioning Systems, published by the body referred to in paragraph 1;
(5) for the recovery of HFO-1234yf, if the equipment simultaneously recycles the halocarbon: SAE Standard J2843 R-1234yf [HFO-1234yf] Recovery/Recycling/Recharging Equipment for Flammable Refrigerants for Mobile Air-Conditioning Systems, published by the body referred to in paragraph 1; and
(6) for the recovery of HFO-1234yf, in any case other than the case in paragraph 5: SAE Standard J2851 Recovery Equipment for Contaminated R-134a of R-1234yf Refrigerant from Mobile Automotive Air-Conditioning Systems, published by the body referred to in paragraph 1.
