In accordance with § 429.102(a)(10) , the outdoor unit manufacturer and/or private labeler is liable for distribution of noncompliant units in commerce.(b) If DOE determines a combination fails to meet the applicable regional standard(s) when tested in a combination certified by a manufacturer other than the outdoor unit manufacturer (e.g., ICM), then that combination is deemed noncompliant with the regional standard(s). In accordance with § 429.102(a)(10) , the certifying manufacturer is liable for distribution of noncompliant units in commerce.(c) All such units manufactured and distributed in commerce are presumed to have been installed in a region where they would not comply with the applicable energy conservation standard; however, a manufacturer and/or private labeler may demonstrate through installer records that individual units were installed in a region where the unit is compliant with the applicable standards.81 FR 45404, July 14, 2016, as amended at 87 FR 64586, Oct. 25, 2022 81 FR 45404, 8/15/2016; 87 FR 64586, 11/25/2022
