10 CFR 429.158: Product determined noncompliant with regional standards.

(a) If DOE determines a model of outdoor unit fails to meet the applicable regional standard(s) when tested in a combination certified by the same manufacturer, then the outdoor unit basic model will be deemed noncompliant with the regional standard(s). 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.
