Replace blanket refrigerant cut-off assumptions with equipment-specific checks, and retain evidence for every exception. Keep federal product rules, local installation requirements and the contractor's commercial approval as distinct decisions.

This is a procurement and workflow guide, not a project compliance determination. No project location, equipment schedule or installation programme was supplied. The source review is current to 20 October 2026; recheck the controlling requirements when equipment is selected and before an affected bid is released.
