It does not move air by itself. ### A simple example On a switchroom exterior wall, a selected intake louver can admit ventilation air while providing the specified weather protection. ### What the drawings help you do Use an outline or mounting drawing to plan where the equipment fits and where it attaches. Use a connection drawing to trace its electrical interfaces. A 3D model helps coordinate space; check the manufacturer's installation requirements separately. ### Terms - CAD: Computer-aided design files used to prepare drawings and models. - Revision: The recorded version of a drawing or model. Concept diagram: Outside or room air → Louver opening → Ventilation air path A simplified explanation of how this item works.
