An air conditioning unit sits on an equipment pad over a drain pan with a one-inch minimum clearance. A two-inch waste line runs from the equipment with a variable length per the roof plan, maintaining a one percent minimum slope below the roof. The vent extends up through the roof at a location coordinated with the floor plan. The assembly includes a trap and vent configuration routing waste from room RR-1 as indicated.
