TinnerFlow™3rd YearMechanical Room CoordinationRED · Stop and Get Direction
Equipment needs real service and coil pull access. If a duct blocks the removal lane, hold the run and coordinate a layout shift before it becomes future demolition.
A main duct can be installed perfectly and still be wrong if it blocks the AHU coil door or pull path. Maintenance access is part of the installation, not an afterthought.
Check the equipment submittal for service clearances and coil removal direction. If the duct blocks the lane, stop and coordinate offsetting, lowering, shifting, or rerouting before the run is fully built and insulated.
Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
