What do I check before tying duct into a VAV box?

Equipment Connections: RTU, AHU, VAV, Fans & Louvers.1 field-polished — equipment/submittal check

Check orientation, access, inlet/outlet size, controller/actuator side, hanger support, damper access, and whether the duct connection will block service or TAB.

Open in Field Rescue Open category

Field checklist

Check VAV tag and flow arrow
Keep actuator, reheat coil, controls, and service panels reachable
Support duct so the box is not carrying the run

Ask foreman

Before I tie into this VAV, can you verify the orientation and access side? I want to make sure the controller, damper, and service panel stay reachable.

Do not

Do not bury the controller, coil, damper, or access side behind duct, flex, insulation, or hangers.

Why it matters

Project drawings/specs, equipment submittals, manufacturer instructions, access/service clearance requirements, foreman direction, startup needs, and approved equipment connection details.
