VAV box flow arrow not checked
Follow the equipment/submittal/manufacturer connection requirement: not checking VAV box flow arrow.
Verify the VAV tag, flow direction, and service side before tying in. The box can be connected and still be wrong if the actuator, coil, controls, or access side gets buried.
Ask when service clearance, vibration isolation, controls, drain, filter/coil access, or manufacturer detail is unclear.
Watch out
Do not bury the controller, coil, damper, or access side behind duct, flex, insulation, or hangers.
Check
Identify equipment tag and connection side.
Check submittal/shop drawing/manufacturer detail.
Confirm service clearance and access panels.
Focus on the actual issue: not checking VAV box flow arrow.
Photograph or mark the condition if someone else needs to approve it.

Say this to your foreman
In Equipment Connections: RTU, AHU, VAV, Fans & Louvers, I'm looking at: VAV box flow arrow not checked. What should I verify before I cut, drill, seal, cover, move, or install?
