Diffuser Blowing Across an Open Refrigerated Case

This diffuser is aimed across an open refrigerated case. I checked the reflected ceiling plan and refrigeration layout, and the case lineup appears current. Can we verify the throw and final diffuser orientation before I finish this branch?

Stop if

Stop before changing case-area airflow, refrigeration access, life-safety work, specialty exhaust, structural support, equipment requirements, or manufacturer-specific details.

Watch out

Do not rotate the diffuser, relocate the branch, or invent a velocity rule to solve the conflict in the field.

Check

current mechanical and refrigeration drawings
grid/location and measured elevations
photo showing the duct and nearby cases/piping/fixtures
equipment or case submittal when applicable
what has already been checked
