330 Express - Helm AC Cold Air Intake

[Viking88rd]

The cold air intake for helm AC appears to have a dirt/dust filter which is positioned behind the square louvered vent assembly. Trying to figure out how to remove the filter. The cold air intake for the cabin AC has an easily removable louvre panel. Helm assemble seems different. Has anyone tackled this maintenance chore......before I end up breaking something.

Follow-up: Spoke with Grady Customer Service and received tech support. The whole plastic assembly (outer frame and attached louvers) comes off in one piece.....attached to inner assembly by 4 detents. It's a little different than the cabin intake where only the louvers come out. Problem solved.
