Through wall A/C unit. Unprotected opening or not?

Hello to all,

How do we properly annotate on the ORI-B1-1802. through-wall A/C unit?

Would a through-wall a/c unit be considered an unprotected opening if the wall a/c unit shares the primary roof structure? Please provide sources.

I have attached a picture below.

Thanks for the help.

Show us a photo of one that is connected to the primary roof structure. Most window units are removable and therefore ok for deployable shutters. Wall units usually are not readily removable for shuttering. There are no definitive resources for what to do with A/C units or pet doors. Just use common sense and remember that non-permanent storm panels must be “ready for deployment”.
