STEP 1: WALL SLEEVE ADAPTER ORIENTATION
The wall sleeve adapter increases the depth of existing wall sleeves to accept deeper PTAC units. The adapter
mounts to the front of the existing sleeve inside of the room. The sleeve should be oriented so that the Stickout
Flange is inside the existing sleeve and the Fold-over Flange is positioned to the bottom front of the adapter
as shown in illustration.
