All that you have to do is slide the old part out that attaches to the cabinet of the air conditioner and slide in the new. You first slide in the accordian part of the extention panels and then the two plastic sections into the rails that hold them in place. No tools are required. Just make sure that you order the correct panel that needs to be replaced.
Very easily, I just removed the remainder of the accordion shaped panels from the frames, the slots on the a/c case exterior and in the process, slid out the frames completely from the a/c case exterior. I then completely cleaned the rubber residue from the frames, took the new Shutter Panels, "clicked" the one side of each back into each of the frames and then slid the other side of the Shutter Panels into the slots on the a/c case exterior, while positioning the frames into the slots on the top and bottom of the a/c case exterior. They just slide easily into place and I installed the a/c in the window, as usual and extended the frames with the new Shutter Panels as usual.
VERY VERY EASY FIX! Great site, showing the blow-up diagrams for any part you need to verify. Arrived much quicker than expected and reasonably priced. OUTSTANDING! Would highly recommend for any self-help appliance repair.
