First make sure that what you get is what you need to fit the hole. Un screw the many screws from the top. You should have 6/8 screws inside to hold the inside cover. Mark it for a corner with tape. Remove the sealant from the outside, lift out unit. Clean all remaining sealant off. Temp fit and align up in hole. My screws did not line up so had to drill all new. Start in a corner and drill one, check alignment and then the next corner. Check Alignment and one more hole with screw. If everything is good drill the rest. I replaced all mine screws with new. Mark two spots with marker or tape. Remove and lay down beads of sealant. I went to Lowes and they have roll sealant. Start installing the screws and do not tighten down, just snug all the way around, Take two or three time around and just a 1/4 turn to you get even flow on the sealant flowing out.
