WhisperKool XLT 3000, XLT 8000, XLT 4200 Cut vertical lines along the inside edge of the studs

•Once the horizontal lines have been cut, make vertical cuts using the inside edge of the studs as a guide. Once you have made both vertical cuts, you should have a rectangular hole in the sheetrock. Now you have to make the same hole on the other side of the wall. Since you already have one hole, this is an easy process. Using a nail, mark all four corners of the first hole by making nail holes through the sheetrock. Then on the other side of the wall, connect the holes with a pencil mark and cut.

Cut vertical lines along the inside edge of the studs.

•Sheetrock alone cannot support the weight of a 65-pound (or more) cooling system. Therefore, it is necessary to frame the hole that you have just cut with upper and lower supports. Using two two-by- fours 14.5 inches in length and eight 6d nails, secure the upper and lower supports to the right and left studs, just inside the sheetrock. Make sure that the internal height remains at 16" for the 1600, 3000 and 4200 models and 22.75" for the 6000 and 8000 models so that the WhisperKOOL system will fit snugly through the framed cut-out.

Frame the hole with two-by-four supports
