Locate the desired installation location (no lower than 18 inches from the ceiling). Using
a stud finder, locate the studs on either side of the center point, and mark them with
vertical lines.* Using a level and a pencil, mark a horizontal line on the wall between the
two studs, no less than 11/2 inches and no more than 18 inches from the ceiling.
* For the cx8800, special consideration needs to be used when selecting the installation
location. The system is wider than the 16 inches at which wall studs are typically spaced,
and will require the removal of at least one stud.
Using a ruler or measuring tape, measure vertically down 13.5 inches for the cx2200, 20
inches down for the cx3300/cx4400, and 22.5 inches for the cx8800. Mark another hori-
zontal line parallel to the first one.
Using a saw, cut along the uppermost horizontal line until your saw reaches the stud.
Turn the saw around, inserting it into the cut you have just made, and cut toward the
opposite stud so that you have a clean horizontal cut between the two studs. Be careful
not to cut into the studs themselves.*
* For the cx8800, cut out your drywall first and cut through your studs when you have a clear
understanding what is inside the wall.
Now make the second horizontal cut from stud to stud on the line below the first cut.
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 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.
Sheetrock alone cannot support the weight of a cooling system. Therefore, it is
necessary to frame the hole that you have just cut with upper and lower supports. These
supports also provide solid material for the mounting bracket screws.
Using two 2x4s at 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 the same so that the system will fit snugly through the framed cut-out.*
* For the cx8800, it is recommended that the entire opening be framed. This system is heavy
and the sturdier the frame, the better.
