PREPARING THE INSTALLATION LOCATION
Minimum Tools Needed
Locate the desired installation location (no lower than 18”inches from the ceiling). Using
a stud nder, 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 1 1/2”and no more than 18”from the ceiling.
* For the cx8800 special consideration needs to be used when selecting the installation
location. The system is wider than the typical 16" wall spacing and requires the removal
of at least one.
Using a ruler or measuring tape, measure vertically down 13.5" for cx2200, 20" down for
cx3300/cx4400, and 22.5 for cx8800. Mark another horizontal line parallel to the rst 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 op-
posite 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 your drywall out rst and cut through your studs when you have
clear understanding what is in the wall.
Now make the second horizontal cut from stud to stud on the line below the rst 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 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 rst 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 neces-
sary to frame the hole that you have just cut with upper and lower supports. These sup-
ports also provide solid material for the mounting bracket screws.
Using two 2x4s at 14.5”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 t snugly through the framed cut-out*.
* For the cx8800 it is recommended that the entire opening is framed. This system is
heavy and more attention to sturdy framing the better.
