Installation
Step 2-1 Attaching the mounting
bracket to the wall
1 Hold the mounting bracket against the wall at the
selected installation position (Step 1-3 on page 8),
making sure that the screw holes align with the center of
the studs in the wall. If the screw locations do not align
with the studs, use wall anchors.
CAUTION
࡛ The recommended best practice is to attach the
mounting bracket directly to the studs in the wall. If
you did not find a suitable location with studs (in Step
1-3 on page 8), or if the wall is concrete, you must
use wall anchors of a suitable type and weight capacity,
and install them according to the manufacturer’s
instructions. Failure to do so may cause the material
surrounding the joints to crumble over time and the
screws to be loosened and stripped. This may result
in the unit falling from the wall, which could cause
physical injury or equipment damage.
2 Using a level, make sure that the mounting bracket is
level, then mark the location of the screw holes on the
wall.
3 If using wall anchors, install them at the screw hole
positions, following the manufacturer’s instructions.
4 Using six field-supplied mounting screws and anchors (if
applicable), attach the bracket to the wall.

Step 2-2 Drilling the wall penetration
1 Determine the position of the hole through which the
piping bundle (consisting of power and communication
cables, refrigerant pipes, and the drain hose) will pass.
Consider the following:
ࣞ The hole inner diameter must be 2.5 inches
(65 mm).
ࣞ The recommended hole location is behind the unit
so that the hole and the piping bundle will not
be visible in the room. The minimum distances
between the hole and the mounting bracket are:

ࣞ If the hole cannot be positioned behind the unit,
find a position as close to the unit as possible. The
piping bundle that exits the unit and extends to the
hole will need to be attached to the wall and will be
visible inside the room.
ࣞ In relation to the bracket shown above, the unit is
shipped with the drain hose connection on the right, the
drain hose exits the unit on the left, and the refrigerant
pipes are bent to exit on the left. Thus, positioning the
hole to the left (A/B or outside the unit) requires the
least effort. If you position the hole to the right (C/D
or outside the unit) or below the unit, you will need to
move the drain hose connection to the left and bend
the pipes so that the hose and pipes exit to the right or
bottom. See the figure in step 3 on page 15.
