NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or a similar
material, drill 0.2 in. diameter (5 mm diameter)
holes in the wall and insert the sleeve anchors
provided. Secure the mounting plate to the
wall by tightening the screws directly into the
anchors.

When drilling the wall hole, be sure to avoid
wires, plumbing, nails, screws, and other
sensitive components.

Place the mounting plate against the wall in
a location meets the guidelines in the
Selecting an Installation Location step.
Refer to the Mounting Plate Dimensions
section for detailed information on
mounting plate sizes.
You must drill a hole in the wall for the refrigerant
piping, drainage pipe, and signal cable to pass
through in order to connect the indoor and outdoor
units.
Determine the location of the wall hole based on
the position of the mounting plate. Refer to the
Mounting Plate Dimensions (See Fig 4.5) to
assist you in determining the optimal position for
the hole, based on the type of mounting plate
provided with your unit.
Using a core drill, with a 3.54 in (90 mm)
diameter, drill a hole in the wall at a slight
downward angle, so that the indoor end of the
hole is higher than the outdoor end of the hole,
by approximately 0.2 in to 0.275 in (5 mm to 7
mm). This will ensure proper water drainage from
the indoor unit (See Fig. 4.3).
Insert the protective wall sleeve through the
hole of the inside wall, noting the amount it
protrudes from the exterior wall. Then, trim the
excess, with a utility knife or a saw, to make it
flush with the exterior wall. This will protect the
edges of the hole and help seal it when you
finish the installation process (See Fig 4.4).

NOTE
A cardboard template of the mounting plate is included
to be used as a more manageable way of determining
where to mount the mounting plate and drill the wall
hole. It can be placed against the wall in place of the
actual mounting plate for the previous step (See Fig 4.1).
