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.

CAUTION
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 that 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 2.5 in (65 mm) or 3.54 in (90
mm) diameter (depending on model), 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)
.
NOTE:
When gas piping is 5/8 in (16 mm) or larger, the
wall hole should be drilled with a core drill
that has a diameter of 3.54 in (90 mm).
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).
