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.

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).
