Step 2: Attach mounting plate to wall
The mounting plate is the device on which you will mount
the indoor unit.
1. Remove the screw that attaches the mounting plate to
the back of the indoor unit.
2. Place the mounting plate against the wall in a location
that meets the standards in the
Select Installation
Location
step. (See
Mounting Plate Dimensions
for
detailed information on mounting plate sizes.)
3. Drill holes for mounting screws in places that:
•
have studs and can support the weight of the unit
•
correspond to screw holes in the mounting plate
4. Secure the mounting plate to the wall with the screws
provided.
5. Make sure that mounting plate is at against the wall.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar material,
drill 5mm-diameter holes in the wall and insert the sleeve
anchors provided. Then secure the mounting plate to
the wall by tightening the screws directly into the clip
anchors.

Step 3: Drill wall hole for connective piping
You must drill a hole in the wall for refrigerant piping, the
drainage pipe, and the signal cable that will connect the indoor
and outdoor units.
1. Determine the location of the wall hole based on the position
of the mounting plate. Refer to
Mounting Plate
Dimensions
on the next page to help you determine the
optimal position. The wall hole should have a 65mm
diameter at least, and at a slightly lower angle to facilitate
drainage.
2. Using a 65-mm core drill, drill a hole in the wall. Make
sure that the hole is drilled at a slight downward angle, so
that the outdoor end of the hole is lower than the indoor end
by about 5mm to 7mm. This will ensure proper
water drainage.
(See Fig. 5.3)
3. Place the protective wall cuff in the hole. This protects the
edges of the hole and will help seal it when you finish the
installation process.
CAUTION
When drilling the wall hole, make sure to avoid wires,
plumbing, and other sensitive components.
