Installation Instructions – Indoor
Unit
PRIOR TO INSTALLATION
Before installing the indoor unit, refer to the
label on the product box to make sure that the
model number of the indoor unit matches the
model number of the outdoor unit.
Step 1: Select installation location
Before installing the indoor unit, you must
choose an appropriate location. The following
are standards that will help you choose an
appropriate location for the unit.
Proper installation locations meet the
following standards:
Good air circulation
Convenient drainage
Noise from the unit will not disturb other
people
Firm and solid—the location will not vibrate
Strong enough to support the weight of the
unit
A location at least one meter from all other
electrical devices (e.g., TV, radio, computer)
DO NOT install unit in the following
locations:
Near any source of heat, steam, or
combustible gas
Near flammable items such as curtains or
clothing
Near any obstacle that might block air
circulation
Near the doorway
In a location subject to direct sunlight
NOTE ABOUT WALL HOLE:
If there is no fixed refrigerant piping:
While choosing a location, be aware that you
should leave ample room for a wall hole (see
Drill wall hole for connective piping step)
for the signal cable and refrigerant piping
that connect the indoor and outdoor units.
The default position for all piping is the right
side of the indoor unit (while facing the unit).
However, the unit can accommodate piping to
both the left and right.
Indoor Unit
Installation

Page 12 
Refer to the following diagram to ensure proper distance from walls and ceiling:
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 flat against
the wall.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar
material, drill 5mm-diameter (0.2in-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
(2.5in) diameter at least, and at a slightly
lower angle to facilitate drainage.
2. Using a 65 mm (2.5in) 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 (0.2-0.275in). This will
ensure proper water drainage. (See Fig. 4.2 )
3. Place 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.
