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
Fig. 3.1-a

ePage 12 f
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 at 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. 3.2)
3. Place the protective wall cu in the hole. This
protects the edges of the hole and will help
seal it when you nish the installation process.
CAUTION
When drilling the wall hole, make sure to
avoid wires, plumbing, and other sensitive
components.

CAUTION
Be extremely careful not to dent or damage the piping while bending them away from the
unit. Any dents in the piping will aect the unit’s performance.
Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating
sleeve attached to the back of the unit. You must
prepare the piping before passing it through the
hole in the wall. Refer to the Refrigerant Piping
Connection section of this manual for detailed
instructions on pipe flaring and flare torque
requirements, technique, etc.
1. Based on the position of the wall hole relative
to the mounting plate, choose the side from
which the piping will exit the unit.
2. If the wall hole is behind the unit, keep the
knock-out panel in place. If the wall hole is to
the side of the indoor unit, remove the plastic
knock-out panel from that side of the unit.
(See Fig. 3.3 ). This will create a slot through
which your piping can exit the unit. Use
needle nose pliers if the plastic panel is too
dicult to remove by hand.
3. Use scissors to cut down the length of the
insulating sleeve to reveal about 15cm (6in)
of the refrigerant piping. This serves two
purposes:
• To facilitate the Refrigerant Piping
Connection process
• To facilitate Gas Leak Checks and enable
you to check for dents
4.
If existing connective piping is already
embedded in the wall, proceed directly to
the Connect Drain Hose step. If there is no
embedded piping, connect the indoor unit’s
refrigerant piping to the connective piping
that will join the indoor and outdoor units.
Refer to the Refrigerant Piping Connection
section of this manual for detailed instructions.
5. Based on the position of the wall hole
relative to the mounting plate, determine the
necessary angle of your piping.
6.
Grip the refrigerant piping at the base of the
bend.
7.
Slowly, with even pressure, bend the piping
towards the hole. Do not dent or damage the
piping during the process.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from
four dierent angles:
• Left-hand side
• Left rear
• Right-hand side
• Right rear
Refer to
Fig. 3.4 for details.

Step 5: Connect drain hose
By default, the drain hose is attached to the left-
hand side of unit (when you’re facing the back
of the unit). However, it can also be attached to
the right-hand side.
1.
To ensure proper drainage, attach the drain
hose on the same side that your refrigerant
piping exits the unit.
2.
Attach drain hose extension (purchased
separately) to the end of drain hose.
3.
Wrap the connection point rmly with Teon
tape to ensure a good seal and to prevent
leaks.
4.
For the portion of the drain hose that will
remain indoors, wrap it with foam pipe
insulation to prevent condensation.
5.
Remove the air filter and pour a small amount
of water into the drain pan to make sure that
water flows from the unit smoothly.
NOTE ON DRAIN HOSE
PLACEMENT
Make sure to arrange the drain hose
according to
Fig. 3.5 .
DO NOT kink the drain hose.
DO NOT create a water trap.
DO NOT put the end of drain hose in
water or a container that will collect
water.
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks you must plug
the unused drain hole with the rubber plug
provided.

DRAIN HOSE MUST BE ON BOTTOM
Make sure that the drain hose is at the bottom
of the bundle. Putting the drain hose at the
top of the bundle can cause the drain pan
to overflow, which can lead to fire or water
damage.
DO NOT INTERTWINE SIGNAL CABLE WITH
OTHER WIRES
While bundling these items together, do not
intertwine or cross the signal cable with any
other wiring.
2. Using adhesive vinyl tape, attach the drain
hose to the underside of the refrigerant pipes.
3. Using insulation tape, wrap the signal wire,
refrigerant pipes, and drain hose tightly
together. Double-check that all items are
bundled in accordance with Fig. 3.10.
DO NOT WRAP ENDS OF PIPING
When wrapping the bundle, keep the ends
of the piping unwrapped. You need to access
them to test for leaks at the end of the
installation process (refer to Electrical Checks
and Leak Checks section of this manual).
Step 8: Mount indoor unit
If you installed new connective piping to the
outdoor unit, do the following:
1. If you have already passed the refrigerant
piping through the hole in the wall, proceed
to Step 4.
2. Otherwise, double-check that the ends of the
refrigerant pipes are sealed to prevent dirt or
foreign materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant
pipes, drain hose, and signal wire through the
hole in the wall.
4. Hook the top of the indoor unit on the upper

Indoor Unit
Installation
If refrigerant piping is already embedded in
the wall, do the following:
1. Hook the top of the indoor unit on the upper
hook of the mounting plate.
2. Use a bracket or wedge to prop up the unit,
giving you enough room to connect the
refrigerant piping, signal cable, and drain
hose. Refer to Fig. 3.11 for an example.

3. Connect drain hose and refrigerant piping
(refer to Refrigerant Piping Connection
section of this manual for instructions).
4. Keep pipe connection point exposed to
perform the leak test (refer to Electrical
Checks and Leak Checks section of this
manual).
5. After the leak test, wrap the connection point
with insulation tape.
6. Remove the bracket or wedge that is propping
up the unit.
7. Using even pressure, push down on the
bottom half of the unit. Keep pushing down
until the unit snaps onto the hooks along the
bottom of the mounting plate.
UNIT IS ADJUSTABLE
Keep in mind that the hooks on the mounting plate are smaller than the holes on the back of the
unit. If you find that you don’t have ample room to connect embedded pipes to the indoor unit, the
unit can be adjusted left or right by about 30-50mm (1.25-1.95in), depending on the model. (See
Fig. 3.12
