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
standards 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
A location at least 40 in. (one meter) away
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.

the unit

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. Secur the mounting plate to the wall with
the screws provided.
5. Make sure that the 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 0.2 in. diameter (5 mm diameter)
holes in the wall and insert the sleeve anchors
provided. Then secur 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 at least a 2.5 in.
(65 mm) diameter, and be at a slightly
downward sloping angle to facilitate drainage.
2. Using a 2.5 in. (65 mm) core drill, drill a hole
in the wall. Ensure that the hole is drilled at
a slightly downward sloping angle, so that the
outdoor end of the hole is lower than the indoor
end by about 0.2–0.275 in. (5–7 mm). This will
ensure proper water drainage. (See Fig. 3.2.)
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.

CAUTION
Be extremely careful not to dent or damage the piping while bending them away from the unit. Any dents
in the piping will affect 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
difficult to remove by hand.
Knock-out Panel
3. Use scissors to cut down the length of the
insulating sleeve to reveal about 6 in. (15
cm) 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”
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
the piping during the process.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from
four different angles:
• Left-hand side
• Left rear
• Right-hand side
• Right rear

towards the hole. Do not dent or damage

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 firmly with
Teflon tape or clamp 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

Step 6: Connect signal cable
The signal cable enables communication
between the indoor and outdoor units. You
must first choose the right cable size before
preparing it for connection.
Cable Types
• Indoor Power Cable (if applicable):
• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-F
Minimum Cross-Sectional Area of
Power and Signal Cables
CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal
cable, fuse, and switch needed is determined
by the maximum current of the unit. The
maximum current is indicated on the
nameplate located on the side panel of the
unit. Refer to this nameplate to choose the
right cable, fuse, or switch.
TAKE NOTE OF FUSE SPECIFICATIONS
The air conditioner’s circuit board (PCB) is
designed with a fuse to provide overcurrent
protection. The specifications of the fuse
are printed on the circuit board. For example:
T3.15A/250VAC, T5A/250VAC, etc.
1. Prepare the cable for connection:
a. Using wire strippers, strip the rubber jacket
from both ends of signal cable to reveal
about 6 in. (15 cm) of the wires inside.
b. Strip the insulation from the ends of
the wires.
c. Using wire crimper, crimp u-type lugs on
the ends of the wires.
PAY ATTENTION TO LIVE WIRE
While crimping wires, make sure you clearly
distinguish the Live (“L”) Wire from other wires.
2. Open front panel of the indoor unit.
3. Using a screwdriver, open the wire box cover

bundle them together to save space, protect
them, and insulate them.
1. Bundle the drain hose, refrigerant pipes, and
signal cable according to Fig. 3.12.
Indoor Unit
Space behind unit
Refrigerant piping
Drain hose
Signal wire
Insulation tape
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 frigerant 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. 3.12..
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
hook of the mounting plate.
5. Check that unit is hooked firmly on mounting
by applying slight pressure to the left-hand
and right-hand sides of the unit. The unit
should not jiggle or shift.
