Installation Summary - Indoor Unit
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 numbers of the indoor units match
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.
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:
NOTE ABOUT WALL HOLE:
Near any source of heat, steam, or
combustible gas
or clothing
Near any obstacle that might block air
circulation
Near a doorway
In a location subject to direct sunlight
If the
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 to pass through. 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 the left or right.

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.
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. 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 to pass through
which 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. Refer
to Fig. 3.3 wall hole diameter and install at a slight
angle to facilitate drainage.
2.
2.5 in (65 mm) for all others], 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 0.2 to
0.275 in (5 mm-7 mm). This will ensure proper
water drainage. (See Fig. 3.2)

Be extremely careful not to dent or damage the piping while bending them away from the unit. Any
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
technique, etc.
Based on the position of the wall hole,
relative to the mounting plate, choose the
side from which the piping will exit the unit.
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. 3.4). This will create a slot through which

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
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.
Based on the position of the wall hole, relative to
the mounting plate, determine the necessary
angle of your piping.
Grip the refrigerant piping at the base of the
bend.
Slowly, and 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
•Left-hand side
•Left rear
•Right-hand side
•Right rear

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.
NOTE ON DRAIN HOSE PLACEMENT
Make sure to arrange the drain hose according
to Fig. 3.6a.
DO NOT kink the drain hose.
DO NOT create a watertrap.
DO NOT put the end of drain hose in water
or a container that will collect water.
ENSURE UNUSED DRAIN HOLE IS PLUGGED
To ensure proper drainage, the drain hose must exit
the unit on the same side as the refrigerant piping.

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.

Double-check that all items are bundled in
accordance with Fig. 3.8
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
6. Feed the signal wire through this slot, from the
back of the unit to the front.
7. Facing the front of the unit, match the wire
colors with the labels on the terminal block,
to its corresponding terminal.
DO NOT MIX UP LIVE AND NULL WIRES
This is dangerous, and can cause the air
conditioning unit to malfunction.
8. After checking to make sure every connection
is secure, use the cable clamp to fasten the signal
cable to the unit. Screw the cable clamp down
tightly.
9. Replace the wire cover on the front of the unit,
and the plastic panel on the back.
Step 7: Wrap piping and cables
Before passing the piping, drain hose, and the signal
cable through the wall hole, you must bundle them
together to protect and insulate them, as well as
save space.
1. Bundle the drain hose, refrigerant pipes, and
signal cable according to Fig. 3.8.
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
damage.
