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 ammable 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 xed 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.

Step 2: Attach mounting plate to wall
The mounting plate is the device on which you will mount the
indoor unit.
Remove the screw that attaches the mounting plate to the back
of the indoor unit.
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.)
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
Secure the mounting plate to the wall with the screws provided.
Make sure that mounting plate is at against the wall.
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.
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.
Using a 65mm (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 )
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.
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.
Refer to the following diagram to ensure proper distance from walls
and ceiling:

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 aring and are torque requirements, 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.
3.3). 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.

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
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, 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.
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.

Before installing a wall-mounted unit, make sure that the wall
is made of solid brick, concrete, or of similarly strong material.
The wall must be able to support at least four times the weight
of the unit.
Step 4: Connect signal and power cables
The outside unit’s terminal block is protected by an electrical
wiring cover on the side of the unit.
A comprehensive wiring diagram is printed on the inside of the
wiring cover.
Mark the position of bracket holes based on dimensions in the Unit
Mounting Dimensions chart.
Pre-drill the holes for the expansion bolts.
Clean dust and debris away from holes.
Place a washer and nut on the end of each expansion bolt.
Thread expansion bolts through holes in mounting brackets, put
mounting brackets in position, and hammer expansion bolts into
the wall.
Check that the mounting brackets are level.
Carefully lift unit and place its mounting feet on brackets.
Bolt the unit rmly to the brackets.
If you will install the unit on a wall-mounted bracket, do the
following:
CAUTION Remove the electrical control board cover from the outdoor
unit by loosening the screw.
Connect the connective cables to the terminals as identified
with their respective matched numbers on the terminal block
of indoor and outdoor units.
Secure the cable onto the control board with the cord clamp.
To prevent the ingress of water, form a loop of the connective
cable as illustrated in the installation diagram of indoor and
outdoor units.
Insulate unused cords (conductors) with PVC-tape. Process
them so they do not touch any electrical or metal parts.
