circulation
Near a 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 left or right.
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)

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 2.5in
(65mm) diameter at least, and at a slightly
lower angle to facilitate drainage.
2. Using a 2.5in (65-mm) 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 0.2 to 0.275in (5mm-7mm). 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.
NOTE FOR CONCRETE OR BRICK WALLS:
If the wall is made of brick, concrete, or similar
material, drill 0.2in-diameter (5mm-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 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
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 remove by hand.
Use scissors to cut down the length of the
insulating sleeve to reveal about 6in (15cm) 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.
Fig. 3.3
Knock-out Panel
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 different angles:
• Left-hand side
• Left rear
• Right-hand side
• Right rear
Refer to Fig. 3.4 for details.
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.
Page 13
Fig. 3.4
Indoor Unit Installation
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 to ensure a good seal and
to prevent leaks.
Fig. 3.5
Make there are no
kinks or dent
in the
hose to ensure
proper drainage.
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
hsmoothly.
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.
NOT CORRECT
Kinks in the drain hose
will c eate water traps.r
Fig. 3.6
NOT CORRECT
Dents in the drain hose
will create water traps.
Fig. 3.7
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks you must plug
the unused drain hole with the rubber plug
provided.
NOT CORRECT
Do not place the end
of the drain hose in
water or in containers
that collect water. This
will prevent proper
drainage.
