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.
Refer to the following diagram to ensure
proper distance from walls and ceiling:
15cm (5.9in) or more
2.3m (90.55in) or more
12cm (4.75in)
or more
12cm (4.75in)
or more
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.
● Secure the mounting plate to the wall
with the screws provided. 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
1. Determine the location of the wall hole
based on the position of the mounting
plate. Refer to Mounting Plate
Dimensions.
2. Using a 65mm (2.5in) or 90mm (3.54in)
(depending on models )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.
3. Place the protective wall cuff 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.

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.
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. This will create a slot through
which your piping can exit the unit. Use
needle nose pliers if the plastic panel is
too difcult to remove by hand.
Knock-out Panel
3. 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.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor
unit from four different angles: Left-
hand side, Right-hand side, Left rear,
Right rear.
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 5: Connect drain hose
By default, the drain hose is attached to the
lefthand side of unit (when you’re facing the
back of the unit). However, it can also be
attached to the right-hand side. To ensure
proper drainage, attach the drain hose on the
same side that your refrigerant piping exits the
unit. Attach drain hose extension (purchased
separately) to the end of drain hose.
● Wrap the connection point rmly with
Teon tape to ensure a good seal and to
prevent leaks.
● For the portion of the drain hose that will
remain indoors, wrap it with foam pipe
insulation to prevent condensation.
●Remove the air lter and pour a small
amount of water into the drain pan to make
sure that water ows from the unit smoothly.
NOTE ON DRAIN HOSE
PLACEMENT
Make sure to arrange the drain hose
according to the following gures.
CORRECT
Make sure there are no kinks
or dent in drain hose to ensure
proper drainage.
NOT CORRECT
Kinks in the drain hose
will create water traps.
NOT CORRECT
Kinks in the drain hose
will create water traps.
NOT CORRECT
Do not place the end of the
drain hose in water or in
containers that collect water.
This will prevent proper
drainage.
PLUG THE UNUSED DRAIN HOLE
To prevent unwanted leaks
you must plug the unused
drain hole with the rubber
plug provided.

Step 7: Wrappiping and cables
Before passing the piping, drain hose,
and the signal cable through the wall hole,
you must bundle them together to save
space, protect them, and insulate them (Not
applicable in North America).
1. Bundle the drain hose, refrigerant pipes,
and signal cable as shown below:
Indoor Unit
Space behind unit
Refrigerant piping
Insulation tape
Signal wire Drain hose
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 overow, which can lead to re
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.
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).

Page 09-GB

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 rmly on
mounting by applying slight pressure to
the left and right-hand sides of the unit.
The unit should not jiggle or shift.
6. 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.
7. Again, check that the unit is rmly
mounted by applying slight pressure to
the left and the right-hand sides of the
unit.
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.
Wedge
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

Refrigerant piping
Connection
Refrigerant Piping Connection
When connecting refrigerant piping, do not let substances or gases other than the specied
refrigerant enter the unit. The presence of other gases or substances will lower the unit’s
capacity, and can cause abnormally high pressure in the refrigeration cycle. This can cause
explosion and injury.
Note on Pipe Length
The length of refrigerant piping will affect the performance and energy efciency of the
unit. Nominal efciency is tested on units with a pipe length of 5 meters (16.5ft) ( In North
America, the standard pipe length is 7.5m (25’)). A minimum pipe run of 3 metres is required
to minimise vibration & excessive noise. In special tropical area, for the R290 refrigerant
models, no refrigerant can be added and the maximum length of refrigerant pipe should not
exceed 10 meters (32.8ft).
Refer to the table below for specications on the maximum length and drop height of piping.

Connection Instructions – Refrigerant Piping
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and are them properly. This will
ensure efcient operation and minimize the
need for future maintenance.
1. Measure the distance between the indoor
and outdoor units.
2. Using a pipe cutter, cut the pipe a little
longer than the measured distance.
3. Make sure that the pipe is cut at a
perfect 90° angle.
90°
Oblique Rough Warped
DO NOT DEFORM PIPE WHILE
CUTTING
Be extra careful not to damage, dent, or
deform the pipe while cutting. This will
drastically reduce the heating efciency of
the unit.

Step 2: Remove burrs
Burrs can affect the air-tight seal of
refrigerant piping connection. They must be
completely removed.
1. Hold the pipe at a downward angle to
prevent burrs from falling into the pipe.
2. Using a reamer or deburring tool,
remove all burrs from the cut section of
the pipe. PipeReamer
Point down
Step 3: Flare pipe ends
Proper aring is essential to achieve an
airtight seal.
1. After removing burrs from cut pipe,
seal the ends with PVC tape to prevent
foreign materials from entering the pipe.
2. Sheath the pipe with insulating material.
3. Place are nuts on both ends of pipe.
Make sure they are facing in the right
direction, because you can’t put them on
or change their direction after aring.

Copper pipe
4. Remove PVC tape from ends of pipe
when ready to perform aring work.
5. Clamp are form on the end of the pipe.
The end of the pipe must extend beyond
the edge of the are form in accordance
with the dimensions shown in the table
below.

then inspect the end of the pipe for
cracks and even aring.
Step 4: Connect pipes
When connecting refrigerant pipes, be
careful not to use excessive torque or to
deform the piping in any way. You should
rst connect the low-pressure pipe, then the
high-pressure pipe.

CAUTION
• Oil traps
If the indoor unit is installed higher than
the outdoor unit:
-If oil ows back into the outdoor unit’s
compressor, this might cause liquid
compression or deterioration of oil
return. Oil traps in the rising gas piping
can prevent this.
An oil trap should be installed every
10m (32.8ft) of vertical suction line riser.
