1. Determine the location of the wall hole based
on the location of the outdoor unit.
2. Using a 2.5in/65mm or 3.54in/90mm
(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 0.5in/12mm. This will ensure proper water
drainage.
3. 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.
Step 4: Connect drain hose
The drainpipe is used to drain water away from
the unit. Improper installation may cause unit
and property damage.
CAUTION
• Insulate all piping to prevent condensation,
which could lead to water damage.
• If the drainpipe is bent or installed
incorrectly, water may leak and cause a
water-level switch malfunction.
• In HEAT mode, the outdoor unit will
discharge water. Ensure that the drain hose
is placed in an appropriate area to avoid
water damage and slippage.
• DO NOT pull the drainpipe forcefully. This
could disconnect it.
NOTE ON PURCHASING PIPES
Installation requires a polyethylene tube
(exterior diameter = 1.45-1.53in/3.7-3.9cm,
interior diameter = 1.26in/3.2cm), which can be
obtained at your local hardware store or dealer.
Indoor Drainpipe Installation
Install the drainpipe as illustrated in the
following Figure.
1. Cover the drainpipe with heat insulation to
prevent condensation and leakage.
2. Attach the mouth of the drain hose to the
unit’s outlet pipe. Sheath the mouth of the
hose and clip it rmly with a pipe clasp.
NOTE ON DRAINPIPE INSTALLATION
• When using an extended drainpipe, tighten
the indoor connection with an additional
protection tube to prevent it from pulling
loose.
• The drainpipe should slope downward at a
gradient of at least 1/100 to prevent water
from owing back into the air conditioner.
• To prevent the pipe from sagging, space
hanging wires every 39-59in/1-1.5m.
• Incorrect installation could cause water to
ow back into the unit and ood.
NOTE: When connecting multiple drain-
pipes, install the pipes as illustrated in the
following Figure.
1. Pass the drain hose through the wall hole.
Make sure the water drains to a safe location
where it will not cause water damage or a
slipping hazard.
NOTE: The drainpipe outlet should be
at least 1.9in/5cm above the ground. If it
touches the ground, the unit may become
blocked and malfunction. If you discharge
the water directly into a sewer, make sure
that the drain has a U or S pipe to catch
odors that might otherwise come back into
the house.
CAUTION
When drilling the wall
hole, make sure to avoid
wires, plumbing, and other
sensitive components.

codes and regulations, which may vary from
region to region.
INSTALLATION INSTRUCTIONS –
OUTDOOR UNIT
Step 1: Select installation location
Before installing the outdoor 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:
Meets all spatial requirements shown in
Installation Space Requirements above
Good air circulation and ventilation
Firm and solid - the location can support the
unit and will not vibrate
Noise from the unit will not disturb others
Protected from prolonged periods of direct
sunlight or rain
Where snowfall is anticipated, raise the
unit above the base pad to prevent ice
buildup and coil damage. Mount the unit
high enough to be above the average
accumulated area snowfall. The minimum
height must be 18 inches.
DO NOT install unit in the following locations:
Near an obstacle that will block air inlets and
outlets
Near a public street, crowded areas, or where
noise from the unit will disturb others
Near animals or plants that will be harmed
by hot air discharge
Near any source of combustible gas In a
location that is exposed to large amounts of
dust
In a location exposed to excessive amounts
of salty air
SPECIAL CONSIDERATIONS FOR
EXTREME WEATHER
If the unit is exposed to heavy wind:
Install unit so that air outlet fan is at a 90° angle
to the direction of the wind. If needed, build
a barrier in front of the unit to protect it from
extremely heavy winds.
See Figures below.
If the unit is frequently exposed to heavy rain
or snow:
Build a shelter above the unit to protect it from
the rain or snow. Be careful not to obstruct air
ow around the unit.
If the unit is frequently exposed to salty air
(seaside):
Use outdoor unit that is specially designed to
resist corrosion.

Page 13
Step 2: Install drain joint (Heat pump
unit only)
Before bolting the outdoor unit in place, you
must install the drain joint at the bottom of the
unit.
Note that there are two dierent types of drain
joints depending on the type of outdoor unit.
If the drain joint comes with a rubber seal
(see Fig. A), do the following:
1. Fit the rubber seal on the end of the drain
joint that will connect to the outdoor unit.
2. Insert the drain joint into the hole in the
base pan of the unit.
3. Rotate the drain joint 90° until it clicks in
place facing the front of the unit.
4. Connect a drain hose extension (not
included) to the drain joint to redirect water
from the unit during heating mode.
If the drain joint doesn’t come with a rubber
seal (see Fig. B), do the following:
1. Insert the drain joint into the hole in the
base pan of the unit. The drain joint will click
in place.
2. Connect a drain hose extension (not
included) to the drain joint to redirect water
from the unit during heating mode.
IN COLD CLIMATES
In cold climates, make sure that the drain hose
is as vertical as possible to ensure swift water
drainage. If water drains too slowly, it can freeze
in the hose and ood the unit.
Step 3: Anchor outdoor unit
The outdoor unit can be anchored to the
ground or to a wall-mounted bracket with bolt
(M10). Prepare the installation base of the unit
according to the dimensions below.

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
32.8ft/10m of vertical suction line riser.
The indoor unit is installed higher than the
outdoor unit
Refrigerant Piping Connection 7
When connecting refrigerant piping, do not let substances or gasses other than the specied
refrigerant enter the unit. The presence of other gasses 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
Ensure that the length of the refrigerant pipe, the number of bends, and the drop height between
the indoor and outdoor units meets the requirements shown in the following table:

CAUTION
If the outdoor unit is installed higher than the
indoor unit:
• It is recommended that vertical suction
risers not be upsized. Proper oil return to
the compressor should be maintained with
suction gas velocity. If velocities drop below
1,500fpm (feet per minute)/7.62m/s oil
return will be decreased. An oil trap should
be installed every 20ft/6m of vertical suction
line riser.
The outdoor unit is installed higher than the

Refrigerant Piping Connection
Instructions
CAUTION
• The branching pipe must be installed
horizontally. An angle of more than 10° may
cause malfunction.
• DO NOT install the connecting pipe until
both indoor and outdoor units have been
installed.
• Insulate both the gas and liquid piping to
prevent water leakage.
Step 1: Cut pipes
When preparing refrigerant pipes, take extra
care to cut and are them properly. This will
ensure e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.
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 eciency of the
unit.
Step 2: Remove burrs.
Burrs can aect 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.
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.

Page 17
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.
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
are form.
6. Place aring tool onto the form.
7. Turn the handle of the aring tool clockwise
until the pipe is fully ared. Flare the pipe in
accordance with the dimensions.
8. Remove the aring tool and are form, then
inspect the end of the pipe for cracks and
even aring.

Step 4: Connect pipes
Connect the copper pipes to the indoor unit
rst, then connect it to the outdoor unit. You
should rst connect the low-pressure pipe, then
the high-pressure pipe.
1. When connecting the are nuts, apply a thin
coat of refrigeration oil to the ared ends of
the pipes.
2. Align the center of the two pipes that you
will connect.
3. Tighten the are nut as tightly as possible by
hand.
4. Using a spanner, grip the nut on the unit
tubing.
5. While rmly gripping the nut, use a torque
wrench to tighten the are nut according to
the torque values in above table.
NOTE: Use both a spanner and a torque
wrench when connecting or disconnecting
pipes to/from the unit.
CAUTION
• Be sure to wrap insulation around the
piping. Direct contact with the bare piping
may result in burns or frostbite.
• Make sure the pipe is properly connected.
Over tightening may damage the bell mouth
and under tightening may lead to leakage.

Page 18
NOTE ON MINIMUM BEND RADIUS
Carefully bend the tubing in the middle
according to the diagram below. DO NOT
bend the tubing more than 90° or more than
3 times.
After connecting the copper pipes to the indoor
unit, wrap the power cable, signal cable and the
piping together with binding tape.
NOTE: 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.
6. Thread this pipeline through the wall and
connect it to the outdoor unit.
7. Insulate all the piping, including the valves
of the outdoor unit.
8. Open the stop valves of the outdoor unit to
start the ow of the refrigerant between the
indoor and outdoor unit.
CAUTION
Check to make sure there is no refrigerant leak
after completing the installation work. If there is
refrigerant leak, ventilate the area immediately
and evacuate the system (refer to the Air
Evacuation section of this manual).
