Install the unit by following local codes and
regulations, which may dier slightly from
region to region.
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
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.

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, 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.
The following is a list of dierent outdoor unit
sizes and the distance between their mounting

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.
Connection Instructions – Refrigerant Piping
• 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.
Be extra careful not to damage, dent, or
deform the pipe while cutting. This will
drastically reduce the heating eciency 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.
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 them 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.
CAUTION
NOTE: Use both a spanner and a torque wrench
when connecting or disconnecting pipes to/
from the unit.
• 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 13
6. After connecting the copper pipes to the
indoor unit, wrap the power cable, signal
cable and the piping together with binding
tape.
7. Thread this pipeline through the wall and
connect it to the outdoor unit.
8. Insulate all the piping, including the valves
of the outdoor unit.
9. Open the stop valves of the outdoor unit to
start the ow of the refrigerant between the
indoor and outdoor unit.
After completing the installation work, make
sure there is no refrigerant leak. If there is,
ventilate the area immediately and evacuate the
system (refer to the Air Evacuation section of
this manual).
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.
NOTE: DO NOT intertwine signal cable with
other wires. While bundling these items togeth-
er, do not intertwine or cross the signal cable
with any other wiring.
CAUTION

cause malfunction, electrical shock, or re.
5. If connecting power to xed wiring, install a
surge protector and main power switch with
a capacity of 1.5 times the maximum current
of the unit.
6. If connecting power to xed wiring, a switch
or circuit breaker that disconnects all poles
and has a contact separation of at least 1/8in
(3mm) must be incorporated in the xed
wiring. The qualied technician must use an
approved circuit breaker or switch.
7. Only connect the unit to an individual
branch circuit outlet. Do not connect
another appliance to that outlet.
8. Make sure to properly ground the air
conditioner.
9. Every wire must be rmly connected. Loose
wiring can cause the terminal to overheat,
resulting in product malfunction and
possible re.
10. Do not let wires touch or rest against
refrigerant tubing, the compressor, or any
moving parts within the unit.
11. If the unit has an auxiliary electric heater,
it must be installed at least 1 meter (40in)
away from any combustible materials.
12. To avoid getting an electric shock, never
touch the electrical components soon
after the power supply has been turned
o. After turning o the power, always wait
10 minutes or more before you touch the
electrical components.
13. Make sure that you do not cross your
electrical wiring with your signal wiring. This
may cause distortion and interference.
14. The unit must be connected to the main
outlet. Normally, the power supply must
have a impedance of 32 ohms.
15. No other equipment should be connected to
the same power circuit.
16. Connect the outdoor wires before
connecting the indoor wires.

After the conrmation of the above conditions, prepare the wiring as follows:
• Never fail to delegate an individual power circuit specically for the air conditioner. For the
method of wiring, use the circuit diagram posted on the inside of the control cover as a guide.
• The screws which fasten the wiring in the casing of electrical ttings are liable to come loose from
vibrations to which the unit will be subjected during the course of transportation. Check to make
sure they are all tightly fastened. (If they are loose, the wires could burn out.)
• Specication of power source.
• Conrm that the electrical capacity is sucient.
• See that the starting voltage is maintained at more than 90 percent of the rated voltage marked
on the name plate.
• Conrm that the cable thickness is as specied in the power source specication.
• Always install an earth leakage circuit breaker in a wet or moist area.
• The following could be caused by a voltage drop: The vibration of a magnetic switch (which will
damage the contact point), the breakage of a fuse, or the disturbance of the normal function of the
overload.
• The means for disconnection from a power supply must be incorporated in the xed wiring and
have an air gap contact separation of at least 0.12 in (3 mm) in each active (phase) conductor
• Before terminals are accessed, all supply circuits must be disconnected.
