Common Issues
The following problems are not a malfunction and in most situations will not require repairs.
Issue
Unit does not turn on when pressing ON/OFF button
The unit changes from COOL/HEAT mode to FAN mode
The indoor unit emits white mist Both the indoor and outdoor units emit white
mist
The indoor unit makes noises
Both the indoor unit and outdoor unit make noises
Possible Causes
The Unit has a 3-minute protection feature that prevents the unit from
overloading. The unit cannot be restarted within three minutes of being turned
off. Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-
heating/ Defrost) indicators are lit up, the outdoor temperature is too cold
and the unit’s anti-cold wind is activated in order to defrost the unit. In
Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor
temperature is too cold and the unit’s anti-freeze protection is activated in
order to defrost the unit.
The unit may change its setting to prevent frost from forming on the unit.
Once the temperature increases, the unit will start operating in the
previously selected mode again. The set temperature has been reached, at which
point the unit turns off the compressor. The unit will continue operating when
the temperature fluctuates again.
In humid regions, a large temperature difference between the room’s air and
the conditioned air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
A rushing air sound may occur when the louver resets its position. A squeaking
sound is heard when the system is OFF or in COOL mode. The noise is also heard
when the drain pump (optional) is in operation. A squeaking sound may occur
after running the unit in HEAT mode due to expansion and contraction of the
unit’s plastic parts. Low hissing sound during operation: This is normal and
is caused by refrigerant gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is
defrosting: This noise is normal and is caused by the refrigerant gas stopping
or changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts
caused by temperature changes during operation can cause squeaking noises.
09
Issue
Possible Causes
The outdoor unit makes noises
The unit will make different sounds based on its current operating mode.
Dust is emitted from either the indoor or outdoor unit
The unit may accumulate dust during extended periods of non-use, which will be emitted when the unit is turned on. This can be mitigated by covering the unit during long periods of inactivity.
The unit emits a bad odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become moldy and should be cleaned. Contact a
professional technician directly to replace.

Connection Instructions–Refrigerant Piping
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 condensation.
Step 1: Cut pipes
When preparing refrigerant pipes, take extra care to cut and flare them
properly. This will ensure efficient operation and minimize the need for
future maintenance.
Measure the distance between the · indoor and outdoor units.
Using a pipe cutter, cut the pipe a · little longer than the measured
distance. Make sure that the pipe is cut at a · perfect 90° angle.
Step 2: Remove burrs
Burrs can affect the air-tight seal of refrigerant piping connection. They
must be completely removed.
· Hold the pipe at a downward angle to prevent burrs from falling into the
pipe.
· Using a reamer or deburring tool, remove all burrs from the cut section of
the pipe.

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
Step 3: Flare pipe ends
Proper flaring is essential to achieve an airtight seal.
· After removing burrs from cut pipe, seal the ends with PVC tape to prevent
foreign materials from entering the pipe.
· Sheath the pipe with insulating material. · Place flare 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 flaring.

· Remove the flaring tool and flare form, then inspect the end of the pipe for
cracks and even flaring.
Step 4: Connect pipes
Connect the copper pipes to the indoor unit first, then connect it to the
outdoor unit. You should first connect the low-pressure pipe, then the
highpressure pipe.
· When connecting the flare nuts, apply a thin coat of refrigeration oil to
the flared ends of the pipes.
· Align the center of the two pipes that you will connect.
· Tighten the flare nut snugly by hand. · Using a wrench, grip the nut on the
unit tubing. · While firmly gripping the nut, use a torque
wrench to tighten the flare nut according to the torque values in above table.
NOTICE
Use both a spanner and a torque wrench when connecting or disconnecting pipes
to/from the unit.

WIRING PRECAUTIONS
WARNING
BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE WARNINGS.
° All wiring must comply with local and national electrical codes, regulations
and must be installed by a licensed electrician.
° All electrical connections must be made according to the Electrical
Connection Diagramlocated on the panels of the indoor and outdoor units.
° If there is a serious safety issue with the power supply, stop work
immediately. Explain your reasoning to the client, and refuse to install the
unit until the safety issue is properly resolved.
° Power voltage should be within 90-110% of rated voltage. Insufficient power
supply can cause malfunction, electrical shock, or fire.
° Installation of an external surge suppressor at the outdoor disconnect is
recommended.
° If connecting power to fixed wiring, a switch or circult breaker that
disconnects all poles and has a contact separation of at least 1/8in (3mm)
must be incorporated in the fixed wiring. The qualified technician must use an
approved circuit breaker or switch.
° Only connect the unit to an individual branch circuit. Do not connect
another appliance to that outlet.
° Make sure to properly ground the air conditioner. ° Every wire must be
firmly connected. Loose
wiring can cause the terminal to overheat, resulting in product malfunction
and possible fire.
° Do not let wires touch or rest against refrigerant tubing, the compressor,
or any moving parts within the unit.
° If the unit has an auxiliary electric heater, it must be installed at least
1 meter (40in) away from any combustible materials.
° To avoid getting an electric shock, never touch the electrical components
soon after the power supply has been turned off. After turning off the power,
always wait 10 minutes or more before you touch the electrical components.
° Make sure that you do not cross your electrical wiring with your signal
wiring. This may cause distortion, interference or
° possibly damage to circuit boards. ° No other equipment should be connected
to the same power circuit. ° Connect the outdoor wires before
connecting the indoor wires.
WARNING
BEFORE PERFORMING ANY ELECTRICAL OR WIRING WORK, TURN OFF THE MAIN POWER TO
THE SYSTEM.

AIR EVACUATION
NOTE
When opening valve stems, turn the hexagonal wrench until it hits against the
stopper. Do not try to force the valve to open further.
Preparations and precautions
Air and foreign matter in the refrigerant circuit can cause abnormal rises in
pressure, which can damage the air conditioner, reduce its efficiency, and
cause injury. Use a vacuum pump and manifold gauge to evacuate the refrigerant
circuit, removing any non-condensable gas and moisture from the system.
Evacuation should be performed upon initial installation and when unit is
relocated.
6. Close the Low Pressure side of the manifold gauge, and turn off the vacuum
pump.
7. Wait for 5 minutes, then check that there has been no change in system
pressure.
8. If there is a change in system pressure, refer to Gas Leak Check section
for information on how to check for leaks. If there is no change in system
pressure, unscrew the cap from the packed valve (high pressure valve).
9. Insert hexagonal wrench into the packed valve (high pressure valve) and
open the valve by turning the wrench in a 1/4 counterclockwise turn. Listen
for gas to exit the system, then close the valve after 5 seconds.
10.Watch the Pressure Gauge for one minute to make sure that there is no
change in pressure. The Pressure Gauge should read slightly higher than
atmospheric pressure.
11. Remove the charge hose from the service port.
Evacuation Instructions
Flare nut
1. Connect the charge hose of the manifold gauge
to service port on the outdoor unit’s low
pressure valve.
2. Connect another charge hose from the manifold
gauge to the vacuum pump.
3. Open the Low Pressure side of the manifold
gauge. Keep the High Pressure side closed.

NOTE ON ADDING REFRIGERANT
CAUTION
DO NOT mix refrigerant types.
Some systems require additional charging depending on pipe lengths. The
standard pipe length varies according to local regulations. For example, in
North America, the standard pipe length is 7.5m (25′). In other areas, the
standard pipe length is 5m (16`). The refrigerant should be charged from the
service port on the outdoor unit’s low pressure valve. The additional
refrigerant to be charged can be calculated using the following formula:
R32 :
(Total pipe length standard pipe length)x 12g(0.13oZ)/m(ft)
(Total pipe length standard pipe length)x 24g(0.26oZ)/m(ft)
(Total pipe length standard pipe length)x 40g(0.42oZ)/m(ft)
CAUTION DO NOT mix refrigerant types.
Only for Australia models : · This unit contains factory charged refrigerant
covering 20m of refrigerant piping and additional
refrigerant charge on the installation site is not required for an
installation with up to 20m refrigerant piping. When refrigerant piping
exceeds 20m, additionally charge an amount calculated from the pipe length and
the above table for the portion in excess of 20m. · If an existing pipe system
is used, a required refrigerant charge volume will vary depending on the
liquid pipe size. Formula to calculate the volume of additional refrigerant
required Additional charge volume (kg) = { Main length (m) Factory charged
volume 20(m) } × 0.03(kg/m) · Make sure to remove the additional refrigerant
amount according to the nameplate rated charge (under 5m refrigerant piping )
under market or government verification testing.
