Features
Protection of the air conditioner
Compressor protection
• The compressor cannot restart for 3 minutes
after it stops.
Anti-cold air (cooling and heating models
only)
• The unit is designed not to blow cold air on
HEAT mode, when the set temperature has not
been reached and the indoor heat exchanger is
in one of the following three situations:
A) Heating has just started
B) The unit is defrosting
C) The unit is heated at a low temperature
• The indoor or outdoor fan stops running when
defrosting (cooling and heating models only).
• Frost may be generated on the outdoor unit
during a heat cycle when the outdoor
temperature is low and the humidity is high,
resulting in lower
heating eciency in the air conditioner.
• Under these conditions, the air conditioner will
stop heating operations and start defrosting
automatically.
• The time to defrost may vary from 4 to 10
minutes, depending on the outdoor temperature
and the amount of frost buildup on the
outdoor unit.
Auto-restart (some models)
In case of power failure, the system will
immediately stop. When power returns, the
operation light on the indoor unit will flash. To
restart the unit, press the ON/OFF button on the
remote control. If the system has an auto-restart
function, the unit will restart with the same
settings.
White mist emerging from the indoor unit
• A white mist may be generated due to a large
temperature dierence between air inlet and
air outlet in COOL mode in places with high
relative humidity.
• A white mist may be generated due to moisture
created in the defrosting process when the air
conditioner restarts in HEAT mode after
defrosting.
Noise coming from the air conditioner
• You may hear a low hissing sound when the
compressor is running or has just stopped
running. This is the sound of the
refrigerant owing or coming to a stop.
• You may also hear a low "squeaking" sound
when the compressor is running or has just
stopped running. This is caused by
heat expansion and cold contraction of the
plastic parts in the unit when the temperature
is changing.
• A noise may be heard due to the louver
restoring itself to its original position when
power is rst turned on.
Dust blowing out from the indoor unit.
This happens when the air conditioner has not
been used for a long time or during its rst use.
Smell coming from the indoor unit.
The indoor unit gives o smells drawn from
building materials, furniture, or smoke.
NOTE: For multi-split type air conditioners, one outdoor unit can be matched to dierent types of
indoor units. All of the pictures in this manual are for demonstration purposes only. Your air
conditioner may be slightly dierent, if similar in shape. The following pages introduce several kinds
of indoor units that can be matched with the outdoor units.

Energy-Saving Tips
• DO NOT set the unit to excessive temperature levels.
• When the unit is cooling, close curtains to avoid exposure to direct sunlight.
• Keep doors and windows closed to keep cool or warm air in the room.
•
DO NOT place objects near the unit's air inlet or outlet.
• Set a timer and use the built-in SLEEP/ECONOMY mode if applicable.
• If you don’t plan to use the unit for a long time, remove the batteries from the remote control.
• Clean the air filter every two weeks.
• Adjust louvers properly and avoid direct airflow.
The air conditioner turns to FAN ONLY
mode from COOL or HEAT (for cooling and
heating models only) mode.
When the indoor temperature reaches the set
temperature, the compressor will stop
automatically and the air conditioner will turn to
FAN ONLY mode. The compressor will start again
when the indoor temperature rises in COOL
mode or falls in HEAT mode to the set point.
Droplets of water may form on the surface of
the indoor unit when cooling occurs in relatively
high humidity (dened as higher than 80%).
Adjust the horizontal louver to the maximum air
outlet position and select HIGH fan speed.
Heating mode (for cooling and heating
models only)
The air conditioner draws in heat from the
outdoor unit and releases it via the indoor unit
during heating. When the outdoor temperature
falls, heat drawn in by the air conditioner
decreases accordingly. At the same time, heat
loading of the air conditioner increases due to the
larger dierence between the indoor and outdoor
temperatures. If a comfortable temperature
cannot be achieved by the air conditioner
alone, it is recommended that you use a
supplementary heating device.
Lightning or a car wireless telephone operating
nearby may cause the unit to malfunction.
Disconnect the unit from its power source and
then reconnect the unit with the power source.
Push the ON/OFF button on the remote
control to restart operation.
Closing curtains during heating
helps keep the heat in.
Doors and windows should be kept
closed.

Manual Operation and Maintenance 3
Operation Mode Selection
Maintenance
When two or more indoor units are
operating simultaneously, make sure the modes
do not conict with each other. HEAT mode
claims precedence over all other modes. If the
unit initially operated in HEAT mode, the
other units can operate in HEAT mode only. For
example: If the unit initially operated in COOL
(or FAN) mode, the other units can operate
under any mode except HEAT. If one of the units
selects HEAT mode, the other operating units will
stop operation and diplay ”--” (for units with a
display window) or the auto and operation
indication light will ash rapidly, the defrost
indication light will turn o, and the timer
indication light will remain on (for units without
a display window). Alternatively, the defrost and
alarm indication light (if applicable) will light up,
or the operation indication light will ash rapidly,
and the timer indication light will turn o (for
the oor and standing types).
If you plan to leave the unit idle for a long time,
perform the following tasks:
1. Clean the indoor unit and the air lter.
2. Select FAN ONLY mode and let the indoor fan
run for a time to dry the inside of the unit.
3. Disconnect the power supply and remove the
battery from the remote control.
4. Check the components of the outdoor unit
periodically. Contact a local dealer or a
customer service center if the unit requires
servicing.
When the air conditioner is to be used
again:
• Use a dry cloth to wipe o the dust
accumulated on the rear air intake grille to avoid
the dispersion of the dust from the indoor unit.
• Check that the wiring is not broken o or
disconnected.
• Check that the air lter is installed.
• Check if the air outlet or inlet is blocked after
the air conditioner has not been used for a long
time.
Suggestion:
For units that feature an electric heater,
when the outside ambient temperature is
below 32° F (0° C), it is strongly recommended
that you keep the machine plugged in
to guarantee smooth operation.
Optimal Operation
To achieve optimal performance, please note the
following:
• Adjust the direction of the airow so that it
does not blow directly on people.
• Adjust the temperature to achieve the highest
possible level of comfort. Do not adjust the
unit to excessive temperature levels.
• Close doors and windows in COOL mode or
HEAT mode.
• Use the TIMER ON button on the remote
control to select a time for the air conditioner
to start.
• Do not place any object near the air inlet or outlet,
as the eciency of the air conditioner
may be reduced and it may stop running.
• Clean the air lter periodically. Otherwise,
cooling or heating performance may be
reduced.
• Do not operate the unit with the horizontal
louver in the closed position.
NOTE: Before you clean the air conditioner, be
sure to switch o the unit and disconnect the
power supply plug.

Troubleshooting
CAUTION
If one of the following conditions occurs, switch o the power supply immediately and contact
your dealer for further assistance.
• The operation light continues to flash rapidly after the unit has been restarted
• The remote control buttons do not work
• The unit continually trips fuses or circuit breakers
• A foreign object or water enters the air conditioner
• Other abnormal situations
Common Problems
The following symptoms are not malfunctions and in most situations will not require repairs:
Problem Possible Causes
The unit does not
turn on when the
ON/OFF button
is pressed
The unit has a 3-minute protection feature that prevents it from
overloading. The unit cannot be restarted within 3 minutes of being
turned o.
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 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 to
defrost the unit.
The unit changes
from COOL mode
to FAN mode
The unit changes its setting to prevent frost from forming on the unit. Once
the temperature increases, the unit will start operating again.
The set temperature has been reached, at which point the unit turns o the
compressor. The unit will resume operating when the temperature fluctuates
again.
The indoor unit
emits a white mist
In humid regions, a large temperature dierence between the room’s air and
the conditioned air can cause a white mist.
Both the indoor
and outdoor units
emit a white mist
When the unit restarts in HEAT mode after defrosting, a white mist may be
emitted due to moisture generated from the defrosting process.
The indoor unit
makes noises
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 the unit is run in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor
and outdoor units
make noises
A low hissing sound may occur during operation. This is normal and is caused
by refrigerant gas flowing through both the indoor and outdoor units.
A low hissing sound may be heard 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.
The outdoor unit
makes noises The unit will make dierent sounds based on its current operating mode.
