Operating Conditions
Use the system under the following temperatures for safe and eective operation. If the air
conditioner is used under dierent conditions, it may malfunction or become less ecient.
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 indoor heat exchanger
is in one of the following three situations and
the set temperature has not been reached.
A) When heating has just started.
B) During defrosting.
C) Low temperature heating.
•The indoor or outdoor fan stop running when
defrosting (Cooling and heating models only).
Defrosting (Cooling and heating models only)
•Frost may be generated on the outdoor unit
during a heat cycle when outdoor temperature
is low and humidity is high resulting in lower
heating eciency 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 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 using the same
settings.
White mist emerging from the indoor unit
•A white mist may be generated due to a large
temperature dierence between air inlet and
air outlet on 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 operation
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 sound 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 tempera
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 is happens when the air conditioner has not
been used for a long time or during its rst use.
Smell emitting from the indoor unit.
This is caused by the indoor unit giving o smells
permeated from building materials, furniture,or
smoke.
NOTE: For multi-split type air conditioners, one outdoor unit can be matched to dierent types of
indoor units. All of the pictures in this manual are for demonstration purposes only. Your air
conditioner may be slightly dierent, if similar in shape. The following pages introduce several kinds
of indoor units that can be matched with the outdoor units.

Unit Parts
And Major
Functions
Energy Saving Tips
• DO NOT
set the unit to excessive temperature levels.
• While cooling, close the curtains to avoid direct sunlight.
• Doors and windows should be kept closed to keep cool or warm air in the room.
•
DO NOT
place objects near the air inlet and outlet of the unit. This will reduce the efficiency of the unit.
• 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. A dirty filter can reduce cooling or heating efficiency.
• 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 setting, the compressor will stop
automatically, and the air conditioner turns to
FAN only mode. The compressor will start again
when the indoor temperature rises on COOL
mode or falls on 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 (dened 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
larger dierence between indoor and outdoor
temperature. If a comfortable temperature
cannot be achieved with 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 re-connect the unit with the power source
again. Push the ON/OFF button on the remote
controller to restart operations.
Closing curtains during heating also
helps keep the heat in Doors and windows should be kept
closed

Manual Operations
And Maintenance
Manual Operations And Maintenance 3
Operation mode selection
Maintenance
While two or more indoor units are
simultaneously operating, make sure the modes
do not conict with each other. The heat mode
claims precedence over all other modes. If the
unit intially started to operate in HEAT mode, the
other units can operate in HEAT mode only. For
example: If the unit intially started operates under
COOL (or FAN) mode, the other units can operate
under any mode except HEAT. If one of the unit
selects HEAT mode, the other operating units will
stop operation and diplay ”--” (for units with
display window only) 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) wil light up,
or the operation indication light will ash rapidly,
and the timer indication light will turn o ( for
the oor and standing type).
If you plan to leave the unit idle for a long time,
perform the following tasks:
1. Clean the indoor unit and 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 components of the outdoor unit
periodically. Contact a local dealer or a
customer service centre 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 in
order to avoid the dust being dispersed 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 0°C (32°F), it is strongly recommended
that you to keep the machine plugged in so
as to guarantee smooth operation.
Optimal operation
To achieve optimal performance, please note the
following:
•Adjust the direction of the air flow so that it is
notblowing 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
controller to select a time you want to start your
air conditioner.
•Do not place any object near the air inlet or air
outlet, as the efficiency of the air conditioner
may be reduced and the air conditioner may
stop running.
•Clean the air filter periodically, otherwise
cooling or heating performance may be
reduced.
•Do not operate unit with horizontal louvre in
closed position.
NOTE: Before you clean the air conditioner, be
sure to switch o the unit and disconnect the
power supply plug.

Troubleshooting
CAUTIONS
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 a malfunction and in most situations will not require repairs.
Problem Possible Causes
Unit does not
turn on when
pressing ON/
OFF button
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 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 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 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 white mist In humid regions, a large temperature dierence between the room’s air and
the conditioned air can cause white mist.
Both the indoor
and outdoor units
emit white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
Troubleshooting 4
Page 12
Troubleshooting
Problem Possible Causes
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.
The fan of the
outdoor unit
does not operate During operation, the fan speed is controlled to optimize product operation.
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 running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor
unit and outdoor
unit 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 dierent sounds based on its current operating mode.
