HOW THE AIR CONDITIONER WORKS
AUTOMATIC OPERATION
When you set the air conditioner in
AUTO mode, it will automatically
select cooling, heating (cooling/
heating models only), or fan-only
operation depending on what tem-
perature you have selected and the
room temperature.
The air conditioner will control
room temperature automatically
around the temperature point set
by you.
If the AUTO mode is uncomfortable,
you can select desired conditions
manually.
ECONOMIC (SLEEP) OPERATION
When you push the ECONO (SLEEP)
button on the remote control
during cooling, heating, or AUTO
operation, the air conditioner will
automatically increase (cooling) or
decrease (heating) one (1) per hour.
The set temperature will be steady
two (2) hours later. The fan speed
will be automatically controlled.
This feature can maintain the most
comfortable temperature and save
more energy for you.
•
•
•
•
DRYING OPERATION
The dry mode will automatically select the DRY operation based on the dif-
ference between the set temperature and the actual room temperature.
The temperature is regulated while dehumidifying by repeatedly turning on
and off the cooling operation or fan only. The fan speed indicator will display
AUTO and low speed will be used.
•

OPERATION TIPS
The following events may occur during normal operation.
1. PROTECTION OF THE AIR CONDITIONER
COMPRESSOR PROTECTION
The compressor can’t 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 tem-
perature has not been reached.
A) When heating has just starting
B) 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 heat cycle when out-
door temperature is low and humidity is high resulting in lower heating
efficiency of the air conditioner.
During this condition air conditioner will stop heating operation and start
defrosting automatically.
The time to defrost may vary from 4 to 10 minutes according to the out-
door temperature and the amount of frost buildup on the outdoor unit.
2. A WHITE MIST COMING OUT FROM THE INDOOR UNIT
A white mist may generate due to a large temperature difference between
air inlet and air outlet on COOL mode in an indoor environment that has
a high relative humidity.
A white mist may generate due to moisture generated from defrosting
process when the air conditioner restarts in HEAT mode operation after
defrosting.
3. LOW NOISE OF 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 flowing
or coming to a stop.
You can also hear a low “squeak” 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 chang-
ing.
A noise may be heard due to louver restoring to its original position when
power is first turned on.

4. DUST IS BLOWN OUT FROM THE INDOOR UNIT
This is a normal condition when the air conditioner has not been used for a
long time or during first use of the unit.
5. A PECULIAR SMELL COMES OUT FROM THE INDOOR UNIT
This is caused by the indoor unit giving off smells permeated from building
material, furniture, or smoke.
6. THE AIR CONDITIONER TURNS TO FAN-ONLY MODE FROM COOL OR HEAT MODE
(FOR COOLING/HEATING MODELS ONLY)
When indoor temperature reaches the temperature setting on air conditioner,
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 (for cooling/heating
models only).
7. DRIPPING WATER
Dripping water may generate on the surface of the indoor unit when cooling
in a relatively high humidity (relative humidity higher than 80%). Adjust the
horizontal louver to the maximum air outlet position and select HIGH fan
speed.
8. HEATING MODE (FOR COOLING/HEATING MODELS ONLY)
The air conditioner draws in heat from the outdoor unit and releases it via
the indoor unit during HEAT operation. 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 a larger difference between
indoor and outdoor temperatures. If a comfortable temperature can’t be
achieved by the air conditioner, we suggest you use a supplementary heating
device.
9. AUTO-RESTART FUNCTION
Power failure during operation will stop the unit completely. For units without
auto-restart, the OPERATION indicator on the indoor unit will flash when the
power is restored. To restart the unit, push the ON/OFF button on the remote
control. For units with auto-restart, the unit restarts automatically with all
the previous settings preserved by the memory function when the power is
restored.
10. LIGHTNING OR OTHER ELECTRICAL INTERFERENCE
Lightning or a car wireless telephone operating nearby may cause the unit to
malfunction. Disconnect the unit from the power and then re-connect the unit.
Push the ON/OFF button on the remote control to restart the unit.
