HOW THE AIR CONDITIONER WORKS
AUTO 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
temperature you have selected and the room temperature.
The air conditioner will control room temperature
automatically round the temperature point set by you.
If the AUTO mode is uncomfortable, you can select
desired conditions manually.
SLEEP operation
When you push SLEEP button on remote controller during
cooling, heating(cooling only type without), or AUTO operation ,
the air conditioner will automatically increase (cooling) or
decrease (heating) 1 per hour for the first 2 hours, then
hold steady for the next 5 hours, after that it will switch off.
This characteristic maintains both enery saving and comfort
in night operation.
DRYING operation
The fan speed will be automatically controlled under dry
operation.
During the dry operation, if the room temperature is lower
O
than 10 C, the compressor stops operation and restarts
O
until the room temperature is above 12 C.

Maintenance
Checks before operation
If you plan to idle the unit for a long time, perform the
following:
(1) Operate the fan for about half a day to dry the
inside of the unit.
(2) Stop the air conditioner and disconnect power.
Remove the batteries from the remote controller.
(3) The outdoor unit requires periodic maintenance
and cleaning. Do not attempt to do this yourself.
Contact your dealer or servicer.
Check that the wiring is not broken off or disconnected.
Check that the air filter is installed.
Check if the air outlet or inlet is blocked after the
air conditioner has not been used for a long time.
CAUTIONS
Do not touch the metal parts of the unit when
removing the filter. Injuries can occur when
handling sharp metal edges.
Do not use water to clean inside the air conditioner.
Exposure to water can destroy the insulation,
leading to possible electric shock.
When cleaning the unit, first make sure that the
power and circuit breaker are turned off.
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 temperature 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 outdoor 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 outdoor 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 changing.
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, from furniture,
or smoke.
10
6. The air conditioner turns to FAN only mode from COOL or HEAT (For cooling and
heating models only) mode.
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 (For cooling and heating
models only) to the set point.
11
7. Dripping water may generate on the surface of the indoor unit when cooling in a high
relatively 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 and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the indoor unit
during heating 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 larger difference between indoor and outdoor temperature. 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 the unit without Auto-restart feature, when the power restores, the OPERATION indicator
on the indoor unit starts flashing. To restart the operation, push the ON/OFF button on the
remote controller. For the unit with Auto-restart feature, when the power restores, the unit
restarts automatically with all the previous settings preserved by the memory function.
10. Lightning or a car wireless telephone operating nearby may cause the unit to malfunction.
Disconnect the unit with power and then re-connect the unit with power again. Push the
ON/OFF button on the remote controller to restart operation.
