Checks before operation
Check that the wiring is not broken 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.
Ca u tion
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.

OPERATION TIPS
Maintenance
If you plan to idle the unit for a long time, perform the following:
1. Clean the indoor unit and air filter.
2. Select the FAN only mode, let the indoor fan run for a while 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 center
if the unit requires servicing.
Note: Before you clean the air conditioner, be sure to switch the unit off and disconnect the power
supply plug.
When the air conditioner is to be used again:
Use a dry cloth to wipe off the dust accumulated on t h e rear air intake grille, in order to avoid the dust
blowing out from the indoor unit.
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.
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 yet 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 a heat cycle when the outdoor temperature is low
and humidity is high resulting in laower heating efficiency of the air conditioner.
During this condition the air conditioner will stop the 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 out of the indoor unit
A white mist may generate due to a large temperature difference between the air inlet and the air outlet
on the COOL mode in an indoor environment that has a high relative humidity.
A white mist may generate due to moisture generated from the defrosting process when the air conditioner
restarts in the 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 result 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 temper-
ature is changing.
A noise may be heard due to a louver restoring to its original position when the power is first turned on.
23
OPERATION TIPS
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 of the indoor unit.
This is caused by the indoor unit emitting odors extractedfrom building material, furniture,
or smoke.
6.
The air conditioner turns to the FAN only mode from COOL or HEAT (for cooling and heating models
only) mode.
When the indoor temperature reaches the temperature setting on the air conditioner, the compressor stops
automatically, and the air conditioner turns to the FAN only mode. The compressor will start again when the
indoor temperature rises on the COOL mode or falls on the HEAT mode (for cooling and heating models only)
to the set point.
7. Dripping water may accumulate on the surface of the indoor unit when cooling in a high relative
humidity (higher than 80%). Adjust the horizontal louver to the maximum air outlet position and
select the 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 through the indoor unit during the
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 the larger difference between the
indoor and
we suggest you
9.
Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without the 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 the Auto-restart feature, when the power restores, the unit restarts automatically with all the previous
settings preserved by the memory function.
outdoor temperature. If a comfortable temperature can't be achieved by the air conditioner,
use a supplementary heating device.
10. Lightning or a mobile telephone operating nearby may cause the unit to malfunction.
Disconnect the unit's power source and then re-connect the unit to the power again.
Push the ON/OFF button on
the remote controller to restart operation.

TROUBLESHOOTING TIPS
Stop the air conditioner immediately if one of the following faults occur. Disconnect the
power and contact the nearest customer service center.
If the E( 0,1.......) or P( 0, 1 .......) code appears on the LED(LCD)window, disconnect the
power and contact a service technician.
