16 English
Basic Operation
Auto
In Auto mode, the air conditioner will automatically adjust
the temperature and fan speed to maintain your fresh
environment.
• When the indoor temperature is too high, the powerful
cool breeze is generated and when the indoor room
becomes cool enough, the soft breeze is generated.
Cool
The Cool mode is frequently used and you can freely control
the temperature, fan speed, and air flow direction in Cool
mode.
• When you select the Heat mode while the Cool mode is on,
the Cool mode is cancelled.
Dry
The air conditioner in Dry mode acts like a dehumidifier by
removing moisture from the indoor air. The Dry mode will
provide you with fresh air even on a rainy day.
Fan
The Fan mode provides you with a breeze just like a fan to
make fresh environment for you.
Operation Modes
17English
Basic Operation
Heat
In Heat mode, you can warm your room even in fall and
winter.
• The fan may not commence immediately to avoid
generating a cold breeze.
• In Heat mode, defrost operation may be performed to
remove the frost formed on the outdoor unit. (When the
frost is removed by the defrost operation in Heat mode,
steam is generated from the outdoor unit.)
• If you stop operating the air conditioner after heating
operation, the fan will operate for some time to cool the
indoor unit.
• When you select the Cool mode while the Heat mode is on,
the Heat mode is cancelled.
NOTE
• When the outdoor temperature is relatively low and the
humidity is relatively high in Heat mode, the outdoor unit's
heating capacity may decrease due to the frost formed on
the outdoor heat exchanger. The defrost operation removes
the frost formed on the heat exchanger of the outdoor unit
for 5 to 12 minutes. During the defrost operation, the indoor
unit does not generate breeze in order to prevent cold breeze
blowing out.
– The interval between defrost operations can decrease
depending on the amount of the frost formed on the
outdoor unit.
– The interval between defrost operations can also decrease
depending on the humidity level in the air.

Clea ning and Maintenance
Maintaining the Air Conditioner
If the air conditioner will not be used for an extended period of time, dry the air conditioner to
maintain in best conditions.
1. Dry the air conditioner thoroughly by operating in Fan mode for 3 to 4 hours and disconnect
the power plug. There may be internal damage if moisture is left in components.
2. Before using the air conditioner again, dry the inner components of the air conditioner again
by running in Fan mode for 3 to 4 hours. This helps remove odours that may have generated
from dampness.
Periodical checks
Refer to the following chart to maintain the air conditioner properly.

NOTE
• The checks and maintenance operations described above are essential to guarantee the
efficiency of the air conditioner. The frequency of these operations may vary depending on
the characteristics of the area, the amount of dust, etc.
a. The above mentioned operations should be performed more frequently if the area of
installation is very dusty.
b. These operations must always be performed by qualified personnel. For more detailed
information, refer to Installation Manual.

Clea ning and Maintenance
This internal protection operates if an internal fault occurs in the air conditioner.
Type Description
Against cold air
The internal fan will be off against cold air when the heat pump is
heating.
De-ice cycle
The internal fan will be off against cold air when the heat pump is
heating.
Anti-protection of
internal battery
The compressor will be off to protect internal battery when the air
conditioner operates in Cool mode.
Protect compressor
The air conditioner does not start operating immediately to protect
the compressor of the outdoor unit after it has been started.
NOTE
• If the heat pump is operating in Heat mode, the de-ice cycle is actuated to remove frost from
an outdoor unit that may have deposited at low temperatures.
• The internal fan is switched off automatically and restarted only after the de-ice cycle is
completed.
• When the de-ice cycle is operating,it may generate strange sound. It is normal operation for
product safety.

Appendix
If the air conditioner operates abnormally, refer to the following
chart to save time and unnecessary expenses.
Problem Solution
The air
conditioner does
not work at all.
• Check the power status, then operate the air
conditioner again.
• Switch on the circuit breaker, plug in the power
cord, then operate the air conditioner again.
• Make sure that the isolator is turned on.
• Check whether the Timed off function is
running. Operate the air conditioner again by
pressing the Power button.
I cannot change
the temperature.
• Check whether the Fan or Fast mode is running.
In these modes, the air conditioner controls the
set temperature automatically, and you cannot
change the set temperature.
Troubleshooting
34 English
Appendix
Problem Solution
Cool/Warm air
does not come
out the air
conditioner or
performance is
reduced.
• Check whether the set temperature is higher in
the Cool mode or lower in the Heat mode than
the current temperature. Press the Temperature
button on the remote control to change the set
temperature.
• Check whether the air filter is blocked with
dirt. If the air filter is blocked, the cooling and
heating performance may decrease. Remove dirt
regularly.
• Check if the outdoor unit is covered or installed
near the obstacle. Take the cover off and take
the obstacle away. When clearing the obstacle
(e.g. snow or ice), use suitable tools so as to be
careful not to damage the product nor injure
yourself during this process.
• Check whether the air conditioner is running
the defrost function. When ice forms in winter
or the outdoor temperature is too low, the
air conditioner runs the defrost function
automatically. While this function is running, the
indoor fan stops and warm air does not come
out.
• Check whether doors or windows are open. This
may cause poor cooling or heating performance.
Close the doors and windows.
• Check whether the air conditioner is turned
on immediately after the cooling or heating
operation stops. In this case, only the fan runs to
protect the outdoor unit compressor.
• Check whether the pipe length is too long. When
the pipe length exceeds the maximum pipe
length, the cooling and heating performance
may decrease.
Troubleshooting

Problem Solution
I cannot change
the air flow
direction.
• Check whether the good'sleep function is
running. While this function is running, you
cannot control the air flow direction. (But you
can control the air flow direction if this function
is running in the Heat mode.)
I cannot change
the fan speed.
• When the Auto, Dry, or Fast mode is running
or the good'sleep function is running in the
Cool mode, the air conditioner controls the fan
speed automatically and you cannot change
the fan speed.
The remote
control does not
work.
• Replace the batteries in the remote control
with new ones.
• Make sure that nothing is blocking the remote
control sensor.
• Check whether there are strong lighting
apparatus near the air conditioner. Strong light
which comes from fluorescent bulbs or neon
signs may interrupt the electric waves.
The Timed on/off
function does not
work.
• Check whether you pressed the SET button on
the remote control after setting the time.
The indicator
blinks
continuously.
• Press the Power button to turn off the air
conditioner or disconnect the power plug. If the
indicator is still blinking, contact the service
centre.
36 English
Appendix
Problem Solution
Odours permeate
in the room
during operation.
• Check whether the air conditioner is running
in a smoky area. Ventilate the room or operate
the air conditioner in the Fan mode for 3 to 4
hours. (There are no components used in the
air conditioner that emit a strong odour.)
• Check whether the drains are clean. Clean them
regularly.
An error is
indicated.
• If the indoor unit indicator blinks, contact the
nearest service centre. Be sure to pass the
error code to the service centre.
Noise is
generated.
• When refrigerant flow changes, noise may be
generated, depending on the status of the air
conditioner. This is a normal operation.
'Excessive Noise
is Generated'
and ‘Reduced
Performance'
• If excessive/irregular noise is generated in
conjunction with reduced product performance,
please refer to your service engineer to ensure
the product is operating correctly.
Smoke is
generated from
the outdoor unit.
• If may not be a fire but it can be a steam
generated from the outdoor heat exchanger
while the defrost function is running in the
Heat mode in winter.
Water drops
from the pipe
connections of
the outdoor unit.
• Condensation may develop when the ambient
temperature changes excessively. This is a
normal operation.
