Troubleshooting
Refer to the following chart if the air conditioner operates abnormally. This may save time and
unnecessary expense.
Problem Solution
The air conditioner
does not operate
immediately after it
has been restarted.
• Because of the protective mechanism, the appliance does not start
operating immediately to keep the unit from overloading. The air
conditioner will start in 3 minutes.
The air conditioner
does not operate
at all.
• Check if the power plug is properly connected.
• Check whether the auxiliary power switch (MCCB, ELB) is turned on.
• If the auxiliary power switch (MCCB, ELB) is turned off, the air
conditioner does not work although you press the (Power) button.
• When you clean the air conditioner or do not use it for an extended
period of time, turn off the auxiliary power switch (MCCB, ELB).
• After the air conditioner is not used for an extended period of time, be
sure to turn on the auxiliary power switch (MCCB, ELB) 6 hours before
starting operation.
NOTE
• The auxiliary power switch (MCCB, ELB) is sold separately.
• Make sure that auxiliary power switch (MCCB, ELB) is installed in
the distribution box inside the building.
• If the air conditioner is turned off by the Timed off function, turn on the
air conditioner again by pressing the (Power) button.
The temperature
does not change.
• Check whether the Fan mode is running. In the Fan mode, the air
conditioner controls the set temperature automatically, and you cannot
change the set temperature.
Warm air does not
come out of the air
conditioner.
• Check whether the outdoor unit is designed for cooling only. In this case,
warm air does not come out although you select the Heat mode.
• Check whether the remote control is designed only for cooling only. Use
a remote control that supports both cooling and heating.
The fan speed does
not change.
• Check whether the Auto or Dry mode is running. In these modes, the
air conditioner controls the fan speed automatically, and you cannot
change the fan speed.
The wireless
remote control
does not operate.
• Check whether the batteries are discharged. Replace the batteries with
new ones.
• Make sure that nothing is blocking the remote control sensor.
• Check whether any strong lighting sources are near the air conditioner.
Strong light which comes from fluorescent bulbs or neon signs may
interfere with the remote control.

Problem Solution
The wired remote
control does not
operate.
• Check whether the indicator is displayed at the bottom right of the
remote control display. In this case, turn off both the air conditioner and
the auxiliary power switch, and then contact a service centre.
The air conditioner
is not turned on or
off immediately
with the wired
remote control.
• Check whether the wired remote control is set for group control. In this
case, the air conditioners connected to the wired remote control are
turned on or off sequentially. This operation takes up to 32 seconds.
The Timed on/off
function does not
operate.
• Check whether you pressed the (SET) button on the remote control
after setting the on/off time. Set the on/off time.
The indoor unit
display blinks
continuously.
• Turn on the air conditioner again by pressing the (Power) button.
• Turn off and then turn on the auxiliary power switch, and then turn on
the conditioner.
• If the indoor unit display is still blinking, contact a service centre.
I want to get cooler
air.
• Operate the air conditioner with a electric fan to save energy and
enhance the cooling efficiency.
The air is not cool or
warm enough.
• In the Cool mode, cool air does not come out if the set temperature is
higher than the current temperature.
– Remote control: Press the Temperature button repeatedly until the
set temperature (minimum: 18°C) is set to lower than the current
temperature.
• In the Heat mode, warm air does not come out if the set temperature is
lower than the current temperature.
– Remote control: Press the Temperature button repeatedly until the
set temperature (maximum: 30°C) is set to higher than the current
temperature.
• Both cooling and heating do not operate in the Fan mode. Select the
Cool, Heat, Auto, or Dry mode.
• Check whether the air filter is blocked with dirt. A dusty filter may
decrease the cooling and heating efficiencies. Clean the air filter
frequently.
• If a cover is on the outdoor unit or any obstacle is present near the
outdoor unit, remove them.
• Install the outdoor unit in a well-ventilated place. Avoiding places
exposed to direct sunlight or close to a heating appliance.
• Place a sunscreen over the outdoor unit to protect it from direct
sunlight.
• If the indoor unit is installed in a place exposed to direct sunlight, pull
the curtains on the windows.

Cleaning and Maintenance
Problem Solution
The air is not cool or
warm enough.
• Close the windows and doors to maximize the cooling and heating
efficiencies.
• If the Cool mode is stopped and then started immediately, cool air comes
out after about 3 minutes to protect the compressor of the outdoor unit.
• When the Heat mode is started, warm air does not come out
immediately to prevent cool air from coming out at the beginning.
• If the refrigerant pipe is too long, the cooling and heating efficiencies
may be decreased. Avoid exceeding the maximum pipe length.
The air conditioner
makes strange
noises.
• In certain conditions (especially, when the outdoor temperature is
lower than 20°C), a hissing, rumbling, or splashing sound may be heard
while the refrigerant is circulating through the air conditioner. This is a
normal operation.
• When you press the (Power) button on the remote control, noise
may be heard from the drain pump inside the air conditioner. This noise
is a normal sound.
Unpleasant odours
permeate the room.
• If the air conditioner is running in a smoky area or if there is a smell
entering from outside, ventilate the room properly.
• If both indoor temperature and indoor humidity are high, operate the air
conditioner in the Clean or Fan mode for 1 to 2 hours.
• If the air conditioner has not been operated for an extended period
of time, clean the indoor unit and then operate the air conditioner in
the Fan mode for 3 to 4 hours to dry the inside of the indoor unit for
removal of unpleasant odours.
• If the air filter blocked with dirt, clean the air filter.
Steam is produced
on the indoor unit.
• In winter, if the indoor humidity is high, steam may be produced around
the air outlet while the defrost function is running. This is a normal
operation.
The outdoor unit
fan continues to
operate when the
air conditioner is
turned off.
• W hen the air conditioner is turned off, the outdoor unit fan may
continue to operate to reduce noise of the refrigerant gas. This is a
normal operation.
Water drops
from the piping
connections of the
outdoor unit.
• Condensation may develop due to the difference in temperature. This is
a normal condition.
Steam is produced
on the outdoor unit.
• In winter, when the air conditioner runs in the Heat mode, the frost on
the heat exchanger melts and steam may be produced. This is a normal
operation, neither product malfunction nor a fire.
