Troubleshooting
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.
Cool or warm air
does not come
out of the air
conditioner.
• 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 whether the outdoor unit is covered
or installed near obstacles. Remove the
coverings and obstacles.

Cleaning and Maintenance
Problem Solution
Cool or warm air
does not come
out of the air
conditioner.
• 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.
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.

Cleaning and Maintenance
Problem Solution
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.
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.

Problem Solution
Noise is
generated.
• When refrigerant flow changes, noise may
be generated, depending on the status
of the air conditioner. This is a normal
operation.
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.
To perform its antimicrobial function this product has been treated
