Problem Solution
The air conditioner stops
working.
• Make sure the unit is receiving power.
• Check the circuit breaker. If it is flipped off, flip it on again and restart
the unit. If the problem persists, contact your service provider.
• The Timed off function may have turned off the unit. Turn on the unit
again.
Cannot change the

Improper airflow
temperature.
• Check the set temperature. In Cool mode, cooling occurs only when the
set temperature is lower than the current temperature. In Heat mode,
heating occurs only when the set temperature is higher than the current
temperature.
• Use the button on the remote control to change the set
temperature.
• Check if the air filter is blocked with dirt or debris. If the air filter is
blocked, the cooling and heating performance may decrease. Clean the
air filter regularly (page 43).
• Check if the outdoor unit is covered or is installed near obstacles.
Remove the coverings and obstacles.
• Check if the Defrost function is on (page 27). During defrost, the fan
stops and warm air does not come out.
• Check if doors or windows are open. This may cause poor circulation or
performance. Close all doors and windows.
• Check if the pipe length between the units exceeds the maximum pipe
length (see “Typical installation” in the Installation manual). If so, the
cooling and heating performance may decrease.
Cannot change the airflow
direction.
• Check if the Good Sleep function is on in Cool mode. If so, you cannot
control the airflow direction.
Cannot change the fan speed.
• Check if the unit is in AI Auto, or Dry mode or the Good Sleep function is
on in Cool mode. In these conditions, you cannot control the fan speed;
the unit automatically controls the fan speed.
The remote control does not
work.
• Charge the remote control, using the USB port (type C) on the bottom of
the remote control.
• Make sure the remote control can send an unobstructed signal to the
unit.
• Keep bright lights away from the unit. Light from fluorescent bulbs or
neon signs may interrupt the signal from the remote control.
The Timed on/off function
does not work.
• Make sure to press the button on the remote control when
setting the timer.
If the air conditioner is not operating normally, refer to the troubleshooting guide below.

• If the indicator light on the indoor unit display continues blinking,
contact your service provider.
Odors are coming from the
unit during regular operation.
• If the unit is operating in a smoky area, ventilate the room or operate the
unit in Fan mode for 3 to 4 hours. There are no components in the unit
that produce a strong odor.
• Check if the drain pipes are clean. Clean them regularly.
The indoor unit display shows
an error message.
• If the indoor unit indicator blinks, write down the error code. Contact
your service provider and provide them with the error code.
The unit is generating noise.
• It is normal for the unit to generate some noise while operating.
If the pipe length between the units is less than 3 m and no coil was
used (see “Typical installation” in the Installation manual), additional
noise may be transmitted from the outdoor unit to the indoor unit via
the piping.
Smoke is coming from the
outdoor unit.
• In winter, most likely this is steam coming from the outdoor heat
exchanger while the Defrost function is on.
Water drips from the pipe
connections on the outdoor
unit.
• Condensation may develop when the ambient temperature or humidity
changes significantly. This is normal.
Condensation forms on the
surface of the indoor unit.
• If the humidity is higher in the room in Cool mode, or the difference
between the desired temperature and indoor temperature is great,
condensation may form on the surface of the indoor unit.
