Problem Solution
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.
– AR-EH0**, AR-EC0** remote control: Press the Temperature button
repeatedly until the set temperature (minimum: 18°C) is set to
lower than the current temperature.
– AR-KH0** remote control: Press the Temperature button on the
remote control. Then rotate the Wheel 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.
– AR-EH0**, AR-EC0** remote control: Press the Temperature button
repeatedly until the set temperature (maximum: 30°C) is set to
higher than the current temperature.
– AR-KH0** remote control: Press the Temperature button on the
remote control. Then rotate the Wheel until the set temperature
(maximum: 30°C) is set to higher than the current temperature.
The air is not cool
or warm enough.
• 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.
• 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.
