Problem
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.
• 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.
