• Check whether
display. Make sure that the power and communication cables
are connected correctly between the indoor and outdoor units,
and then restart the air conditioner. If the error is still displayed,
contact a service centre.

• In the Cool mode, air does not come out if the set temperature is
higher than the current temperature.
• Cooling does not operate in the Fan mode. Select the Cool, Auto, or
Dry mode.
• Check whether the air filter is blocked with dirt. A dusty filter may
decrease the cooling 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. Avoid 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 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.
• If the refrigerant pipe is too long, the cooling efficiencies may be
decreased. Avoid exceeding the maximum pipe length.
• 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.
