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.

Air does not come
out of the air
conditioner.
• 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.
The air conditioner
makes strange
noises.
• 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.
