Problem Solution
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.
Unpleasant odours
permeate the room.
• If the air conditioner is running in a smoky area or if there is a smell entering
from outside, ventilate the room properly.
• If the air conditioner has not been operated for an extended period of time,
clean the indoor unit and operate the air conditioner in Fan mode for 3 to 4
hours to dry the inside of the indoor unit for removal of unpleasant odours.
• If the air filter blocked with dirt, clean the air filter.
Water drops from the
piping connections of
the outdoor unit.
• Condensation may develop due to the difference in temperature. This is a
normal condition.
