• 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.
• 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.
• When you press the
may be heard from the drain pump inside the air conditioner. This noise
is a normal sound.
• If the air conditioner is running in a smoky area or if there is a smell
entering from outside, ventilate the room properly.
• If both indoor temperature and indoor humidity are high, operate the air
conditioner in the Clean or Fan mode for 1 to 2 hours.
• If the air conditioner has not been operated for an extended period of
time, clean the indoor unit and then operate the air conditioner in the
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.
• In winter, if the indoor humidity is high, steam may be produced around
the air outlet while the defrost function is running. This is a normal
operation.
• When the air conditioner is turned off, the outdoor unit fan may
continue to operate to reduce noise of the refrigerant gas. This is a
normal operation.
• Condensation may develop due to the difference in temperature. This is
a normal condition.
• In winter, when the air conditioner runs in the Heat mode, the frost on
the heat exchanger melts and steam may be produced. This is a normal
operation, neither product malfunction nor a fire.
