Problem
Solutionz
The air is not cool
or warm enough.
ŷ
Both cooling and heating do not operate in the Fan mode. Select the
Cool, Heat, Auto, or Dry mode.
ŷ
Check whether the air filter is blocked with dirt. A dusty filter may
decrease the cooling and heating efficiencies. Clean the air filter
frequently.
ŷ
If a cover is on the outdoor unit or any obstacle is present near the
outdoor unit, remove them.
ŷ
Install the outdoor unit in a well-ventilated place. Avoiding places
exposed to direct sunlight or close to a heating appliance.
ŷ
Place a sunscreen over the outdoor unit to protect it from direct
sunlight.
ŷ
If the indoor unit is installed in a place exposed to direct sunlight,
pull the curtains on the windows.
ŷ
Close the windows and doors to maximize the cooling and heating
efficiencies.
ŷ
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.
ŷ
When the Heat mode is started, warm air does not come out
immediately to prevent cool air from coming out at the beginning.
ŷ
If the refrigerant pipe is too long, the cooling and heating
efficiencies may be decreased. Avoid exceeding the maximum pipe
length.
The air conditioner
makes strange
noises.
ŷ
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.
ŷ
When you press the
(Power) button on the remote control, noise
may be heard from the drain pump inside the air conditioner. This
noise is a normal sound.
Unpleasant odours
permeate the
room.
ŷ
If the air conditioner is running in a smoky area or if there is a smell
entering from outside, ventilate the room properly.
ŷ
If both indoor temperature and indoor humidity are high, operate
the air conditioner in the Clean or Fan mode for 1 to 2 hours.
ŷ
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.
ŷ
If the air filter blocked with dirt, clean the air filter.
