The following events may occur during normal operation.

ROTECTION
OF
THE
A

C
ONDITIONER
C
OMPRESSOR
P
ROTECTION
The compressor can’t restart for 3 minutes after it stops.
Anti-cold air (Cooling and heating models only)
The unit is designed not to blow cold air on HEAT mode, when the indoor
heat exchanger is in one of the following three situations and the set tem-
perature has not been reached.
A) When heating has just starting
B) Defrosting
C) Low temperature heating
The indoor or outdoor fan stop running when defrosting (Cooling and
heating models only).
Defrosting (Cooling and heating models only)
Frost may be generated on the outdoor unit during heat cycle when out-
door temperature is low and humidity is high resulting in lower heating
ef
fi
ciency of the air conditioner.
During this condition air conditioner will stop heating operation and start
defrosting automatically.
The time to defrost may vary from 4 to 10 minutes according to the out-
door temperature and the amount of frost buildup on the outdoor unit.
2. A
WHITE
MIST
COMING
OUT
FROM
THE
INDOOR
UNIT
A white mist may generate due to a large temperature difference between
air inlet and air outlet on COOL mode in an indoor environment that has
a high relative humidity.
A white mist may generate due to moisture generated from defrosting
process when the air conditioner restarts in HEAT mode operation after
defrosting.

OW
N
OISE
OF
THE
A
IR
C
ONDITIONER
You may hear a low hissing sound when the compressor is running or has
just stopped running. This sound is the sound of the refrigerant
fl
owing
or coming to a stop.
You can also hear a low “squeak” sound when the compressor is running
or has just stopped running. This is caused by heat expansion and cold
contraction of the plastic parts in the unit when the temperature is chang-
ing.
A noise may be heard due to louver restoring to its original position when
power is
fi
rst turned on.
