The following events may occur during
normal operation.
1. Protection of the air conditioner
Compressor
• The compressor can’t restart for
3-4 minutes after it stops.
2. 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 temperature
has not been reached.
A) When heating has just started.
B) Defrosting.
C) Low temperature heating.
• The indoor or outdoor fan stop running
when defrosting (Cooling and heating
models only).
3. Defrosting (Cooling and heating
models only)
• Frost may be generated on the outdoor
unit during heat cycle when outdoor
temperature is low and humidity is high
resulting in lower heating efficiency 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 outdoor
temperature and the amount of frost
built up on the outdoor unit.
4. 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.
5. Abnormal noise of the air
conditioner
• You may hear a low hissing sound
when the compressor is running or has
just stopped running. It is the sound of
the refrigerant flowing 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 changing.
• A noise may be heard due to louver
restoring to its original position when
power is turned on.
6. Dust is blown out from the indoor
unit
This is a normal condition when the air
conditioner has not been used for a
long time or during first use of the unit.
7. A peculiar smell comes out from
the indoor unit
This is caused by the indoor unit giving
off smells permeated from building
material, from furniture, or smoke.
8. The air conditioner turns to FAN
only mode from COOL or HEAT
(For cooling and heating models
only) mode
When indoor temperature reaches the
temperature setting on air conditioner,
the compressor will stop automatically,
and the air conditioner turns to FAN
only mode. The compressor will start
again when the indoor temperature
rises on COOL mode or falls on HEAT
mode (For cooling and heating models
only) to the set point.
9. The air conditioner runs X-fan (Anti-
mildew) function after turning off
the unit.
When turning off the unit under COOL
and DRY mode, the air conditioner
will run X-fan (Anti-mildew) function for
4 minutes, then stop the operation and
11.
