TROUBLESHOOTING Til'S
Nonnal function of the air conditioner
The following events may occur during normal operation.
1. Protection of the air conditioner.
Compressor protedion
• The compressor can't restart for 3-4 minutes after it stops.
Anti-cold air (Cooling and heating models only}
• The unit is designed not to blew 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).
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 condRioner 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.
2. A white mist corning 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.
3. Low 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 "squeakR 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
'Nhen the temperature is changing.
• A noise may be heard due to louver restoring to its original position when pOYJer is turned on.
4. 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
5. 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.
6. The air conditiooer turns to FAN only mode from COOL or HEAT (For cooling and
heating models only} mode.
When indoor temperature reaches the 1emperature setting on air conditioner, the compressor
will
stop automatically, and the air oonditioner turns to FAN only mcxle. The compressor will start again
when the indoor temperature rises on COOL mode or falls on HEAT mode (Fa cooling and heating
models only)
to
the set point.
