Operation tips
The following events may occur during normal operation.
Protection of the air conditioner.
Compressor protection
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 temperature
has not been reached.
1. When heating has just starting.
2. Defrosting.
3. Low temperature heating.
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 buildup on the outdoor unit.
The indoor or outdoor fan stop running when defrosting (Cooling and heating
models only).
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.
Low noise of the air conditioner
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 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 first turned on.
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.

vacuum cleaner or water. After, dry for
a couple of hours or until dry.
7. Insert the fresh air filter in its original
place.
8. Insert the high part of the air filter
(fresh air Support frame)
again in the unit keeping in mind
that the outside border (right and
left) are lined up correctly, now
place the whole filter in the initial
position.
Maintenance
If you plan to idle the unit for a long time, perform the following:
1. Operate the fan for about half a day to dry the inside of the unit.
2. Stop the air conditioner and disconnect power. Remove the batteries from
the remote controller.
3. The outdoor unit requires periodic maintenance and cleaning. Do not
attempt to do this yourself. Contact your dealer or servicer.
Checks before operation
1. Check that the wiring is not broken off or disconnected.
2. Check that the air filter is installed
3. Check if the air outlet or inlet is blocked after the air conditioner has not
been used for a long time.
