Maintenance 46
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
47 Operation tips
long time or during first use of the unit.
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.
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 o ly)
to the set point.
Dripping water may generate on the surface of the indoor unit when cooling in
a high relatively humidity (relative humidity higher than 80%). Adjust the
horizontal louver to the maximum air outlet position and select HIGH fan
speed.
Heating mode (For cooling and heating models only)
The air conditioner draws in heat from the outdoor unit and releases it via the
indoor unit during heating operation. When the outdoor temperature falls,
heat drawn in by the air conditioner decreases accordingly. At the same time,
heat loading of the air conditioner increases due to larger difference between
indoor and outdoor temperature. If a comfortable temperature can't be
achieved by the air conditioner, we suggest you use a supplementary heating
device.
Auto-restart function
Power failure during operation will stop the unit completely.
For the unit without Auto-restart feature, when the power restores, the
OPERATION indicator on the indoor unit starts flashing. To restart the
operation, push the ON/OFF button on the remote controller. For the unit with
Auto-restart feature, when the power restores, the unit restarts automatically
with all the previous settings preserved by the memory function.
Lightning or a car wireless telephone operating nearby may cause the
unit to malfunction.
Disconnect the unit with power and then re-connect the unit with power again.
Push the ON/OFF button on the remote controller to restart operation.
