Under this condition, the air conditioner will stop heating operation and start defrosting
automatically.
The time to defrost may vary from 6 to 10 minutes according to the outdoor 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.
3. 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 louvre restoring to its original position when power is first
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 conditioner turns to FAN only mode from COOL or HEAT (reverse cycle 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
(reverse cycle models only) to the set point.
7. 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 louvre to the
maximum air outlet position and select HIGH fan speed.
8. Heating mode (Reverse cycle 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.
9. Auto-restart function
After the power cut-off, the air conditioners can automatically restore the previous function setting.
10. 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.
