C) Low temperature heating.
The indoor or outdoor fan stop running when defrosting (Reverse cycle models only).
• Defrosting (Reverse cycle 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.
• Under this condition, the air conditioner will stop heating operation and start defrosting automa-
tically.
• The time to defrost may vary from 6 to 10 minutes according to the outdoor temperature and the
amount of frost build up 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 con-
ditioner 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 run-
ning. 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.
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 louver to the maximum air out-
let 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 decre-
ases accordingly. At the same time, heat loading of the air conditioner increases due to larger diffe-
rence 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 but-
ton on the remote controller to restart operation.
