Operation Tips
The following events may occur during normal operation:
1. Protection of the air conditioner.
• Compressor protection
The compressor can't restart for 3 minutes after it stops
• Anti-freezing
If the unit is operating in COOL mode and in low
ambient temperature, frost may be formed on the heat
exchanger. When indoor heat exchanger temperature
decreases below 0ºC, the compressor will stop
operation to protect the unit.
• Defrosting
Frost may form on the outdoor unit in heating operation
when the outdoor temperature is low but humidity is
high, resulting in low heating efficiency.
During this condition the air conditioner will stop heating
operation and start defrosting automatically. The time to
defrost may vary from 3 to 12 minutes.
During defrosting, the fan motors of indoor unit and
outdoor unit will stop, the indoor indicator flashes
"H1 "and the outdoor unit may emit vapor. This is not
malfunction. After defrosting is finished, the heating
operation will recover automatically.
• Anti-cold air
In HEAT mode, the indoor fan will not operate in order
to prevent cold air being blown into the room (within 5
minutes), if the indoor heat exchanger does not reach a
minimum temperature under the following states:
(1) Heating operation just start.
(2) After auto defrosting is just finished.
(3) Heating at low temperature.
2. Gentle breeze
The indoor unit may blow gentle breeze and the louver
rotate to a certain position in the following situation:
(1) In HEAT mode, the unit is turned on, the compressor
does not reach the starting condition.
(2) In HEAT mode, the temperature reaches the set value
and the compressor stops running for about 1 minute.
3. 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 in 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.
4. Low noise of the air conditioner
• You may hear a low hissing sound when the
compressor is running or has just stop running. This is
the sound of the refrigerant flowing or coming to a stop.
• You also may hear a low "squeak" sound when the
compressor is running or 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 furst turned on.
5. D ust 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.
6. A peculiar smell comes out from the indoor unit
This is caused by the indoor unit giving off smells permeated
from building material, furniture or smoke.
7. T he air conditioner turnes to FAN only mode from COOL or
HEAT mode
When the indoor temperature reaches the setting value, the
compressor will stop automatically, and the air conditioner turns
to FAN mode.
The compressor will start again when the indoor temperature
rises in COOL mode or falls in HEAT mode to the set point.
8. Condensation
Condensate water is likely to form at the air outlet if cooling or
drying for a long time when the relative humidity is more than
80% (with doors and windows open).
Set the vertical louver to its maximum angle (to the floor) and
High fan speed. Close the doors and windows.
9. L ighting 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 ON/OFF
button on the remote control to restart operation.
10. Clean function
The indoor unit may keep running after you switch off the unit by
pressing ON/OFF button.
Please check whether the Clean function is switched off.
