12. OPERATION TIPS
The following events may occur during normal operation of the air conditioner :
1. A slight white mist (water vapor)coming out from the indoor unit during COOL mode
ƒ 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.
The cool air from the indoor unit is coming into contact with the room air.
ƒ A white mist may generate due to moisture generated from defrosting process when the air
conditioner restarts in HEAT mode operation after defrosting (only for heat pump system ).
2. Low noise of the air conditioner
ƒ You may hear a low hissing sound when the air conditioner is running or has just stopped running.
This sound is the sound of the refrigerant beginning to circulate or an adjustment of the refrigerant
pressures after stopping.
ƒ You can also hear a low short "squeak" when the indoor unit is in operation or when it has stopped.
These are generally due to the temperature changes on the plastic parts ( expansion or contraction ).
ƒ A noise may be heard due to louver restoring to its original position when power is first turned on.
3. 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.
4. Unpleasant smells coming out from the indoor unit.
ƒ Unpleasant smells can be caused by substances accumulated in the air filters of indoor unit.
ƒ In this case, you must switch the system off and air filters must be cleaned.
ƒ Restart the indoor unit in ventilation ( fan only ) mode and open windows to change the room air.
5. The air conditioner turns to FAN only mode from COOL mode or HEAT 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 to the set point.
6. Dripping water may generate on the surface of the indoor unit during COOL mode
in a high relative humidity (higher than 80%).
Adjust the horizontal louvers to the maximum air outlet position and select HIGH fan speed.
7. Mist (water vapor) coming out from the outdoor unit during HEAT mode
It is normal in heat pump operation when defrost is automatically activated during heating operation
at very low ambient temperature ( only for heat pump system ).
8. Lightning or a car wireless telephone operating nearby may cause the system
to malfunction.
Disconnect the system with power and then re-connect the system with power again.
Press ON/OFF button on the remote control to restart operation.
