ODORS
Carpet and furniture odors that entered into the unit may be sent out from the unit.
CRACKING NOISE
The unit may produce a cracking noise. This sound is generated by the friction of the front panel and other components expanding or connecting due to a temperature change.
A LOW BUZZING NOISE EMITTED
This is a sound emitted when the unit is generating Plasmacluster ions.
SWISHING NOISE
The soft, swishing noise is the sound of the refrigerant flowing inside the unit.
WATER VAPOUR
•In the COOL and DRY operation, water vapour can sometimes be seen at the air outlet due to the difference between the room air temperature and the air discharged by the unit.
•In the HEAT operation, water vapour may flow out of the outdoor unit during
THE OUTDOOR UNIT DOES NOT STOP
After stopping the operation, the outdoor unit will rotate its' fan for about a minute to cool down the unit.
ODOR EMITTED FROM THE PLASMACLUSTER AIR OUTLET
This is the smell of ozone generated from the Plasmacluster Ion generator. The ozone concentration is very small, posing no adverse effect on your health. The ozone discharged into the air rapidly decomposes, and its density in the room will not increase.
When using your air conditioner with multi- system
INDOOR UNIT BECOMES WARM EVEN WHEN IDLE
This is because the refrigerant also floes through the idle indoor unit's pipes when the other unit is operated in HEAT mode.
INDOOR UNIT BECOMES WARM EVEN WHEN NOT DURING HEATING OPERATION
When the PLASMACLUSTER button is pressed while the unit is not operating, the PLASMACLUSTER operation will be performed without accompanying air conditioning mode (eg. HEATING or COOLING). At this time, you may feel warm air coming out from the unit air outlet if HEATING is performed with units in other rooms. Indoor fan will decrease its rotating speed and will turn ON and OFF depending on the room temperature.
UNIT DOES NOT OPERATE IN YOUR REQUESTED MODE
•When one indoor unit is operating in COOL or DRY mode, you can not operate the other unit in HEAT mode. (After a few seconds, a long BEEP will be emitted, and the temperature indicator
on the indicator panel will indicate” ” and the OPERATION lamp and TIMER lamp will blink alternately.)
•When one indoor unit is operating in HEAT mode, you can not operate the other unit in COOL nor DRY mode. (After a few seconds, a long BEEP will be emitted, and the temperature indicator

•Check whether any
IF THE UNIT FAILS TO RECEIVE THE REMOTE CONTROL SIGNAL
•Check whether the remote control batteries have become old and weak.
•Try to send the signal again with the remote control pointed properly towards the unit’s signal receiver window.
•Check whether the remote control batteries are installed with the polarities properly aligned.
Please call for service when TEMPERATURE INDICATOR on the indicator panel blink.
