UNIT DOES NOT OPERATE
The unit will not operate if it is turned on immediately 

after it is turned off. The unit will not operate 

immediately after the mode is changed. This is to 

protect the internal mechanisms. Wait 3 minutes 

before operating the unit.

UNIT DOES NOT SEND OUT WARM AIR 
The unit is preheating or de-icing.

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 

fl owing 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 fl ow  out 

of the outdoor unit during de-icing. 

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.

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.

IDLE
This is because the refrigerant also fl oes through the 

idle indoor unit's pipes when the other unit is operated 

in HEAT mode.

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.

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 

on the indicator panel will indicate”   ” and the 

OPERATION lamp and TIMER lamp will blink 

alternately.)

mode, SELF CLEAN operation)
The other unit(s) is/are de-icing.

IF THE UNIT FAILS TO OPERATE
Check to see if the circuit breaker has tripped or the 

fuse has blown.

ROOM EFFECTIVELY
• Check the fi lters. If dirty, clean them.

• Check the outdoor unit to make sure nothing is 

blocking the air inlet or outlet.

•  Check the thermostat is proper setting. 

•  Make sure windows and doors are closed tightly. 

• A large number of people in the room can prevent 

the unit from achieving the desired temperature.

• Check whether any heat-generating appliances are 

operating in the room.

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.
