Mist emerges from indoor unit.• Condensation effect due to cooling process.
Water flowing sound during operation.• Refrigerant flow inside the unit.
The room has a peculiar odour.• This may due to damp smell emitted by the wall, carpet, furniture or clothing.
Indoor fan stops occasionally during automatic fan speed setting.• This helps to remove the surrounding odours.
Operation is delayed a few minutes after restart.• The delay is a protection to the unit's compressor.
Outdoor unit emits water/steam.• Condensation or evaporation occurs on pipes.
Timer indicator is always on.• The timer setting repeats daily once set.
Power indicator blinks during operation and the indoor fan is stopped.• The unit is in defrost mode, and the melted frost is drained from the outdoor unit.
Indoor fan stops occasionally during heating operation.• To avoid unintended cooling effect.
Power indicator blinks before the unit is switched on.• This is a preliminary step in preparation for the operation when the ON timer has been set.
Cracking sound can be heard during operation.• Changes of temperature cause the expansion/contraction of the unit.
Heating/Cooling operation is not working efficiently.• Set the temperature correctly.
• Close all doors and windows.
• Clear any obstruction at the air inlet and air outlet vents.
Noisy during operation.• Check if the unit has been installed at an incline.
The unit does not work.• Check if the circuit breaker is tripped.
• Check if timers have been set.

NoiseSound like streaming water during operation or after operation• Sound of refrigerant liquid flowing inside unit
• Sound of drainage water through drain pipe
Cracking noise during operation or when operation stops.Cracking sound due to temperature changes of parts
OdorDischarged air is smelled during operation.Indoor odor components, cigarette odor and cosmetic odor accumurated in the air conditioner and its air is discharged. Unit inside is dusty. Consult your dealer.
DewdropDewdrop gets accumurated near air discharge during operationIndoor moisture is cooled by cool wind and accumulated by dewdrop.
FogFog occurs during operation in cooling mode.• Cleaning is necessary because unit inside (heat exchanger) is dirty. Consult your dealer as technical engineering is required.
(Places where large amounts of oil mist exist at restaurants.)• During defrost operation
Fan is rotating for a while even though operation stops.• Fan rotating makes operation smoothly.
• Fan may sometimes rotates because of drying heat exchanger due to settings.
Wind-direction changes while operating. Wind-direction setting cannot be made. Wind-direction cannot be changed.• When air discharge temperature is low or during defrost operation, horizontal wind flow is made automatically.
• Flap position is occasionally set up individually.
When wind-direction is changed, flap operates several times and stops at designated position.When wind-direction is changed, flap operates after searching for standard position.
DustDust accumulation inside indoor unit is discharged.
At the initial high-speed operation, the fan may sometimes rotate faster (for 3 to 30 minutes) than the setting speed.This is for operation check in order to confirm whether the fan motor rotation is within use range.
No operationWhen power is turned ON instantly.Operation is not activated for the first approx. 3 minutes because compressor
When operation is stopped and resumed circuit is activated.
NoiseNoise often occurs in heating mode.During defrost operation
SteamSteam often occurs in heating mode.
When stopped by remote controller, outdoor unit fan is sometimes operating for a while even though outdoor compressor is stopped.Fan rotating makes operation smoothly.

Air conditioner does not run at all although power is turned on.Power failure or after power failurePress ON/OFF operation button on remote controller again.
Operation button is turned off.• Switch on power if breaker is turned off.
• If breaker has been tripped, consult your dealer without turning it on.
Fuse blow out.If blown out, consult your dealer.
Poor cooling or heating performanceAir intake or air discharge port of indoor and outdoor units is clogged with dust or obstacles.Remove dust or obstruction.
Wind speed switch is set to “Low”.Change to “High” or “Strong”.
Improper temperature settings
Room is exposed to direct sunlight in cooling mode.
Doors and /or windows are open.
Air filter is clogged.Refer to “CARE AND CLEANING”.
Too much heat sources in room in cooling mode.Use minimum heat sources and in a short time.
Too many people in room in cooling mode.Reduce temperature settings or change to “High” or “Strong”.

5. The wireless remote controller or heat pump is malfunctioning.5. Consult your dealer.
6. Batteries in wireless remote controller have run down.6. Replace batteries.
Compressor runs but soon stops.1. Obstruction in front of condenser coil (Outdoor Unit)1. Remove obstruction.
Poor cooling (or heating) performance1. Dirty or clogged air filter1. Clean the air filter to improve the airflow.
2. Heat source or many people in room2. Eliminate heat source if possible.
3. Doors and/or windows are open.3. Shut them to keep the heat (or cold) out.
4. Obstacle near air intake or air discharge port4. Remove it to ensure good airflow.
5. Thermostat is set too high for cooling (or too low for heating).5. Set the temperature lower (or higher).
6. (Outdoor temperature is too low).6. (Try to use a back-up heater.)
7. (Defrosting system does not work.)7. (Consult your dealer.)
Lamps on the indoor unit are flashing.1. Trouble in wiring system1. Contact service center.
