Description and where to check
•
Is it immediately after the power supply is turned on?
It takes 3 minutes for preparation. During this period, the compressor does not
operate.
•
Is the power supply off?
Page 12
•
Has the fuse or breaker popped?
•
Is there a power failure?
•
Is it immediately after the operation stops?
To protect the equipment, it does not operate for 3 minutes.
•
Is the button on the remote control pressed while it is pointed at the Infrared signal
receiver on the Indoor unit?
Page 12
•
Is Timer On selected?
Page 21
•
Is the air filter dirty?
•
Are temperature setting, air volume setting and air flow direction adjustment
Page 14, 15, 18, 19
appropriate?
•
Has the unit operating for a long time while the air flow is set to "
Page 18
•
Are the air inlet or outlet of the outdoor unit covered?
•
Is a window or door open?
•
Is it operating for Dry operation?
•
Is it operating in ECO operation?
•
Is it operating to Comfort sleep?
•
Is the "Power selection" set to "75%" or "50%"?
•
Is it off timer for Timer off or Comfort sleep fuction setting?
•
Protection may be activated due to an unreasonable electrical load caused by
voltage variation or covering of the air inlet. Remove any obstructions and reset the
circuit breaker after 30 seconds.
•
Air flow may stop during Heating operation.
•
It may not reach the set temperature depending on the indoor or outdoor conditions
(It is caused by a large difference between set temperature and room temperature
when the operation starts. Ambient temperature is also critical).
•
When the operation stops, the vertical direction louvers fully open once and then close.
•
Vapor may appear due to the rapidly cooled air in the room.
•
Vapor may appear due to condensed water on the heat exchanger, or the panel may
become moist during cooling, dry mode, or inside drying.
•
Are the vertical direction louvers closed or pointing downward? Condensation may
form if operated for a long time in the downward rather than horizontal position
during cooling or dry mode.
•
The outdoor unit may be covered with frost during heating.
•
This is because the melted frost turns to water or steam in order to improve heating
efficiency.
•
Water may drip during cooling or dry mode. This is water condensed from the air
settling on the cool piping.
•
The odor in the walls, carpet, furniture or clothes may be due to natural air
circulation.
