working.
• Check if you have selected Fan/Turbo mode. In these modes,
desired temperature is set to auto and you cannot adjust the

lower(during Heat mode) than the current temperature. Press the
Temp + or - button on the remote controller to change the set
temperature.
• Check if the Air lter is blocked by dirt. If there is a lot of dust on the
Air lter, cooling(heating) performance may decrease. Clean them
frequently.

Take the cover o and take the obstacle away.
• If you want to operate the air conditioner in the sunlight, cover the
outdoor unit using curtains or etc.

ice formed in winter or the outdoor temperature is too low, the air
conditioner operates in De-ice mode automatically. In De-ice mode,
indoor fan stops and cool air does not come out.
• If the doors or windows are open, it may cause bad cooling

Close the doors and windows.
• Check if the air conditioner has just been turned on after stopping
cooling or heating operation. In this case, just a fan will run to
protect the outdoor unit compressor.
• Check if the pipe length is too long. When the pipe length exceeds
maximum allowable pipe length, cooling (heating) performance
may decrease.
Air ow adjustment
is not working.

modes, desired temperature is set to auto and you cannot adjust
the temperature.
