• Check whether the air conditioner is running

 

 

 

 

 

 

 

 

 

 

 

 

 

the defrost function. When ice forms in

 

 

 

 

 

 

 

 

 

 

 

 

 

winter or the outdoor temperature is too low,

 

 

 

 

 

 

 

 

 

 

 

 

 

the air conditioner runs the defrost function

 

 

 

 

 

 

 

 

 

 

 

 

 

automatically. While this function is running,

 

 

 

 

 

 

 

 

 

 

 

 

 

the indoor fan stops and warm air does not

• Check whether the air conditioner is turned

 

 

 

 

 

 

 

 

 

 

 

 

 

on immediately after the cooling or heating

 

 

 

 

 

 

 

 

 

 

 

 

 

operation stops. In this case, only the fan

 

 

 

 

 

 

 

 

 

 

 

 

 

runs to protect the outdoor unit compressor.

 

 

 

 

 

 

 

 

 

 

 

 

• Check whether the pipe length is too long.

 

 

 

 

 

 

 

 

 

 

 

 

 

When the pipe length exceeds the maximum

 

 

 

 

 

 

 

 

 

 

 

 

 

pipe length, the cooling and heating

 

 

 

 

 

 

 

 

 

 

 

 

 

performance may decrease.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

• Check whether the good'sleep function is
