If the LD303 is on, the product is not performing air purification. It is performing cooling or heating.
If the LD303 is on and if the LD301 or LD302 are on, the product is running with a heavy load. (This does not
constitute a failure.)
If the LD303 is off and if the LD301 is blinking, conduct a check according to the check procedure after an
operation as described below.
Identify the failure location.
