Air outlet cleaning method 
Separate the air outlet cover by grabbing its protruded section and 
lifting it up.
Clean the safety grille with the soft brush and the suction inlet of 
vacuum cleaner. 
Wash the air outlet cover with soft brush in the running water. 
When assembling after the cleaning, settle the front section of the air 
outlet cover after inserting the cover rear section to suit to the product 
as shown in the right side figure.
•    Clean the air outlet once every 1~2 months.
But the cleaning frequency can differ according to the using environment and time. 
So in an environment where it is dusty, clean more frequently.
