NOTICE
Do not clean the air cleaner element until the air cleaner
clogging symbol on the monitor panel flashes. If the element
is cleaned frequently before the clogging monitor flashes,
the air cleaner will not be able to display its performance
fully, and the cleaning efficiency will also go down.
In addition, during the cleaning operation, more dirt stuck to
the element will fall inside the inner element.
