Air Filter
To clean dust and dirt from the filters, you can use a vacuum cleaner to remove the dirt, or you
can rinse the filter in water. You can also use soaps or mild detergents on the filter. If you rinse the
filter in water, make sure that you squeeze the excess water from it before reinstalling it in the
device.

You might need to slide the chassis forward to enable this procedure.

1.
Using your fingers, push up on the air filter unit from the bottom of the chassis until the filter is
