Fractal Design Define XL R2 Titanium Grey - Manual (Page 5)

Cleaning the filters
Define XL R2 is equipped with two particle filters at air intakes to prevent dust from entering
the case. To ensure optimal cooling, filters should be cleaned on a regular basis.
• To clean the PSU filter, simply slide the filter toward the rear of the case and remove
it; clean any dust gathered on it.
• To clean the front filter, open the front door panel and push the symbols on the hatch
to open the fan door. To completely remove fan filter, pull down the lever on the top of
the filter. Once removed, the filter can then be cleaned directly by hand or with water if
fans have been removed.

Power/HDD LED activity
Define XL R2 features an LED on the front panel that, when lit, indicates the computer is
receiving power. By changing its connection on the motherboard, the LED can be used to
indicate HDD activity. In either case, connecting the LED to the motherboard is optional;
computer functionality is not dependent on its connection.
