Removing the fan drawer from the chassis
Step 3
If you decide to clean the filter, use one of these cleaning methods:
•
Vacuum cleaner (preferred). You do not need to dry the filter afterwards. Vacuum the filter
until it is clean and free of dust.
•
Plain water. Hold the filter under the water with the metal grid facing toward you and let
the water flow down through the filter. This orientation causes the water to flow through
the filter, in the direction opposite to the usual air flow, so you dislodge rather than embed
matter trapped in the filter. Allow the filter to dry thoroughly before reinstalling it.
•
Hot water and mild detergent. if the filter is too dirty to be completely cleaned with a
vacuum or with plain water, immerse the filter in a solution of hot water and mild
detergent. Rinse the filter thoroughly in plain water and allow it to dry completely before
reinstalling it.
Step 4
Replace the cleaned filter or install the replacement filter by sliding it into its slot near the right
fan tray.
Step 5
Use the Phillips-head screwdriver to tighten the screw and secure the fan drawer panel to the
right fan tray panel.
