be kept clean by periodic vacuuming, and should be replaced if it becomes torn, worn,
or dirty. You can access the filter while the system is operating by removing the bottom
front chassis panel. The blower, which is located in the front interior of the chassis, need
only be replaced if the existing blower fails. You must turn all system power off and
