ANNUAL FAN CHECKUP
CAUTION! A mechanical hazard exists due to rotating fan blades. Keep hands and fingers away from fan
blades during removal of Fan Module. Use only the designated pull areas to disengage the fan
tray. Allow adequate time for fans to spin down prior to removal.

REPLACING THE FAN MODULE
CAUTION! The rotating fan blades create a hazardous environment. Keep hands and fingers away from
the fan blades. Use only the designated pull areas to disengage the Fan Tray. Allow adequate
time for fans to spin down prior to removal.
CAUTION! Low voltage electrical shock hazard!
• Do not touch bare conductors or other potentially energized parts.
• Use appropriate safety equipment approved for use on electrical installations.
• Ensure fan module exterior of electrical connector and immediate area are clean and dry
prior to disconnection.
• Do not perform service during or while conditions of impending rain or snow are observed.
NOTE: You do not need to disconnect the power cabling from the Prism Remote Unit to replace the
Fan Module.
NOTE: If the PRU has an Enhanced Fan Shroud, refer to the FlexWave Prism Remote Unit Enhanced
Fan Shroud Installation Guide (TECP-77-235) for information on how to replace the Fan
Module.
