Fan Module Maintenance FAN MODULE MAINTENANCE Continuous airflow to cool the PRU is provided by the Fan Module that is mounted on the top of the PRU chassis. The cooling fans pull the heated air up from the chassis. The heated air is then exhausted through the vent openings at the top of the chassis. This constant movement of air requires that the Fan Module be placed on a maintenance schedule. ANNUAL FAN CHECKUP CAUTION! A mechanical hazard exists due to rotating fan blades.
Fan Module Maintenance Use the following procedure to remove and replace the PRU Fan Module: 1 Read all instructions and procedures of this section prior to beginning work to replace Fan Module. 2 Order a Prism Remote Unit Fan Replacement Kit, catalog number FWP-RUFAN001. 3 Notify the NOC or alarm monitoring system operator that the Fan Module is being replaced, which will generate fan and power alarms for the affected PRU. 4 Power down the PRU and wait until the fans spin down to a stop.
Fan Module Maintenance 9 Remove the old Fan Module from the PRU: a The Fan Module has two keyhole rivets that extend through their designated slots into the sheet metal frame. To disengage the Fan Module keyhole rivets, slide the Fan Module forward approximately 1/4-inch. b Lift the Fan Module straight up to remove it from the PRU chassis. Top of Prism Remote Unit Two cap ve screws Power cable 10 Lower the Fan Module into the PRU from the top.
