How to install Chief Plenum Rated Fan Kit - Silver

• Prepare the installation area by powering down all connected AV equipment and isolating the circuit feeding the CMS housing to ensure safe work conditions before beginning the installation.
• Identify the Chief CMS storage box housing in the above-tile ceiling space and verify there is adequate clearance around the mounting area for the fan kit and wiring paths.
• Position the fan kit so its mounting points align with the housing’s attachment points. Confirm that the orientation supports optimal airflow direction for heat removal from the AV components inside the box.
• Secure the kit to the housing using the two screws provided. Tighten evenly to ensure a solid, vibration-free connection without over-tightening, which could distort the housing or affect airflow.
• Connect the 12V DC power supply according to local electrical codes. If you’re using the NAFT85 inline thermostat for automatic temperature control, install the thermostat inline within the fan circuit as specified by its instructions, ensuring proper polarity and secure connections.
• Restore power and test the system. Verify that the fan engages correctly, verify airflow through the CMS housing, and confirm that any thermostat-based control operates as intended. Listen for abnormal noise and check for vibration, adjusting mounting if necessary.
