Air Filter

Replace the Air Filter annually and clean it every 90 days. In a dirty environment, or when you start getting frequent temperature alarms, you should always check the intake grilles for debris, and then check the Air Filter to see if it needs to be replaced. If the air in the operating environment is especially dirty, you may have to replace the filter more frequently.

UL Classified

Underwriters Laboratories, Inc has classified Air Filter as Class 2 (flammability only).

  3. Set Bezel assembly face down on a work surface.

  4. Rotate the white pull tab until it clears the Bezel frame clip.
