Maintaining the T1600 Air Filters

Purpose

For optimum cooling, verify the condition of the air filters.

Air filters for both the front and rear fan trays help keep dust and other particles from entering the cooling system. To function properly, the entire cooling system requires an unobstructed airflow and proper clearance around the site, as described in Clearance Requirements for Airflow and T1600 Hardware Maintenance .

Action

Check the air filters regularly for dust and debris. The filter elements degrade over time, so the filter elements in use, must be replaced every 6 months. For procedures to replace the air filters, see Replacing the T1600 Rear Air Filter and Replacing the T1600 Front Air Filter.

Use spare filter elements within one year of manufacture. Check the date of manufacture printed on the filter. Store spare filter elements in a dark, cool, and dry place. Storing the filter elements at higher temperatures, or where they can be exposed to ultraviolet (UV) radiation, hydrocarbon emissions, or vapors from solvents, can significantly reduce their life.

Caution: Always keep both air filters in place while the router is operating. Because the fans are very powerful, they could pull small bits of wire or other materials into the router through the unfiltered air intake. This could damage the router components.
