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.

The shelf life of polyurethane filter varies from two years to five years depending on the storage conditions. Store in a cool, dry, and dark environment. Wrap the media in plastic and store in an environment with relative humidity between 40%- 80% and temperature between 40°F (4° C) to 90°F (32° C). Note that if the material flakes, or becomes brittle when rubbed or deformed, it is no longer usable.

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.
