For optimum cooling, verify the condition of the air filter.
Regularly inspect the air filter. A dirty air filter restricts airflow in the unit, producing a
negative effect on the ventilation of the chassis. The filter degrades over time. You
must replace the filter every 6 months.
CAUTION: Always keep the air filter 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.
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.
