Maintaining the MX960 Air Filter

Purpose
For optimum cooling, verify the condition of the air filters.
Action
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:
the fans are very powerful, they could pull small bits of wire or other materials
into the through the unfiltered air intake. This could damage the 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.
