Replacing the Air Filter
A replaceable air filter is located on the front of the chassis. How often the air filters should be replaced
depends on the facility environment. In a dirty environment, or when you start getting frequent temperature
alarms, you should always check the intake grills for debris, and then check the air filters to see if they need
to be replaced.
In general, we recommend that you inspect the air filter every three months and replace, if necessary,
every 6 months.
Note
