Maintaining Air Filters
Routine filter maintenance is required to ensure that the shelf operates efficiently. The
following section provides the information needed to replace and store filters.
4.9.1
Replacing the System Filters
The shelf is equipped with two air filters which are located below and above the front fan tray.
System Damage
Air Filters
Air contamination can pollute the air filters and obstruct the air intake of the system which
may cause system overheating and component damage.
To guarantee proper airflow through the system the air filters have to be replaced at least
every six months. Emerson recommends to replace the air filters every 90 days. Filter
replacement frequency depends on the environment the system is subjected to.
Because central offices vary in physical location and cleanliness, check your air filters every
week after you first install your system. In a dusty environment, filter replacement may be
required more often than in a cleaner environment. Check the filters frequently until you
have a good idea of how often they must be replaced. Based on your findings, establish a
regular replacement schedule and keep a log to record the date of each filter replacement.
Filter Frames
Wrong insertion may damage the frame or the guides.
When inserting the filter frame into the shelf, pay attention to insert the appropriate
bottom or top frame and to align it accurately to the guides.
Damage of Circuits
Electrostatic discharge and incorrect installation and removal of the product can damage
circuits or shorten their life.
Before touching the product make sure that your are working in an ESD-safe environment
or wear an ESD wrist strap or ESD shoes. Hold the product by its edges and do not touch any
components or circuits.
