4.7 Air Filter Maintenance
Air filters should be cleaned every 90 days or sooner, depending on the conditions of the
Central Office Environment. 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, a
filter may need cleaning more often than a filter in a cleaner environment. Check the filters
frequently until you have a good idea of how often it needs cleaning. Based on your findings,
establish a regular cleaning schedule and keep a log to record the date of each filter cleaning or
replacement.
Air filters should also be checked occasionally to make sure they are not obstructed or
damaged. Visually inspect filters for tears or rips. Do not reinstall a torn filter as it will be
ineffective in trapping particulates and will interrupt air flow distribution. To maintain safety
certification, use only Artesyn approved fan filters. You can order replacement fan filters (part
number RAF640) by contacting your Artesyn sales representative.
For replacement procedures, refer to Replacing the Fan Filter on page 162 .
4.8 Cleaning the Air Filter
To ensure the AXP640 shelf operates properly, routine filter maintenance is required as
discussed in
Air Filter Maintenance . Maintenance includes cleaning, replacing, and properly
storing the air filters.
Filter cleaning frequency depends on the environment the system is subjected to. The shelf
filter requires routine cleaning to ensure effective filtration and airflow. To prevent air
contamination from polluting the air filter and possibly obstructing the air intake of the
system, the air filter should be replaced according to the schedule you have established based
on your Central Office Environment as discussed in
Air Filter Maintenance .
Remove and inspect the filter for tears or damage before cleaning it. If the filter is torn or
damaged, discard the filter and replace it with a new one. Refer to
Replacing the Fan Filter on
page 162 if you need help.
If the filter is undamaged, proceed to clean it. There are several methods for cleaning the air
filter.
1. Vacuum clean. A few passes of a vacuum cleaner can remove accumulated dust and
dirt.
