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 125 if you need help.
If the filter is undamaged, proceed to clean it. There are several methods for cleaning the air
filter.

Vacuum clean. A few passes of a vacuum cleaner can remove accumulated dust and
dirt.

Oil-free compressor air. Point the compressed air nozzle in the opposite direction of
the filter’s operating airflow (blow from the filter’s exhaust side toward the intake
side).

Cold water rinse. Collected dirt is washed away using a standard hose nozzle with plain
water. Ensure the filter is completely dry before returning to service.

Immersion in warm soapy water. Dip the filter in a solution of warm water and mild
detergent. Then rinse the filter in clear water and let stand until completely dry before
returning to service.
Before returning a filter to service, visually inspect it for tears or rips that may have
occurred during cleaning. Do not reinstall a torn filter as it will be ineffective in trapping
particulates and will interrupt air flow distribution. You may order replacement fan
filters (part number RAF1440) by contacting your Artesyn sales representative.
