Cleaning the Fan Filters
The FlexPAC is designed with three independent high performance, forced
cooling systems. The first cooling system channels fresh air directly over the
CPU heat sink and out through a channeled exhaust outlet. The second
system, controlled by an electronic thermostat that regulates the speed of the
fan, circulates fresh air through the add-in card bay. The third system
circulates fresh air past the drive bay and through the power supply.
Additionally, the power supply unit has its own independent fan. Together,
these systems provide excellent internal cooling which helps maintain the
performance of the unit.
Cooling vents are equipped with detachable fan filters that must be
periodically cleaned. The washable fan filters should be cleaned every three to
six months in order to maintain the proper airflow throughout the unit. How
often you clean them depends on the environment or where the FlexPAC is
being used. If it is being used in a factory type environment, the fan filter
should be cleaned once every three months. If the environment is relatively
clean and free of dust pollutants, then once every six months should be
sufficient. You will become more familiar with the cleaning process as time
goes on.
The fan filters are easily accessible and can be cleaned at your convenience.
They are located behind the removable metal screen covers, on each side of
the FlexPAC (see Figure 6.1).
1. Using a 1/16 inch hex driver, remove the hex screws from the metal screen
covers. Be careful not to strip the hex screws while removing them.
2. Carefully lift the screen covers out and away from the FlexPAC.
3. Gently pull the foam fan filters out from their placed positions.
4. Using warm water and a mild soap solution, gently wash each foam fan
filter by hand. Then, let them air dry.
5. When the filters are completely dry, carefully replace them back into their
designated areas.
6. Replace the metal screen covers and insert the hex screws. Using the 1/16
inch hex driver, carefully tighten down each hex screw. Be sure not to over
tighten them.
