Clean and replace the air filter
Zhone recommends you clean or replace the MXK air filter every 3 to 6
months.
Cleaning the air filter
Before cleaning the air filter, visually inspect it for damage. If the filter is
damaged, replace it.
When cleaning the filter, avoid using harsh solvents or cleaning agents.
Even though this type of filter may be cleaned, replacement is
recommended every two to three years to ensure media durability and
eliminate residual dust build-up and subsequent air flow resistance.
When the air filter is in good condition, any of the following methods can
be used to clean the filter:
–
Vacuuming.
–
Compressed air. Direct the compressed air in the opposite direction of
normal air flow.
–
Rinsing with cold water. Allow the filter to completely dry before
reinstalling it in the MXK chassis.
