When the primary air filter element is cleaned, check for rips or tears in the filter material. The primary air filter element should be replaced at least one time per 2-year period. This replacement should be performed regardless of the number of cleanings.
Do not clean the air filter elements by bumping or tapping. This could damage the seals. Do not use elements with damaged pleats,
