Fan air filter replacement
Environmental factors can decrease the amount of time required between air filter replacements. Check the environmental factors regularly.
An increase in temperature and/or particulate matter in the air might affect performance.
CAUTION:
Check the fan air filters at six-month intervals and replace them as necessary. To accurately determine air filter
replacement intervals, regularly monitor the speeds of the cooling fans. An increase in overall fan speed may indicate a clogged
filter.
You must replace the fan air filters with new filters; you cannot clean and reuse the old fan air filters. Replacement filter media must meet
the requirements found in GR-63-CORE.
