Environmental factors can decrease the amount of time required between fan replacements. Check the environmental factors regularly. An
increase in temperature and particulate matter in the air might affect performance—for example, new equipment installation.
CAUTION:
Check the fans at six-month intervals, and replace them as necessary. Regularly monitor the speeds of the fans to
accurately determine replacement intervals.
