Internal Fan Cleaning
After removing both front and rear fan guards, the emit-
ter points and fan assembly will be unobstructed, for easy
deep cleaning. Use a soft brush, Isopropyl Alcohol and
compressed air to remove any foreign matter.
Note:
The frequency of cleaning required for optimal per-
formance from BFN ionizers depends on the environment
in which the BFN series ionizer operates.
When finished cleaning, replace both front and rear fan
guards.
