Caution: BFN series products have safety relay
switches where the front and rear fan guards at-
tach to the unit. These relays disable the fan/
ionizer operation when either fan guard is re-
moved. Take care when attaching the fan guards
to assure proper functioning of the product.
Periodic Verification:
BFN ionizer have no user serviceable parts and the
technology requires no calibration because of the inher-
ently stable ionization output from the AC emission. Pe-
riodic verification is recommended, per ANSI/ESD
SP3.3-2006 Periodic Verification of Air Ionizers. Verifi-
cation frequency may be set by the individual user, but
is recommended to be not less than one time per year.
