Caution: BFN series products have safety re-
lay switches where the front and rear fan
guards attach to the unit. These relays dis-
able the fan/ionizer operation when either
fan guard is removed. Take care when attach-
ing the fan guards to assure proper function-
ing of the product.
Periodic Verification:
BFN ionizer have no user serviceable parts and the
technology requires no calibration because of the in-
herently stable ionization output from the AC emis-
sion. Periodic verification is recommended, per ANSI/
ESD SP3.3-2006 Periodic Verification of Air Ionizers.
Verification frequency may be set by the individual
user, but is recommended to be not less than one
time per year. Equipment needed is a Charge Plate
Monitor.
