How To Replace Ionizer
!!Unplug The Purifier Before Servicing!!
The Ionizer is located in a small plastic holder right in front of the fan. You are able to see it if
you remove the front fan cover but will not be able to replace it this way.
The Center Housing and Fan (you will not have to remove the Negative Ion Attracting Plate)
will need to be removed in order to access the Ionizer and Ionizer holder.
The Ionizer holder will slide out of the securing slot. Insert the new Ionizer into the holder and
put back into place.
Make sure you connect the Ionizer quick connect plug back with its correct location.
