HOWTO CHANGETHE CERAMIC FILTERS
This model is used two ceramic filters of CF1 and CF3.
You must used same type of color marked ceramic filters in order
to meet same specifications.
Therefore, the ceramic filter must changed two pieces together
since it's supply two pieces in one package as a spare parts.
