Installing Activated Carbon Filters,
Cells, and Prefilters
1.
Insert the activated carbon filters (if used) into the
channel guides closest to the fan.
2.
Inspect the cells for broken ionizer wires and bent
collector plates. Moderately bent or warped collector
plates can be bent back into shape. Broken ionizer
wires must be replaced for top efficiency as instructed
on page 15.
3.
Insert the cells into the channel guides until they touch
the back stop of the F90. Assure the cell airflow arrow
is pointing toward the fan. In this position, the ionizer
wires are facing downward (away from the fan).
4.
Insert the prefilters into the channel guides until they
touch the back of the channels.
