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.
