If the air cleaner is installed adjacent to a 90° duct elbow,
add turning vanes inside the duct to improve the air
distribution across the face of the air cleaner (Figure 9).
Failure to follow this recommendation can reduce the
efficiency of the electronic air cleaner.

The air cleaner is set up for a left to right airflow, when facing the access door. For a right to left airflow, follow these
directions:
Figure 9
Figure 10
Figure 11
1. Remove the pre-filter and cells from the cabinet. A
plastic positioning spacer is located inside the bot-
tom of the cabinet (Figure 11) to allow installation of
the cells in the proper position with respect to airflow.
2. Remove the screw securing the spacer to the cabi-
net.
3. Reposition the spacer in the alternate hole at the bot-
tom of the cabinet closest to the airflow exit side of
the cabinet. Secure with the screw removed in step
2.
4. Seal the unused hole with duct tape.
5. Remove the cell handle and reattach to the opposite
end of the cell. Turn cells around, replace in cabinet.
6. Replace pre-filters on the airflow entrance side of the
cabinet. NOTE: The directional arrows on the cell
end plates must point in the direction of airflow.
