2. Once vacuuming is completed on one side of the
COLLECTION CELL, turn the COLLECTION CELL
over and repeat on the other side of the COLLEC-
TION CELL.
NOTE: It is normal for COLLECTION CELLS to
discolor during operation. Vacuuming will not
restore the COLLECTION CELLS to their original
color. However, vacuuming does restore the
COLLECTION CELLS to a high efficiency.

1. Replace the PRE-FILTER into the air cleaner. Ensure
that the "AIRFLOW indicator arrow" on the
PREFILTER is pointing in the same direction as the
"AIRFLOW indicator arrow" on the air cleaner cabinet
as shown in Figure 51.
2. Reinstall the COLLECTION CELLS into the air cleaner.
Ensure the handles on both of the COLLECTION
CELLS are folded flat as shown in Figure 52.
