Removing Specific Contaminants
from Cells
The following list gives the appropriate cleaning procedure
for types of contamination often found on cells and prefilters.
Cleaning procedures are listed in order of preference. Be
careful to avoid bending the cell collector plates.
Reinstalling the Cells, Prefilter and
Activated Carbon Filters, If Used
• Inspect the cells for broken ionizer wires and bent collector
plates. Bend warped or bent collector plates back into
shape. For maximum efficiency, replace broken ionizer
wires as instructed in Replacing Ionizer Wires section.
• Wipe ionizer wires.
• Check that cells are completely dry before reinstalling in the
air cleaner. If cells are placed into the air cleaner while still
wet, the electronic cells can short out and arc frequently
when almost dry. Although the system appears to be oper-
ating, the cells may not be cleaning during the drying period.
• Be sure the contact board of the cell is facing the latch side
of the frame.
• Check that the airflow arrow is pointing toward the fan. In
this position, the ionizer wire side of the cell is the farthest
from the fan.
• Ease the edge of the cell into the cell hooks.
• Using both hands, pivot the cell until the contact board
mates with the frame.
• With one hand supporting the cell near the latch, rotate the
latch to a closed position. See Fig. 14.
• Wipe surface dirt from the inside and the outside
of the grille.
• Replace the prefilter in the grille. Be sure that the airflow
arrow is pointing toward the cells.
• Replace activated carbon filters, if used. The F57A carbon
filters fit inside the grille, one on each side of the prefilter.
The F57B carbon filter fits inside the grille on the left side of
the prefilter.
• Close and carefully latch the grille.

Replacing Ionizer Wires
Broken or bent ionizer wires can cause an electrical short to
ground, often resulting in visible arcing or sparking. Remove
broken wires. Cells can be used temporarily with one wire
missing, but replace the wire as soon as possible.
Replacement wires, part no. 136434AA, are cut to length with
eyelets on both sides for easy installation. To install:
1. Hook the eyelet on one end of the wire over the spring
connector on one end of the cell. See Fig. 15. Be careful
to avoid damaging the spring connector or other parts
of the cell.
2. Hold the opposite eyelet with a needlenose pliers and
stretch the wire the length of the cell. Depress the
opposite spring connector and hook the eyelet over it.
