Reinstall the Cells and Prefilters
1. Inspect the cells for broken ionizer wires and bent
collector plates. Repair as necessary or take to a
Honeywell Authorized Air Cleaner Repair Station.
2. Slide the prefilters into the upstream prefilter guides.
3. Slide in the air cleaner cells so the airflow arrow points
downstream and the handles faces outward.
4. Firmly close the access door.
5. Turn on the air cleaner. If the cells and prefilters are
wet, the neon light may not come on and you may hear
arcing. If the arcing is annoying, simply turn off the air
cleaner for two to three hours or until the cells is dry.
If the air cleaner has a Remote Performance Indicator, the
FAULT indicator may activate when the cells and prefilters are
wet. Again, if the FAULT indicator is annoying, simply turn off
the air cleaner for two to three hours or until the cells and
prefilters are dry.
Replacing Ionizer Wires
Broken or bent ionizer wires can cause an electrical short to
ground, often resulting in visible arcing or sparking. Do not
use cells until broken wires are removed. Cells can be used
temporarily with one wire missing, but replace the wire as
soon as possible.
Replacement wires are supplied cut to length with eyelets on
both ends 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. 21. 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.
3. Check the cell for short circuits using an ohmmeter.
Check the resistance between the frame of the cell and
both the ionizer and the collector contacts. In each
case, the resistance should be infinite. See Fig. 22.
