Electric Shock Hazard.
Can cause personal injury or equipment damage.
The following procedures expose hazardous live parts.
Disconnect power supply between checks and
proceed carefully.

personnel only.
Tools and Equipment
Troubleshooting the electronic air cleaner requires only a few
tools:
• Needlenose pliers for stringing ionizer wires.
• Test meter.
Troubleshooting Procedure
The Electronic Air Cleaner Troubleshooting Charts, Fig. 34
and 35, show how to quickly isolate a problem in the air
cleaner. Although a meter is needed for some steps, (see
Fig. 33) the primary diagnostic tools are the neon light on air
cleaners without a W8600E, the CHECK LED on air cleaners
with W8600E, and the test button.
Fig. 32. You must remove two-cell model power box from
air cleaner to remove cover.
Fig. 33. Use an ohmmeter to check the electronic cells
for short circuits.
