TROUBLESHOOTING AND SERVICE
WARNING
ELECTRIC SHOCK HAZARD.
CAN CAUSE PERSONAL INJURY OR EQUIP-
MENT DAMAGE.
The following procedures expose hazardous live
parts. Disconnect from power between checks and
proceed carefully. These instructions are only for
use by qualified personnel.
Tools And Equipment
Troubleshooting the electronic air cleaner requires:
•
Needle nose pliers for stringing ionizer wires and
inserting edge connectors.
•
Test meter.
Although a meter is needed for some steps, the primary
diagnostic tools are the
neon light and the test button.

Neon Light (On Power Box)
The neon light is powered through the power supply and is
on when the power supply output voltage is normal.
Test Button
When pushed, the
test button shorts from collector voltage
to ground. The resulting arcing sound indicates that high
voltage is being supplied to the collector. The solid state
power supply controls current flow to the collector. On air
cleaners with a W8600E, the CHECK LED will come on
when the
test button is held down.
Fig. 6. Use an ohmmeter to check the electronic cells
for short circuits.
