WARNING
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.
CAUTION
The following instructions are for use only by 
qualified personnel.
With all components in place, turn on the air cleaner 
switch and, for forced air (ducted) systems, energize the 
system blower. Check the following points of operation:
1. Verify the neon light or ON light is lighted. The neon 
light comes on to show that the air cleaner is ener-
gized.
2. Turn off the system blower. The neon light or ON 
light should go off.
3. Turn the system blower back on. With the air 
cleaner energized, push the test button. A snapping 
sound indicates that collector voltage is available.
4. With a multispeed blower, repeat steps 1 through 3 
for each fan speed.
5. If operation is not as described, refer to the Trouble-
shooting and Service section.

Tools and Equipment
Troubleshooting the electronic air cleaner requires:
• Needlenose pliers for stringing ionizer wires and 
inserting edge connectors.
• Test meter with 15 kVdc probe or equivalent. The 
electronic air cleaner troubleshooting charts, Fig. 21 
and 22, show how to quickly isolate a problem in the air 
cleaner. Although a meter is needed for some steps, 
see Fig. 23, the primary diagnostic tools are the neon 
light and the test button.
Test Button
When pushed, the test button shorts from collector 
voltage to ground. See internal schematics, Fig. 7 through 
Fig. 20. The resulting arcing sounds indicate that high 
voltage is being supplied to the collector. The solid-state 
power supply controls current flow to the collector.
Power Supply
WARNING
Electric Shock Hazard.
Can cause personal injury.
Always turn off power and remove access door or 
grille before removing power box or its cover.
The solid state power supply assembly has no field 
serviceable components. When troubleshooting indicates 
a power supply or solid state performance indicator 
problem, replace the entire power supply assembly.
