CHECKOUT
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.

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.
