60 Hz to 220/240 Vac, 50/60 Hz. The kit includes a trans-
former and two screws. The line cord on the air cleaner
must be changed to conduit to complete the conversion.
NOTE: The air cleaner can be completely isolated from
the electrical circuit of the HVAC system unless re-
quired by local code to use same circuit. Any convenient
house circuit can power the air cleaner, regardless of
electrical rating of HVAC system.

TOOLS AND EQUIPMENT
Troubleshooting the electronic air cleaner requires:
Checkout
•
Needle nose pliers for stringing ionizer wires and
inserting edge connectors.
WARNING
!
•
Test meter.
ELECTRIC SHOCK HAZARD.
CAN CAUSE PERSONAL INJURY OR
EQUIPMENT DAMAGE.
The following procedures expose hazardous live
parts. Disconnect from power supply between
checks and proceed carefully. These instructions
are for use by only qualified personnel.
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.
With all components in place, connect power to the air
cleaner. Turn on the air cleaner switch to energize the
system blower. Check the following points of operation:
1. The neon light next to the on-off switch is on. If a
W8600E is part of the installation, check the wall panel
and make sure the ON LED is lit. The W8600E CHECK
LED will come on if there is a problem with the high
voltage power supply.
2. Turn off the system blower. The neon light should
go off after a few seconds. The neon light indicates that
the air cleaner is energized and the high voltage power
supply is working properly.
CHECK LED (Air Cleaners with W8600E)
The CHECK LED is on the W8600E. It lights to indicate
the following problems: excessive dirt loading (beyond
that required to activate the WASH LED), partial shorting
of the collector, continuous ionizer or collector arcing,
power supply failure, excessive ionizer current, or any
condition causing a major reduction in high voltage.
3. Turn on the system blower. With the air cleaner
energized, push the test button. A snapping sound indi-
cates that the collector voltage is present on the cell. The
W8600E CHECK LED will come on when the test button
is held down.
4. With a multispeed blower, repeat steps 1 through 3
for each fan speed.
POWER BOX
WARNING
!
ELECTRIC SHOCK HAZARD.
CAN CAUSE PERSONAL INJURY.
Always turn off power and remove access door
before removing power supply or its cover.
5. If operation is not as described, refer to the Electrical
Troubleshooting section.
The solid-state power supply within the power supply
box can be replaced. When troubleshooting indicates a
power supply or solid-state performance indicator prob-
lem, replace the entire power box or replace the power
supply within the box. See Installation Instructions, form
69-0776. See Fig. 1 for power box removal.

TROUBLESHOOTING PROCEDURE
The electronic air cleaner troubleshooting chart shows
how to quickly isolate a problem in the air cleaner. See
Fig. 4. Although a meter is needed for some steps, the
primary diagnostic tools are the neon light and the test
button.
The following procedures expose hazardous live
parts. Disconnect from power supply between
checks and proceed carefully. These instructions
are for use by only qualified personnel.
