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.  
MOUNT TRANSFORMER  
1. Open access door.  
2. Remove and retain the two screws from the front of  
the power box.  
3. Lift and remove the power box.  
4. Remove and retain the two screws from the sides of

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.
