CHECKOUT
WARNING
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.
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.
3. Turn on the system blower. With the air cleaner
energized, push the test button. A snapping
sound indicates 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.
5. If operation is not as described, refer to the
Electrical Troubleshooting section.
Electrical Troubleshooting
WARNING
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.
TOOLS AND EQUIPMENT
Troubleshooting the electronic air cleaner requires:
• Needle nose pliers for stringing ionizer wires and
inserting edge connectors.
•Test meter.
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.
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.
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.
The solid-state power supply within the power supply
box can be replaced. When troubleshooting indicates
a power supply or solid-state performance indicator
problem, 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.
