SECONDARY CIRCUIT
IONIZING-COLLECTING CELL
The cells are electrically energized through a contact terminal located at the
top center of each cell. The ionizing wires and alternating collector plates are
electrically charged while the interleaving plates are grounded.
If the space between the charged and grounded plates is bridged with
conductive or semi-conductive material, a short circuit develops. The bridging
or short may be caused by damaged plates, or foreign material lodged
between/on the components. Since the cell should be periodically removed
from the unit to wash away collected dirt, it is susceptible to physical damage.
The cell also contains the ionizing wires, which have been designed due to their
function with minimal structure support and are susceptible to breakage. Short
circuit issues related to dirty or damaged Ionizing-Collecting Cells are readily
identified by the lack of illumination of the Red CELL ENERGIZED light and
quickly identified and isolated by a simple procedure.
To determine if a short circuit condition exists in one or both Ionizing-
Collecting Cell(s), turn the Electronic Air Cleaner OFF. Remove both Ionizer-
Collecting Cells from the cabinet. Re-position the Front Panel Assembly to the
cabinet, turn ON/OFF switch ON and ensure HVAC system blower is operating.
The Green INPUT POWER light should illuminate. If the Red CELL ENERGIZED
light illuminates, an electrical short circuit exists in one or both of the Ionizing-
Collecting Cells. Replace the cells, one at a time, to determine which cell has the
short circuit. The Red CELL ENERGIZED light will not illuminate if a short circuit
condition is detected.
Most short circuit troubles in the cell can be visually detected and corrected.
Refer to COMMON TROUBLESHOOTING TECHNIQUES (pg. 9).
NOTE: The Ionizing-Collecting Cells are not designed for field repair. Ionizing
wires and insulators can be field replaced; however, it is not recommended
that you attempt to replace other cell components (i.e. collecting plates, end
plates, ionizer wire supports).
Troubleshooting

Dusting and “White Dust”
Your new Electronic Air Cleaner will efficiently clean and filter your household air. It will not
eliminate the need for regular dusting of your furniture and belongings. Duct-mounted air
cleaners can only clean air that reaches the air cleaner. Therefore, if the particulates are not
being carried to the air cleaner in the air stream, the air cleaner cannot remove them from your
home.
Occasionally a “white dust” may be noticed in bedrooms or newly furnished rooms. This is
mainly composed of lint which, because it is heavier than other particulates, settles before it
reaches your unit. This “white dust” is not mixed with airborne dirt particles, therefore, it is clean
and has no staining or soiling properties. Running the furnace blower continuously, day and
night, will help reduce this from occurring.
Ozone
Under normal operating conditions, all Electronic Air Cleaners produce minute quantities of
ozone as an incidental by-product. In fact, all electronic products, such as televisions, cordless
telephones and refrigerators, produce some amount of ozone. The average homeowner can
detect the smell of ozone concentrations as low as 25 to 100 ppb (parts per billion). The design
of this unit has been tested and ozone production is approximately half of the published
permissible limits established by the Environmental Protection Agency. These limits recommend
that the concentration of indoor ozone not exceed 50 ppb. Ozone is not harmful in these
concentrations. In fact, the ozone level in major cities can sometimes reach as high as 100 ppb
on a summer day. The addition of optional charcoal after-filters can help reduce the smell of
ozone generated by the air cleaner.
Normally, a new unit will produce more ozone than one that has been in operation for several
weeks. This is due to sharp corners or manufacturing burrs on the Ionizing-Collecting Cell Plates
and is normal. As the Electronic Air Cleaner arcs and zaps, the voltage is vaporizing these areas
and tends to round them off. This is part of the breaking-in period of ownership and the issue
is self-correcting. Also, high-altitude locations can be more susceptible to noticing the presence
of ozone.
An Ionizing-Collecting Cell that has been damaged or bent (the designed spacing between
electrically charged and ground components has been decreased) may also produce an abnormal
amount of ozone.
