Secondary Circuit - Ionizing-Collecting Cells
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 cells
should be periodically removed from the unit to wash away collected dirt, it is susceptible to
physical damage. The cells also contain 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 (page 9).
Notice: 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).

Operation

Regular 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. Operating the HVAC system 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 high
voltage is vaporizing these areas and tends to round them off. This is part of the breaking-
in period 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.
