INTRODUCTION

This Electronic Air Cleaner is a two-stage electrostatic precipitator. The air cleaner is designed to
remove airborne particulates, including dust, dirt, smoke, pollen, virus, spores, bacteria, and
mold from indoor air.

Air movement through the unit is provided by the heating, air conditioning or ventilating system
blower. As dirty air enters the air cleaner, the air passes through Metal Mesh Pre-filters. The Pre­filters prevent lint, pet hair and other large particulates from entering the air cleaner. It is
important that these filters be in place to prevent excessive dirt loading of the air cleaner
Ionizing-Collecting Cells. These filters extend the time interval between scheduled maintenance
of the air cleaner, which allows the Ionizing-Collecting Cells to provide clean air for a longer
period between washings.

The pre-filtered air then passes through a two-stage Electronic Air Cleaner. In the first stage, all
airborne particulate, even submicron size, are electronically charged (positive) as they pass
through the ionizer section. The ionizer field is a result of a corona discharge emanating from
the fine, tightly strung wires suspended between two adjacent flat plates. In the second stage,
the charged particulate passes through an intense electrical field established between
alternately charged and grounded parallel collector plates. Here, the charged (positive)
particulate is attracted to the ground (negative) plates and removed from the air stream.

SECONDARY CIRCUIT POWER SUPPLY

If the Red CELL ENERGIZED light remains out with the Ionizing-Collecting Cells
removed from the cabinet, the power supply is defective. Specific problems in the
Power Tray Assembly can be isolated by using a Multimeter and High Voltage
Probe to check the output voltages.

To check the secondary circuit, a high voltage meter is required. See the section
entitled RECOMMENDED SERVICE TOOLS (pg. 20). To check for proper operation,
it is imperative that the procedure be followed as outlined below:

1. Make sure the HVAC system is operating, the air cleaner ON/OFF switch is
ON, and air cleaner input voltage is correct (120V, 50-60Hz for 120V units and
240V, 50-60Hz for 240V units).

2. Remove Front Panel Assembly from air cleaner.

3. Remove Power Tray Assembly Cover.

4. Check the high voltage contact board assembly for damage or carbon
tracking.

CAUTION:

The cell contacts must be visually checked for corrosion, excessive dirt build-up,
and electrical arc tracking (Carbon path from stainless steel spring to grounded
metal). Clean or replace as required.

5. Replace both Ionizing-Collecting Cells in the air cleaner cabinet.

6. Make test connections from the High Voltage Probe to the Multimeter in
accordance with the probe’s instruction manual. The Multimeter should be
set for reading DC voltage at 20 volt full scale.

7. Attach the High Voltage Probe ground lead to the air cleaner cabinet. While
depressing the safety interlock switch lever, touch the ionizer wire support
with end of the High Voltage Probe. The meter reading should be 6.2 kVDC
+ .2 kVDC.

8. If no voltage is measured, remove the first Ionizing-Collecting cell and check
the second cell by repeating step #7. The meter should read 6.2 kVDC + .2
kVDC.

9. If proper voltage is measured, the first cell is shorted. Refer to COMMON
TROUBLESHOOTING TECHNIQUES (pg. 9).

Cabinet

Mounts to existing ductwork; houses the Ionizing-Collecting Cells and Pre-filters.

Ionizing-Collecting Cells

Collect the dust, dirt and other particulates in the air. They contain the ionizing and collecting
sections. The cells must be installed with the ionizing wires on the air intake side. A spring
contact is located on the top of each cell and must be in the position to make contact with the
contact board assemblies on the bottom of the Power Tray Assembly.

Pre-filters

Trap large particulates before they enter the Ionizing-Collecting Cell.

Power Tray Assembly

Contains the indicating lights, solid-state power supply, contact boards and electrical controls
including the ON/OFF switch and safety interlock switch. A power cord at the rear of the 120 volt
Power Tray allows the unit to be connected to a standard 120 volt outlet. A wiring compartment
is provided on all models at the rear of the Power Tray allowing the option to permanently wire
the unit directly to the HVAC System Control.

Air Flow Sensor (AFS)

Controls the operation of the unit by sensing the movement
of air within the duct. This helps to reduce power usage.

The AFS is designed to provide an efficient and reliable
method of controlling the operation of the air cleaner when
the installer is unable to wire the unit directly into the HVAC
System Blower Control Circuit. The AFS utilizes a thermistor,
which when electrically powered, heats up to approximately
130° F. The AFS stabilizes at this temperature and while the
HVAC System Blower is in operation, air flows through the ductwork, creating a vacuum effect
that pulls cooler air over the hot surface of the thermistor. This air movement cools down the
thermistor which allows the AFS to register that the HVAC System blower is moving air and the
Electronic Air Cleaner must be powered to provide air cleaning.

Air Cleaner Model Identification

The model number and part number for your Electronic Air Cleaner can be found on the data
label located on the inside of the Front Panel Assembly.

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).

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).

Troubleshooting

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. 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 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.
