INTRODUCTION
These instructions cover the installation, operation and
maintenance of an EACB Electronic Air Cleaner
This electronic air cleaner is technically known as 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 a metal mesh prefilter The prefilter prevents 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 collector cells These filters extend the
time between maintenance of the air cleaner collector cells_ This
allows the ionizing-collector cells to provide clean air for a longer
period between washings The prefiltered air then passes through a
two-stage Electronic Air Cleaner In the first stage, all airborne
particulate, even _bmic'ron size, are electronically charged
(,positive) as they pass through the ionizer The ionizer field is set
up by 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 positively charged particulate is attracted
to the negatively ground plates and removed from the air stream

How to Identify Which Air Cleamer Model You Own
The model number and serial number for your Electronic Air
Cleaner can be found on the data label located on the inside of the
access door
Facts You Should Know About Your New
Electronic Air Cleaner
Dus_g and "Whi_usW
Your new Electronic Air Cleaner will efficiently clean and filter
your household air. Unfortunately, it will not eliminate the need for
regular dusting of your furniture and belongings. Due to the design
of all duct-mounted air cleaners, they can only clean the air that
reaches tbe air cleaner.. Therefore, if the particulates are not being
carried to the air cleaner in the air _tream, 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.. However, 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 phones
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 hag been
tested and ozone production is approximately half of the published
permias_le 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 this
Normally, a new unit will produce more ozone than one that has
been in operation for several weeks.. This is due to sharp comers or
manufacturing burrs on the ionizing-conecting ceil(s) and is
normal. As the Electronic Air Cleaner arcs _md 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 Macing between electrically charged and ground
components has been decreased) may also produce an abnormal
amount of ozone_
Hew the .'MrFlow Sensor (AFS) Works
Electronic AFS (see Fig 3) was designed to provide an efficient
and reliable method of controlling the operation of the air cleaner
when the dealer is unable to wire the unit directly into the furnace
blower. The electronic AFS is now integrated into the power
supply circuitry and utilizes a thermistor that heals up to
approximately 130°F (54_C). The AFS then stabilizes at this
temperature and when the furnace blower tams on and air flows
through the ductwork, the same vacuum effect pulls cooler air over
the hot surface. This air movement cools down the thermistor and
this cooling down effect allows the electronic AFS to understand
that the furnace blower is moving air and the Electronic Air
Cleaner must turn on to provide air cleaning
A05029
Fig. 3 - AJrflow Sensor
If the air cleaner is installed in a location that is dusty and dirty, the
sensor on the AFS can become coated with dirt and lint.. This
coating am insulate the AFS and keep it from operating properly
To clean the thermistor, tam unit off and allow thermistor to cool, 1

Planning the Installation
Application
Air cleaners are used in Iorced air heating cooling and ventilating
systems The air cleaner should be installed in the system so that all
the system air is circulated through the air cleaner The air cleaner
will only remove the airborne contaminants delivered to it,
Maximum performance is obtained when the system blower is set
for continuous operation
Installation Requirements
The best location for the air cleaner is in the return air duct next to
the blower compartment, In this location, the blower molor and
cooling coils will be kept clean.
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this caution may result in reduced airflow
and potential operating problems
a o not install the air cleaner in the diseharge air duct
Before instaning the air cleaner, consider the application and type
of e VAC sy_em present, See Fig, 7 for the most common types, If
a transition between the ductwork and air cleaner is required, refer
to section entitled Transitions and Fig 5,, The unit must be readily
access_le for periodic inspection and cleaning of the prefilters and
electronic cells to maintain maximum efficiency and trouble-free
operation,
Air Conditioning
The air cleaner should be installed upstream of the cooling coil
This will keep the coil clean and reduce air conditioning coil
maintenance Improved cooling efficiency is the result and directly
affects energy costs A clean coil will reduce utility costs.
Humidifiers
An evaporative humidifier can be mounted upstream of the air
ctcanem, It is best to install an atomizing humidifier downstream of
the air cleaner because hard water salt deposiL_ and water droplets
may damage the air cleaner
