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

AirFlow Sensor (AFS)

This part controls the operation of the unit by sensing the

movement of air within the duct This helps to reduce power usage. 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 then take a cotton swab dipped in rubbing alcohol and carefully insert it into the hole tocaled on the right hand side of the power S[2dqt_sl-p E_ (whhn ll2_ing thHunit)ThHho_liS 3/I6" (5 p p ) in diameter and is located on the front of the power tray assembly.. Carefully twirl the cotton swab between your fingers, making sore the tip is lightly in contact with the coated bead, cleaning this

coating from the thermistor If airflow sensor is bypa_ed on the circuit board, the Air Cleaner will run at all times when power is

applied (see Fig 4),

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
