INTRODUCTION 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.
UNIT SPECIFICATIONS This air cleaner is easy to install, operate and maintain. Its basic components are the: Cabinet Mounts to existing ductwork; houses the ionizing-collecting cells and prefilters. Ionizing-Collector Cells Collect the dust, dirt and other particulates in the air. They contain the ionizing and collecting sections as described on page 2. The cells must be installed with ionizing wires on the air intake side.
FACTS YOU SHOULD KNOW ABOUT YOUR NEW ELECTRONIC AIR CLEANER Dusting and "White Dust" 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 the air cleaner.
How the Air Flow Sensor Works (available on specific models) The electronic AFS 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 utilizes a thermistor that heats up to approximately 130°F.
High Altitude Operation Because the air is less dense at higher altitudes, there is a possibility of nuisance arcing. The homeowner can quickly and easily correct this condition. 1. Turn the unit OFF. Disconnect cord or turn off circuit breaker. 2. Remove the two screws that secure the cover to the power tray and remove it from the unit. (The entire power supply tray may be removed from the cabinet by removing two screws from inside the cabinet.) Do not lose these screws. 3.
REPLACING THE IONIZING WIRES Ionizing wire breakage is minimal because of the constant tension design and fixed location of the ionizing wire supports. When an ionizing wire breaks, the efficiency of the Electronic Air Cleaner will decrease slightly. However, the unit will continue to operate with broken ionizing wires as long as the broken wires have not caused a short circuit of the unit. Remove all loose and broken wires as soon as they are identified.
Common Questions and Answers Q. Why isn't my air cleaner cleaning my air? A. The air cleaner is most likely working just like it was designed. However, many factors can affect the performance of the unit. Are cold air registers located in the ceiling? If so, it will be difficult for the air flow to carry heavier particulates to the air cleaner. If the dirt doesn't get to the air cleaner, it can't be removed from the air.
Q. What if I no longer hear any popping or zapping noises coming from my unit? Is it still cleaning the air? A. If the zapping noises stop and the air cleaner is not in need of servicing, then one of two situations has occurred. First, the Electronic Air Cleaner has successfully removed all larger particles from the air and is cleaning microscopic particles which do not cause the zapping noise. Second, the blower and/or HVAC system is not running and air is not flowing through the ductwork.
MAINTENANCE OF YOUR ELECTRONIC AIR CLEANER WARNING :Handle ionizing-collector cells with care as plates can be sharp and cause injury if not handled properly. WASHING CELLS AND PREFILTERS Regular washing is necessary to ensure proper performance. A thorough washing once every two months will be adequate for most installations.
To wash cells and prefilter(s) We suggest that you follow the instructions below to properly and thoroughly clean your collector cells. 1. Place enough hot water in a utility tub to cover the first cell. Dissolve 2 to 4 oz. of granulated automatic dishwasher detergent (not laundry detergent) in the water. 2. Allow the cell to soak for 30 minutes. Agitate it up and down in the solution until it appears clean and remove. 3. Repeat with second cell. 4.

PLANNING THE INSTALLATION Application The air cleaners are used in forced 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.
Atomizing Humidifiers If an atomizing humidifier is installed, it must be mounted downstream of the air cleaner. 1. Mount the humidifier as far downstream as possible. It is recommended a distance of at least 10 feet to reduce the possibility of excessive arcing as water droplets pass through the Electronic Air Cleaner. 2. Install a standard disposable furnace filter between the humidifier and the air cleaner to trap water droplets and hard water deposits. 3.
SELECT LOCATION FOR AIR CLEANER Remember to select a location that is readily accessible for periodic inspection and cleaning of this air cleaner. Allow a minimum of 24" clearance in front and 12" clearance above the air cleaner for component removal and service space. For complete dimensions required refer to the section entitled UNIT DIMENSIONS. DIRECTION OF AIR FLOW THROUGH THE AIR CLEANER This air cleaner is set up for left to right air flow when you are facing the access door.
INSTALLATION CAUTION: Only a trained, experienced serviceman should install this electronic air cleaner. The power supply should be removed before installation. To remove the power supply, remove the two (2) screws (See Figure 7) in the top front of the cabinet. Remember to keep this hardware for reinstallation of the power supply when the air cleaner installation is complete. A thorough checkout of the unit installation should be completed before unit operation.
7. Locate the cabinet in the cold air return duct so that all of the return air flows through the unit (Figure 6). If the furnace and air cleaner openings are different, use a transition (Figure 4). 8. Mounting holes are provided for ductwork attachment (Figure 7). The .140" holes are sized for #8 sheet metal screws, or 1/8" rivets. If the adjoining ductwork is flanged, install the screws so that the screw heads are inside the cabinet.

TROUBLESHOOTING • • • • • CAUTION: These procedures should only be attempted by a qualified HVAC technician or electrician. Risk of personal injury could occur by attempting to troubleshoot or repair this unit by untrained persons. Exercise the usual precautions when working with high voltage. When the circuit has been de-energized, always discharge any residual current in the secondary with an insulated handle screwdriver. Always ground power supply and ionizing-collecting cell when bench testing.
PRIMARY CIRCUIT WITH FURNACE BLOWER OPERATING If there is supply line voltage at the connections and no input voltage to the power supply, the outage can be located by checking operation of the safety switch and the interconnecting wiring with a multimeter. Refer to Circuit Diagram, (Figure 9) to check operation of the switches. Following these steps to test for proper operation of the circuit board and power supply assembly: 1.
SECONDARY CIRCUIT IONIZING-COLLECTING CELL The cell is electrically energized through a contact terminal located at the top center of the 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.
CHECKING THE POWER SUPPLY If the output light remains out with the collector cells removed from the cabinet, the power supply is defective. Specific problems on 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. To check for proper operation, it is imperative that the procedure be followed as outlined below: 1.
9. If no voltage is present, remove the second cell. Install cell number one and measure voltage as described above. If voltage is present, the second cell, which is now out of the cabinet, is shorted. Refer to Table 1 on page 12. 10. If no voltage is present, remove both cells and measure the power supply output. While depressing the safety switch, touch the end of the high voltage probe to either the front or rear contact board assembly (Figure 10). The meter should read 6.2 kVDC or higher. 11.
