Page 4 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.
Page 5: Unit Specifications
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.
Page 6 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.
Page 7 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.
Page 8 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.
Page 9: Replacing The Ionizing Wires
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.
Page 10 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.
Page 11 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.
Page 12: Maintenance Of Your Electronic Air Cleaner
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. More frequent washing (once a month) may be necessary on some installations (new homes for example) where there is new carpeting, plaster dust, or excessive cigarette smoke (Figure 3).
Page 13 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.
Page 14: Common Troubleshooting Techniques
COMMON TROUBLESHOOTING TECHNIQUES SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION Broken or loose ionizing wire(s) Remove broken or loose wire and replace with new wire Dirty ionizing-collector cell Clean as outlined on page 10-11 Rapid arcing or zapping Damaged or bent collector plates Straighten plates with needlenose pliers or replace entire ionizing- collector cell.

Page 19 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.
Page 20 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.
Page 21 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.
Page 22 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.
Page 23 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).

Page 27 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.
Page 28 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.
Page 29 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.
Page 30 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.
