SPECIFICATIONS - IMPORTANT THE SPECIFICATIONS GIVEN IN THIS PUBLICATION DO NOT INCLUDE NORMAL MANUFACTURING TOLERANCES. THEREFORE, THIS UNIT MAY NOT MATCH THE LISTED SPECIFICATIONS EXACTLY. ALSO, THIS PRODUCT IS TESTED AND CALIBRATED UNDER CLOSELY CONTROLLED CONDITIONS AND SOME MINOR DIFFERENCES IN PERFORMANCE CAN BE EXPECTED IF THOSE CONDITIONS ARE CHANGED. SPECIFICATIONS Cabinet: 16 gauge welded steel cabinet with a powder coat finish.
PLANNING THE INSTALLATION outdoor air. The Standard recommends as much as 50 CFM per person ventilation air where people are smoking, such as in a cocktail lounge. These recommended outdoor air quantities may be reduced if air cleaning is provided. However, the Standard recommends that “in no case shall the outdoor air quality be less than five CFM per person.” INTRODUCTION Clean air is the subject of numerous laws and regulations.
LOCATION AND POSITION 5. The percent operating efficiency required of the electronic air cleaner. The AutoClean efficiency should be from 85 to 95 percent depending on the application and purpose. See Efficiency Chart, Fig. 3. Because air-handling systems vary greatly in arrangement and style, factors such as location, air distribution, transitions, etc., require careful consideration.
Depending on the installation, it may be necessary to incorporate some or all of the precautions mentioned below: TRANSITIONS When adapting the duct to fit the air cleaner, use gradual transitions in duct size to prevent turbulence and to increase efficiency. 1. Outdoor air intakes should be hooded or louvered to provide adequate protection from rain and snow. The type of hood used will depend upon the installation and expected weather.
ASSEMBLY & INSTALLATION - IMPORTANT This section includes information for the sheet metal, plumbing and electrical installation. Make certain each person involved with the installation is aware of the appropriate subsections in the manual.
c. SHEET METAL INSTALLATION Air Distribution and Ductwork The AutoClean operates most efficiently when all system air is delivered across the electronic cell at a uniform velocity. Turning vanes should be added to any return airdrop upstream from the air cleaner. See Fig. 5. Use caulking compound (not furnished) to seal the flange joints and all ductwork joints on both the inlet and outlet sides. Seal all joints for at least 3 ft. from cabinet. FILTER PLACEMENT 1.

Follow figures 10, 11 12, and 13 for making all the appropriate electrical connections. Figures 10 and 11 are of the internal wiring diagrams for each unit. Figures 12 and 13 are of the total wiring diagrams for the units. Notice the three boxes surrounding the Unit, Timer, and HVAC system. All wires that appear outside of these boxes need to be added by the installer. ELECTRICAL INSTALLATION All wiring must comply with applicable local codes and ordinances.

FIGURE 13 – WIRING SCHEMATIC FOR EXHAUST FAN SYSTEM CHECKOUT 3. Check over the installation for correct sheetmetal, plumbing and electrical work. - IMPORTANT Before putting the AutoClean In-Place Wash Electronic Air Cleaner into service, check through the following items to be sure it is properly installed. 4. Turning vanes should be used in duct elbow to provide even air distribution across the cell. 5.
1. Check for proper orientation of the electronic cells, protective screens and spray shield. Airflow arrows must point downstream. Protective screens must be on both sides of the electronic cells. CHECK THE ELECTRONIC CELLS AND THE POWER SUPPLY 2. Be sure that the electronic cells, protective screens and spray shields are clean, dry and free of foreign objects. Check the indicator light on the power door. It should be on. With the power supply energized, momentarily open the access door.
MAINTENANCE - CAUTION Always disconnect the power to the AutoClean before working on or near the air cleaner. WHEN TO WASH THE ELECTRONIC CELLS While the cells in the electronic air cleaner are being washed, a musty, dirty odor combined with the characteristic odor of the detergent may be noticed. This is caused when the accumulated dirt on the cells is washed off by the detergent and hot water spray. It will disappear after the washing is complete.
REPLENISH THE DETERGENT SUPPLY WASHING THE CELLS OUTSIDE THE ELECTRONIC AIR CLEANER After routine washing, a noticeable buildup may remain on some parts of the cells. This is normal and has only a negligible effect on performance. - IMPORTANT Replenish the detergent supply in the bottle before it is completely empty. If detergent is allowed to dry in the bottom of the hose or bottle, the hose may become plugged.
other short in the charging section, is indicated by the status light on the power door. Broken wires must be replaced. Remove all parts of the broken wire and temporarily use the cell short of one wire until it can be replaced as directed below. See the PARTS LIST to order wires. 2. Soak the cells for the time indicated on the cleaning solution label. Before removing the cells, slosh them around several times. 3. Rinse the cells with a fine spray. 4. Soak the cells and let the water drain.
TROUBLE SHOOTING WARNING! The following instructions are intended for qualified service personnel only. Dangerous line voltage circuits are exposed during this procedure. Disconnect the power before servicing the unit. Voltage may exceed 10,000 Vdc. Make sure meter to be used has appropriate voltage rating. Before beginning this section make sure to review the checkout and maintenance sections! Make sure all wiring is connected properly reference figures 8, 9, 10, and 11.
evaluate cells at no charge and provide free repair estimates. This is highly recommended before untrained personnel attempt repairs. Please contact Air Quality Engineering at 1-800-328-0787 for assistance. Indicator light is NOT on Check to see if the wash system is operating. The indicator light should not be lit when the wash system is activated. Check to see if the cell access door is closed properly.
Too much detergent being used The length of time the detergent pump is on during the wash cycle can be manually changed on the sequence controller by rotating the potentiometer. Mechanical wash system not working (the nozzles are not turning or not traversing along the cells, during the wash and rinse cycle.) The manifold motor operates both the rotation and traversing motion of the jets. Check to see if the manifold motor is operating.
