See Power Door. 2. Disconnect surge resistor at power supply. 3. Remove screws holding the bus bar. Cell — Plate-type and media-type, Fig. 14. The cell contains the ionizer wires, the ionizer ground plate, Fig. 15, item 1, and the charged and grounded collector plate assembly, item 3, of the plate-type cell. The plate-type and media-type cleaners are the same electrically. Physically, however, while the media-type cell has the same type of ionizer as the plate-type, a fiber glass pad between a charged grid and a grounded grid replaces the charged and grounded collector plate assembly. Fig. 13 — Power Door 31 MM Media Type 31MP Plate Type Fig. 14 — Electronic Air Cleaner Cell DISASSEMBLING THE PLATE-TYPE CELL -Refer to Fig. 15. 1. Remove 4 sheet metal screws, item 8, holding the ionizer ground plate, item 1, to the cell structure, item 2. 2. Lift off the ionizer ground plate. 3. Remove 3 bolts from each end panel. See Fig. 14. 6 4. Remove the cell structure which consists of a riveted assembly of 2 end panels and 2 angles. ROUND INSULATORS, Fig. 15, item 4, may be lifted from the rod ends when the cell structure is removed. 1 — Ionizer Ground Plate 5 — Contact Plate 2 — Cell Structure 6 — Rectangular Ceramic Insulator 3 — Charged and Grounded 7 — Bolts Collector Plate Assembly 8 — Sheet Metal Screws 4 — Round Ceramic Insulator 9 — Bus Bar Fig. 15 — Disassembled Cell, Model 31MP RECTANGULAR INSULATORS, Fig. 15, item 6. 1. Remove the cell structure. See Disassembling the Plate-Type Cell. 2. Remove the large bolt that holds the insulator to the end of the plate assembly. 3. Remove the sheet metal screw holding the insulator and contact plate, item 5, to the end of the bus bar, item 9. 4. Lift off insulator and contact plate. Replacing Ionizer Wires, Fig. 16 — The following procedure is recommended for replacing broken ionizer wires: 1. Remove ionizer ground plate. See Disassembling the Plate-Type Cell. 2. Remove the broken ionizer wire. Be sure no pieces of the broken wire remain in the cell to cause shorting. 3. Secure end of new ionizer wire in loop of bottom ionizer wire spring. 4. Depress top ionizer wire spring with finger as in Fig. 16. 5. Secure top end of ionizer wire in loop of ionizer wire spring while it is depressed. 6. Inspect wire installation and relieve finger pressure from ionizer wire spring. 7. Replace ionizer ground plate.

Energize blower. Cells will dry. Arc Test Button Produces No Snapping Noise Shorted cells Shorted top guide Defective push button Defective surge resistor Defective power supply System blower not operational Humidifier upstream Cells loaded See Troubleshooting Procedure. Energize blower. Unit Snaps or Arcs Continuously Line voltage too high Cells need cleaning Broken ionizer wire Broken contact spring in top guide of power door Broken insulator in cell Broken insulator in power door or contact tray Foreign material lodged between plates or in ionizer Bent plates or media grille for media EAC Broken or deformed arc test button assembly Adjust line voltage. Clean cells. Replace wire. Replace spring. Replace insulator. Replace insulator. Remove object. Straighten. Replace or repair. Humming Noise Improper wiring connections Loose ionizer wires Excessively dirty ionizer or collector Check wiring. Replace or repair. Clean as per Maintenance Instructions, Owner's Manual Air Cleaner Doesn't Clean Dirt Lack of power to cells due to improper alignment of contact spring on power door to cells in top guide Defective interlock plug or receptacle Air volume too great Leaks in ductwork on downstream side of air cleaner Dirty air not being delivered to air cleaner Damaged or improperly placed dirt collecting pad (media-type only) Uneven air distribution across face of unit which may be indicated by uneven loading pattern of dirt in collector section of air cleaning cells The entering air side of collector stage should be evenly covered with dirt. In the case of the 020 sized units, each cell should have an even loading patter...
