    - smoke and bacteria, to name a few, are microscopic in size. Polluted air enters the unit through the front of the air cleaner. The fan pulls in dirty air and the pre-filter traps large particles (hair, lint, etc.). The smaller particles (dust, smoke, pollen) in the dirty air receive a positive electrical charge as they pass through the ionizing section.

  • Page 5: Troubleshooting Guide

    Warning: The troubleshooting portion of this manual requires that the unit power be “ON” for much of the servicing portion of troubleshooting. When working on the unit under power, use all of the standard precautions in working with any electro-mechanical device that contains line voltage, high voltage, and rotating elements.
  • Page 6 How to Remove the Power Supply Cover Insert flathead screwdriver into slot on the interior edge of the power supply cover, and push plastic clip away from contact wall so that the cover can be lifted up. The switch wires will limit the movement of the power supply cover. Is the switch actuator broken? Is the switch properly seated in the bracket, or is the bracket broken or distorted? The switch is held in position by a bracket that allows the switch to be snapped...
  • Page 7 Check the voltage to and from the switch when activated. You should be able to measure line voltage entering and leaving the switch when activated. Check the switch plate cover. The plate must sit squarely on the bearing wall and the cabinet base. 2.
  • Page 8 c. If the light does not operate with the cell removed, check the wires to the light and confirm that they are properly connected. Check the voltage from the light terminals on the power supply board. Set meter to appropriate scale. You should have about 16 volts DC.
  • Page 9 e. Check the input voltage to the transformer using a standard lead and a multimeter. Check the voltage from the black lead on the terminal L speed control switch and white lead on power supply board labeled line neutral. Activate the interlock switch. The meter should indicate line voltage.
  • Page 10 d. If there are no signs of distortion, remove the blower wheel (see: Blower Wheel Removal) and activate the unit. Notice if the motor shaft rotates without the blower wheel. If the motor shaft operates, the problem is related to the blower wheel. 4.
  • Page 11 c. Check to see if the blower wheel is adequately supported by the outside bearing plate assembly. d. Check to see if the motor mounting bracket snap tabs are in place or are loose. Look into the four base slots to see the tabs. e.
  • Page 12 If the cell is arcing, check the following: a. If there are loose or broken ionizer wires. b. If the cell is dirty. Remove the cell and wash with warm soapy water. Dry completely before re-installing. c. If there are bent cell plates. d.
  • Page 13 If the H.V. contacts are not properly aligned or the contact wall is not properly aligned. 7. Checking for ionizing needle operation. Using HV voltage probe check needle for high voltage -5.5 KVDC to -7.0 KVDC. a. If voltage is present, the ionizer is OK. b.
