10.If no voltage is present, remove the second cell. Install cell number one and measure voltage as described in step #7. If voltage is present, the second cell, which is now out of the cabinet, is shorted. Refer to COMMON TROUBLESHOOTING TECHNIQUES (pg. 9).

11.If no voltage is present, remove both Ionizing- Collecting Cells and measure the power supply output. While depressing the safety interlock switch lever, touch the end of the high voltage probe to either the front or rear contact board assembly. The meter should read 6.2 KVDC or higher.

12.If no voltage is present, check the transformer. Set the Multimeter for reading AC voltage at 200 volt full scale and attach meter test leads to the junction of the transformer secondary leads and the circuit board. The meter should read 24 volts +/– 4 volts.

13.If there is no voltage from the transformer, replace the transformer and power supply board.

Introduction

INTRODUCTION

This Electronic Air Cleaner is 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 Metal Mesh Pre-filters. The Pre- filters prevent lint, pet hair and other large particulates from entering the air cleaner. It is important that these filters be in place to prevent excessive dirt loading of the air cleaner Ionizing-Collecting Cells. These filters extend the time interval between scheduled maintenance of the air cleaner, which allows the Ionizing-Collecting Cells to provide clean air for a longer period between washings.

The pre-filtered air then passes through a two-stage Electronic Air Cleaner. In the first stage, all airborne particulate, even submicron size, are electronically charged (positive) as they pass through the ionizer section. The ionizer field is a result of a corona discharge emanating from the fine, tightly strung wires suspended between two adjacent flat plates. In the second stage, the charged particulate passes through an intense electrical field established between alternately charged and grounded parallel collector plates. Here, the charged (positive) particulate is attracted to the ground (negative) plates and removed from the air stream.
