Remove the access door and slide out mechanical filter. 2. Follow steps 2, 3, 4, 5, 6, 7 and 8 of Installation Procedure in this booklet. 3. Slide mechanical filter into cabinet. Be sure arrow on filter is pointing in the direction of air flow. Secure access door to cabinet with fastener knob. 5 OZONE The odor of ozone may be noticeable during operation of an electronic air cleaner. A somewhat higher ozone generation rate during the first week or 2 of operation may be caused by sharp edges on some of the new high-voltage parts. Normal use dulls these sharp edges in a short time. The odor of ozone is detectable by an average person at levels as low as 0.003 to 0.010 parts per million (ppm). The concentration of ozone produced in a home by an electronic air cleaner ranges from 0.006 to 0.015 ppm. Average concentrations of ozone in the air of major cities range from 0.020 to 0.040 ppm and even higher. This is well above the level produced by an electronic air cleaner. SERVICE Cabinet Assembly, Fig. 2, consists of a power door item 4, which is attached to the cabinet, item 1, by means of a fastener knob, item 5. Inside the cabinet are the prefilter, item 3, and the cell, item 2, both of which can be easily slid out of cabinet for cleaning and service. Power Door, Fig. 13, retains all the air cleaning components inside the cabinet and also contains the power supply, item 1, which produces high voltage for the cells. The power door also contains the surge resistor, item 2, test button, item 7, and the indicator light and ON-OFF switch, item 3. To service these components, remove 6 screws from the ground plate, item 4, on the door and separate ground plate from door. 1 — Power Supply 2 — Surge Resistor 3 — Indicator Light and ON-OFF Switch 4 - 5 - 6 -7 - Ground Plate Receptacle Bus Bar Test Button INDICATOR LIGHT AND ON-OFF SWITCH are both in one unit. Replace complete assembly when necessary. 1. Disassemble power door. See Power Door. 2. Disconnect wires. Mark wires for reassembly. 3. Compress springs holding light/switch assembly in door. 4. Pull assembly from front of door. POWER SUPPLY 1. Disassemble power door. See Power Door. 2. Remove surge resistor connection at the power supply. 3. Remove 4 sheet metal screws holding the power supply to the plate. SURGE RESISTOR is riveted to the bus bar, item 6. The bus bar and surge resistor assembly must be replaced if the surge resistor is defective. 1. Disassemble power door. See Power Door. 2. Disconnect surge resistor at power supply. 3. Remove screws holding the bus bar. Cell — Plate-type and media-type, Fig...
