The F300E Electronic Air Cleaner is a device designed to improve indoor air quality by capturing airborne particles within a forced air heating, cooling, or ventilating system. It is installed in the return air duct and operates when the system blower is on, thanks to an internal airflow switch. The air cleaner is available in four sizes to accommodate various duct dimensions and can adapt to airflow from either side. Its solid-state power supply is self-regulating, ensuring peak efficiency even with varying levels of cell dirt loading. The pressure drop across the air cleaner is comparable to that of a standard fiberglass filter, minimizing impact on system performance.
The F300E operates by first catching large particles like lint and hair in its prefilter. As air then passes through an intense high-voltage electric field created by ionizer wires, all particles receive an electrical charge. These charged particles then move into the collector section of the cell, which features alternating positively and negatively charged parallel plates. The electrostatic field attracts and collects the charged particles onto these plates. Consequently, the air leaving the cleaner contains fewer particles, and this process repeats each time air circulates through the electronic air cleaner, progressively removing more contaminants.
The F300E is adaptable for both new and existing forced air systems in residential applications. For optimal air cleaning, airflow should be evenly distributed across the face of the air cleaner. If the duct size differs from the air cleaner cabinet, gradual transitions are recommended to reduce air turbulence and increase efficiency. For sharp turns in the ductwork just before the air cleaner, turning vanes are suggested to ensure even airflow distribution. If the duct connection to the furnace in a side installation provides less than 7 inches (178 mm) of space for the air cleaner cabinet, an offset can be added to the elbow.
When used with air conditioning, the air cleaner should be installed upstream from the evaporator coil to help keep it clean and reduce maintenance. For humidifiers, an evaporative type can be mounted upstream. However, if an atomizing humidifier is used, it should be mounted downstream to prevent hard water salts from being blown into the living space. If an atomizing humidifier must be upstream, it should be placed as far as possible from the air cleaner, with a standard disposable furnace filter installed between them to trap water droplets and salts, and the air cleaner should be cleaned frequently to prevent buildup.
An activated carbon filter can be used downstream from the air cleaner to remove gaseous contaminants and odors not captured by the electronic air cleaner. It should be placed outside the air cleaner cabinet to prevent combustion risks and ensure carbon granules do not fall into the electronic cell.
For outdoor air intake applications, the return air temperature must be at least 40°F (4°C) to prevent ionizer wire failure. Outdoor air should be thoroughly mixed with return air upstream from the air cleaner, possibly with baffles or a Honeywell Home Ventilation System, or a preheater for large volumes of outdoor air.
The air cleaner can be mounted in any position except with the access door facing down, to prevent the cell and prefilter from falling out unexpectedly. Various mounting positions are suitable for different furnace installations, including side installation for upflow highboy furnaces, beneath the furnace for upflow highboy furnaces, vertically in a closet, horizontally in a return plenum for lowboy furnaces, horizontally in a return duct for downflow counterflow furnaces, and vertically for horizontal furnaces. Multiple air cleaners can be used for high-capacity systems.
The F300E generates a small amount of ozone during normal operation, which may be higher initially due to sharp edges on new high-voltage metal parts. If desired, ozone production can be reduced by installing an activated carbon filter downstream or by adjusting a shorting bar on the power supply, which reduces ozone by 20-25% and efficiency by 7-10%.
Regular inspection and cleaning are crucial for optimal performance. The access door requires at least 13 inches (330 mm) of clearance for easy removal of the prefilter and electronic cell. Sufficient room above the power supply is also needed for servicing without removing other system components.
The cell(s) and prefilter(s) must be cleaned regularly, typically every one to six months, with frequency depending on factors like family size, pets, activities (e.g., cooking, woodworking), and smoking habits. A wash reminder schedule is provided to help maintain regular cleaning.
Cleaning can be done using an automatic dishwasher or by soaking in a container. When using a dishwasher, the cell(s) should be placed on the lower rack with the airflow arrow pointing up, and the dry cycle should be avoided to prevent baking on contaminants. After washing, the cell(s) should be allowed to cool completely or handled with protective gloves, and tipped to drain any trapped water. Ionizer wires and the contact board should be wiped with a damp cloth.
For container washing, a large tub is recommended. Automatic dishwasher detergent should be dissolved in hot water to cover the cell(s), which are then soaked for 15-20 minutes and agitated. Prefilters are washed similarly. Protective gloves are advised to prevent skin contact with the detergent solution.
After cleaning, the cell(s) and prefilter(s) are reinstalled. If they are wet, the neon light may not come on, and arcing might occur; in such cases, the air cleaner should be turned off for two to three hours until dry.
Broken or bent ionizer wires can cause electrical shorts and arcing. Replacement wires with eyelets are supplied for easy installation. The cell should be checked for short circuits using an ohmmeter between the cell frame and both the ionizer and collector contacts; resistance should be infinite.
Optional accessories enhance maintenance and monitoring:
The neon light next to the on-off switch indicates if the air cleaner is powered and if high voltage is present. This light should be on when the system blower is running and off a few seconds after the blower is turned off. If the W8600F is installed, its ON indicator should also be lit, and the FAULT indicator will come on if there's a problem with the high-voltage power supply.
