PLANNING THE INSTALLATION

Application

The F300E Electronic Air Cleaner is used in a forced air heating, cooling, or ventilating system. It removes airborne particles from the air circulated through it. All models have an internal air flow switch that automatically energizes the air cleaner cells when the system blower is on.

Review Installation Requirements

The air cleaner should be installed where all the air passing through the system circulates through it. The best location is in the return air duct next to the blower compartment so the air cleaner can help keep the blower motor and evaporator coils clean.

IMPORTANT
Do not mount in the discharge air duct.
For most efficient air cleaning, airflow must be spread evenly across the face of the air cleaner. If the duct is a different size than the air cleaner cabinet, gradual transitions are recommended. If the duct turns sharply just before the air cleaner, turning vanes are recommended.

Applications with Air Conditioning

The air cleaner should be installed upstream from the evaporator coil. The air cleaner will help keep the coil clean, reducing maintenance.
68-0240EF—3 4
F300E ELECTRONIC AIR CLEANER WITH ENHANCED FILTRATION

Applications with a Humidifier

An evaporative humidifier can be mounted upstream from the air cleaner. An atomizing humidifier should be mounted downstream from the air cleaner, even though hard water salts will be blown into the living space and deposited as dust. If an atomizing humidifier must be mounted upstream from the air cleaner:
1. Mount it as far as possible upstream from the air cleaner.
2. Install a standard disposable furnace filter between the humidifier and the air cleaner to trap water droplets and hard water salts.
3. Frequently clean the air cleaner to prevent a hard water salt buildup.
NOTE: The volume of water that passes through an
atomizing humidifier can overload the air cleaner, resulting in hard water salts being deposited as dust in the living space.

Applications with Outdoor Air Intake

Return air temperature must be at least 40°F (4°C). Lower temperatures can cause ionizer wire failure. If outdoor air is used, warm it upstream from the air cleaner by:
• Making sure the outdoor intake is far enough upstream from the air cleaner so the return and outdoor air is thoroughly mixed. Stratified air can dump a stream of very cold air into one section of the air cleaner.
• Adding baffles upstream from the air cleaner to force thorough air mixing.
• Installing a Honeywell Perfect Window™ Fresh Air Ventilation System that transfers up to 80 percent of the heat from the exhaust air to the incoming outside air. This keeps the incoming air above 40°F (4°C) and reduces energy usage.
• Installing a preheater if large amounts of outdoor air are used. The preheater, which could be an electric strip heater or hot water coil, should be controlled by a thermostat. Hot water or steam coils should be protected by a freeze-up control.

Optional W8600F Air Cleaner Monitor

The W8600F Air Cleaner Monitor can be mounted in the living area or in the furnace room. It should be located in a convenient location to observe the display.
The W8600F Air Cleaner Monitor is furnished with all the connectors needed for easy installation. Follow the installation instructions provided with the W8600F.

Optional W8600A AIRWATCH™ Indicator

The W8600A can be mounted next to the thermostat or in any other location in the living area of the home where the display can be conveniently observed. No wiring is necessary.

Choose Location

Choose a location that is readily accessible for regular inspection and cleaning. Allow at least 13 in. (330 mm) in front of the access door for removing the metal mesh prefilter, media postfilter and electronic cell. Allow enough room above the power supply so it can be serviced without removing pipes, ducts, or other heating system components.
The air cleaner must be installed where the temperature is between 40° to 125°F (4° to 52°C).

Choose Mounting Position

WARNING
Heavy Equipment Hazard. Can cause injury or equipment damage.
Do not mount air cleaner with access door facing down because the latch may not hold and the cell, postfilter and prefilter can fall unexpectedly.
NOTE: Nothing holds the cell, postfilter, and prefilter in place
when the access door is opened.
IMPORTANT
UV light can damage media postfilters. Avoid installing UV lamp downstream of F300 in location where UV light illuminates postfilter.
The air cleaner can be mounted in any position except with the access door facing down. A list of air cleaner mounting positions for a variety of furnace installations follows.
NOTE: At least 13 in. (330 mm) clearance is required
between the access door and any obstructions for cell, postfilter and prefilter maintenance.
— Upflow Highboy furnace: Side installation; air cleaner is
mounted vertically where return enters side inlet of furnace. See Fig. 2A.
— Upflow Highboy furnace: Installation beneath furnace (air
cleaner cabinet can easily support weight of furnace and air conditioner coil). Air cleaner is mounted horizontally where return enters from below. See Fig. 2B.
— Upflow Highboy furnace: Closet installation. Air cleaner is
mounted vertically on furnace between furnace and louvered return air opening in closet door. See Fig. 2C.
— Lowboy furnace: Air cleaner is mounted horizontally in

Determine Duct Design Requirements

The air cleaner is adaptable to all new or existing forced air heating, cooling and ventilating systems used in residential applications. Transitions, turning vanes, or offsets may be needed in some applications for effective operation.
Transitions
Transitions are needed when the duct is a different size than the air cleaner cabinet. Gradual transitions reduce air turbulence and increase efficiency. Limit expansion to no more than 20 degrees or about 4 in. per running foot (100 mm per 300 linear mm) on each side of a transition fitting. See Fig. 3.

4. Tighten the screw into the new hole.
5. Insert the electronic cell. The ionizer section will now be
on the air-entering (upstream) side of the cabinet.

Attach Cell Handles

Cell handles included with the air cleaner must be installed on the end of the cell closest to the access door. To install:
1. Orient the cell as it will be when installed. The gray contact board must be up and the airflow arrow stamped into the cell must point downstream.
2. Hold the handle sideways and insert the solid tab on the back of the handle into the slot in the cell. Turn the handle 90 degrees clockwise to align the divided tab with the square hole. See Fig. 8.

Seal Joints

Seal all joints in the return air system between the air
cleaner and the furnace to prevent dust from entering the clean airstream. Use optional air cleaner cabinet gasket kit (part no. 32002109-001), mastic or foil tape.

Position Cell Key

The electronic cell must always be installed so the ionizer section is on the upstream side. A factory-installed cell key on the bottom of the cabinet allows the cell to be inserted in only one direction. If the arrow molded into the plastic key points in the same direction as the airflow, the ionizer is always on the upstream side.
If position of the key must be reversed, proceed as follows:
1. Remove the electronic cell.
2. Remove the screw holding the cell key in place. See

the door into the slot in the cabinet, then swing it closed and press into place. The door must be firmly in place or the air cleaner will not operate.

Complete Wiring

WARNING
Electric Shock Hazard. Can cause personal injury.
Do not use an extension cord.
• Assure all wiring complies with local codes and ordinances.
• The line voltage power source must match the voltage and frequency printed on the label inside the access door.
• When the System fan comes on, the Air Flow Switch (AFS) senses the negative pressure in the duct and turns on the power supply. If power to the air cleaner is controlled by another switch, the AFS can be disabled by cutting the jumper on the back of the AFS circuit board. See Fig. 9.
Plug the electronic air cleaner directly into the correct
voltage and frequency outlet. See Fig. 9 for internal schematic. The air cleaner operates correctly with any fan when wired with conduit or plugged in.
NOTE: To reduce the risk of electric shock, this product has
a grounding type plug that has a third (grounding) pin. This plug only fits into a grounding type power outlet. If the plug does not fit into the outlet, contact a qualified electrician to install the proper outlet. Do not
change the plug in any way.

Large particles (lint, hair) are caught by the prefilter. As the dirty air passes through the intense high voltage electric field surrounding the ionizer wires, all particles are given an electrical charge.
The air then moves through the collector part of the cell where alternate parallel plates are charged positively and negatively, creating a uniform electrostatic field. The charged particles are attracted to and collect on the plates that have the opposite electrical charge.

F300E ELECTRONIC AIR CLEANER WITH ENHANCED FILTRATION

Check Air Cleaner Operation

With all components in place, turn on air cleaner switch and energize system blower. Check following points of operation:
1. The neon light next to the On-Off switch is on. The neon light shows that the air cleaner is energized and the high voltage power supply is working correctly. If a W8600F is part of the installation, also check the wall panel and make sure the On indicator is lit. The W8600F Fault indicator comes on if there is a problem with the high voltage power supply.
2. Turn off the system blower. The neon light should go off after a few seconds.
3. Turn on the system blower. With the air cleaner ener­gized, push the test button. A snapping sound indicates that the collector voltage is present on the cell.
4. With a multispeed blower, repeat steps 1 through 3 for each fan speed.

SERVICE

CAUTION
Sharp Edges. Can cause personal injury.
Carefully handle the cell(s) or wear protective gloves to avoid cuts from the sharp metal edges.

Cleaning the Cells and Prefilters

To assure optimum performance from the air cleaner, the cells and prefilters must be cleaned regularly and the postfilters replaced regularly—every one to six months. Washing frequency varies, depending on the number of family members, pets, activities (such as cooking or woodworking) and smoking habits. Use the Service Reminder Schedule at the end of this document to help establish and maintain a regular cleaning schedule. Keep your Service Reminder Schedule in a convenient location.
NOTE: Media postfilters should be replaced rather than
cleaned. See Replacing Media Postfilters section.
If the air cleaner has a W8600F Air Cleaner Monitor, the SERVICE indicator activates to indicate filter and cell maintenance are due. The time between activation of the SERVICE indicator is based on air cleaner run time that is selected by the installer at installation.
If the air cleaner has a W8600A AIRWATCH Indicator, the Air Cleaner LCD arrow blinks to indicate it is time to service the cells and prefilters. The time between activations of the Air Cleaner LCD is based on calendar time that is selected at installation.
NOTE: To let the heating or air conditioning system operate
normally while the cells are being washed, simply turn off the air cleaner switch.
IMPORTANT
Vacuum the prefilter or brush or soak it in a tub. Do not wash the prefilter in the dishwasher or car wash.
Automatic Dishwasher
CAUTION
Burn Hazard. Can cause personal injury.
Allow cells to cool completely in dishwasher at end of wash cycle or wear protective gloves to avoid burns. Hot water can accumulate in the tubes supporting collector plates; tip cells so tubes drain.
IMPORTANT
• Check the dishwasher owner's manual. Some manufacturers do not recommend washing electronic cells in their dishwashers.
• If the dishwasher has upper and lower arms, position the cells carefully to allow good water circulation.
• Be careful to avoid damaging the cells when placing them in the dishwasher. Broken ionizer wires or bent collector plates are not included in the warranty.
• Very dirty cells, especially from tobacco or cooking smoke, can discolor the plastic parts and the lining of some dishwashers. This discoloration is not harmful. To minimize it, wash the cells more frequently or try a different brand of detergent.
Do not allow the dishwasher to run through the dry cycle. This bakes on any contaminants not removed during the wash cycle and reduces air cleaner efficiency.
1. Put the cells on the lower rack of the dishwasher with the airflow arrow pointing up. It may be necessary to remove the upper rack. Do not block water flow to the upper arm.
HINT: Lay a few large water glasses between the spikes on
the lower rack and rest the cell(s) on them so the spikes do not damage the aluminum collector blades.
2. Using regular dishwasher detergent, allow the dish­washer to run through the complete wash and rinse cycle. Do not use the dry cycle. To avoid burns, let the cells cool completely before removing, or wear protec­tive gloves when removing the cells. Remember that water may be trapped inside the cells. Tip the cells so the tubes can drain.
3. Wipe ionizer wires and contact board on the end of the cell using thumb and forefinger with a small, damp cloth.
4. Inspect the dishwasher. Rerun wash and/or rinse cycle with the dishwasher empty if there is dirt or residue from washing the cells. If dirt or residue seems excessive, wash cells more often or try a different detergent.

F300E ELECTRONIC AIR CLEANER WITH ENHANCED FILTRATION

Washing Cells in a Container
CAUTION
Hazardous Chemical. Can cause personal injury.
Do not splash detergent solution in eyes. Wear rubber gloves to avoid prolonged detergent contact with skin. Keep detergent and solution out of reach of children.
NOTE: Always wash the cells first, then the prefilters, to
keep heavy prefilter lint from getting caught in the cells.
1. Use a large enough container, such as a laundry tub or trash container, to hold one or both cells.
NOTE: Sharp corners on cells can scratch surface of
bathtub.
2. Dissolve about 3/4 cup of automatic dishwasher deter­gent per cell in enough hot water to cover the cells. If detergent does not dissolve readily, or forms a scum on the water, try another brand, or use softened water
3. After detergent has completely dissolved, place cells in the container and let soak for 15 to 20 minutes. Agitate up and down a few times and remove. See Fig. 12.
7. Wipe ionizer wires and contact board on end of cell using your thumb and forefinger with a small, damp cloth.
Washing Cells at the Car Wash
Use the hand sprayer at a coin-operated do-it-yourself car wash to clean the cells. Hold the nozzle at least two feet away from the unit to avoid damage (such as broken ionizer wires or bent collector plates) from the high pressure stream of water. See Fig. 13. Follow the same sequence of wash and rinse as recommended for cars. However, do not wax the cells. Be sure to rinse until the water draining from the cells no longer feel slippery.

4. Next, wash the prefilters the same way. Empty and rinse
the wash container.
5. Rinse the cells and prefilters with a hard spray of very hot water; rinse the tub clean, then fill the tub with clean hot water and soak for 5 to 15 minutes. Rinse until the water draining from the cells and prefilters no longer feel slippery.
6. Soak cells and prefilters in a final clear water rinse for ten minutes.

Reinstall the Cells and Prefilters
1. Inspect the cells for broken ionizer wires and bent col­lector plates. Repair as necessary or take to a Honeywell Authorized Air Cleaner Repair Station.
2. Slide the prefilters into the upstream prefilter guides.
3. Slide in the air cleaner cells so the airflow arrow points
downstream and the handles faces outward.
4. Firmly close the access door.
5. Turn on the air cleaner. If the cells and prefilters are wet,
the neon light may not come on and you may hear arcing. If the arcing is annoying, simply turn off the air cleaner for two to three hours or until the cells are dry.
Replacing Media Postfilters
To maximize the filtration efficiency of the media postfilters, replace them every six months. Replacement filters are available in the same size and configuration as the original unit. Contact your local Honeywell distributor to purchase replacement filters. Install the replacement filters exactly as the filters provided with the equipment. Use the Service Reminder Schedule at the end of this document to help you establish and maintain a regular replacement schedule. Keep your Service Reminder Schedule in a convenient location.
