GETTING
STARTED
Congratulations for selecting the Resideo Electronic Air Cleaner for your home comfort system! The F300
Electronic Air Cleaner captures and removes a significant amount of the air-borne particles from the air
circulated through the high-efficiency electronic cells. The Electronic Air Cleaner easily mounts in any
position within the return air duct of any gas, oil, and electric forced warm air furnaces and to compressor
cooling up to 5 tons.
When Installing this Product...
1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous
condition.
2. Check the rating given in the instructions and on the product to make sure the product is suitable for your
application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out product operation as provided in these instructions.
How it Works
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 models only: The air then passes through media postfilters, removing additional particles from the air
stream. The air leaving the air cleaner has fewer particles. Each time the air circulates through the electronic
air cleaner, more particles are removed.
What to Expect From Your Resideo Electronic Air Cleaner

GETTING
STARTED
Application Considerations
The Resideo F300 Electronic Air Cleaner is designed to work with gas, oil, and electric forced warm air
furnaces and with compressor cooling. It can also be used with heat pumps if the filter is changed regularly to
prevent excessive pressure drop. The F300 Electronic Air Cleaner is not recommended for applications where
pressure drop may be critical.
Models
F300E: Includes cabinet, access door, solid state power supply, two electronic cells, two metal mesh prefilters,
and two media postfilters.
F300A, B: Includes cabinet, access door, solid state power supply, two electronic cells and two metal mesh
prefilters.
Air Conditioning
Mount the Electronic Air Cleaner upstream of the evaporator coil in a cooling system. The filter will help to
keep the coil clean and reduce maintenance.
Humidifiers
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 is discharged from an atomizing humidifier can overload the air cleaner,
resulting in hard water salts being deposited as dust in the living space.

GETTING
STARTED
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 Resideo Heat Recovery Ventilator or Energy Recovery Ventilator 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.
UV Lights
Germicidal UV lights can cause degradation of the media postfilter. The UV light should be located out of line
of sight or a minimum of 3 feet from the filter. Otherwise the filter may need to be replaced more frequently.

Ducting
The Electronic Air Cleaner is adaptable to all new or
existing forced air heating and cooling systems used
in residential applications. Transitions or turning
vanes may be required in some applications for
effective air cleaner operation.
Transitions
For most efficient air cleaning, spread airflow evenly
across the face of the air cleaner. If the duct is a
different size than the electronic air filter cabinet,
gradual transitions are required. Follow these
guidelines when fabricating:
• Use gradual transitions to reduce air turbulence
and increase efficiency.
• Use no more than 20 degrees (about 4 in. per
running ft. (100 mm per 300 linear mm)) of
expansion on each side of a transition fitting.
Turning Vanes
If the Electronic Air Cleaner is installed next to an
elbow or angle fitting, add turning vanes inside the
angle to distribute airflow more evenly across the
face of the cell.
Offsets
If the duct connection to the furnace in a side
installation allows less than 7 in. (178 mm) for
mounting Electronic Air Cleaner cabinet, attach an
offset to the elbow.

Important Installation Requirements
Personal Safety
• Wear safety glasses while installing the unit.
• Do not cut into any air conditioning or electrical line.
• Follow professional safety standards and all local codes for plumbing, electrical, and mechanical
considerations.
Before Mounting
• Using the figure on the cover and the lists on the inside cover, make sure that you have all the components
for your Resideo Electronic Air Cleaner and the tools to install it.
• Ensure airflow direction through the Resideo Electronic Air Cleaner matches the arrows on the electronic
cell. The arrows should point in the direction of the airflow.
• Choose a location that is readily accessible for checking and cleaning the cells. 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.
• Install the electronic air filter where the temperature will not exceed the ratings in the Specifications.
• Do not mount in the supply air duct.
NOTE: Generally, the best location is in the return air duct next to the blower compartment so the Electronic
Air Cleaner can help to keep the blower motor and evaporator coils clean.
If Replacing an Old Air Cleaner
If the Resideo Electronic Air Cleaner is not identical in size and shape to the existing air cleaner, before
performing a retrofit installation, you might need to add duct transitions to ensure a smooth air flow.
For optimum system performance, clean the cells every six to twelve months (before heating season and
before cooling season). Adjust the schedule to you needs, but clean the cells at least once per year.
NOTE: Before carrying out any cleaning or maintenance activity, the product must be disconnected from the
electricity.
Failure to comply with these requirements will result in voided warranty, improper installation,
and service callbacks.
The Electronic Air Cleaner mounts in any position within the return air duct, usually next to the furnace blower
compartment, but the arrow on the cartridge must point in the same direction as the airflow. See Figs. 18 for
proper location of the Electronic Air Cleaner for a variety of furnace installations.
NOTE: The Electronic Air Cleaner cabinet is sturdy enough to easily support the weight of the furnace and
evaporator coil.

MOUNTING
The following procedure describes a typical side installation on an existing highboy furnace (Fig. 1). Alternate
procedures are noted as appropriate. Other changes in installation procedures may be necessary to complete
your installation.
STEP ONE: Unpack Electronic Air Cleaner
a. Check that all components are included. The electronic air cleaner is shipped assembled. The unit
consists of a galvanized steel cabinet, power supply with OnOff switch and neon light, two electronic
cells, two metal mesh prefilters, two media postfilters (on select models), access door and product data
literature.
STEP TWO: Clean Blower Compartment
a. Remove and discard the existing furnace filter.
b. Thoroughly clean the blower compartment.
c. If possible, power vacuum the ductwork to remove accumulated dust in an existing home, or construction
dirt in a new home. The electronic air cleaner cannot remove dust that has settled in the blower
compartment and distribution ducts.
d. Check the edges of the furnace fan blades for dirt buildup and clean as necessary. The fan will not deliver
the rated cfm if the blades are dirty.
STEP THREE: Fasten the Cabinet to the Furnace
a. Remove and set aside the access door, electronic cells metal
mesh prefilters and media postfilters.
b. Align the cabinet with the return air opening.
c. Create an opening in the furnace to match the cabinet opening.
d. Install a transition when the furnace and air cleaner openings
are different sizes. See Transitions on page 5.
e. Place blocks under the cabinet so the unit is firmly supported
and level. The 5/8 in. (16 mm) mounting foot on the cabinet
hinge plate provides the minimum clearance required for the
access door hinge.
f. Attach the cabinet securely to the furnace. The unit can be
attached directly, as shown, or a starting collar can first be fitted
in the furnace opening. Either drill holes and fasten with sheet
metal screws or rivets, or use slip joints.

MOUNTING
STEP FOUR: Install Turning Vanes
Install turning vanes to help distribute air equally over the full
surface of the upstream side of the air cleaner. Install them
whenever an abrupt 90 degree elbow is installed directly
against the Electronic Air Cleaner cabinet.
STEP FIVE: Fasten Cabinet to Ductwork
Fasten side of cabinet to the ductwork using sheet-metal
screws, rivets, or slip joints, as appropriate.
STEP SIX: Connect Ductwork
a. Connect the vertical duct section to the elbow. If the
vertical drop of the duct is less than 7 in. (178 mm) from
the side of the furnace, shorten the horizontal trunk or
attach an offset fitting to the elbow. See figure to the right.
b. When ductwork is properly aligned, connect the vertical
duct to the horizontal trunk.
STEP SEVEN: 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.
STEP EIGHT: 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:
a. Remove the electronic cell.
b. Remove the screw holding the cell key in place.
c. Turn the key around and place it over the opposite holes.
The tab on the bottom fits into the larger hole, and the
screw fits into the smaller hole. Make sure the arrow on
the key points in the direction of the air flow (downstream).
d. Tighten the screw into the new hole.
e. Insert the electronic cell. The ionizer section will now be on
the air-entering (upstream) side of the cabinet.

installed on the end of the cell closest to the access
door. To install:
a. 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.
b. 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.
c. Insert the divided tab into the square hole.
d. Fold up the wedge and insert it into the divided tab
to lock the handle in place. If necessary, press with
a blunt instrument like the end of a pliers.

b. Insert the metal mesh prefilters on the upstream side of the cabinet in the guide provided.
c. Insert the media postfilters (on select models) on the downstream side of the cabinet in the guide
provided.
d. Replace the access door. Insert the tab on the bottom of 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.
STEP ELEVEN: 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 disconnecting the AFS plug J3 and cutting the R16 jumper on the power supply.
• Plug the electronic air cleaner directly into the correct voltage and frequency outlet. See figure on page 12
for internal schematic. The air cleaner operates correctly with any fan when wired with conduit or plugged
in.

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.
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.
Maintenance
The air cleaner must be cleaned when pressure drop across the air cleaner reaches 0.5 in. w.c. (0.1 kPa), or
at least annually. If the air cleaner is installed downstream from an atomizing humidifier or if the installation
includes both heating and cooling, more frequent replacement may be necessary. Clogged prefilters must be
cleaned promptly to avoid restricting airflow and reducing efficiency of the heatingcooling system. Record
the maintenance date in the space provided on the Electronic Air Cleaner Wash Reminder and Postfilter
Replacement Schedule.

Service
Before cleaning the Electronic Air Cleaner, this must be disconnected from the electricity.
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—twice a year with normal use or more frequently with heavy use.
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: To let the heating or air conditioning system operate normally while the cells are being washed, simply
turn off the air cleaner switch.
Cleaning your Prefilter
1. The quickest and easiest way to clean your prefilter is to use the brush attachment of your vacuum
cleaner to vacuum the lint off the dirty side of the prefilter. Greasy dirt may require soaking the prefilter in
a tub or rinsing with the garden hose. Do not wash the prefilter in the dishwasher or car wash.
2. The prefilter should be cleaned every 6 months or more frequently with heavy use. This will keep the
prefilter clean of air choking lint that can make your system work harder.
