INSTALLATION, LOCATION & LIMITATIONS
NOTE: Do not install the air filter in the discharge air
stream of either the heating or cooling unit.
This air cleaner cabinet must be mounted in the return air duct of
a central forced-air furnace/air handler.
Select a location that meets the following:
1. The face of the cell must be at a right angle to the air stream.
2. Allow a minimum of 28 inches clearance in front of the air
cleaner to permit removal of cells and pre-filter.
3. Flow-through Bypass Humidifiers
Excessive bypass air may cause water blow-off, which will
adversely affect system operation andAir Cleaner perfor-
mance. To verify bypass airflow, follow the Bypass Humidi-
fier Pre-Installation Checkout and Set-Up Procedures
available through your local distributor. Ask for publication
number 18-CH37D1-1.
4. Steam and Flow-through Fan Power Duct-mounted Hu-
midifiers
Follow the humidifier installation instructions. These
should only be installed on the supply air side of the
system.
UnpacktheAirCleaner andcheck tomake sureall compo-
nents are included. They consist of:
1) PRE-FILTER - traps large particles such as hair and lint
before they can enter the COLLECTION CELL section.
2) FIELD CHARGER - Charges the contaminants
3) COLLECTION CELL (2) - removes and collects small
impurities from the air.
4) Filter Mount Rail (2) - mounts into existing cabinet and is
used to hold the components in place. Rail is also used
to activate the safety power switch.
5) Power Door -the solid state power supply components
that convert the 24 Volt AC to the high-voltage, direct
current required to power the FIELD CHARGER and
COLLECTION CELLS. Allows access to the fluted
COLLECTION CELLS, FIELD CHARGER and PRE-
FILTER.
6) Transformer - supplies 24 Volts to the indoor unit and air
cleaner
7) 24 Volt Power / Control Cable
8) Gasket, Literature and Hardware Packet
9) Template, Screws and Drill Bit Kit - used to mount rails
10) Insulator Film
Check carefully for any shipping damage. This must
be reported to and claims made against the trans-
portation company immediately. Check to be sure
all major components are in the unit. Any missing
parts should be reported to your supplier at once,
and replaced with authorized parts only.

NOTE: Do NOT use a silicon base sealant. This causes a
coating on the FIELD CHARGER pins that will decrease the
efficiency of the air cleaner.
Note: Dual Circuited Air Handlers matched with heat pumps
will require an accessory Wall Mounted Transformer KIT #
BAYTRANS12024A to power the air cleaner. Do not replace
air handler transformer with the transformer supplied with
the air cleaner.
TFE Models only - Remove Existing Electrical
Hardware:
Identify the existing air cleaner located in the
return air duct of a central forced-air furnace/air
handler. The air cleaner is typically installed as
shown in Figures 2 or 3 on the previous page.
Furnace and Air Handler – (120VAC models) If the
existing air cleaner is an electronic type Perfect Fit
filter (EAC), switch the POWER button to the
“OFF” position. All furnace applications, and some
air handler applications use 120VAC 3 prong power
cord. This should be unplugged from the electrical
outlet.
Air Handler – (240 VAC models) If the EAC is
internally wired into the air handler, the power cord
and polarized connector adapter will need to be
removed from the air handler system.
1. Disconnect the strain relief connector (see
Figure 4 to the right).
2. Remove the six pin polarized connector on
the adapter located between the female
polarized connector on the heater and the
male polarized connector from the air handler
control box. See Figure 4 to the right.
3. Reconnect the female polarized connector on
the heater and the male polarized connector
from the air handler control box.
4. Disconnect the green ground wire on the plug
adapter from the heater barrier.
5. Seal the knockout used by the previous
power wires.
Strain relief
Disconnect green ground
lead from adapter from the
air handler cabinet ground.
Disconnect plug from heater. If no
accessory heater was installed,
disconnect this plug from the polorized
connector mounted on the electrical
junction box.
Figure 4. TFE wiring
For Non-TFE models, skip the section below and go to the
next page.
CAUTION
!
Do not install air cleaner where the filter can be exposed to
UV light. UV light can cause the plastic material to deterio-
rate, which may lead to filter damage.
5. Other Duct Mounted Humidifiers
Not recommended for installation with the air cleaner.
DO NOT operate the air cleaner during construction of a home.
The air cleaner is designed for use in normal living conditions
to capture small particles. The volume of dust and condensate
in the presence of chlorides and fluorides from paint, varnish,
stains, adhesives, cleaning compounds, and cement creates a
corrosive condition which may cause rapid deterioration of the
cabinet and internal components of the air cleaner and the
heater/furnace.
▲WARNING
!
Disconnect ALL power to the indoor air handler, fur-
nace, and air cleaner. NOTE: There may be more than
one electrical disconnect switch. Electric shock can
cause personal injury or death.

4. Leaving the template in place to prevent the drill bit
from “walking”, use the provided drill bit to drill two holes
in the air cleaner enclosure. Do not try to mark and then
drill the holes, because the drill bit will have the
tendency to “walk” on the flat sheet metal case. This will
cause the metal rail to be installed incorrectly.
5. Use the provided screws to fasten the rail into place.
The metal tabs on the rails should be facing the front of
the air cleaner enclosure. After installed, one of the tabs
will be flush with the front of the enclosure and the other
will extend past the front edge of the enclosure.
6. With the rail now firmly affixed to the air cleaner
case with two screws, it may be desirable to add an
optional third screw on the rail for extra support. A third
hole is provided for this purpose, as well as a screw.
Use the existing hole located in the center of the rail as
a guide much like the installation template was used
earlier to prevent the drill bit from walking.

DISPLAY FEATURES (Fig. 14)
The air cleaner display can be used for several functions:
• Provide the homeowner the operating status of the air
cleaner, including an indication the PRE-FILTER or
COLLECTION CELLS need cleaning.
• The installer accesses the Set-Up Mode to change the
time to clean settings for the PRE-FILTER and
COLLECTION CELLS as well as change the power level
setting.
• The unit will display fault codes for the homeowner
indicating there is a problem with the air cleaner and
various fault codes for the service technician to assist in
troubleshooting the problem.
AIR CLEANER OPERATION
Turn the air cleaner on by pushing the POWER button. The
backlit POWER and Filter RESET buttons will illuminate
along with the first green LED (G1) indicating 24 volt power
is present to the air cleaner.
When the indoor fan is operating the first LED (G1) will
slowly flash. This indicates the FIELD CHARGER and
COLLECTION CELLS have power and the unit is operating
normally. There is a slight time delay between the indoor fan
starting and LED (G1) flashing.
In normal operation, the air cleaner makes a slight sound as
the air passes through it and is cleaned. In some
applications, you may notice this sound coming from the
return air vent(s). If desired, this sound level can be
reduced with minimal impact on air cleaning efficiency by
reducing the power setting of the FIELD CHARGER in the
Set-Up Mode, see page 8.
NOTE: There is a 10 minute delay after the indoor fan
operates, before the air cleaner starts to operate, each
time the power to the air cleaner is turned off/on. This can
be bypassed by going into and then out of the Set-Up
mode
SET-UP MODE
A combination of RED, YELLOW, and GREEN LED's are
used to indicate the following settings.
• The three GREEN LED's are used to indicate PRE-FILTER
cleaning interval. This is measured in actual run time of the
indoor fan. The default setting is 2 months.
• The four YELLOW LED's indicate the collection cell
cleaning interval. This is measured in actual run time of the
indoor fan. The default setting is 6 months.
• The three RED LED's indicate the power level setting. The
default is maximum.
SET-UP MODE OF OPERATION
To enter the Set-Up Mode press and hold both the POWER
and RESET buttons for a minimum of 5 seconds. The current
settings are then displayed. See Fig. 15 If this is the desired
setting or at any time you want to exit the Set-Up mode,

FIELD CHARGER POWER LEVEL
The RED LED lights are used to set the power level of the
FIELD CHARGER for maximum, medium, or minimum. The
number of illuminated RED LED lights indicates the current
setting. The factory setting is for maximum.
Lower settings will reduce the slight sound emitted by the
unit with minimal loss of air cleaning efficiency, if desired.
Lower settings will also further reduce the very low ozone
produced by the air cleaner. The U.S. Food and Drug
Administration recommends indoor ozone concentrations
should not exceed 50 parts per billion. Your air cleaner will
contribute only 5 parts per billion at the factory setting and
can be reduced to 3 parts per billion at the minimum setting.
FIELD CHARGER POWER LEVEL SETTINGS
One or more of the RED LED lights will illuminate. To
change the power level setting, press the RESET button
until the desired setting is indicated.
To save your new settings and exit the Set-Up mode, press

MAINTENANCE
For maximum efficiency the COLLECTION CELLS and PRE-
FILTER should be inspected and cleaned on a regular basis.
The FIELD CHARGER should only be removed and cleaned
annually by an authorized service professional.
CAUTION
!
High Voltage is present within the air cleaner for operation.
Beforeremovingthedoor,turnthepoweroffandwaitatleast
15 seconds to allow voltage to discharge.
NOTE: Before cleaning the coil or ducts in the air handler
or furnace, remove the COLLECTION CELLS, FIELD
CHARGER, and PRE-FILTER from the air cleaner.
Chemicals used during the cleaning of the air handler,

1. Turn the air conditioning system off at the thermostat.
2. Turn off power to the air cleaner by pushing and holding the
POWERbuttonforthreeseconds. TheLED'swillremainon
until the voltage has discharged and it is safe to remove the
door. This requires approximately 15 seconds. Do not
remove the door until all lights are off.
3. Disconnect the power/control cable if required to place the
door in a secure location.
PRE-FILTER CLEANING
The PRE-FILTER can be vacuumed or washed to clean. The
PRE-FILTER should be completely dry before re-installing.
NOTE: Do not replace the plastic PRE-FILTER with a metal
type PRE-FILTER. A metal PRE-FILTER will cause
reduction in efficiency and potential failure of the
electronics in the air cleaner
COLLECTION CELL CLEANING
The COLLECTION CELLS can be cleaned either by
vacuuming (recommended method) or by washing.
VACUUM CLEANING
Vacuum both sides of the COLLECTION CELLS to clean.
WASHING
Use low-pressure water spray, such as a sink sprayer or
garden hose to clean the cells. Some residue may require
warm water to be removed.
• DO NOT USE SOAP OR DETERGENT IN CLEANING THE
COLLECTION CELLS.
• DO NOT IMMERSE THE CELLS COMPLETELY IN WATER.
• DO NOT PLACE THE CELLS INTO A DISHWASHER TO
CLEAN .
Slightly tap the COLLECTION CELLS to remove water
retained in the filter. Allow the COLLECTION CELLS to dry
before re-installing.
