A. GENERAL INFORMATION
THIS INFORMATION IS FOR USE BY INDIVIDUALS
HAVING ADEQUATE BACKGROUNDS OF ELECTRICAL
AND MECHANICAL EXPERIENCE. ANY ATTEMPT TO
REPAIR A CENTRAL AIR CONDITIONING PRODUCT
MAY RESULT IN PERSONAL INJURY AND/OR PROP-
ERTY DAMAGE. THE MANUFACTURER OR SELLER
CANNOT BE RESPONSIBLE FOR THE INTERPRETA-
TION OF THIS INFORMATION, NOR CAN IT ASSUME
ANY LIABILITY IN CONNECTION WITH ITS USE.
To prevent shortening its service life, the air handler
should not be used during the finishing phases of con-
struction. The low return air temperatures can lead to
the formation of condensate. Condensate in the pres-
ence 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.
This unit is equipped with an integrated high efficiency
Whole House Air Cleaner. Careful consideration must
be taken in the installation process to avoid personal in-
jury or equipment damage. These instructions do not
cover all variations in systems or provide for every pos-
sible contingency. Should further information be desired
or particular problems arise which are not covered suffi-
ciently by this manual, contact your local distributor or
the manufacturer as listed on the air handler name-
plate.
These Air Handlers are shipped from the factory in the
upflow or horizontal right configuration and are fully
convertible to downflow or horizontal left. Refer to Sec-
tion C beginning on page 4 for additional information.
INSPECTION
Check carefully for any shipping damage. This must be
reported to and claims made against the transportation
company immediately. Check to be sure all major com-
ponents are in the unit. Any missing parts should be re-
ported to your supplier at once, and replaced with au-
thorized parts only.

INSTALLATION LIMITATIONS& RECOMMENDATIONS
The general location of the air handler is normally se-
lected by the architect, contractor and/or home owner
for the most effective application and satisfaction.
NOTE: Condensation may occur on the surface of the
air handler when installed in an unconditioned loca-
tion. When units are installed in unconditioned spaces,
verify that all electrical and refrigerant line penetrations
on the air handler are sealed completely.
![](asset-2.png)
Installer's Guide
These air handlers are suitable for installation in a
closet, alcove or utility room with free, non-ducted, air
return, using the area space as a return air plenum.
With ducted supply air, if the minimum clearances to
combustible materials and service access are observed,
the above installations are suitable.
This area may also be used for other purposes, includ-
ing an electric hot water heater- but in no case shall
a fossil fuel device be installed and!or operated in
the same closet, alcove or utility room.
In addition, these air handlers are suitable for installa-
tion in an attic, garage or crawl space with ducted sup-
ply and return air.
This equipment has been evaluated in accordance with
the U.S. Department of Housing and Urban Develop-
ment code. Air handler is Suitable for mobile home/
manufactured housing use. Unit is also approved for
modular homes.
For proper installation the following items must be con-
sidered:
1. If adequate power is available and correct according
to nameplate specifications.
2. Prior to unit installation, a heavy gauge steel
plate is attached to the bottom of the unit for
protection during shipping and handling.
Leave this plate in place until the unit is
ready to be connected to ductwork.
3. Insulate all ducts, particularly if unit is located out-
side of the conditioned space.
4. Pursuant to Florida Building Code 13-610.2.A.2.1,
this unit meets the criteria for a factory sealed
air handler.
5. To ensure maximum efficiency and system perfor-
mance, the existing supply and return duct system
static pressures must not exceed the total available
static pressure of the air handler. Reference ACCA
Manual D, Manual S and Manual RS along with the
air handler Product Data and Service Facts for addi-
tional information.
6. It is recommended that the outline drawing be stud-
ied and dimensions properly noted and checked
against selected installation site. By noting in ad-
vance which knockouts are to be used, proper clear-
ance allowances can be made for installation and fu-
ture service.
7. Allow a minimum of 21 inches clearance in front
of the air handler to permit removal of COLLEC-
TION CELL and FIELD CHARGER.
8. Do not install air handler where air cleaner can be
exposed to UV light.
9. When the air handler with supplementary heater is
to be installed in the downflow position on combus-
tible flooring an accessory sub-base (TAYBASE101
for 2/4TEE3D31, TAYBASE100 for 2/4TEE3D37,
TAYBASE102 for 2/4TEE3D40-65) must be used.
See Figure 1.
10. If supplementary heat is to be added, power supply
must be sut_cient to carry the load. In addition,
minimum airflow settings, unit and duct clearances
to combustible material must be maintained as
stated on the air handler rating nameplate.
[o lji o]
For air handlers not equipped with a factory installed
electric heater, a field installed heater is available from
Trane. Only heaters built by Trane are approved for use
in the air handler. These heaters have been designed
and tested in accordance with UL standards to provide
safe and reliable operation. A list of approved heaters
is provided on the air handler rating nameplate. Heat-
ers that are not factory approved could cause damage
and are not covered under equipment warranty.
NOTE: If air handler is used WITHOUT a supplemen-
tary electric heater, a sheetmetal plate is required to
cover the open hole in the airflow system. See Figure
3.

1) FIELD CHARGER - Charges the contaminants
2) COLLECTION CELL - removes and collects very small
impurities from the air.
3) Power Supply - the solid state power supply converts the
24 Volt AC to the high-voltage, direct current required to
power the FIELD CHARGER and COLLECTION CELL.
4) Safety Switch - cuts off all power to the FIELD CHARGER
and COLLECTION CELL when disengaged.
Check carefully for any shipping damage. This must be
reported to and claims made against the transporta-
tion 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.

11. If the unit is installed without a return air duct, ap-
plicable local codes may limit this air handler to in-
stallation only in a single story residence & within
conditioned space.
12. If the outdoor unit is to be installed later, or by oth-
ers, then installation of the air handler must be
made to allow access for refrigerant lines, or attach
refrigerant lines to air handler when installing.
13. Make sure there are provisions for installing con-
densate drain lines.
14. If side, front or rear return is required, air handler
must be elevated or placed on a plenum
(TAYPLNM100 or 101). Connecting return duet di-
rectly to the side, front or rear of the cabinet is not
approved.
15. Route refrigerant & condensate drain lines away
from air handler so they do not interfere with ac-
cess panels and COLLECTION CELL removal.
16. When external accessories are used, the additional
height and width requirements must be considered
in the overall space needed.
17. These units are not approved for outdoor installa-
tion.
18. These units are approved for draw-through application
only.
19. DO NOT use silicon based sealant. This causes a
coating on the FIELD CHARGER pins that will de-
crease the efficiency of the air cleaner.
NOTE: No atomizing style humidifier is allowed in the
return plenum with the use of this unit.
20. Flow-through Bypass Humidifiers
Excessive bypass air may cause water blow-off,
which will adversely affect system operation and air
cleaner performance. To verify bypass airflow, fol-
low the Bypass Humidifier Pre-Installation Cheek-
out and Set-Up Procedures available through your
local distributor. Ask for publication number 18-
CH37D1-1.

mounted Humidifiers
Follow the humidifier installation instructions.
These should only be installed on the supply air
side of the system.
Other Duct Mounted Humidifiers are Not rec-
ommended for installation with the air
cleaner.
21. Unit installation must include either a return air
duet or grill that prevents accidental access to pins.
For upflow open air intake applications that do not
have a grill or return air duet, installation will re-
quire the use of either BAYPLNM120, TASB215,
TA_qB235, or TA_qB260 depending on cabinet size.

electrical knockouts. See Figure 16.
q. After ductwork connections are made, seal air-
tight and per Local codes.
D. DUCT CONNECTIONS
The supply and return air ducts should be connected to
the unit with flame retardant duct connectors. Convert-
ible duct flanges are provided on the discharge opening
to provide a "flush fit" for 3/4" or 1-1/2" duct board appli-
cations, see the Outline drawing on page 20 for sizes of
the duct connections. After the duct is secured, seal
around the supply duct to prevent air leakage.
NOTE: No sheetmetal screws may be used to attach re-
turn ductwork on the side.
NOTE: On units with sheetmetal returns: Return plenum
must be flanged. Sheetmetal screws must be 1/2" in
length or shorter to ensure no contact with air cleaner
or components. Self-tapping screws are supplied with
the unit in the accessory pack. See Figure 17.
NOTE: If the convertible duct flanges are not used, they
must be removed and discarded for proper airflow.
NOTE: Any duct board return connection can be made
to the sides of the unit using tape or mastic.
E, REFRIGERANT PIPING
IMPORTANT:
Refrigerant piping must be routed to maintain service
access to blower compartment and provide easy re-
moval of filter access panel and COLLECTION CELL.
1. Refrigerant connections are made outside the
cabinet.
NOTE: TXV bulb MUST be protected (wrap a wet rag
around the suction line between the TXV bulb and the
braze joint) or removed, while brazing the tubing. Over-
heating of the sensing bulb will affect the functional
characteristics and performance of the air handler.

with caulk or RTV except in downflow unless secondary
drain is connected.
For proper drainage of condensate, the following steps
must be followed:
1. The primary drain line must be trapped with a
minimum of 2" water seal as shown in Figures 22 &
23. Do NOT use preformed 3/4" PVC running
traps.
The use of Field fabricated or manufactured traps
as shown in Figures 22 & 23 is acceptable. The
manufactured trap shown in Figure 22 allows for a
float switch option to be added.
Refer to the float switch manufacturers data and in-
structions for details.
2. The trap must be located within 4 feet of the air
handler drain outlet connection.
3. It is recommended that a clean-out tee or cross be
installed in the primary drain line for future main-
tenance (See Figures 22 & 23).
4. Do not use reducing fittings in the condensate drain
lines.
5. Slope the drain lines downward a minimum of 1/4"
per foot.
6. Insulate the primary drain to prevent sweating
where pipe temperature could meet or fall below
dewpoint temperatures.
7. Provide means for drainage to prevent winter
freeze-up of condensate line.
8. Do not connect the drain line to a closed drain sys-
tem.
9. Use Teflon _'_tape on the air handler drain line con-
nections! Do Not Use pipe joint compound or PVC/
CPVC cement!
It is always recommended that an auxiliary drain pan
be installed under a horizontally installed air handler.
Connect the auxiliary drain line to a separate drain line
(no trap is needed in this line) and terminate according
to National and Local codes.
NOTE: DO NOT use a torch or flame near the plastic
drain pan coupling.
NOTE: DO NOT tighten the drain pipe excessively. Sup-
port the condensate piping and traps outside the unit
to prevent strain on the drain coupling.
