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 PROPERTY DAMAGE. THE MANUFACTURER OR SELLER
CANNOT BE RESPONSIBLE FOR THE INTERPRETATION 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 construction. The low return air temperatures can lead to
the formation of condensate. 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.

INSTALLATION LIMITATIONS & RECOMMENDATIONS
The general location of the air handler is normally selected 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 location. When units are installed in unconditioned spaces,
verify that all electrical and refrigerant line penetrations
on the air handler are sealed completely.
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, including 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 installation in an attic, garage or crawl space with ducted supply and return air.
This equipment has been evaluated in accordance with
the U.S. Department of Housing and Urban Development 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 considered:
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 outside 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 performance, 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 additional information.
6. It is recommended that the outline drawing be studied and dimensions properly noted and checked
against selected installation site. By noting in advance which knockouts are to be used, proper clearance allowances can be made for installation and future service.
7. Allow a minimum of 21 inches clearance in front
of the air handler to permit removal of COLLECTION 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 combustible 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 sufficient 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.
!
CAUTION
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. Heaters that are not factory approved could cause damage
and are not covered under equipment warranty.
NOTE: If air handler is used WITHOUT a supplementary electric heater, a sheetmetal plate is required to
cover the open hole in the airflow system. See Figure

11. If the unit is installed without a return air duct, applicable local codes may limit this air handler to installation only in a single story residence & within
conditioned space.
12. If the outdoor unit is to be installed later, or by others, 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 condensate 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 duct directly 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 access 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 installation.
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 decrease 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, follow the Bypass Humidifier Pre-Installation Checkout and Set-Up Procedures available through your
local distributor. Ask for publication number 18CH37D1-1.
