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 3

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.
