A. GENERAL INFORMATION

THIS INFORMATION IS FOR USE BY INDIVIDUALSHAVING ADEQUATE BACKGROUNDS OF ELECTRICALAND MECHANICAL EXPERIENCE. ANY ATTEMPT TOREPAIR A CENTRAL AIR CONDITIONING PRODUCTMAY RESULT IN PERSONAL INJURY AND/OR PROP-ERTY DAMAGE. THE MANUFACTURER OR SELLERCANNOT BE RESPONSIBLE FOR THE INTERPRETA-TION OF THIS INFORMATION, NOR CAN IT ASSUMEANY LIABILITY IN CONNECTION WITH ITS USE.

To prevent shortening its service life, the air handlershould not be used during the finishing phases of con-struction. The low return air temperatures can lead tothe formation of condensate. Condensate in the pres-ence of chlorides and fluorides from paint, varnish,stains, adhesives, cleaning compounds, and cementcreates a corrosive condition which may cause rapiddeterioration of the cabinet and internal components.

These instructions do not cover all variations in sys-

tems or provide for every possible contingency. Shouldfurther information be desired or particular problemsarise which are not covered sufficiently by this manual,contact your local distributor or the manufacturer as

listed on the air handler nameplate.

These air handlers are shipped from the factory in theupflow or horizontal right configuration and are fullyconvertible 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 bereported to and claims made against the transportationcompany 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 ownerfor the most effective application and satisfaction.These air handlers are suitable for installation in a

closet, alcove or utility room with free, non-ducted, airreturn, using the area space as a return air plenum.With ducted supply air, if the minimum clearances tocombustible materials and service access are observed,the above installations are suitable.

NOTE: CONDENSATION MAY OCCUR ON THE SUR-FACE OF THE AIR HANDLER WHEN INSTALLED IN ANUNCONDITIONED LOCATION. WHEN UNITS ARE IN-STALLED IN UNCONDITIONED SPACES, VERIFY THATALL ELECTRICAL AND REFRIGERANT LINE PEN-ETRATIONS ON THE AIR HANDLER ARE SEALEDCOMPLETELY.

Installer's Guide

This area may also be used for other purposes, includ-

ing an electric hot water heater - but in no case shalla fossil fuel device be installed and!or operated inthe same closet, alcove or utility room.In addition, these air handlers are suitable for installa-

tion in an attic, garage or crawl space with ductedsupply and return air.This equipment has been evaluated in accordance with

the Code of Federal Regulations, Chapter XX, Part 3280or the equivalent. "SUITABLE FOR MOBILE HOMEUSE"

For proper installation the following items must be con-sidered:

1. If adequate power is available and correct according

to nameplate specifications.2. Pursuant to Florida Building Code 13-610.2.A.2.1,

this unit meets the criteria for a factory sealedair handler.

3. Insulate all ducts, particularly if unit is located out-side of the conditioned space.

4. The Refrigerant lines must be sealed and Electri-cal inlets need to be sealed at both the low and

the high voltage.5. To ensure maximum efficiency and system perfor-

mance, the existing supply and return duct systemstatic pressures must not exceed the total availablestatic pressure of the air handler. Reference ACCA

Manual D, Manual S and Manual RS along with theair 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 checkedagainst selected installation site. By noting in ad-vance which knockouts are to be used, proper clear-ance allowances can be made for installation and

possible future service.

7. When the air handler with supplementary heater is

to be installed in the downflow position on combus-tible flooring an accessory sub-base (TAYBASE101for 2/4TEE3F31, TAYBASE100 for 2/4TEE3F37,TAYBASE102 for 2/4TEE3F40- 065) must be used.

See Figure 1.8. If supplementary heat is to be added, power supply

must be sufficient to carry the load. In addition,

minimum air flow settings, unit and duct clearancesto combustible material must be maintained as

stated on the air handler rating nameplate.

[e] [ljll[o]

For air handlers not equipped with a factory installedelectric heater, a field installed heater is available fromTrane. Only heaters built by Trane are approved for usein the air handler. These heaters have been designedand tested in accordance with UL standards to providesafe and reliable operation. A list of approved heatersis provided on the air handler rating nameplate. Heat-ers that are not factory approved could cause damageand are not covered under equipment warranty.

NOTE: If air handler is used WITHOUT a supplementaryelectric heater, a sheetmetal plate is required to coverthe open hole in the airflow system. See Figure 2. Alsoseal the cabinet air tight where the wire enters.

9. 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.If the outdoor unit is to be installed later, or by oth-ers, then installation of the air handler must bemade to allow access for refrigerant lines, or attach

refrigerant lines to air handler when installing.
