Installer’s Guide

6. When the air handler with supplementary heater is

to be installed in the downflow position on combus-
tible flooring an accessory sub-base (TAYBASE100
for 4TEE3F39-64) must be used. See Figure 1.

7. 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 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
American Standard Inc. Only heaters built by American
Standard Inc. are approved for use in the air handler.
These heaters have been designed and tested in accor-
dance 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 fac-
tory approved could cause damage and are not cov-
ered 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 2)

addition, ensure that the cabinet is sealed air tight
where the field wires enter the unit.

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 Code of Federal Regulations, Chapter XX, Part 3280
or the equivalent. “SUITABLE FOR MOBILE HOME
USE”
For proper installation the following items must be con-
sidered:

1. If adequate power is available and correct according

to nameplate specifications.

2. Insulate all ducts, particularly if unit is located out-

side of the conditioned space.

3. Pursuant to Florida Building Code 13-610.2.A.2.1,

this unit meets the criteria for a factory sealed
air handler.

4. 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.

5. 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
possible future service.
