Installer’s Guide
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
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 (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 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
.
Also
seal the cabinet air tight where the wire enters.
9. If field installed electric heaters are applied, mini-
mum air flow settings, unit and duct clearances to
combustibles must be maintained as stated on the
air handler rating nameplate.
10. 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.

NOTE: CONDENSATION MAY OCCUR ON THE SUR-
FACE OF THE AIR HANDLER WHEN INSTALLED IN AN
UNCONDITIONED LOCATION. WHEN UNITS ARE IN-
STALLED IN UNCONDITIONED SPACES, VERIFY THAT
ALL ELECTRICAL AND REFRIGERANT LINE PEN-
ETRATIONS ON THE AIR HANDLER ARE SEALED
COMPLETELY.
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. Pursuant to Florida Building Code 13-610.2.A.2.1,
this unit meets the criteria for a factory sealed
air 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 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.
