CAUTION
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.
These instructions do not cover all variations in systems or provide for every possible contingency. Should
further information be desired or particular problems
arise 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 the
upflow or horizontal right configuration and are fully
convertible to downflow or horizontal left. Refer to Section C beginning on page 3 for additional information.
INSPECTION
Check carefully for any shipping damage. This must be
reported to and claims made against the transportation
company immediately. Check to be sure all major com-

ponents are in the unit. Any missing parts should be reported to your supplier at once, and replaced with authorized parts only.
!
CAUTION
Cardboard packing material must be removed from inside the blower assembly before starting the unit.
Failure to do so may cause indoor blower motor failure.
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.

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 Code of Federal Regulations, Chapter XX, Part 3280
or the equivalent. “SUITABLE FOR MOBILE HOME
USE”
For proper installation the following items must be considered:
1. If adequate power is available and correct according
to nameplate specifications.
2. Insulate all ducts, particularly if unit is located outside 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 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.
5. 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
possible future service.

6. When the air handler with supplementary heater is
to be installed in the downflow position on combustible 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 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 2)
In
addition, ensure that the cabinet is sealed air tight
where the field wires enter the unit.

8. 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.
9. 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.
10. Make sure there are provisions for installing condensate drain lines.
11. If side, front or rear return is required, air handler
must be elevated or placed on a plenum
(TAYPLNM100). Connecting return duct directly to
the side, front or rear of the cabinet is not approved.
12. Route refrigerant & condensate drain lines away
from air handler so they do not interfere with access panels and filters.
13. When external accessories are used, the additional
height and width requirements must be considered
in the overall space needed.
14. These units are not approved for outdoor installation.
15. These units are approved for draw-through application
only.
16. 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.
Steam and Flow-through Fan Power Ductmounted Humidifiers
