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.
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.

Eo o) l
|nsta||er's Guide
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:
!.
2.
3.
If adequate power is available and correct according
to nameplate specifications.
Insulate all ducts, particularly if unit is located
outside of the conditioned space.
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. ReferenceACCA
Manual D, Manual S and Manual RS along with the
air handler Product Data and Service Facts for
additional information.
4. It is recommended that the outline drawing be
studied 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.
5. When air handler with supplementary heater is to be
installed in the downflow position on combustible
flooring an accessory subbase (TAYBASE101 for
4TEP3F18-36A, TAYBASE 100 for 4TEP3F42A,
4TEP3F48-63B and TAYBASE102 on 4TEP3F48-63A)
must be used. See Figure 1.
6. 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.
For air handlers not equipped with afactory 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
factory approved could cause damage and are not
covered under equipment warranty.
NOTE:
ff air handier is used WITHOUT a supplementary electric
heater, a sheetmeta] 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.
7. 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.
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 and
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.

|nsta||er's Guide
C. DUCT CONNECTIONS
The supply and return air ducts should be connected to
the unit with flame retardant duct connectors.
Convertible duct flanges are provided on the discharge
opening to provide a "flush fit" for 3/4" or 1-1/2" duct board
applications. See the Outline drawing on page 9 for sizes
of the duct connections. After the duct is secured, seal
around the supply duct to prevent air leakage.
NOTE:
If the convertible duct flanges are not used, they must be
removed and discarded for proper airflow.
D. REFRIGERANT PiPiNG
IMPORTANT:
Refrigerant piping must be routed to maintain service access
to blower compartment and provide easy removal of filter
access panel and filter.
i. Refrigerant connections are made outside the cabinet.
Note:
TXV bulb MUST be protected (wrapped with wet rag) or
removed, while brazing the tubing. Overheating of the
sensing bulb will affect the functional characteristics
and performance of the air handler.

E. CONDENSATE DRAIN PiPiNG
NOTE:
Make certain that the unit has been installed in a level
position to ensure proper draining.
The indoor blower is downstream of the evaporator coil
which creates a negative pressure at the condensate drain
connections during operation. The condensate drain
connections in front of the indoor coil are 3/4" NPT. The
lower connection is the primary drain. See Figure 6.
Two secondary drain connections are provided for the
different orientations (See Figure 6). The lower of the two
should be connected as a backup to prevent condensate
overflow by a blocked primary drain.
For proper drainage of condensate, the following steps
should be followed:
!. The primary drain line must be trapped with a mini-
mum of 2" water seal as shown in Figures 7 & 8. Do
not use preformed 3/4" PVC running traps.
The use of Field fabricated or manufactured traps as
shown in Figures 7 & 8 is acceptable. The manufac-
tured trap shown in Figure 7 allows for a float switch
option to be added.
Refer to the manufacturer's data and instructions
for details.
2. The trap must be located within 4 feet of the air
handler drain outlet connection.
3. It is recommended that a clean-out tee or cross be
installed in the primary drain line for future
maintenance (See Figures 7 & 8).
4. Do not use reducing fittings in the condensate drain
lines.
