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.
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.

|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.

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.

In addition, these air handlers are suitable for installation
in an attic, garage or crawl space with ducted supply and
return air.

Eo o)

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.

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
considered:
!.

the following items must be

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.

NOTE:

3. 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. ReferenceACCA
Manual D, Manual S and Manual RS along with the
air handler Product Data and Service Facts for
additional information.

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, minimum air flow settings, unit and duct clearances to
combustibles must be maintained
as stated on the
air handler rating nameplate.

4. 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.

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.

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.

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.

must be elevated or placed on a plenum (TAYPLNM100
or 101). Connecting return duct directly to the side,
front or rear of the cabinet is not approved.
12. Route refrigerant and 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
the overall space needed.

e. Pedestal and unit should be isolated from the
foundation using a suitable isolating material.

c. Detach the coil from the drain pan by removing
4 screws as shown in Figure 4.

f. Cage

nuts are not provided
for horizontal
left
suspension.
However, if the unit is suspended,
it
must be supported
from the bottom near both ends
as well as the middle to prevent sagging. The
service access must remain unobstructed.

d. Remove the front triangular baffle from the coil
and install the 1/2" wide gasket provided per
Figure 4. Trim the gasket length to fit the baffle.
Reinstall the bane to coil, with gasket material
compressed against the coil.
e. Install the water blow-offbaffles provided on each
side of the coil with the flange at the top as shown
in Figure 4. The bottom of the baffle is to be as
close to the bottom of the coil as possible.
f. Install the 7/8" wide gasket in each side of the
drain pan as shown in Figure 4 (sect. X-X).

g. It is always recommended that an auxiliary drain
pan be installed under a horizontal air handler
(See Condensate Piping) to prevent possible
damage to ceilings.
h. Isolate the auxiliary drain pan from the unit or
from the structure.

h. The unit is then placed with the blower side down
and the coil is replaced on the coil channel supports
with the drain connections at the bottom. The unit
is now in downflow position with front access.

HORIZONTAL RIGHT
a. For maximum
e_iciency
and Customer ease of
filter maintenance, it is recommended that a
properly sized remote filter grille be installed for
horizontal applications. Airflow should not exceed
the face velocity of the filter being used. The
factory installed filter should then be removed from the unit.

HORIZONTAL LEFT
a. For maximum
efficiency
and Customer ease of
filter maintenance, it is recommended that a
properly sized remote filter and grille be installed
for horizontal applications. Airflow should not
exceed the face velocity of the filter being used.
The factory installed filter should then be
removed from the unit.
b. To convert the unit to horizontal left, front access,
slide the coil out on the coil channel supports and
rotate the complete coil 180 degrees.
c. Remove the factory installed bane assembly from
the apex of the coil by removing the 5/16" hex head
screws. Replace this baffle with the factory supplied narrow coil bane using the screws removed
previously (See Figure 3).
d. The coil is then inserted back into the cabinet on
the opposite side coil channel supports. The unit is
now horizontal left with front access.
e. Openings

baffle which fits the inner edge of the drain pan
with RTV type adhesive/sealant
before installing

not required.
c. The unit is designed for suspension using 1/4" 20 threaded rods. Other means of suspension are
allowed as long as the unit is supported from both
ends as well as the middle to prevent sagging and
service access is not obstructed.

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
