additional information.
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.
5.The area around refrigerant lines must be sealed
and electrical inlets need to be sealed at both the
low and the high voltage.
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. 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.
In addition, these air handlers are suitable for installation in an attic, garage or crawl space with ducted supply and return air.
7. Allow a minimum of 21 inches clearance in front
of the air handler to permit service and removal of
filter.
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.”
8.When air handler with supplementary heater is to
be installed in the downflow position on combustible flooring an accessory subbase (TAYBASE101 for
4TEC3F24-36B or TAYBASE100 for 4TEC3F42B60B) must be used. See Figure 1.
For proper installation the following items must be
considered:
1.If adequate power is available and correct according to nameplate specifications.
9. 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.
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

CAUTION
For air handlers not equipped with a factory installed
electric heater, a field installed heater is available from
Trane. Only heaters built by Trane 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. Also
seal the cabinet air tight where the wire enters.
10.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.
11.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.
12.Make sure there are provisions for installing condensate drain lines.
13.If side, front or rear return is required, air handler must be elevated or placed on a plenum (TAYPLNM100 for 4TEC3F24 - 60B). Connecting return
duct directly to the side, front or rear of the cabinet is not approved.
14. Route refrigerant and condensate drain lines away
from air handler so they do not interfere with access panels and filters.
15.When external accessories are used, the additional
height and width requirements must be considered
in the overall space needed.
16.These units are not approved for outdoor installation.
17.These units are approved for draw-through application only.
NOTE: No atomizing style humidifier is allowed in the
return plenum with the use of this unit.
18. 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.

G. 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 14.
Two secondary drain connections are provided for the
different orientations (See Figure 14). The lower of the
two should be connected as a backup to prevent condensate overflow by a blocked primary drain. The weep
hole in center of drain coupling area should be sealed
with caulk or RTV except in downflow unless secondary drain is connected.
For proper drainage of condensate, the following steps
should be followed:
1.The primary drain line must be trapped with a
minimum of 2" water seal as shown in Figures 15
& 16. Do not use preformed 3/4" PVC running
traps.

4.Do not use reducing fittings in the condensate
drain lines.
5. Slope the drain lines downward a minimum of 1/4"
per foot.
6.Insulate the primary drain to prevent sweating
where dew point temperatures may be met.
7.Provide means for drainage to prevent winter freeze-up of condensate line.
8. Do not connect the drain line to a closed drain system.
9.Use Teflon® tape on the air handler drain line connections! Do Not Use pipe joint compound or PVC/
CPVC cement!
It is always recommended that an auxiliary drain pan
be installed under a horizontally installed air handler.
Connect the auxiliary drain line to a separate drain
line (no trap is needed in this line) and terminate according to local codes.
NOTE: DO NOT use a torch or flame near the plastic
