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.

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.

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 future service.
7. Allow a minimum
of 21 inches clearance
in front
of the air handler to permit removal of COLLECTION CELL and FIELD CHARGER.
8. Do not install air handler where air cleaner can be
exposed to UV light.
9. When the air handler with supplementary
heater is
to be installed in the downflow position on combustible flooring an accessory sub-base (TAYBASE101
for 2/4TEE3D31,
TAYBASE100 for 2/4TEE3D37,
TAYBASE102 for 2/4TEE3D40-65)
must be used.
See Figure 1.
10. If supplementary
heat is to be added, power supply
must be sut_cient
to carry the load. In addition,
minimum airflow settings, unit and duct clearances
to combustible
material
must be maintained
as

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 U.S. Department
of Housing and Urban Development code. Air handler is Suitable for mobile home/
manufactured
housing use. Unit is also approved for
modular homes.
For proper installation the following items must be considered:
1. If adequate power is available and correct according
to nameplate
specifications.
2. Prior to unit installation,
a heavy gauge steel
plate is attached
to the bottom of the unit for
protection
during
shipping
and
handling.
Leave
this plate
in place
until the unit
is
ready to be connected
to ductwork.
3. Insulate all ducts, particularly
if unit is located outside of the conditioned space.
4. Pursuant
to Florida Building Code 13-610.2.A.2.1,

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.

5. 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.

2) COLLECTION CELL - removes and collects very small
impurities from the air.
3) Power Supply - the solid state power supply converts the
24 Volt AC to the high-voltage, direct current required to
power the FIELD CHARGER and COLLECTION CELL.
4) Safety Switch - cuts off all power to the FIELD CHARGER
and COLLECTION CELL when disengaged.
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
components are in the unit. Any missing parts should
be reported to your supplier at once, and replaced with

11. 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.
12. 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.
13. Make sure there are provisions for installing condensate drain lines.
14. If side, front or rear return is required, air handler
must
be elevated
or placed
on a plenum
(TAYPLNM100 or 101). Connecting return duet directly to the side, front or rear of the cabinet is not
approved.

18-GE10D1-4

15. Route refrigerant
& condensate
drain lines away
from air handler so they do not interfere with access panels and COLLECTION
CELL removal.
16. When external accessories are used, the additional
height and width requirements
must be considered
in the overall space needed.
17. These units are not approved for outdoor installation.
18. These units are approved for draw-through application
only.
19. DO NOT use silicon based sealant. This causes a
coating on the FIELD CHARGER pins that will decrease the efficiency of the air cleaner.
NOTE: No atomizing style humidifier is allowed in the
return plenum with the use of this unit.
20. 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
Cheekout and Set-Up Procedures
available through your
local distributor.

J. AIRFLOW

ADJUSTMENT

Disconnect power to the air handler before changing
dip switch positions.
Failure to follow this procedure may result in equipment damage.
Blower speed changes are made on the ECM Fan Control mounted inside the control box. The ECM Fan Control controls the variable speed motor.
There is a bank of 8 dip switches (See Figure 24). The
dip switches work in pairs to match the airflow for the
outdoor unit size (tons), cooling airflow adjustment,
Fan
off-delay options, and heating airflow adjustment.
The
switches appear as shown in Figure 25.
If the airflow needs to be increased or decreased, see
the Airflow Label on the air handler or the Blower Performance Table in the Service Facts. Information
on
changing the speed of the blower motor for your specific
outdoor model size is in the Blower Performance Table.
Be sure to set the airflow for the correct tonnage.
Refer to blower housing for correct setting.

from the air cleaner.
Chemicals
used during
the
cleaning of the air handler or ductwork can damage the
air cleaner components and degrade the performance
of the air cleaner.

PROCEDURE

NOTE: In normal operation,
the air cleaner makes a
slight sound as the air passes through and is cleaned.
In some applications, you may notice this sound coming from the return air vent(s). If desired, this sound
level can be reduced with minimal impact on air cleaning efficiency
by reducing
the power setting of the
FIELD CHARGER.
The unit is shipped with the power
set at 9.6KV (high). If sound is heard, reduce power
level to 8.0KV (low) at the switch on the power supply.
See Figure 27.
