Introduction
Read this manual thoroughly before operating or
servicing this unit
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required Your personal safety and the proper
operation of this machine depend upon the strict
observance of these precautions
The three types of advisories are defined as follows:
Indicates a potentially hazardous situation
which, if not avoided, could result in death or
serious injury.
Indicates a potentially hazardous situation
which, if not avoided, could result in minor or
moderate injury. It could also be used to alert
against unsafe practices.
Indicates a situation that could result in
equipment or property-damage only
accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere In particular, several of the identified
chemicals that may affect the ozone layer are
refrigerants that contain Chlorine, Fluorine and Carbon
(CFCs) and those containing Hydrogen, Chlorine,
Fluorine and Carbon (HCFCs) Not all refrigerants
containing these compounds have the same potential
impact to the environment Trane advocates the
responsible handling of all refrigerants-including
industry replacements for CFCs and HCFCs such as
saturated or unsaturated HFCs and HCFCs
Important Responsible Refrigerant
Practices
Trane believes that responsible refrigerant practices
are important to the environment, our customers, and
the air conditioning industry All technicians who
handle refrigerants must be certified according to local
rules For the USA, the Federal Clean Air Act (Section
608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures In addition, some states or
municipalities may have additional requirements that
must also be adhered to for responsible management
of refrigerants Know the applicable laws and follow
them

Class I (high voltage) wiring between the heater and
unit is accomplished by the method of hard wiring
Class II wiring (low voltage) is accomplished by push-
on type wire connectors
Find the heater model number on the heater
nameplate Check Table 1, p 5 to ensure heater
selected is approved for use with the air handler in
which it is to be installed, and that the power supply is
compatible with this heater

NNoottee:: All phases of this installation must comply with
national, state, and local codes.
1 Remove duct flange from around air discharge on
top of the air handler Retain screws and flange for
(optional) installation on top of the heater See
Figure 1, p 6 and Figure 2, p 6
2 Remove the control wire knockout (Knockout #1)
from top of air handler and insert plastic bushing
supplied with heater This knockout will also be
used if single point power entry is utilized
IImmppoorrttaanntt:: For ventilation purposes, Heaters
L112A, L117A, L12 A, L129A, L 25A,
and L 5A require that an additional
knockout (knockout #2) be removed
(see Figure 1, p. 6). When using
BAYHTRL 25A with a TWE060* (5 ton)
air handler, the heater baffle must be
removed (see Figure , p. 7).
3 Remove air handler access panel and control box
cover
NNoottee:: Apply gasket to heater see heater gasket
installation sheet.
4 Place heater on air handler and secure in place with
the screws provided
Figure 1. Top of air handler single blower
Figure 2. Top of air handler dual blower
Low Voltage Wires (24 Volts)
1 For Heaters with single stage heat, there will be 1
brown wire and 1 black wire
2 For Heaters with two stage heat, there will be 1
brown wire, 1 black wire and 1 orange wire
3 Route the 2 or 3 low voltage wires down through
the plastic bushing in the knockout #1 to the low
voltage terminal block see Figure 4, p 8 and Figure
5, p 9 Wire according to heater wiring diagram
4 Wire ties and cable clamps supplied should be used

down through the plastic bushing in knockout #1
and into the air handler control box
2 For single phase there will be 2 red wires, and for 3
phase there will be 3 red wires
3 The 2 or 3 red wires should be hard wired to the
bottom contacts of the air handler contactor per the
wiring diagram for the standard air handlers For
the 2-speed VFD and SZVAV the wires connect to
the fuse block
IImmppoorrttaanntt:: When the dual point power entry option
is used, the high voltage wires, for
single point power entry, should remain
capped, coiled up and clamped inside
the heater control box.
4 When using dual point power entry, knockouts on
the control end of both the air handler and the
heater are to be used See Figure 4, p 8 &Figure 5,
p 9 for location of each
5 Replace air handler control box cover
6 Replace air handler access panel
7 Replace control box panel on accessory heater
8 Check blower rotation If incorrect, change
positions of any two power leads at fan contactor
(F) or fuse block After electrical hookup has been
completed, duct work can be assembled The duct
flanges removed from the air handler, can be
secured in place on top of the heater and the duct
work can be attached or the flange can be discarded
and the duct can be fashioned to fit up to the heater
