SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation,
starting up, and servicing of heating, ventilating, and air-conditioning equipment can
be hazardous and requires specific knowledge and training. Improperly installed,
adjusted or altered equipment by an unqualified person could result in death or
serious injury. When working on the equipment, observe all precautions in the
literature and on the tags, stickers, and labels that are attached to the equipment.

Warnings, Cautions, and Notices
Read this manual thoroughly before operating or servicing this unit. 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:
WARNING Indicates a potentially hazardous situation which,
if not avoided, could result in death or serious
injury.
CAUTION 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
NOTICE 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 such
as HCFCs and HFCs.
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.
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring
MUST be performed by qualified personnel. Improperly installed and grounded
field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards,
you MUST follow requirements for field wiring installation and grounding as
described in NEC and your local/state electrical codes.
WARNING
Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or
serious injury. Technicians, in order to protect themselves from potential
electrical, mechanical, and chemical hazards, MUST follow precautions in this
manual and on the tags, stickers, and labels, as well as the instructions below:
• Before installing/servicing this unit, technicians MUST put on all PPE
required for the work being undertaken (Examples; cut resistant
gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing). ALWAYS refer to
appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the
appropriate SDS and OSHA/GHS (Global Harmonized System of
Classification and Labeling of Chemicals) guidelines for information on
allowable personal exposure levels, proper respiratory protection and
handling instructions.
If there is a risk of energized electrical contact, arc, or flash, technicians MUST
put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific
requirements for arc flash protection, PRIOR to servicing the unit. NEVER
PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING
WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE
ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR
INTENDED VOLTAGE.
WARNING
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.
• All Trane personnel must follow the company’s Environmental, Health and
Safety (EHS) policies when performing work such as hot work, electrical, fall
protection, lockout/tagout, refrigerant handling, etc. Where local
regulations are more stringent than these policies, those regulations
supersede these policies.
• Non-Trane personnel should always follow local regulations.

WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors before servicing could
result in death or serious injury.
Disconnect all electric power, including remote disconnects and discharge all
motor start/run capacitors before servicing. Follow proper lockout/ tagout
procedures to ensure the power cannot be inadvertently energized. Verify with
a CAT III or IV voltmeter rated per NFPA 70E that all capacitors have discharged.
2. Remove unit end panel, retain the screws for later use.

Factory Installed Damper (Field Set-Up)
Downflow Configuration
To position damper for downflow operation, complete the following steps:
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could result in death or serious
injury.
Disconnect all electric power, including remote disconnects before servicing.
Follow proper lockout/tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is present with a voltmeter.
1. Remove filter access panel.
2. Remove the lower screws in the end panel. See Figure 6. Lay block off
angle aside for later installation.

Remove screws and lay blockoff
angle aside.

3. Do not remove the screws in the upper row of the end panel.
4. Grasp the bottom of the end panel and pull the economizer assembly
outward into the operating position. See Figure 6.
5. Remove approximately 3-inches of gasket material from the bottom of
each corner post to expose the holes used to attach the economizer
assembly to the unit. See Figure 7.
6. With the screws provided, secure each side of the economizer assembly
by inserting a screw through the clearance hole in the bottom of the
corner post and into the engagement hole in the economizer assembly.
Refer to Figure 7.
Figure 7. Remove gasket material
7. Install the blockoff angle underneath the economizer. The blockoff angle
is designed to close the opening created, between the economizer and
the base, when the economizer assembly is in its operating position.
a. Holding the blockoff angle with the holes at the bottom and the
bottom angle outward, tilt the top forward and insert it into the
opening between the economizer and the unit base.
b. Press the bottom of the blockoff angle against the unit and line up
the holes. Using the provided screws, secure it into place.
Figure 8. Blockoff installation
8. Proceed to “Minimum Position Setting”.
Minimum Position Setting
WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when exposed to live electrical
components could result in death or serious injury.
When it is necessary to work with live electrical components, have a qualified
licensed electrician or other individual who has been properly trained in
handling live electrical components perform these tasks.
To adjust the minimum position setting and check out the damper, the
power must be connected.
1. Close the unit disconnect and place the zone sensor fan selector in the
fan “ON” position and the heat/cool selector in the “OFF” position. This
will place the damper in the minimum ventilation position.
2. To adjust the minimum position setting for the required ventilation air,
turn the potentiometer (on the damper motor) clockwise to “open” (to
increase the amount of ventilation) or counterclockwise to “close” (to
decrease the amount of ventilation). The damper will open to this setting
each time the blower circuit is energized.
3. When adjusting minimum position, the damper may move to the new
setting in several small steps. Once the damper has remained in position
for 10 - 15 seconds without movement, it can be assumed it is at the new
position.
4. Replace the filter access panel. The damper will close when the blower
circuit is de-energized.
Wiring Connections
Locate unit wiring harness plug PPM2A. The plug is located in the upper left
section of the return air section. Remove the cap covering the plug, and
connect to the economizer wiring harness.
