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
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 practices.
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
refrigerantsincluding 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
statesor 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/national 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 countryspecific 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.

General
Read these instructions and become familiar with the four duct alignment
bracket assemblies before installation. There are two bracket assemblies for
the left side and two for the right side shown in Figure 1 and Figure 2.
The footprint of the unit is wider and longer than the roof curb. The duct
alignment brackets provide the required clearance (0.25 inches) to the roof
curb. The installation requires the brackets to be connected to the base, so
access to the base is required. It is recommended to do the installation with
the unit supported on blocks at corners at least 6 inches high from the
ground.

Installation
-
Remove the fork bracket, front base plate, base board and the base shipping bracket as shown in Figure 3. These parts can be discarded.
Figure 3. Remove parts
-
Install the four duct alignment brackets as illustrated on Figure 4 (details A and
B). Align the label located on the brackets with the slots on the base rail, as illustrated in Figure 4, detail C. The brackets on the right side use three screws and the ones on the left side use four screws.

-
Follow the instructions in the IOM for unit rigging. Use the installed brackets for alignment when installing the unit on the curb. The unit tends to tilt on the compressor end (refer to IOM for center of gravity information). Use that end to align the curb alignment brackets with the curb.
-
Figure 5 and Figure 6 show different views of the unit installed on the roof curb. Figure 7 shows the cross section of the duct alignment bracket and the roof curb.
