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.
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. 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.
About the Manual
Note: This document is customer property and must be
retained by the unit owner for use by maintenance
personnel.
These units are equipped with electronic Unit Control Modules (UCM). Refer to the “Startup” and “Test Mode”
procedures within this Installation, Operation, and
The three types of advisories are defined as follows:
WARNINGIndicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTIONs
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.
NOTICEIndicates a situation that could result in
equipment or property-damage only
accidents.
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!
Installing/servicing this unit could result in exposure to
electrical, mechanical and chemical hazards.
 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 Material Safety Data Sheets (MSDS)/Safety Data Sheets (SDS) and OSHA
guidelines for proper PPE.
 When working with or around hazardous chemicals, ALWAYS refer to the appropriate MSDS/SDS andOSHA/GHS (Global Harmonized System of
Classification and Labelling 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.
Failure to follow instructions could result in death or
serious injury.

Unit Inspection
As soon as the unit arrives at the job site
[ ] Verify that the nameplate data matches the data on
the sales order and bill of lading (including electrical
data).
[ ] Verify that the power supply complies with the unit
nameplate specifications.
[ ] Verify that the power supply complies with the
electric heater specifications on the unit nameplate.
[ ] Visually inspect the exterior of the unit, including the
roof, for signs of shipping damage.
[ ] Check for material shortages. Refer to the
Component Layout and Ship with Location illustration.
Important: If the job site inspection of the unit reveals
damage or material shortages, file a claim
with the carrier immediately. Specify the
type and extent of the damage on the “bill of
lading” before signing.
[ ] Visually inspect the internal components for
shipping damage as soon as possible after delivery
and before it is stored. Do notwalk on the sheet metal
base pans.
[ ] If concealed damage is discovered, notify the
carriers terminal of damage immediately by phone
and by mail. Concealed damage must be reported
within 15 days.
Request an immediate joint inspection of the damage
by the carrier and the consignee. Do not remove
damaged material from the receiving location. Take
photos of the damage, if possible. The owner must
provide reasonable evidence that the damage did not
occur after delivery.
[ ] Remove the protective plastic coverings that
shipped over the compressors.
Storage
Take precautions to prevent condensate from forming inside the unit electrical compartments and motors if:
a. The unit is stored before it is installed; or,
b. The unit is set on the roof curb, and temporary heatis provided in the building. Isolate all side panel
service entrances and base pan openings (e.g.,
conduit holes, S/A and R/A openings, and flue openings) from the ambient air until the unit is
ready for startup.
Note: Do not use the unit heater for temporary heat
without first completing the startup procedure
detailed under “Unit Startup,” p. 98.
Trane will not assume any responsibility for equipment damage resulting from condensate accumulation on the
unit electrical and/or mechanical components.
Unit Clearances
Figure 10, p. 23 Table 4, p. 23 illustrates the minimum
operating and service clearances for either a single or
multiple unit installation. These clearances are the
minimum distances necessary for adequate service,
cataloged unit capacity, and peak operating efficiency.
Providing less than the recommended clearances may
result in condenser coil starvation, “short-circulating” of
exhaust and economizer airflows, or recirculation of hot
condenser air.
Unit Dimensions and Weight Information
WARNING
No Step Surface!
Do not walk on the sheet metal drain pan. Walking on
the drain pan could cause the supporting metal to
collapse, resulting in the operator/technician to fall.
Failure to follow this recommendation could result in
death or serious injury.

Unit Description
Each Trane commercial, single-zone rooftop air
conditioner ships fully assembled from the factory. An
optional roof curb, specifically designed for the S_HJ units
is available from Trane. The roof curb kit must be field
assembled and installed according to the latest edition of
the roof curb installation manual.
Trane Commercial Rooftop Units are controlled by a microelectronic control system that consists of a network
of modules and are referred to as Unit Control Modules
(UCM).The acronym UCM is used extensively throughout
this document when referring to the control system
network. These modules through Proportional/Integral
control algorithms perform specific unit functions which
provide the best possible comfort level for the customer.
They are mounted in the control panel and are factory wired to their respective internal components. They
receive and interpret information from other unit
