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.

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:
WARNING Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTIONsIndicates 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 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.
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,
ALWAYSrefer tothe appropriateSDSandOSHA/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.

General Information
Jobsite Inspection
Each unit has been inspected, tested and operated at the
factory by production and quality associates prior to being
crated for safe transit. However, rough handling or
accidents can occur resulting in damaged equipment
being delivered. Always perform the following checks
before accepting a unit:
• Do not sign the bill of lading accepting the unit(s) until
inspection has been completed. Check for damage
promptly after the unit(s) are unloaded. Once the bill of
lading is signed at the jobsite, the unit(s) are now the
property of the SOLD TO party and future freight claims
MAY NOT be accepted by the freight company.
• Check the unit model numbers on the bill of lading
against those ordered and received to assure
equipment is AS ORDERED.
• Check that the refrigerant charge has been retained
during shipment by use of gauges. Schrader taps are
located and labeled internal to the cabinet.
Figure 1. Schrader location
Important: Verify the charge has been retained. Then,
re-install schrader caps to ensure that
refrigerant leakage does not occur.
Re-install the unit panel using all factory
provided screws.
Jobsite Storage
NOTICE:
Microbial Growth!
Wet interior unit insulation can become an
amplification site for microbial growth (mold), which
could result in odors and damage to the equipment and
building materials. If there is evidence of microbial
growth on the interior insulation, it should be removed
and replaced prior to operating the system.
NOTICE:
Microbial Growth!
Failure to follow instructions below could result in
odors and damage to the equipment and building
materials.The floor or foundation must be level and the
condensate drain at the proper height for proper coil
drainage and condensate flow. Standing water and wet
surfaces inside the equipment can become an
amplification site for microbial growth (mold).
This unit is intended for indoor use only. To protect the unit
from damage due to the elements, and to prevent possible
IAQ contaminant sources from growing, the unit should be
stored indoors. If indoor storage is not possible, the
following provisions for outdoor storage must be met.
• Place the unit(s) on a dry surface or raise above the
ground to assure adequate air circulation beneath the
unit. This is to assure that no portion of the unit
contacts standing water at any time.
• Cover the unit(s) with a water proof tarp to protect
them from the elements.
•Make provisions for continuous venting of the covered
units to prevent moisture from standing on the unit(s)
surfaces. Wet interior unit insulation can become an
amplification site for microbial growth which has been
determined to be a cause of odors and serious health
related indoor air quality problems.
• Store units in the normal UP orientation. Storing units
in this manner maintains oil in the compressor.
• Units may be stacked two high.
Important: Equipment is shipped FOB (Free on Board)
at the manufacturer. Therefore, freight
claims for damages against the carrier must
be initiated by the receiver.

Unit Dimensions
Service Clearances
Access to the unit for servicing purposes should be
provided at installation. All configurations require
clearance from other mechanical and electrical equipment
on three service sides (shown below). This enables panel
removal from the unit for service/maintenance ability.
