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.

NOTICE

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 property­damage 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.

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.

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 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.
