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

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.
