Introduction
Warnings, Cautions, and Notices
Important Environmental Concerns
Important Responsible Refrigerant Practices
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 property-damage
only accidents.
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.
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.
