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.

WARNING

CAUTION

NOTICE

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. Failure to follow code could result in death or serious injury.
