Warnings, Cautions and Notices
Warnings, Cautions and Notices. Note that warnings, cautions and notices appear at
appropriate intervals throughout this manual. Warnings are provided to alert installing contractors
to potential hazards that could result in personal injury or death. Cautions are designed to alert
personnel to hazardous situations that could result in personal injury, while notices indicate a
situation that could result in equipment or property-damage-only accidents.\
Your personal safety and the proper operation of this machine depend upon the strict observance
of these precautions.
ATTENTION: Warnings, Cautions and Notices appear at appropriate sections throughout
this literature. Read these carefully.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
CAUTION: 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.
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 such as HCFCs and HFCs.
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. 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
Personal Protective Equipment (PPE) Required!
Installing/servicing this unit could result in exposure to electrical, mechanical and chemical
hazards.
• Before installing/servicing this unit, technicians MUST put on all Personal Protective
Equipment (PPE) recommended for the work being undertaken. ALWAYS refer to appropriate
MSDS sheets and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the appropriate MSDS
sheets and OSHA guidelines for information on allowable personal exposure levels, proper
respiratory protection and handling recommendations.
• If there is a risk of arc or flash, technicians MUST put on all necessary Personal Protective
Equipment (PPE) in accordance with NFPA70E for arc/flash protection PRIOR to servicing the
unit.
Failure to follow recommendations could result in death or serious injury.
