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.
WARNING
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.
WARNING
Personal Protective Equipment (PPE) Required!
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, tech
nicians 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, A
LWAYS re
fer to the appropriate SDS
and OSHA/GHS (Global Harmonized System of Classification and Labeling 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.
