SAFETY WARNING
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.

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.
Personal Protective Equipment 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 SDS sheets and OSHA
guidelines for proper PPE. When working with or around hazardous chemicals,
ALWAYS refer to the appropriate SDS 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.
Heavy Object!
Failure to follow these instructions could result in death, serious injury,
and property damage.
Make certain that the lifting methods used to lift the duct furnace are
capable of supporting the weight of the heater during installation.
Ensure that all hardware used in the suspension of each duct furnace
is more than adequate for the job. Make certain that the structure to
which the duct furnace is to be mounted is capable of safely supporting
its weight. Under no circumstances must the gas lines, venting system,
or the electrical conduit be used to support the duct furnace. Do not
allow objects (i.e. ladder) or people to lean against the gas lines,
venting system, or electrical conduit for support.

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.
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. 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.
