Trane Performance Climate Changer Installation and operating instructions

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.

Warnings, Cautions and Notices
Warnings, Cautions and Notices. Note that warnings, cautions and notices appear at
appropriateintervalsthroughoutthismanual.Warningsareprovidedtoalertinstallingcontractors
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.
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
identifiedchemicalsthatmay affecttheozonelayer are refrigerantsthatcontain Chlorine, Fluorine
andCarbon(CFCs)andthosecontainingHydrogen,Chlorine,FluorineandCarbon(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,recoveringandrecyclingofcertainrefrigerantsandtheequipmentthatisusedinthese
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.
Ultraviolet (UV) Germicidal Irradiation Lights!
The United States Environmental Protection Agency (EPA) believes that molds and bacteria inside
buildings have the potential to cause health problems in sensitive individuals. If specified, Trane
providesultravioletlights(UV-C) asafactory-engineeredandinstalledoptionin selectcommercial
air handling products for the purpose of reducing microbiological growth (mold and bacteria)
within the equipment. When factory provided, polymer materials that are susceptible to
deterioration by the UV-C light will be substituted or shielded from direct exposure to the light. In
addition, UV-C radiation can damage human tissue, namely eyes and skin. To reduce the potential
for inadvertent exposure to the lights by operating and maintenance personnel, electrical
interlocks that automatically disconnect power to the lights are provided atall unit entry points to
equipment where lights are located.
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.

Warnings, Cautions and Notices
WARNING
Contains Refrigerant!
System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure
before opening the system. See unit nameplate for refrigerant type. Do not use non-approved
refrigerants, refrigerant substitutes, or refrigerant additives.
Failure to follow proper procedures or the use of non-approved refrigerants, refrigerant
substitutes, or refrigerant additives could result in death or serious injury or equipment damage.
WARNING
Hazard of Explosion!
Use only dry nitrogen with a pressure regulator for pressurizing unit. Do not use acetylene,
oxygen or compressed air or mixtures containing them for pressure testing. Do not use mixtures
of a hydrogen containing refrigerant and air above atmospheric pressure for pressure testing as
they may become flammable and could result in an explosion. Refrigerant, when used as a trace
gas should only be mixed with dry nitrogen for pressurizing units. Failure to follow these
recommendations could result in death or serious injury or equipment or property-only damage.
WARNING
Equipment Damage From Ultraviolet (UV) Lights!
Trane does not recommend field installation of ultraviolet lights in its air handling equipment for
the intended purpose of improving indoor air quality. High intensity C-band ultraviolet light is
known to severely damage polymer (plastic) materials and poses a personal safety risk to
anyone exposed to the light without proper personal protective equipment (could cause
damage to eyes and skin). Polymer materials commonly found in HVAC equipment that may be
susceptible include insulation on electrical wiring, fan belts, thermal insulation, various
fasteners and bushings. Degradation of these materials can result in serious damage to the
equipment.
Trane accepts no responsibility for the performance or operation of our air handling equipment
in which ultraviolet devices were installed outside of the Trane factory.
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 and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to appropriate MSDS and
OSHA guidelines for information on allowable personal exposure levels, proper respiratory
protection and handling recommendations.
• Ifthereisariskofarcorflash,techniciansMUSTputonallPersonalProtectiveEquipment(PPE)
in accordance with NFPA70E or other country-specific requirements for arc/flash protection
PRIOR to servicing the unit.
Failure to follow recommendations could result in death or serious injury.
