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, Precautions, Notices
Safety advisories appear throughout this manual are 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:
Important
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 CFCs 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 Indicates a potentially hazardous situation which, if not avoided, could
result in death or serious injury.
PRECAUTIONsIndicates 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, Precautions, Notices
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/national electrical
codes.
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, technicians MUST put on all PPE required for the work
being undertaken (example: cut-resistant gloves/sleeves, butyl gloves, safety glasses, hard
hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to
appropriate Material Safety Data Sheets (MSDS)/Safety Data Sheets (SDS) and OSHA
guidelines for proper PPE.
• When working with or around hazardous chemicals, ALWAYS refer to the appropriate MSDS/
SDS and OSHA/GHS (Global Harmonized System of Classification and Labelling 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.

General Information
General
These instructions are offered as guidelines for the proper installation, start-up and operation for
universal coupling systems 2MX/2MW. However, these do not contain all fully required procedures
for a continued operation free of obstacles. Therefore, it is important to contract a professional
service agency for such matters. Read these instructions carefully before installing the equipment.
Warranty
Warranty is based upon general terms and conditions of the manufacturer. Warranty may be
nullified if the equipment were to be modified or repaired without the express approval of the
manufacturer, or if operation limitations were to be exceeded, or if electrical wiring of the system
were to be altered. Any damage to the equipment as a result of bad use of same, or lack of
maintenance, or non-compliance with instructions offered by the manufacturer, will not be covered
by the warranty. Warranty will be automatically cancelled if the user does not adhere to the rules
described in this manual.
Reception
Upon arrival, inspect the unit before signing approval of delivery. Specify any damages observed
at the time of delivery and report same in writing to the transportation company, within 72 hours
of delivery. At the same time, notify your local sales representative of these damages. Inspect the
unit within the first 7 days of delivery. If any concealed damage is detected, advise of same in
writing to the transportation company within 7 days of delivery, as well as to your local sales
representative.
About the Unit
Before shipping, the unit covered in this manual are assembled, dehydrated, charged and leak
tested. This document contains information related to the units of Universal Coupling.
Refrigerant
Refrigerant provided by the manufacturer complies with all Trane unit requirements. When using
recycled or reprocessed refrigerant, it is recommended to ensure that the quality is equivalent to
new refrigerant. To do this, it will be necessary to order an analysis of said refrigerant by a
specialized laboratory. Any action contrary to this measure, will compel the manufacturer to anull
the warranty.
IMPORTANT:
The unit must be installed in accordance with national regulations for electrical installations.
These instructions do not cover all variations in the system, nor do they foresee all possible
contingency. If further information were to be required or if problems should arise which are not
covered sufficiently in this manual, the matter should be turned over to the local Trane Sales Office.

Security Recommendations
Security Recommendations
The following recommendations will help to obtain the best performance of your air-conditioning
unit:
• Do not leave doors and windows open for a long period of time while the unit is in operation
as it will reduce the unit’s air-conditioning capacity.
•Do not place heat sources near the air conditioner as it will reduce the unit’s air-conditioning capacity.
• When the unit is not used for an extended period of time, disconnect incoming power to the
unit.
• If some smell of burning or smoke is detected, immediately disconnect all power supply to the
unit and alert your authorized service agency of the situation. If this condition persists, it could
be due to damages found in the unit which could possibly lead to electric shock or fire.
• Make sure the unit is not close to any type of fuel sprays (at least 1 meter in distance) in order
to avoid fire or explosion hazards.
• Never try to repair the air conditioning unit by yourselves. An erroneous repair could lead to
electrocution or fire. Always call your service agency for all repairs.
• Never splice or join electrical wiring, and never use an extension cord. This practice could lead
to super-heating or fire.
• Electrical power supply should be of appropriate rated amperage and conform to all local
codes.
• In order to prevent electric shock or fire, do not cut or damage power or control cords. If any
of these cords are found to be damaged, request their replacement only to qualified personnel.
• Do not operate the unit without air filters installed. Otherwise, the penetration of debris or dirt
could damage the unit. Filters must be removed and cleaned periodically to ensure their
maximum efficiency.
NOTICE:
Air Flow Restriction
Ascertain that system incoming air flow and outgoing air flow is free of all obstructions.
Otherwise, it could prevent the unit’s good performance and could provoke damages to the
equipment.
