Introduction
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as 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:
WARNING Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAUTIONsIndicates 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 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, technicians 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, ALWAYS refer 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.
WARNING
Follow EHS Policies!
Failure to follow instructions below could result in death or serious injury.
• All Trane personnel must follow the company’s Environmental, Health and Safety (EHS)
policies when performing work such as hot work, electrical, fall protection, lockout/tagout,
refrigerant handling, etc. Where local regulations are more stringent than these policies,
those regulations supersede these policies.
• Non-Trane personnel should always follow local regulations.

Pre-Installation
Pre-Installation
This section provides the following pre-installation information:
• Location considerations
• Height requirements
• Mounting surfaces
Location Considerations
Placement of the sensor is critical to proper operation. When selecting a location, avoid the
following:
• Areas of direct sunlight
• Areas in the direct airstream of air diffusers
• Exterior walls and other walls that have a temperature differential between the two sides
• Areas that are close to heat sources such as sunlight, appliances, concealed pipes, chimneys,
or other heat-generating equipment
• Drafty areas
• Dead spots behind doors, projection screens, or corners
• Walls that are subject to high vibration
• Areas with high humidity
• High traffic areas (to reduce accidental damage or tampering)
Height Requirements
The recommended maximum mounting height is 54 inches from the bottom of the back plate to
the floor. If a parallel approach by a person in a wheelchair is required, reduce the maximum height
to 48 inches.
Note: Consult section 4.27.3 of the 2002 ADA (Americans with Disability Act) guideline, and local
building codes, for further details regarding wheelchair requirements.
Mounting Surfaces
Using the hardware provided, mount the back plate to a flat surface such as sheetrock or plaster,
or an electrical junction box. The sensor must be mounted plumb for accurate temperature control
and to ensure proper air movement through the sensor.
• If mounting onto sheetrock or plaster, use the plastic threaded anchors (pre-drilling holes is not
usually necessary) and the two M3.5 x 20 mm mounting screws.
• For mounting onto an electrical junction box, use the two 6-32 x 3/4 in. screws.
