SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and airconditioning 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.

Introduction
Read this manual thoroughly before operating or servicing this unit.
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
CAUTIONs
NOTICE
Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
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.
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 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.
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.
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 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 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.
Failure to follow instructions could result in death or serious injury.

Password Protected Screens
Some of the operating displays on the Human Interface LCD screens and require a password to change.The following screens display the various programming sections that require a password in order to view or to modify the preset operating parameters.The password for each screen is a different series of + (Plus) or - (Minus) key strokes in a predefined sequence. Shown below are the password protected screens, and the passwords for accessing them.
The following screens display the various programming sections that require a specific password to be entered by a qualified operator in order to modify the operating parameters.The following screen will appear if the password is not entered within approximately 15 seconds.

Navigating the Human Interface Screens
In the following sections the user will be presented with a number of screens and submenus that follow the selection of a main menu key entry (Status, Setpoints, Diagnostics, Setup, Configuration, Service Mode and Custom).When a submenu is presented, it may be accessed by pressing the Enter key or, skipped entirely by pressing the Next key. Upon entering a menu, or submenu, the user will navigate through the desired selections by pressing the Next and Previous keys.The most probable keystroke would be to press Next to cycle forward through the screens as shown in these sections, but pressing the Previous key may be desirable to review previous screens or to quickly navigate to the end of a menu.
Once the user has navigated to a desired selection, the + (Plus) and - (Minus) keys will be pressed to cycle through the selection range of the menu item.The range of each item selected is dependent upon the item and is listed for each screen in the following sections. For instance, if the user has selected a Configuration item typical choices displayed with each + (Plus) or - (Minus) keystroke may be Installed or Not Installed. If a Setup menu were accessed a choice may be Enabled or Disabled.Temperature Setpoints will typically cycle through their range one degree at a time, and so on. Similar to pressing the Previous key above, pressing the - (Minus) key to decrement through the range may provide quick access to the desired value.
Once a change has been made to the desired menu item the user will press the Enter key to accept the change, or press the Cancel key to ignore the modification and return the displayed item to its original value.

STATUS Menu
The status menu is used to view various operating conditions such as temperatures, pressures and humidity levels. It is also used to view unit component status such as fan, compressor, heater, and economizer operation, as well as setpoint status.
The screens shown in this section are for example only. Pressing the + (Plus) key while viewing any of the status display screens will add that screen to the Custom menu. While viewing the Custom menu, a screen can be removed by pressing the – (Minus) key.
When a status screen is displayed for 30 minutes without a key being pressed, the LCD screen will revert to the general operating status display. If this happens, press the Status key again to return to the status menu.The following are examples of status screens that may be viewed by pressing the Status key.
Note:
1.Many of the screens displayed in this section are applicable only for the options that are installed in the unit and may not be visible on your unit.
2.The range for some selections depend upon a sensor connected to a control module. Normal ranges expected will be listed for each screen shown. If the sensor is operating outside its normal limits, or has failed, “+ERR” will appear if out of range high, and “-ERR” if it is out of range low.
Press the Status key to begin viewing the status screens.
