Installation, Operation, Maintenance

1 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 Commercial to 50 Ton 60 to Ton 50 HzCV or VAV Rooftop Air Conditionerswith ReliaTel Controls, R-410A RefrigerantNovember 2010RT-SVX34C-ENInstallation, Operation, MaintenanceModel Numbers B and later design sequenceTC*, TE*, YC*330B, 360B, 420B, 480B, 600B (60 Hz/3 phase)TC*, TE*, YC*275B, 305B, 350B, 400B, 500B (50 Hz/3 phase) 2010 Trane All rights reserved RT-SVX34C-ENWarnings, Cautions and NoticesWarnings, Cautions and Notices.

2 Note that warnings, cautions and notices appear at appropriate intervals throughout this manual. Warnings are provided to alert installing contractors 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 personal safety and the proper operation of this machine depend upon the strict observance of these 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.

3 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 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.

4 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.

It could also be used to alert against unsafe : Indicates a situation that could result in equipment or property-damage-only , Cautions and NoticesOverview of ManualOne copy of the appropriate service literature ships inside the control panel of each unit. The procedures discussed in this manual should only be performed by qualified, experienced HVAC technicians.

6 Note:Do not release refrigerant to the atmosphere! If adding or removing refrigerant is required, the service technician must comply with all federal, state, and local laws. This booklet describes the proper installation, startup, operation, and Maintenance procedures for TC_, TE_, and to 50 Ton CV (Constant Volume) and VAV (Variable Air Volume) applications. Refer to the table of contents for a listing specific topics. Refer to the "System Troubleshooting" section at the end of this manual for troubleshooting carefully reviewing the information within this manual and following the instructions, the risk of improper operation and/or component damage will be is important that periodic Maintenance be performed to help assure trouble free operation.

7 A Maintenance schedule is provided at the end of this manual. Should equipment failure occur, contact a qualified service organization with qualified, experienced HVAC technicians to properly diagnose and repair this equipment. 60 Hz units with standard options are certified by Underwriters Laboratory. 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.

8 ALWAYS refer to appropriate MSDS sheets and OSHA guidelines for proper PPE. When working with or around hazardous chemicals, ALWAYS refer to the appropriate MSDS 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 to follow recommendations could result in death or serious injury. WARNINGP roper Field Wiring and Grounding Required!

9 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 codes could result in death or serious injury. 4 RT-SVX34C-ENTable of ContentsLiterature Change History .. 2 Overview of Manual .. 360 Hz Description .. 8 Model Number Descriptions .. 850 Hz Description .. 10 General Information .. 11 Commonly Used Acronyms/Abbreviations .. 11 About the Unit.
