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. |\n\nDecember 2022 PKGP-SVX010A-EN  \nIntroduction  \nRead this manual thoroughly before operating or servicing this unit.  \nWarnings, Cautions, and Notices  \nSafety 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.  \nThe three types of advisories are defined as follows:  \nIndicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.  \nIndicates 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.  \nIndicates a situation that could result in equipment or property-damage only accidents.  \nImportant Environmental Concerns  \nScientific 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 refrigerantsincluding industry replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.  \nImportant Responsible Refrigerant Practices  \nTrane 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.  \n\n|  WARNING |\n| --- |\n| Proper Field Wiring and Grounding Required!\u003Cbr>Failure to follow code could result in death or serious injury.\u003Cbr>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. |\n\n\n|  WARNING |\n| --- |\n| Personal Protective Equipment (PPE) Required!\u003Cbr>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:\u003Cbr>• 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) .
