1 TECHNICAL SUPPORT MANUAL Split System Air Conditioner N2A0, 3-Phase DANGER, WARNING, CAUTION, and NOTE The signal words DANGER, WARNING, CAU TION, and NOTE are used to identify levels of hazard seriousness. The signal word DANGER is only used on product labels to signify an immediate hazard. The signal words WARNING, CAUTION, and NOTE will be used on product labels and throughout this manual and other manuals that may apply to the product. DANGER - Immediate hazards which will result in severe personal injury or death. WARNING - Hazards or unsafe practices which could result in severe personal injury or death. CAUTION - Hazards or unsafe practices which may result in minor personal injury or product or property damage. NOTE - Used to highlight suggestions which will result in enhanced installation, reliability, or operation. Safety Labeling and Signal Words Signal Words in Manuals The signal word WARNING is used throughout this manual in the following manner: WARNING!

TABLE OF CONTENTS Wiring Diagrams Charging Chart Tech Labels Multipying Factors Exploded Drawings Parts List Number Identification ! WARNING DEATH, PERSONAL INJURY, AND/OR PROPERTY DAMAGE HAZARD Failure to carefully read and follow this warning could result in equipment malfunction, property damage, personal injury and/or death. Installation or repairs made by unqualified persons could result in equipment malfunction, property damage, personal injury and/or death. The information contained in this manual is intended for use by a qualified service technician familiar with safety procedures and equipped with the proper tools and test instruments. Installation must conform with local building codes and with the National Electrical Code NFPA70 current edition or Canadian Electrical Code Part 1 CSA C July 2007

2 Sizes: 36, 42, 48, Symbols are electrical representation only. 2. Compressor and fan motor furnished with inherent thermal protection. 3. To be wired in accordance with National Electric N.E.C. and local codes. 4. N.E.C. class 2, 24 V circuit, min. 40 VA required, 60 VA on units installed with LLS. 5. Use copper conductors only. Use conductors suitable for at least 75 C (167 F). 6. Connection for typical cooling only thermostat. For other arrangements see installation instructions. 7. If indoor section has a transformer with a grounded secondary, connect the grounded side to the BRN/YEL lead. 8. When start capacitor and relay are installed, start thermistor (PTC) is not used. 9. CH not used on all units. 10. If any of the original wire, as supplied, must be replaced, use the same or equivalent wire. 11. Check all electrical connections inside control box for tightness. 12. Do not attempt to operate unit until service valves have been opened. 13. Do not rapid cycle compressor. Compressor must be off 3 minutes to allow pressures to equalize between high and low side before starting. 14. Wire not present if HPS, LPS or CTD are used.
