SAFETY CONSIDERATIONSInstalling, starting up, and servicing air--conditioning equipmentcan be hazardous due to system pressures, electrical components,and equipment location (roofs, elevated structures, etc.).Only trained, qualified installers and service mechanics shouldinstall, start--up, and service this equipment.Untrained personnel can perform basic maintenance functions suchas cleaning coils. All other operations should be performed bytrained service personnel.When working on the equipment, observe precautions in theliterature and on tags, stickers, and labels attached to theequipment.Follow all safety codes. Wear safety glasses and work gloves. Keepquenching cloth and fire extinguisher nearby when brazing. Usecare in handling, rigging, and setting bulky equipment.Read these instructions thoroughly and follow all warnings orcautions included in literature and attached to the unit. Consultlocal building codes and National Electrical Code (NEC) forspecial requirements. Recognize safety information. This is the

safety--alert symbol !! . When you see this symbol on the unit andin instructions or manuals, be alert to the potential for personalinjury.Understand these signal words: DANGER, WARNING, andCAUTION. These words are used with the safety--alert symbol.DANGER identifies the most serious hazards which will result insevere personal injury or death. WARNING signifies hazardswhich could result in personal injury or death. CAUTION is usedto identify unsafe practices which may result in minor personalinjury or product and property damage. NOTE is used to highlightsuggestions which will result in enhanced installation, reliability, oroperation.

! WARNINGELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personalinjury or death.

Before installing, modifying, or servicing system, mainelectrical disconnect switch must be in the OFFposition. There may be more than 1 disconnect switch.Lock out and tag switch with a suitable warning label.

EXPLOSION HAZARD

Failure to follow this warning couldresult in death, serious personal injury,and/or property damage.

Never use air or gases containingoxygen for leak testing or operatingrefrigerant compressors. Pressurizedmixtures of air or gases containingoxygen can lead to an explosion.

! WARNING

CAUTION!

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipmentdamage or improper operation.

Do not bury more than 36 in. (914 mm) of refrigerant pipein the ground. If any section of pipe is buried, there must bea 6 in. (152 mm) vertical rise to the valve connections onthe outdoor units. If more than the recommended length isburied, refrigerant may migrate to the cooler buried sectionduring extended periods of system shutdown. This causesrefrigerant slugging and could possibly damage thecompressor at start--up.

SYSTEM REQUIREMENTSAllow sufficient space for airflow and servicing unit.Recommended Connection Method for Power and Communi-cation Wiring (To minimize communication wiring interfer-ence)Power Wiring:The main power is supplied to the outdoor unit. The field suppliedconnecting cable from the outdoor unit to indoor unit consists ofthree (3) wires and provides the power for the indoor unit. Twowires are high voltage AC power and one is a ground wire.Consult your local building codes and the NEC (NationalElectrical Code) or CEC (Canadian Electrical Code) for specialrequirements.All wires must be sized per NEC or CEC and local codes. UseElectrical Data table MCA (minimum circuit amps) and MOCP(maximum over current protection) to correctly size the wires andthe disconnect fuse or breakers respectively.Per caution note, only copper conductors with a minimum 300 voltrating and 2/64--inch thick insulation must be used.Communication Wiring:A separate shielded copper conductor only, with a minimum 300volt rating and 2/64--inch thick insulation, must be used as thecommunication wire from the outdoor unit to the indoor unit.To minimize voltage drop, the factory recommended wire size is 14/3 stranded with a ground. In special cases where there is high electrical interference, please use a separate shielded 16GA stranded control wire.

CAUTION!

EQUIPMENT DAMAGE HAZARD

Failure to follow this caution may result in equipmentdamage or improper operation.

S Wires should be sized based on NEC and local codes.

S Use copper conductors only with a minimum 300 voltrating and 2/64 inch thick insulation.
