WIRING
• All power wiring (line voltage) and communication cable installation must be performed by trained service providers working in accordance
with all local, state, and National Electrical Code (NEC) / UL / ETL federal regulations related to electrical equipment and wiring, and following
the manufacturer product diagrams, requirements, and instructions in this manual. Electric shock can cause physical injury or death.
• Be sure that main power to the unit is completely off before proceeding. Follow all safety and warning information outlined at the beginning of
this manual. Failure to do so will cause electric shock and bodily injury.
• Install a main shutoff switch or circuit breaker that interrupts all power sources simultaneously (circuit breaker must be resistant to electro-
magnetic currents). Be sure that the circuit breaker or some other emergency power cutoff device is in place before any power wiring is done
to the system. Failure to do so will cause bodily injury or death.
•
Never touch any power lines or live cables before all power is cutoff to the system. To do so will cause bodily injury or death.
• Power wiring and communication cable sizes must comply with all applicable federal, state, and local codes. Undersized wiring will lead to
unacceptable voltage at the unit and will cause a fire, which will cause bodily injury or death.
• Properly ground the outdoor unit, indoor units, and branch distribution units. Ground wiring must always be installed by a trained technician.
Ground wiring is required to prevent accidental electrical shock during current leakage, which will cause bodily injury or death.
• Verify that the circuit breaker is set to OFF before installing the wiring system. Electric shock can cause physical injury or death.
• Install appropriately sized breakers / fuses / overcurrent protection switches and wiring in accordance with local, state, and National Electrical
Code regulations related to electrical equipment and wiring, and following the instructions in this manual. Using an oversized breaker or fuse
will result in electric shock, physical injury or death.
•
Do not connect ground wire to refrigerant, gas, or water piping; to lightning rods; to telephone ground wiring; or to the building plumbing
system. Failure to properly provide a NEC-approved earth ground can result in electric shock, fire, physical injury or death.
• Consider ambient conditions (temperature, direct sunlight, inclement weather, etc.) when selecting, installing, and connecting the power wir-
ing.
• Properly ground the outdoor unit, indoor units, and branch distribution units. Ground wiring must always be installed by a trained technician.
Improperly grounded wire can cause communication problems from electrical noise, and motor current leakage.
• Install appropriately sized breakers / fuses / overcurrent protection switches and wiring in accordance with local, state, and NEC regulations
related to electrical equipment and wiring, and following the instructions in this manual. Generated overcurrent will include some amount of
direct current. Using an oversized breaker or fuse will result in equipment malfunction and property damage.
•
Do not connect ground wire to refrigerant, gas, or water piping; to lightning rods; to telephone ground wiring; or to the building plumbing
system. Failure to properly provide a NEC-approved earth ground can result in property damage and equipment malfunction.
•
Do not operate the air conditioning system until the refrigerant piping installation is complete. Operating the system before refrigerant
piping is finalized will damage the compressor.
