• All power wiring and communication cable installation must be performed by authorized service providers working in accordance with local,

state, and National Electrical Code regulations related to electrical equipment and wiring, and following the instructions in this manual. Failure

to do so may lead to electric shock and bodily injury or death.

• Verify 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 may lead to electric shock and bodily injury or death.

• Familiarize yourself with the location of the circuit breaker. Be sure that a 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 may cause bodily injury or death.

•

Never touch any power lines or live cables before all power is cutoff to the system. To do so may cause bodily injury or death.

• Undersized wiring may lead to unacceptable voltage at the unit and may cause a fire, which may cause bodily injury or death.

• Properly ground the Single Zone outdoor and indoor units. Ground wiring is required to prevent accidental electrical shock during current

leakage.

• Ground wiring must always be installed by a qualified technician.

• 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

may 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 National Electrical Code-approved earth ground can result in electric shock, physical injury or death.

• Consider ambient conditions (temperature, direct sunlight, inclement weather, etc.) when selecting, installing, and connecting the power

wiring.

• Properly ground the Single Zone outdoor and indoor unit. Improperly connected ground wire can cause communication problems from elec-

trical noise and motor current leakage. Ground wiring must always be installed by a qualified technician.

• If there is a possibility of electric surge, make sure the outdoor unit is properly grounded. Improperly ground wire can cause communication

problems.

• 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

may 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 National Electrical Code-approved earth ground can result in property damage and equipment malfunc-

tion.
