injury.
Indicates a hazardous situation that, if not avoided, could result in minor or moderate
injury.
Indicates information considered important, but not hazard-related (for example,
messages relating to property damage).
For the operation of the product, please read and follow this safety summary strictly. Otherwise, improper
operation may cause injury or death.
General Precautions
To reduce the risk of serious injury or death, read these instructions thoroughly
and follow all warnings or cautions included in all manuals that accompanied the
product and are attached to the unit. Refer back to these safety instructions as
needed.

installation to guard against possible damage or injury that might occur in an earthquake. If the unit is not
installed appropriately correctly, injuries may occur because of a falling unit.
• Use appropriate Personal Protective Equipment (PPE), such as gloves, protective goggles, and electrical
protection equipment and tools suited for electrical operation purposes.
• When transporting, be careful when picking up, moving and mounting these units. Although the controller
may be packed using plastic straps, do not use them for transporting from one location to another.
Do not stand on or put any material on the controller.
• When installing the controller cabling to the units, do not touch or adjust any safety devices inside the indoor
or outdoor units. All safety features, disengagement, and interlocks must be in place and functioning correctly
before the equipment is put into operation. If these devices are improperly adjusted or tampered with in any
way, a serious accident can occur. Never bypass, wire around, or jump-out any safety device or switch.

1. Safety Summary
2A11766820A
Take the following precautions to reduce the risk of property damage.
• Do not touch the main circuit board or electronic components in the controller or remote devices.
Make sure that dust and/or steam does not accumulate on the circuit board.
• When installing the unit in a hospital or other facility where electromagnetic waves are generated from nearby
medical and/or electronic devices, be prepared for noise and Electromagnetic Interference (EMI). Do not
install where the waves can directly radiate into the electrical box, controller cable, or controller. Inverters,
appliances, high-frequency medical equipment, and radio communications equipment. EMI may cause the
•
• If the wired controller is installed in a location where electromagnetic energy is generated, make sure that the
wired controller is shielded and cables are sleeved inside conduit tubing.
•
• During the test run, check the unit’s operation temperature. If the unit is used in an environment where the
temperature exceeds the operation boundary, it may cause severe damage. Check the operation temperature
boundary of 32°F to 104°F (0°C to 40°C).
• Perform properly electrical wiring work. The details of the electrical wiring connection are described in the
"Electrical Wiring" of corresponding Installation and Maintenance Manual.
•
and installation. If the wired remote controller may be accessible to unauthorized third-party, please set the
NFC to "Disable" by referring to the installation manual.
Installation Precautions
Take the following precautions to reduce the risk of electric shock, fire, or
explosion resulting in serious injury or death:
• If the remote sensors are not used with this controller, then do not install this controller…
○In a room where there is no thermostat.
○Where the unit is exposed to direct sunshine or direct light.
○Where the unit is in close proximity to a heat source.
○
○In areas with poor air circulation and ventilation.
• Perform a test run using the controller to ensure normal operation. Safety guards, shields, barriers, covers, and
and clothing away from any moving parts.
After installation work for the system has been completed, explain the "Safety Precautions," use, and
maintenance of the unit to the customer according to the information in all manuals that accompanied the
system. All manuals and warranty information must be given to the user or left near the Indoor Unit.

Electrical Precautions
Take the following precautions to reduce the risk of electric shock, fire, or
explosion resulting in serious injury or death:
• Only use electrical protection equipment and tools suited for this installation.
• Insulate the wired controller against moisture and temperature extremes.
•
• Communication cabling must be a minimum of 18-Gauge, 2-Conductor, Stranded Copper.
Shielded cable must be considered for applications and routing in areas of high EMI and other sources of
potentially excessive electrical noise to reduce the potential for communication errors. When shielded cabling
Air Conditioning guidelines. Plenum and riser ratings for communication cables must be considered per
application and local code requirements.
• The polarity of the input terminals is important, so be sure to match the polarity when using contacts that
have polarity.
•
Highly dangerous electrical voltages may be used in this system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and inadequate grounding can cause serious injury or death.
• Before installing the controller or remote devices, ensure that the indoor and outdoor unit operation has been
or outdoor units. Otherwise, water leakage or electrical breakdown may result.
•
Do not open the service cover or access panel to the indoor or outdoor units without turning OFF the main
power supply. Before connecting or servicing the controller or cables to indoor or outdoor units, open and tag
all disconnect switches. Never assume electrical power is disconnected. Verify with a meter and equipment.
• Use an exclusive power supply at the controller’s rated voltage.
•
Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit breaker, and
•
In addition, run wires securely through the wiring access channel.
• When installing the power lines, do not apply tension to the cables. Secure the suspended cables at regular
intervals, but not too tightly.
• Make sure that the terminals do not come into contact with the surface of the electrical box.
If the terminals are too close to the surface, it may lead to failures at the terminal connection.
• Do not pour water on the controller as it could cause electric shock and/or damage the unit.
• Check that the ground wire is securely connected. Do not connect ground wiring to gas piping, water piping,
lighting conductor, or telephone ground wiring.
