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.

• This system, including this controller, should be installed by personnel certied by Johnson Controls-Hitachi Air Conditioning.

Personnel must be qualied according to local, state, and national building and safety codes and regulations. Incorrect

installation could cause leaks, electric shock, re, or an explosion. In areas where Seismic Performance requirements are

specied, the appropriate measures should be taken during 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.

• Use only Johnson Controls-Hitachi Air Conditioning recommended, provided as standardized, or replacement parts.

• Johnson Controls-Hitachi Air Conditioning will not assume any liability for injuries or damage caused by not following steps

outlined or described in this manual. Unauthorized modications to Johnson Controls-Hitachi Air Conditioning products are

1. Safety Summary

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 unit to malfunction. The operation of the unit may also adversely aect

these same devices. Install the unit at least 10 . (approximately 3m) away from such devices.

• Locate the controller at a distance of at least 3 . (approximately 1m) from the electric lighting. Otherwise, the receiver part of

the controller may have diiculty receiving operation commands.

• 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.

• If there is a source of electrical interference near the power source, install noise suppression equipment (lter).

• 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 in the manual. If

there is no specied temperature, use the unit within 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.

• The Eco compact wired remote controller has near eld communication (NFC), which can improve service 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.

1. Safety Summary

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.

• Use specied cables between units and the controller.

• 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 is applied, proper bonding and

termination of the cable shield is required as per Johnson Controls-Hitachi 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 stopped.

Further, be sure to wait at least ve minutes before turning o the main power switch to the indoor 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 so forth) with the

specied capacity. Ensure that the wiring terminals are tightened securely to recommended torque specications.
