SAFETY MESSAGES

Indicates a hazardous situation that, if not avoided, could result in death or serious injury.

Indicates a hazardous situation that, if not avoided, could result in minor or moderate injury.

Indicates information considered important, but not hazard-related (e.g. messages relating to property damage).

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 this product and the indoor and outdoor units.       This system, including this controller, should be installed by personnel certified by Johnson Controls, Inc. Personnel must be qualified according to local, state and national building and safety codes and regulations. Incorrect installation could cause leaks, electric shock, fire or explosion.

Use appropriate personal protective equipment, such as gloves and protective goggles and electrical protection equipment and tools suited for electrical operation purposes.

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 or jump out any safety device.

Use only Johnson Controls recommended or provided as standardized or replacement parts.

Johnson Controls shall not assume any liability for injuries or damage caused by not following steps outlined or described in this manual.

Unauthorized modifications to Johnson Controls products are prohibited as they… may create hazards which could result in death, serious injury or equipment damage.

will void product warranties.

may invalidate product regulatory certifications.

may violate OSHA standards.

i

ii 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. Also, make sure that dust and/or steam does not accumulate on the circuit board.

Locate the wireless zone controller at a distance of at least 3 ft.

(approx. 1m) between the indoor unit and electric lighting. Otherwise, the receiver part of the unit may have difficulty receiving operation commands.

If the wired zone controller is installed in a location where electromagnetic radiation is generated, make sure that the wired zone 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 (filter).

During the run test, 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 operational temperature boundary in the manual. If there is no specified temperature, use the unit within the operational temperature boundary of 35°~104°F (0~40°C).

Read installation and appropriate user manuals for connection with PC or peripheral devices. If a warning window appears on PC, the product stops, does not work properly or works intermittently, immediately stop using the equipment.

INSTALLATION PRECAUTIONS

To reduce the risk of serious injury or death, the following installation precautions must be followed:   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.

where the unit will be in close proximity to a heat source.

where hot/cold air from the outdoors, or a draft from elsewhere (such as air vents, diffusers or grilles) can affect air circulation.

in areas with poor air circulation and ventilation.

Perform the run test using the controller to ensure normal operation.

Safety guards, shields, barriers, covers, and protective devices must be in place while the compressor/unit is operating. During the run test, keep fingers 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 zone controller against moisture and temperature extremes.

Use specified cables between units and controller.

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 five minutes before turning off 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 controller or cables to indoor or outdoor units, open and tag all disconnect switches. Never assume electrical power is disconnected. Check with 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 specified capacity. Ensure that the wiring terminals are tightened securely to recommended torque specifications.

This equipment can be installed with a Ground Fault Circuit Breaker (GFCI), which is a recognized measure for added protection to a properly grounded unit. Install appropriate sized breakers / fuses / overcurrent protection switches, and wiring in accordance with local, state and NEC codes and requirements. The equipment installer is responsible for understanding and abiding by applicable codes and requirements.

iii

     Clamp electrical wires securely with a cable clamp after all wiring is connected to the terminal block. 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 clean with, or pour water, into the controller as it could cause electric shock and/or damage the unit. Do not use strong detergent such as a solvent. Clean with a soft cloth.

Check that the ground wire is securely connected. Do not connect ground wiring to gas piping, water piping, lighting conductor, or telephone ground wiring.
