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).

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 instructions as needed.

● This system should be installed by personnel certied by Johnson Controls, Inc. 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 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 correctly, injuries may occur due to a falling unit.

● Use appropriate Personal Protective Equipment (PPE), such as gloves and protective goggles and, where appropriate, have a gas mask nearby. Also use electrical protection equipment and tools suited

for electrical operation purposes. Keep a wet cloth and a re extinguisher nearby during brazing. Use

care in handling, rigging, and setting of bulky equipment.

● When transporting, be careful when picking up, moving and mounting these units. Although the unit may be packed using plastic straps, do not use them for transporting the unit from one location to another. Do not stand on or put any material on the unit. Get a partner to help, and bend with

your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum ns on the air conditioner can cut ngers, so wear protective gloves.

● 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 or switch.

● Johnson Controls 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 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 certications. ◦ May violate OSHA standards.

TC-16005-rev.2

Take the following precautions to reduce the risk of property damage.

● Be careful that moisture, dust, or variant refrigerant compounds not enter the refrigerant cycle during installation work. Foreign matter could damage internal components or cause blockages.

● If air lters are required on this unit, do not operate the unit without the air lter set in place. If the air

lter is not installed, dust may accumulate and breakdown may result.

● Do not install this unit in any place where silicon gases can coalesce. If the silicon gas molecules attach themselves to the surface of the heat exchanger, the nned surfaces will repel water. As a result, any amount of drainage moisture condensate can overow from the condensate pan and could

run inside of the electrical box, possibly causing electrical failures.

● 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 electronic interference 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 may cause the unit to malfunction. The operation of the unit may also adversely affect these same devices. Install the unit at least 10 ft. (approximately 3m) away from such devices.

● When a wireless controller is used, locate at a distance of at least 3.3 ft. (approximately 1m) between

the indoor unit and electric lighting. If not, the receiver part of the unit may have difculty receiving

operation commands.

● Do not install the unit in any location where animals and plants can come into direct contact with the outlet air stream. Exposure could adversely affect the animals and plants.

● Do not install the unit with any downward slope to the side of the condensate pipe. If you do, you may

have drain water owing back which may cause leaks.

● Be sure the condensate hose discharges water properly. If connected incorrectly, it may cause leaks.

● Do not install the unit in any place where oil can seep onto the units, such as table or seating areas in restaurants, and so forth. For these locations or social venues, use specialized units with oil-resistant features built into them. In addition, use a specialized ceiling fan designed for restaurant use. These specialized oil-resistant units can be ordered for such applications. However, in places where large quantities of oil can splash onto the unit, such as a factory, even the specialized units cannot be used. These products should not be installed in such locations.

● If the wired controller is installed in a location where electromagnetic radiation 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

operational temperature boundary in the manual. If there is no specied temperature, use the unit

within the operational temperature boundary of 32 to 104°F (0 to 40°C).

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

TC-16005-rev.2

Installation Precautions

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

● When installing the unit into…

◦ A wall: Make sure the wall is strong enough to hold the unit’s weight. It may be necessary to

construct a strong wood or metal frame to provide added support.

◦ A room: Properly insulate any refrigerant tubing run inside a room to prevent “sweating” that can

cause dripping and water damage to wall and oors.

◦ Damp or uneven areas: Use a raised concrete pad or concrete blocks to provide a solid, level

foundation for the unit to prevent water damage and abnormal vibration.

◦ An area with high winds: Securely anchor the outdoor unit down with bolts and a metal frame.

Provide a suitable wind bafe.

◦ A snowy area: Install the outdoor unit on a raised platform that is higher than drifting snow.

Provide snow protection hood.

● 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 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.

● Do not install the unit in the following places. Doing so can result in an explosion, re, deformation, corrosion, or product failure.

◦ Explosive or ammable atmosphere. ◦ Where re, oil, steam, or powder can directly enter the unit, such as in close proximity or directly

above a kitchen stove. ◦ Where oil (including machinery oil) may be present. ◦ Where corrosive gases such as chlorine, bromine, or sulde can accumulate, such as near a hot

tub or hot spring. ◦ Where dense, salt-laden airow is heavy, such as in coastal regions. ◦ Where the air quality is of high acidity. ◦ Where harmful gases can be generated from decomposition.

● Do not position the condensate pipe for the indoor unit near any sanitary sewers where corrosive gases may be present. If you do, toxic gases can seep into breathable air spaces and can cause respiratory injuries. If the condensate pipe is installed incorrectly, water leakage and damage to the

ceiling, oor, furniture, or other possessions may result. If condensate piping becomes clogged,

moisture can back up and can drip from the indoor unit. Do not install the indoor unit where such dripping can cause moisture damage or uneven locations: Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the unit to prevent water damage and abnormal vibration.

● Before performing any brazing work, be sure that there are no ammable materials or open ames nearby.

● Perform a test run to ensure normal operation. Safety guards, shields, barriers, covers, and protective

devices must be in place while the compressor/unit is operating. During the test run, keep ngers and

clothing away from any moving parts.

● Clean up the site when nished, remembering to check that no metal scraps or bits of wiring have been left inside the unit being installed.

● During transportation, do not allow the backrest of the forklift make contact with the unit, otherwise, it may cause damage to the heat exchanger and also may cause injury when stopped or started suddenly.

● Remove gas inside the closing pipe when the brazing work is performed. If the brazing ller metal is melted with remaining gas inside, the pipes will be blown off and it may cause injury.

● Be sure to use nitrogen gas for an airtight test. If other gases such as oxygen gas, acetylene gas or

uorocarbon gas are accidentally used, it may cause explosion or gas intoxication.

After installation work for the system has been completed, explain the “Safety Precautions,” the proper use and maintenance of the unit to the customer according to the information in all manuals that came with the system. All manuals and warranty information must be given to the user or left near the Indoor Unit.

TC-16005-rev.2

Refrigerant Precautions

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

● As originally manufactured, this unit contains refrigerant installed by Johnson Controls. Johnson

Controls uses only refrigerants that have been approved for use in the unit’s intended home country or market. Johnson Controls distributors similarly are only authorized to provide refrigerants that

have been approved for use in the countries or markets they serve. The refrigerant used in this unit

is identied on the unit’s faceplate and/or in the associated manuals. Any additions of refrigerant into this unit must comply with the country’s requirements with regard to refrigerant use and should be obtained from Johnson Controls distributors. Use of any non-approved refrigerant substitutes will void

the warranty and will increase the potential risk of injury or death.

● If installed in a small room, take measures to prevent the refrigerant from exceeding the maximum allowable concentration in the event that refrigerant gases should escape. The installation should meet the requirements in ASHRAE Standards 15 and 34. If refrigerant gas has leaked during the installation work, ventilate the room immediately.

● Check the design pressure for this product is 601 psi (4.15MPa). The pressure of the refrigerant R410A is 1.4 times higher than that of the refrigerant R22. Therefore, the refrigerant piping for

R410A shall be thicker than that for R22. Make sure to use the specied refrigerant piping. If not, the

refrigerant piping may rapture due to an excessive refrigerant pressure. Besides, pay attention to the piping thickness when using copper refrigerant piping. The thickness of copper refrigerant piping differs depending on its material.

● The refrigerant R410A is adopted. The refrigerant oil tends to be affected by foreign matters such

as moisture, oxide lm, (or fat). Perform the installation work with care to prevent moisture, dust, or

different refrigerant from entering the refrigerant cycle. Foreign matter can be introduced into the cycle from such parts as expansion valve and the operation may be unavailable.

● To avoid the possibility of different refrigerant or refrigerant oil being introduced into the cycle, the sizes of the charging connections have been changed from R407C type and R22 type. It is necessary to prepare the appropriate tools before performing installation work.

● Use refrigerant pipes and joints which are approved for use with R410A.

● A compressor/unit comprises a pressurized system. Never loosen threaded joints while the system is under pressure and never open pressurized system parts.

● Before installation is complete, make sure that the refrigerant leak test has been performed. If

refrigerant gases escape into the air, turn OFF the main switch, extinguish any open ames and

contact your service contractor. Refrigerant (Fluorocarbon) for this unit is odorless. If the refrigerant

should leak and come into contact with open ames, toxic gas could be generated. Also, because the uorocarbons are heavier than air, they settle to the oor, which could cause asphyxiation.

● When installing the unit, and connecting refrigerant piping, keep all piping runs as short as possible, and make sure to securely connect the refrigerant piping before the compressor starts operating. If the refrigerant piping is not connected and the compressor activates with the stop valve opened, the refrigerant cycle will become subjected to extremely high pressure, which can

cause an explosion or re.

● Tighten the are nut with a torque wrench in the specied manner. Do not apply excessive force to the are nut when tightening. If you do, the are nut can crack and refrigerant leakage may occur.

● When maintaining, relocating, and disposing of the unit, dismantle the refrigerant piping after the compressor stops.

● When pipes are removed out from under the piping cover, after the insulation work is completed,

cover the gap between the piping cover and pipes by a packing (eld-supplied). If the gap is not

covered, the unit may be damaged if snow, rain water or small animals enter the unit.

● Do not apply an excessive force to the spindle valve at the end of opening. Otherwise, the spindle

valve ies out due to refrigerant pressure. At the test run, fully open the gas and liquid valves,

otherwise, these devices will be damaged. (It is closed before shipment.)

● If the arrangement for outdoor units is incorrect, it may cause owback of the refrigerant and result in failure of the outdoor unit.

● The refrigerant system may be damaged if the slope of the piping connection kit exceeds +15

TC-16005-rev.2

Electrical Precautions

Take the following precautions to reduce the risk of electric shock, re or

explosion resulting in serious injury or death.

● Highly dangerous electrical voltages are 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.

● Perform all electrical work in strict accordance with this installation and maintenance manual and all the relevant regulatory standards.

● Before servicing, open and tag all disconnect switches. Never assume electrical power is disconnected. Check with meter and equipment.

● Only use electrical protection equipment and tools suited for this installation.

● Insulate a wired controller against moisture and temperature extremes.

● Use specied cables between units.

● The new air conditioner may not function normally in the following instances:

◦ If electrical power for the new air conditioner is supplied from the same transformer as the

external equipment* referred to below.

◦ If the power source cables for this external equipment* and the new air conditioner unit are

located in close proximity to each other.

external equipment*: (Example): A lift, container crane, rectier for electric railway, inverter power device, arc furnace, electric furnace, large-sized induction motor and large-sized switch.

Regarding the cases mentioned above, surge voltage may be inducted into the power supply cables for the packaged air conditioner due to a rapid change in power consumption of the device and an activation of a switch.

Check eld regulations and standards before performing electrical work in order to protect the

power supply for the new air conditioner unit.

● Communication cabling shall be a minimum of AWG18 (0.82mm

), 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 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.

● Use an exclusive power supply for the air conditioner at the unit’s rated voltage.

● 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 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 the controller or cables to indoor or outdoor units, open and tag all disconnect switches. Never assume electrical power is disconnected. Check with a meter and equipment.

● 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.

For twin, triple or quad combinations, a communication cable for the wireless controller is not required.

Wired Controller Cable

Use the field-supplied communication cable (AWG18) for the wired controller cable. The total length should be within 1640ft (500m). If the total length is less than 98ft (30m), AWG22 cables can be used.

Do not run the connected wireless controller cable and the power supply cable (208/230V) in parallel in

the indoor units. Stabilize the cable with cable bands. Along with the wiring outside the indoor units, the control cables

should not run with the power supply cable (208/230V). Keep a separation of more than 12 inches (30cm)

or run the cable through a grounded metal conduit.

Unit Number Setting

The indoor unit numbers are set by the auto-address function. Therefore, an indoor unit number setting

is not required. If the indoor unit number is xed, set the unit number of all indoor units respectively and serially. It is recommended that the unit number settings begin with “1”. The setting is set not to overlap

the unit number.

3.3.11 Test Run by Wireless Controller (CIR01)

After all installations are completed, a test run should be performed.

(1) Perform the test run according to the Installation Manual of the wireless controller.

(2) The test run from the wireless controller switch takes two hours to complete.

NOTE:

For the wall mount indoor units, if the TIMER indicator (green) is ashing (0.5 second ON/0.5 second

OFF) after two hours, an alarm may occur. Operate the indoor unit ,and check for abnormality.

3.3.12 Alarm Indication

● If a malfunction occurs, such as safety device actuation, during the test run or the normal operation, “RUN” (red light) ashes (0.5 second ON / 0.5 second OFF).

● The alarm codes are indicated by the number of LED ashes of “DEF” (green light) and “FILTER” (yellow

light).

The rst LED light is green. The number of times this LED ashes (0.5 second ON and

OFF) will tell you the “DEF” Alarm Code.

The second LED light is yellow. The number of times this LED ashes (0.5 second ON and

OFF) will tell you the “FILTER” Alarm Code.

Example

"FILTER" (yellow light)

"DEF" (green light)

"DEF" flashes three times (0.5 second ON/ 0.5 second OFF)

"FILTER" flashes five times (0.5 second ON/ 0.5 second OFF

● ”RUN” (red light) ashing (1 second ON/1 second OFF) indicates an abnormal transmission (connector

loose, connector disconnection, broken wire, or incorrect wiring, or something similar) between the indoor unit and the IR receiver kit.

● When the IR receiver kit is connected to multiple indoor units, the alarm code is indicated for each

indoor unit in order.

Alarm Code Table

Further details for alarm codes can be found in the “Installation and Maintenance Manual” for the indoor unit.
