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 quenching 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-16004-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 drain 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 drain boss. If you do, you may have

drain water owing back which may cause leaks.

● Be sure the drain 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 35 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.

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 air bafe.

◦ A snowy area (only for Heat Pump Model): Install the outdoor unit on a raised platform that is

higher than drifting snow. Provide snow vents.

● 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 drain 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 drainpipe 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-16004-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. Refrigerant gases can

cause asphyxiation (0.026 lbs/ft

(0.42 kg/m

) based on ISO 5149 for R410A). Consult with your

distributor for countermeasures (ventilation system and so on). 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-16004-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 device*

referred to below.

◦ If the power source cables for this device* and the new air conditioner unit are located in close

proximity to each other.

Device*: (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.

VRF Air Conditioners

Johnson Controls proudly introduces new Variable Refrigerant Flow (VRF) air conditioners, a highly-efcient

and reliable air-conditioning system. Recently, increased numbers of buildings are requiring "intelligent"

facilities that include communication networks, ofce automation, and a comfortable environment. In

particular, a comfortable environment is becoming more of a year-around requirement in ofce buildings.

The VRF multi-split system air conditioner meets these requirements. The proven combination of the scroll

compressor and inverter provides the best air conditioning for small and medium ofce buildings.

■ VRF System

Johnson Controls has developed the VRF system with its customers in mind.

This system, which is unique in the world, allows the interconnection of indoor units for all our VRF air

conditioners.

This system provides the consumer with greater exibility for installation, which means that the air-

conditioning systems will integrate better within complex facility structures.

● Improvement of Energy-Saving

Air renewal has a downside of increased energy consumption. These models save energy while renewing

room air and reducing levels of CO

while also eliminating unpleasant smells, smoke and pollution.

(1) Supplies fresh new air into the room while keeping the correct indoor temperature, and also provides

natural cooling for increased energy saving (reducing energy consumption).

(2) Allows inow of fresh air into the room through the indoor unit, even when the thermostat is switched

off (Thermo-OFF*). Depending on the supply air and outlet air temperatures, this unit works like an

intelligent system, controlling the air ow by modifying the position of the damper.

NOTE:

Thermo-On: The outdoor unit and some indoor units are running.

Thermo-OFF: The outdoor unit and some indoor units stay on, but don’t run.

(3) Effectively increases the installation performance when the outdoor temperature is lower than the

room temperature (in cooling mode), allowing the inlet of fresh air and cooling to the set temperature

without activating the outdoor unit. For example, it can supply up to 100% of fresh air and is able to

provide “natural cooling” through a damper when the outdoor temperature is lower than the set indoor

temperature (in cooling mode), leading to signicant energy savings particularly in spring and autumn.

(4) EconoFresh can operate with CO

or enthalpy sensors to control the air quality in the room.

NOTE:

The enthalpy sensor and CO

gas sensor cannot be installed together.

The enthalpy sensor and CO

gas sensor have no effect on the EconoFresh operation when the All

Fresh process is activated.

TC-16004-rev.2

● Damper Control

The EconoFresh kit is equipped with an outdoor air damper control mechanism, and the system provides

various operation modes, such as free cooling, all fresh, in cooling and heating mode.

A micro-computer controls the angle of the damper according to air temperatures to adjust the fresh air

ow, thus keeping the room temperature constant with excellent comfort.

Selectable Minimum Damper Opening

The minimum opening for fresh outdoor air damper is selectable through the wired controller (d7 optional

function setting). This allows establishing a minimum air volume renewal in the room.

● Standard and All Fresh Process Modes

Two different process modes are selectable:

(1) Standard Process

Standard Process in Cooling Mode

In a situation where the outdoor ambient temperature is lower than 66

F (19

C), the compressor stops and

the indoor temperature is cooled down with an intake of outdoor fresh cold air controlled by the damper.

The minimum guaranteed fresh air intake can be set through the d7 setting (7% or more of the total outlet

air).

• Cooling Economizer

An energy saving control is adopted which uses fresh cold air from the outdoors for cooling the

intermediate seasons. The compressor is not used during this control, which results in outstanding

energy saving.

• Three Different Economizer Cooling Controls

In order to optimize energy savings, EconoFresh can manage three types of control: normal cooling,

outdoor air cooling or fan cooling. Each type is managed according to the outdoor air temperature.

• Comfort Control

When Thermo OFF is requested, EconoFresh compares temperatures in order to offer a comfortable

environment in the room. EconoFresh control compares the set temperature (set in the wired controller)

and the inlet air temperature in the Indoor Unit, and requests Thermo ON under certain conditions, in

order to achieve the requested room temperature as soon as possible.

Standard Process in Heating Mode

Depending on the temperature of indoor air return, the damper remains either opened for a minimum

guaranteed intake of fresh air, or fully closed for 10 minutes. After this time, the damper is opened for a

minimum guaranteed intake of fresh air intake; this opening can be set through the d7 setting (7% or more

of the total outlet air).

(2) All Fresh Process in Cooling and Heating Mode

This operation mode is very useful for buildings with many tenants, or for public buildings.

Basically, the damper is fully opened (100% fresh air) when activated through the wired controller (E1

optional function setting).

The following parameters are controlled by the All Fresh process in an independent fashion:

* Thermo ON/OFF status

* Damper opening

* Fan speed

Thermo ON/OFF Status

The general principle is that the compressor remains stopped when the outdoor ambient temperature is

lower than 63

F (17

C) in cooling mode and higher than 75

F (24

C) in heating mode.

Damper Opening

The damper is set to be either fully open or closed to the minimum opening to ensure an intake of fresh air

(7% or more of the total outlet air, by the d7 setting).

Additionally, the damper is closed to the minimum opening to ensure an intake of fresh air, under certain

temperature combinations.

Fan Speed

The fan speed is adjusted one tap lower when the air outlet temperature...

* rises higher than 68

F (20

C) in cooling mode

* drops lower than 86

F (30

C) in heating mode

In the above cases, the fan speed is changed from high to medium, or from medium to low.

The fan speed is adjusted back to fan setting tap when air outlet temperature returns to the following

ranges:

* 59

F (15

C) or lower in cooling mode

* 95

F (35

C) or higher in heating mode

Draft Prevention Control

Additionally, while the All Fresh process is activated, the EconoFresh control keeps monitoring and

comparing several temperature parameters. The damper may be closed to the minimum opening to

ensure the intake of fresh air under certain circumstances, and in order to avoid discomfort and unwanted

changes to room temperature due to inlet outdoor air conditions.

This function is active if the outdoor ambient temperature is

* 9

F (5

C) higher than the setting temperature in cooling thermo-OFF

* 9

F (5

C) lower than the setting temperature in heating thermo-OFF

2.3 General Data

NOTES:

*1. Nominal capacity is based on combinations within the VRF system and the following conditions:

Cooling Operation Conditions Heating Operation Conditions

Indoor Air Inlet Temperature: 80°F DB (26.7°C DB) Indoor Air Inlet Temperature: 70°F DB (21.1°C DB)

67°F WB (19.4°C WB) Outdoor Air Inlet Temperature: 47°F DB (8.3°C DB)

Outdoor Air Inlet Temperature: 95°F DB (35.0°C DB) 43°F WB (6.1°C WB)

Piping Length: 24 ft. 7-3/16 in. (7.5m)

Piping Lift: 0 ft. (0m)

*2. The sound pressure level is based on the following conditions.

4.9 ft. (1.5m) beneath the unit, connection with the EconoFresh Kit, EconoFresh Pressure Mode Setting, damper opening

is OA 50% and RA 50%, at rated airow volume and lter is not used.

The above data was measured in an anechoic chamber so that reected sound should be taken into consideration in the

eld.

*3. The data for external pressure is based on a connection with the EconoFresh Kit (with a damper setting of maximum

pressure drop (damper opening at OA 100%)), EconoFresh Pressure Mode Setting and the lter is not used.
