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 certied by Johnson Controls, Inc. Personnel must be
qualied 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 specied, 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.

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 overow 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 difculty 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 adaptor. 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 specied 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 wall for wind prevention (eld-supplied). Or install Wind Guard (optional).
◦A snowy area: Install the outdoor unit on a raised platform that is higher than drifting snow.
Provide snow roof for snow prevention (eld-supplied). Or install Snow Protection Hood (optional).
●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 sulde can accumulate, such as near a hot
tub or hot spring.
◦Where dense, salt-laden airow 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 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. Do not position the drain pipe for the indoor unit near
any sanitary sewers where corrosive gases may be present.
●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-16001-rev.5
iii
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 identied 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
3
(0.42 kg/m3) 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 specied refrigerant piping. If not, the
refrigerant piping may rupture 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 specied 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

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 specied 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, rectier 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
), 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.
