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
safety 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

4P5415467
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 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 zone controller is used, locate at a distance of at least 3.3 ft. (approximately 1 meter)
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
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.
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.
● 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.
ii

5P5415467
●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 run test 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 to 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.
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 (0.42 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.
●The design pressure for this product is 601 psi (4.15MPa). The pressure of R410A refrigerant 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 specified 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 the 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
iii

6P5415467
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 run test, 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 +15o.
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.
● 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 conditioning unit 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.
iv

7P5415467
●Communication cabling shall 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 guidelines. Plenum and riser ratings for communication cables must be considered per
application and local code requirments.
● Use an exclusive power supply for the air conditioner at the unit’s rated voltage.
●Be sure to install circuit breakers (ground fault interrupter, isolating switch, molded case circuit
breaker and so on), with the specied capacity. Ensure that the wiring terminals are tightened securely
to recommended torque specications.
●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.
●Turn OFF and disconnect the unit from the power source when handling the service connector. Do not
open the service cover or access panel to the indoor or outdoor units without turning OFF the main
power supply.
● After ceasing operation, be sure to wait at least ve minutes before turning off the main power
switch. Otherwise, water leakage or electrical breakdown may result. Disconnect the power source
completely before attempting any maintenance for electrical parts. Check to ensure that no residual
voltage is present after disconnecting the power source.
●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.
●If a circuit breaker or fuse is frequently activated, shut down the system and contact your
service contractor.
●Perform all electrical work in accordance with this manual and in compliance with all regulations and
safety standards.
● Do not open a service access cover or panel of an indoor or outdoor unit without rst turning OFF the
power at the main power supply.
●Residual voltage can cause electric shock. At all times, check for residual voltage after disconnecting
from the power source before starting work on the unit.
●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.

Installation and Maintenance
There are high-capacity electrolytic capacitors on the outdoor mainboard. Thus, even if the power is cut off, there is high voltage inside
the capacitors and it needs more than 20 min. to reduce the voltage to safety value. Touching the electrolytic capacitor within 20 min.
after cutting the power will cause electric shock. If maintenance is needed, follow the steps below to discharge electricity of electrolytic
capacitor after power off.
(1) Open the top cover of outdoor unit and then remove the cover of the electric box.
(2) After finishing discharging electricity, measure the voltage between points A and B with universal meter to make sure if electricity
discharging is completed, in order to prevent electric shock. If the voltage between the two points is below 20V, you can perform
maintenance safely.
