This manual should be considered as a permanent part of the air conditioning equipment and should remain with the air conditioning equipment. (Transportation/Installation Work) > (Refrigerant Piping Work) > (Electrical Wiring Work) > (Ref. Charge Work) > (Test Run) > (User) 2. Important Safety Instructions Signal Words 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 (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 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. In areas where Seismic ‘’Performance requirements are specified, 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 fire extinguisher nearby during brazing. Use care in handling, rigging, and setting of bulky equipment. - Page 4 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 filters are required on this unit, do not operate the unit without the air filter set in place. If the air filter 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 finned surfaces will repel water. As a result, any amount of drainage moisture condensate can overflow 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 difficulty 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 flowing 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.

Page 5: Installation Precautions
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 floors. ◦ 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 baffle. ◦ 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, fire, deformation, corrosion, or product failure. ◦ Explosive or flammable atmosphere. ◦ Where fire, oil, steam, or powder can directly enter the unit, such as in close proximity or directly above a kitchen stove. -
Page 6: Refrigerant Precautions
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 identified 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 specified 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 film, (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. - Page 7 Electrical Precautions Take the following precautions to reduce the risk of electric shock, fire 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 specified 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, rectifier 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 field 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.
