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 safety instructions as needed. ● This system, including Remote Access, should be installed by personnel certified by HITACHI. 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 product is not installed correctly, injuries may occur due to a falling product. ● 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 fire 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.
- Page 6 ● When installing Central Station EX 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 product to malfunction. The operation of the product may also adversely affect these same devices. Install the product at least 3m away from such devices. ● When a wireless controller is used, locate it at a distance of at least 1 meter 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 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 Take the following precautions to reduce the risk of electric shock, fire or explosion resulting in serious injury or death: ● When installing Central Station EX into… ▫ A wall: Make sure the wall is strong enough to hold the product’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. ● Do not install Central Station EX in the following places. Doing so can result in an explosion, fire, damage, corrosion, or product failure. ▫ Explosive or flammable atmosphere ▫ Where a fire, oil, steam or powder can directly enter the unit, such as nearby or above a kitchen stove.
- 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. ● Before servicing, open and tag all disconnect switches. Never assume that electrical power is disconnected. Check with meter and equipment. ● Only use electrical protection equipment and tools suited for this installation. ● Use specified cables between Central Station EX and the power supply/air conditioner/external equipment. ● Shielded communication cable is not always required but strongly recommended to prevent communication issues for applications such as: Heavy and Light Industrial Buildings, Telecom Centers, Data Centers, Airports, Radio Stations, Hospitals/Healthcare buildings, and Offices. ● Use a dedicated 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 specified capacity. Ensure that the wiring terminals are tightened securely to recommended torque specifications. ● 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. ● Turn OFF and disconnect Central Station EX from the power source when wiring. Do not open the back cover without turning OFF the main power supply. ● Do not clean with, or pour water into, Central Station EX as it could cause electric shock and/or damage the product. Do not use strong detergent such as a solvent. Clean with a soft cloth.
