10 Introduction ESIE Safety Cautions Cautions and warnings Be sure to read the following safety cautions before conducting repair work. The caution items are classified into Warning and Caution. The Warning items are especially important since they can lead to death or serious injury if they are not followed closely. The Caution items can also lead to serious accidents under some conditions if they are not followed. Therefore, be sure to observe all the safety caution items described below. About the pictograms This symbol indicates an item for which caution must be exercised. The pictogram shows the item to which attention must be paid. This symbol indicates a prohibited action. The prohibited item or action is shown inside or near the symbol. This symbol indicates an action that must be taken, or an instruction. The instruction is shown inside or near the symbol. After the repair work is complete, be sure to conduct a test operation to ensure that the equipment operates normally, and explain the cautions for operating the product to the customer..2. Caution in Repair Warning Warning Be sure to disconnect the power cable plug from the plug socket before disassembling the equipment for a repair. Working on the equipment that is connected to a power supply can cause an electrical shook. If it is necessary to supply power to the equipment to conduct the repair or inspecting the circuits, do not touch any electrically charged sections of the equipment. If the refrigerant gas discharges during the repair work, do not touch the discharging refrigerant gas. The refrigerant gas can cause frostbite. When disconnecting the suction or discharge pipe of the compressor at the welded section, release the refrigerant gas completely at a well-ventilated place first. If there is a gas remaining inside the compressor, the refrigerant gas or refrigerating machine oil discharges when the pipe is disconnected, and it can cause injury. If the refrigerant gas leaks during the repair work, ventilate the area. The refrigerant gas can generate toxic gases when it contacts flames. ii

11 ESIE08-0 Introduction Warning The step-up capacitor supplies high-voltage electricity to the electrical components of the outdoor unit. Be sure to discharge the capacitor completely before conducting repair work. A charged capacitor can cause an electrical shock. Do not start or stop the air conditioner operation by plugging or unplugging the power cable plug. Plugging or unplugging the power cable plug to operate the equipment can cause an electrical shock or fire. Caution Caution Do not repair the electrical components with wet hands. Working on the equipment with wet hands can cause an electrical shock. Do not clean the air conditioner by splashing water. Washing the unit with water can cause an electrical shock. Be sure to provide the grounding when repairing the equipment in a humid or wet place, to avoid electrical shocks. Be sure to turn off the power switch and unplug the power cable when cleaning the equipment. The internal fan rotates at a high speed, and cause injury. Do not tilt the unit when removing it. The water inside the unit can spill and wet the furniture and floor. Be sure to check that the refrigerating cycle section has cooled down sufficiently before conducting repair work. Working on the unit when the refrigerating cycle section is hot can cause burns. Use the welder in a well-ventilated place. Using the welder in an enclosed room can cause oxygen deficiency. iii

12 Introduction ESIE Cautions Regarding Products after Repair Warning Warning Be sure to use parts listed in the service parts list of the applicable model and appropriate tools to conduct repair work. Never attempt to modify the equipment. The use of inappropriate parts or tools can cause an electrical shock, excessive heat generation or fire. When relocating the equipment, make sure that the new installation site has sufficient strength to withstand the weight of the equipment. If the installation site does not have sufficient strength and if the installation work is not conducted securely, the equipment can fall and cause injury. Be sure to install the product correctly by using the provided standard installation frame. Incorrect use of the installation frame and improper installation can cause the equipment to fall, resulting in injury. Be sure to install the product securely in the installation frame mounted on a window frame. If the unit is not securely mounted, it can fall and cause injury. Be sure to use an exclusive power circuit for the equipment, and follow the technical standards related to the electrical equipment, the internal wiring regulations and the instruction manual for installation when conducting electrical work. Insufficient power circuit capacity and improper electrical work can cause an electrical shock or fire. Be sure to use the specified cable to connect between the indoor and outdoor units. Make the connections securely and route the cable properly so that there is no force pulling the cable at the connection terminals. Improper connections can cause excessive heat generation or fire. When connecting the cable between the indoor and outdoor units, make sure that the terminal cover does not lift off or dismount because of the cable. If the cover is not mounted properly, the terminal connection section can cause an electrical shock, excessive heat generation or fire. Do not damage or modify the power cable. Damaged or modified power cable can cause an electrical shock or fire. Placing heavy items on the power cable, and heating or pulling the power cable can damage the cable. For integral units only For integral units only Do not mix air or gas other than the specified refrigerant (R-0A) in the refrigerant system. If air enters the refrigerating system, an excessively high pressure results, causing equipment damage and injury. If the refrigerant gas leaks, be sure to locate the leak and repair it before charging the refrigerant. After charging refrigerant, make sure that there is no refrigerant leak. If the leak cannot be located and the repair work must be stopped, be sure to perform pump-down and close the service valve, to prevent the refrigerant gas from leaking into the room. The refrigerant gas itself is harmless, but it can generate toxic gases when it contacts flames, such as fan and other heaters, stoves and ranges. iv

13 ESIE08-0 Introduction Warning When replacing the coin battery in the remote controller, be sure to disposed of the old battery to prevent children from swallowing it. If a child swallows the coin battery, see a doctor immediately. Cautions Caution Installation of a leakage breaker is necessary in some cases depending on the conditions of the installation site, to prevent electrical shocks. Do not install the equipment in a place where there is a possibility of combustible gas leaks. If a combustible gas leaks and remains around the unit, it can cause a fire. Be sure to install the packing and seal on the installation frame properly. If the packing and seal are not installed properly, water can enter the room and wet the furniture and floor. For integral units only.2. Inspection after Repair Warning Warning Check to make sure that the power cable plug is not dirty or loose, then insert the plug into a power outlet all the way. If the plug has dust or loose connection, it can cause an electrical shock or fire. If the power cable and lead wires have scratches or deteriorated, be sure to replace them. Damaged cable and wires can cause an electrical shock, excessive heat generation or fire. Do not use a joined power cable or extension cable, or share the same power outlet with other electrical appliances, since it can cause an electrical shock, excessive heat generation or fire. v

14 Introduction ESIE08-0 Caution Caution Check to see if the parts and wires are mounted and connected properly, and if the connections at the soldered or crimped terminals are secure. Improper installation and connections can cause excessive heat generation, fire or an electrical shock. If the installation platform or frame has corroded, replace it. Corroded installation platform or frame can cause the unit to fall, resulting in injury. Check the grounding, and repair it if the equipment is not properly grounded. Improper grounding can cause an electrical shock. Be sure to measure the insulation resistance after the repair, and make sure that the resistance is Mohm or higher. Faulty insulation can cause an electrical shock. Be sure to check the drainage of the hydro-box after the repair. Faulty drainage can cause the water to enter the room and wet the furniture and floor. vi

19 ESIE08-0 Introduction..2 Refrigerant Cylinders Cylinder specifications The cylinder is painted refrigerant color (pink). The cylinder valve is equipped with a siphon tube. Cylinder Siphon tube Handling of cylinders Note: Refrigerant can be charged in liquid state with cylinder in upright position. Caution!: Do not lay cylinder on its side during charging, since it causes refrigerant in gas state to enter the system. Laws and regulations R0A is liquefied gas, and the High-Pressure Gas Safety Law must be observed in handling them. Before using, refer to the High-Pressure Gas Safety Law. The Law stipulates standards and regulations that must be followed to prevent accidents with high-pressure gases. Be sure to follow the regulations. 2 Handing of vessels Since R0A is high-pressure gas, it is contained in high-pressure vessels. Although those vessels are durable and strong, careless handling can cause damage that can lead to unexpected accidents. Do not drop vessels, let them fall, apply impact or roll them on the ground. Storage Although R0A is not flammable, it must be stored in a well-ventilated, cool, and dark place in the same way as any other high-pressure gases. It should also be noted that high-pressure vessels are equipped with safety devices that releases gas when the ambient temperature reaches more than a certain level (fusible plug melts) and when the pressure exceeds a certain level (spring-type safety valve operates). xi

20 Introduction ESIE Service Tools R0A is used under higher working pressure, compared to previous refrigerants (R22,R07C). Furthermore, the refrigerating machine oil has been changed from Suniso oil to Ether oil, and if oil mixing is occurred, sludge results in the refrigerants and causes other problems. Therefore, gauge manifolds and charge hoses that are used with a previous refrigerant (R22,R07C) can not be used for products that use new refrigerants. Be sure to use dedicated tools and devices. Tool compatibility Compatibility Tool Gauge manifold Charge hose Charging cylinder Gas detector Vacuum pump (pump with reverse flow preventive function) Weighting instrument Charge mouthpiece Flaring tool (Clutch type) HFC HCFC R0A R07C R22 X O X O O X O O X Reasons for change Do not use the same tools for R22 and R0A. Thread specification differs for R0A and R07C. Weighting instrument used for HFCs. The same tool can be used for HFCs. To use existing pump for HFCs, vacuum pump adaptor must be installed.
