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. 1.1.1 Caution in Repair 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. 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. 1 Domestic Air Conditioner Introduction Warning 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. 1.1.2 Cautions Regarding Products after Repair 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. For Incorrect use of the installation frame and improper installation can cause the equipment to fall, resulting in injury. integral units only 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. 2 For integral units only Domestic Air Conditioner Introduction Warning 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. Do not mix air or gas other than the specified refrigerant (R-410A / R22) 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. 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. 3 Domestic Air Conditioner Introduction 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 1.1.3 Inspection after Repair 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. Warning 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. 4 Introduction 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 1 M ohm or higher. Faulty insulation can cause an electrical shock. Be sure to check the drainage of the indoor unit after the repair. Faulty drainage can cause the water to enter the room and wet the furniture and floor. 5 Domestic Air Conditioner 2 List of fuctions Functions Category Y/N Child lock Avoid the child's wrong operation on the remote controller Y 3D air flow The 3D airflow is able to deliver the airflow horizontally and vertically.

Coldair proof operation 1. The indoor operation within 4 minutes after the start up is as the following diagram, the air speed can be raised only after the speed has reached a certain level. Set speed Heat start temp 1 Low speed Keep the high Heat start temp 2 speed. The fan Light speed doesn’t stop Heat start temp 3 Fan/off Heat start temp 4 Fan/off 2. 4 minutes after the start up of the indoor fan, the light airflow and the low airflow will be turned to the set speed airflow. 3. In the cold air proof operation, the fan won’t stop after the start up. 4. During the cold air proof operation, the indoor system will continuously send ‘indoor high speed’ signals to the outdoor system. * Residue heat sending. The indoor fan will send the residue heat at a low speed for 12 seconds. If other conditions are satisfied, when the compressor stops, the indoor system will operate at a light speed. The indoor fan will stop when the coil temperature is below the ‘heat start temp 4’. * Defrosting. When the system receives the defrosting signal from outdoors, the indoor fan will stop and the indoor temperature display won’t change. At the time, any indoor coil malfunctions will be neglected. When the outdoor defrosting finishes, the coil malfunction will still be neglected until the compressor has been started up for 30 seconds. The indoor temperature display will not change and the system operates at the cold air proof mode. * Automatic heating temperature compensation: when the system enters the heating mode, the temperature compensation (4) will be added. When the status is switched off, the compensation will be erased. 5.1.5 Strength operation The system enters the mode after receiving the ‘strength signal’. Send strength operation signal to the outdoor system. The mode change finishes the strength operation. Entering ‘mute’, you can have normal operation or signal control such as timing to finish the strength operation. 16 Domestic Air Conditioner Functions and control When the system is at the automatic option with the strength/ mute function, if the system enters the cooling mode, the cooling strength/ mute function will be offered; if the system enters the heating mode, then the heating strength/ mute function will be offered; if the system enters the airflow mode, there will be no strength/ mute function. 5.1.6 Mute operation The system enters the mode after receiving the ‘mute signal’. a. Mute heating: the airflow speed is slight, the system sends the mute signal to the outdoor system. b. mute cooling: the airflow speed is slight, the system sends the mute signal to the outdoor system. When the compressor operates, the airflow speed is mute speed. EEPROM is adaptable. Mute operation can not work under the dehumidifying and airflow-sending operation. 5.1.7 Air refreshing After receiving the signal from the remote control, (HV series: the background light of the ‘health’ logo is green. HS series: the ‘health’ indicator will be lighted). If the fan operates, the Nano-Aqua operates to realize the ions sending function. If the indoor fan stops, the Nano-Aqua is turned off. When the Nano-Aqua is turned off, if the air refreshing system is turned on, the Nano-Aqua will be turned on when the fan operates. 5.1.8 Timing You can set 24 hours’ on/off timing accordingly. After the setting, the timing indicator will be lightened. Also, the light will be turning off after the timing is finished. The followings are several timing methods. 1.system /on timing: The timing indicator will be lightened and the indoor system is under the waiting mode. The light will be turned off when the timing is finished and the rest of the system will operate under a normal condition. The timing starts since the last reception of the timing signal. 2.system /off timing: When the system is turned on, the timing indicator is lightened, the rest of the system will operated under a normal condition. When set time comes, the indicator light will be turned off and the system will be turned off. If you have set the dormant functions, the order of your settings will be operated according to the timing settings. 3 .system /on and off timing: The settings will be completed according to the orders.. 5.1.9 Dormant operation The dormant timing is an eight hours unadaptable one. The timing signs are shown on the V series board. (RC series show the dormant signal, the timing light is lighted on the 6 lights board). 2.1 Under the cooling/ dehumidifying operation, after the setting of the dormant operation, the set temperature will be raised for 1 centigrade after 1 hour’s operation and will be raised for 1 centigrade 1 hour later. The system will keep this status for 6 hours and then close. 2.2 Under the heating mode, after the setting of the dormant operation, the setting temperature will fall 2 centigrade after 1 hour’s operation and will fall 2 centigrade 1 hour later. 3 hours after the preceding 17 Domestic Air Conditioner Functions and control operations, the set temperature will be raised for 1 centigrade and the system will keep this status for 3 hours and then close down. 2.3 During the dormant time, except the change of the system mode or a new press on the dormant setting keys, the timing of the 8 hours dormancy will take the first timing as the start time, any presses on other keys will not affect the original timing. 2.4 Indoor fan control under the dormant operation. If the indoor fan is at the high speed before the dormant operation setting, the speed will be turned to medium after the setting. If the fan is at the medium speed before the dormant setting, the speed will be turned to low after the setting. If the fan is at the low speed before the dormant setting, the speed will not change. 5.1.10 Urgent on/off input Press the urgency button the buzzer will ring.
