APPLICATION DATA Safety precautions • When install the unit, be sure to check whether the selection of installation place, power supply specifications, usage limitation (piping length, height differences between indoor and outdoor units, power supply voltage and etc.) and installation spaces. • We recommend you to read this “SAFETY PRECAUTIONS” carefully before the installation work in order to gain full advantage of the functions of the unit and to avoid malfunction due to mishandling. • The precautions described below are divided into WARNING and CAUTION . The matters with possibilities leading to serious consequences such as death or serious personal injury due to erroneous handling are listed in the WARNING and the matters with possibilities leading to personal injury or damage of the unit due to erroneous handling including probability leading to serious consequences in some cases are listed in CAUTION . These are very important precautions for safety. Be sure to observe all of them without fail. • Be sure to confirm no anomaly on the equipment by commissioning after completed installation and explain the operating methods as well as the maintenance methods of this equipment to the user according to the owner’s manual. • Keep the installation manual together with owner’s manual at a place where any user can read at any time. Moreover if necessary, ask to hand them to a new user. • For installing qualified personnel, take precautions in respect to themselves by using suitable protective clothing, groves, etc., and then perform the installation works. • Please pay attention not to fall down the tools, etc. when installing the unit at the high position. • If unusual noise can be heard during operation, consult the dealer. • Symbols which appear frequently in the text have the following meaning: Observe instructions with great care Strictly prohibited Provide proper earthing WARNING • Installation must be carried out by the qualified installer. If you install the system by yourself, it may cause serious trouble such as water leaks, electric shocks, fire and personal injury, as a result of a system malfunction. • Install the system in full accordance with the instruction manual. Incorrect installation may cause bursts, personal injury, water leaks, electric shocks and fire. • Be sure to use only for household and residence. If this appliance is installed in inferior environment such as machine shop and etc., it can cause malfunction. • Use the original accessories and the specified components for installation. If parts other than those prescribed by us are used, It may cause water leaks, electric shocks, fire and personal injury. • Install the unit in a location with good support. Unsuitable installation locations can cause the unit to fall and cause material damage and personal injury. • Ensure the unit is stable when installed, so that it can withstand earthquakes and strong winds. Unsuitable installation locations can cause the unit to fall and cause material damage and personal injury. • Ventilate the working area well in the event of refrigerant leakage during installation. If the refrigerant comes into contact with naked flames, poisonous gas is produced. • When installing in small rooms, take prevention measures not to exceed the density limit of refrigerant in the event of leakage. Consult the expert about prevention measures. If the density of refrigerant exceeds the limit in the event of leakage, lack of oxygen can occur, which can cause serious accidents. • After completed installation, check that no refrigerant leaks from the system. If refrigerant leaks into the room and comes into contact with an oven or other hot surface, poisonous gas is produced. • Use the prescribed pipes, flare nuts and tools for R410A. Using existing parts (for R22 or R407C) can cause the unit failure and serious accidents due to burst of the refrigerant circuit. • Tighten the flare nut by torque wrench with specified method. If the flare nut were tightened with excess torque, this may cause burst and refrigerant leakage after a long period. • Do not open the operation valves for liquid line and gas line until completed refrigerant piping work, air tightness test and evacuation. If the compressor is operated in state of opening operation valves before completed connection of refrigerant piping work, air can be sucked into refrigerant circuit, which can cause bust or personal injury due to anomalously high pressure in the refrigerant. • The electrical installation must be carried out by the qualified electrician in accordance with “the norm for electrical work” and “national wiring regulation”, and the system must be connected to the dedicated circuit. Power supply with insufficient capacity and incorrect function done by improper work can cause electric shocks and fire. • Be sure to shut off the power before starting electrical work. Failure to shut off the power can cause electric shocks, unit failure or incorrect function of equipment. • Be sure to use the cables conformed to safety standard and cable ampacity for power distribution work. Unconformable cables can cause electric leak, anomalous heat production or fire. • This appliance must be connected to main power supply by means of a circuit breaker or switch (fuse:16A) with a contact separation of at least 3mm. • When plugging this appliance, a plug conforming to the norm IEC60884-1 must be used. • Use the prescribed cables for electrical connection, tighten the cables securely in terminal block and relieve the cables correctly to prevent overloading the terminal blocks. Loose connections or cable mountings can cause anomalous heat production or fire. • Arrange the wiring in the control box so that it cannot be pushed up further into the box. Install the service panel correctly. Incorrect installation may result in overheating and fire. • Be sure to fix up the service panels. Incorrect fixing can cause electric shocks or fire due to intrusion of dust or water. • Be sure to switch off the power supply in the event of installation, inspection or servicing. If the power supply is not shut off, there is a risk of electric shocks, unit failure or personal injury due to the unexpected start of fan. • Stop the compressor before disconnecting refrigerant pipes in case of pump down operation. If disconnecting refrigerant pipes in state of opening operation valves before compressor stopping, air can be sucked, which can cause burst or personal injury due to anomalously high pressure in the refrigerant circuit • Only use prescribed optional parts. The installation must be carried out by the qualified installer. If you install the system by yourself, it can cause serious trouble such as water leaks, electric shocks, fire. • Do not put the drainage pipe directly into drainage channels where poisonous gases such as sulphide gas can occur.

(2) When the discharge pipe temperature is raised and continues operation for 20 seconds without changing, then the speed is reduced again by 4 rps. (3) If the discharge pipe temperature is still 90ºC or greater but less than 100ºC even when the compressor command speed is maintained for 3 minutes when the temperature is 90ºC or greater but less than 100ºC, the speed is raised by 2 rps and kept at that speed for 3 minutes. This process is repeated until the compressor command speed is reached. (4) Lower limit speed Models 10, 13 Cooling 20 rps Models 18 24 rps b) If the temperature of 110ºC is detected by the sensor on the discharge pipe, then the compressor will stop immediately. When the discharge pipe temperature drops and the time delay of 3 minutes is over, the unit starts again within 1 hour but there is no start at the third time. - 32 - '12 • SRK-T-124 (d) Current safe 1) Purpose: Current is controlled not to exceed the upper limit of the setting operation current. 2) Detail of operation: Input current to the converter is monitored with the current sensor fixed on the printed circuit board of the outdoor unit and, if the operation current value reaches the limiting current value, the compressor command speed is reduced. If the mechanism is actuated when the speed of compressor command is less than 30 rps, the compressor is stopped immediately. Operation starts again after a delay time of 3 minutes. (e) Current cut 1) Purpose: Inverter is protected from overcurrent. 2) Detail of operation: Output current from the converter is monitored with a shunt resistor and, if the current exceeds the setting value, the compressor is stopped immediately. Operation starts again after a delay time of 3 minutes. (f) Outdoor unit failure This is a function for determining when there is trouble with the outdoor unit during air conditioning. The compressor is stopped if any one of the following in item 1), 2) is satisfied. Once the unit is stopped by this function, it is not restarted. 1) When the input current is measured at 1 A or less for 3 continuous minutes or more. 2) If the compressor command sends a 0 rps signal to the indoor unit 3 times or more within 20 minutes of the power being turned on.

(h) Indoor fan motor protection When the air conditioner is operating and the indoor fan motor is turned ON, if the indoor fan motor has operated at 300 rpm or under for more than 30 seconds, the unit enters first in the stop mode and then stops the entire system. (i) Serial signal transmission error protection 1) Purpose: Prevents malfunction resulting from error on the indoor ↔ outdoor signals. 2) Detail of operation a) When the outdoor unit controller cannot receive signals from the indoor unit If the compressor is operating and a serial signal cannot be received from the indoor control with outdoor control having serial signals continuously for 1 minute and 55 seconds, the compressor is stopped. After the compressor has been stopped, it will be restarted after the compressor start delay if a serial signal can be received again from the indoor control. b) When the indoor unit controller cannot receive signals from the outdoor unit i) If the outdoor unit inverter signals cannot be received for 10 seconds continuously during the transfer error check at the first time after turning on the power supply, the compressor is stopped immediately. ii) If the outdoor unit inverter signals cannot be received for 1 minute and 50 seconds continuously, it tries to restart two time but stops the operation at third failure of restart. (j) Rotor lock If the motor for the compressor does not turn after it has been started, it is determined that a compressor lock has occurred and the compressor is stopped. (k) Outdoor fan motor protection If the outdoor fan motor has operated at 75rpm or under for more than 30 seconds, the compressor and fan motor are stopped. - 33 - '12 • SRK-T-124 8. MAINTENANCE DATA (1) Cautions (a) If you are disassembling and checking an air conditioner, be sure to turn off the power before beginning. When working on indoor units, let the unit sit for about 1 minute after turning off the power before you begin work. When working on an outdoor unit, there may be an electrical charge applied to the main circuit (electrolytic condenser), so begin work only after discharging this electrical charge (to DC 10 V or lower). (b) When taking out printed circuit boards, be sure to do so without exerting force on the circuit boards or package components. (c) When disconnecting and connecting connectors, take hold of the connector housing and do not pull on the lead wires. (2) Items to check before troubleshooting (a) Have you thoroughly investigated the details of the trouble which the customer is complaining about? (b) Is the air conditioner running? Is it displaying any self-diagnosis information? (c) Is a power supply with the correct voltage connected? (d) Are the control lines connecting the indoor and outdoor units wired correctly and connected securely? (e) Is the outdoor unit’s service valve open? (3) Troubleshooting procedure (If the air conditioner does not run at all) If the air conditioner does not run at all, diagnose the trouble using the following troubleshooting procedure. If the air conditioner is running but breaks down, proceed to troubleshooting step (4). Important When all the following conditions are met, we say that the air conditioner will not run at all. (a) The RUN light does not light up. (b) The flaps do not open. (c) The indoor unit fan motors do not run. (d) The self-diagnosis display does not function. Troubleshooting procedure (If the air conditioner does not run at all) Is the correct voltage connected for the power supply? NO * If the voltage is correct, it will be within the following voltage range. 198 ~ 264 V Make sure the correct voltage is connected, then perform an operation check. YES With the power off, do the flaps open manually, then close again when the power is turned on? NO Proceed to the indoor PCB check. NO YES Replace the indoor PCB and perform an operation check. YES NO YES Is there a reception sound emitted from the unit when it is operated by the remote controller? Is the current fuse on the indoor unit PCB blown? Proceed to the wireless remote controller troubleshooting procedure. - 34 - If the package components are not damaged, replace the fuse and perform an operation check again. '12 • SRK-T-124 (4) Troubleshooting procedure (If the air conditioner runs) Confirm the contents of the customer complaint. NO The cause of the trouble can be specifically identified. Eliminate the cause of the trouble and perform an operation check. Check the self-diagnosis display. See page 36. Is an error code displayed by the self-diagnosis function? YES NO Using the Service mode, access the self-diagnosis displays generated in the past. See pages 37~40. YES YES Is there a history of selfdiagnosis display items?

If self-diagnosis displays cannot be confirmed, it is possible to get a grasp of the conditions at the time trouble occurred by checking these service data. (a) Explanation of terms Term Explanation Service mode The service mode is the mode where service data are displayed by flashing of the display lights when the operations in item (b) below are performed with the indoor controller. Service data These are the contents of error displays and protective stops which occurred in the past in the air conditioner system. Error display contents and protective stop data from past anomalous operations of the air conditioner system are saved in the indoor unit controller’s non-volatile memory (memory which is not erased when the power goes off). There are two types of data, self-diagnosis data and stop data, described below. Self-diagnosis data These are the data which display the reason why a stop occurred when an error display (selfdiagnosis display) occurred in an indoor unit. Data are recorded for up to previous occurrences. Data which are older than the th previous occurrence are erased. In addition, data on the temperature of each sensor (room temperature, indoor heat exchanger, outdoor heat exchanger, outdoor air temperature, discharge pipe), remote controller information (operation switching, fan speed switching) are recorded when trouble occurs, so more detailed information can be checked. Stop data These are the data which display the reason by a stop occurred when the air conditioning system performed protective stops, etc. in the past. Even if stop data alone are generated, the system restarts automatically. (After executing the stop mode while the display is normal, the system restarts automatically.) Data for up to 0 previous occasions are stored. Data older than the 0th previous occasion are erased. ( Important) In cases where transient stop data only are generated, the air conditioner system may still be normal. However, if the same protective stop occurs frequently ( or more times), it could lead to customer complaints. (b) Service mode display procedure Start Turn off the air conditioner’s power once, then wait 1 minute or longer. Turn the air conditioner’s power on again while pressing the unit ON/OFF button. NO (*) *1:If the buzzer does not sound no matter how many times you repeat the operation, the unit ON/OFF button may be faulty. Did a buzzer located in the indoor unit sound? YES Within 1 minute after turning the air conditioner’s power on, signals will be sent from the remote controller (*2) *2:Set the remote control’s settings on “Cooling operation,” “Fan speed: MED” and “Set temperature: 21ºC.” Count the number of times the RUN light and TIMER light flash (*3), and check the contents of the error, etc. from the table. (See pages 35 and 36.) Are other data displayed? NO YES Change the remote controller settings based on the instructions in the table (*4). (See page 38.) - 37 - Turn off the air conditioner’s power to terminate the service mode. If you are going to turn the power on again, wait 1 minute or longer after turning it off. '12 • SRK-T-124 *3:To count the number of flashes in the service mode, count the number of flashes after the light lights up for 1.5 second initially (start signal). (The time that the light lights up for 1.5 second (start signal) is not counted in the number of flashes.) • In the case of current safe (heating CT1) (example: stop code “32”) The RUN light (10’s digit) flashes 3 times and the TIMER light (1’s digit) flashes 2 times. 3 × 10 + 2 × 1 = 32 → From the table, read the instructions for error code 32, “current safe (heating CT1). 1.5 sec.
