Cautions on troubleshooting 1-1. Before troubleshooting, check the following: 1) Check the power supply voltage. 2) Check if the indoor/outdoor connecting wire is correct. 1-2. Take care the following during servicing. 1) Before servicing the air conditioner, be sure to turn OFF the main unit first with the remote controller, and turn off the breaker. 2) Be sure to turn OFF the power supply before removing the front panel, the cabinet, the top panel, and the electronic control P.C. board. 3) When removing the electrical parts, be careful to the residual voltage of smoothing capacitor. 4) When removing the electronic control P.C. board, hold the edge of the board with care NOT to apply stress on the components. 5) When connecting or disconnecting the connectors, hold the housing of the connector. DO NOT pull the lead wires. Lead wire Housing point TROUBLESHOOTING 1) First, check if the OPERATION INDICATOR lamp is blinking on and off to indicate an abnormality. To make sure, check how many times the abnormality indication is blinking on and off before starting service work. 2) Before servicing, check that the connector and terminal are connected properly. 3) If the electronic control P.C. board is supposed to be defective, check the copper foil pattern for disconnection and the components for bursting and discoloration. 4) When troubleshooting, refer to “2.Failure model recall function”.

Take care not to discharge refrigerant into the atmosphere during installation, reinstallation, or repairs to the refrigerant circuit. • For additional charging, charge the refrigerant from liquid phase of the gas cylinder. If the refrigerant is charged from the gas phase, composition change may occur in the refrigerant inside the cylinder and the outdoor unit. In this case, ability of the refrigerant cycle decreases and normal operation can become impossible. However, charging the liquid refrigerant all at once may cause the compressor to be locked. Thus, charge the refrigerant slowly. To maintain the high pressure of the gas cylinder, warm the gas cylinder with warm water (under 40) during cold season. But never use naked fire or steam.

How to measure the indoor air wet-bulb/dry-bulb temperature difference 1. Attach at least 2 sets of wet-and-dry-bulb thermometers to the indoor air inlet as shown in the figure, and at least 2 sets of wet-and-dry-bulb thermometers to the indoor air outlet. The thermometers must be attached to the position where air speed is high. 2. Attach at least 2 sets of wet-and-dry-bulb thermometers to the outdoor air inlet. Cover the thermometers to prevent direct rays of the sun. 3. Check that the air filter is cleaned. 4. Open windows and doors of the room. 5. Press the EMERGENCY OPERATION switch once to start the COOL (HEAT) MODE. 6. When system stabilizes after more than 15 minutes, measure temperature and take an average temperature. 7. 10 minutes later, measure temperature again and check that the temperature does not change.

Failure mode recall function Outline of the function This air conditioner can memorize the abnormal condition which has occurred once. Even though OPERATION INDICATOR lamp indication listed on the troubleshooting check table disappears, the memorized failure details can be recalled. This mode is very useful when the unit needs to be repaired for the abnormality which does not recur. 1. Flow chart of failure mode recall function for the indoor/outdoor unit Operational procedure The cause of abnormality cannot be found because the abnormality does not recur. While pressing both OPERATION SELECT button and TOO COOL button on the remote controller at the same time, press RESET button. First, release RESET button. And release the other two buttons after all LCD except the set temperature in operation display section of the remote controller is displayed after 3 seconds. Setting up the failure mode recall function Turn ON the power supply. While pressing both OPERATION SELECT button and TOO COOL button on the remote controller at the same time, press RESET button. First, release RESET button. And release the other two buttons after all LCD except the set temperature in operation display section of the remote controller is displayed after 3 seconds. 1. Regardless of normal or abnormal, a short beep is emitted once as the signal is received. Press OPERATE/STOP(ON/OFF) button of the remote controller (the set temperature is displayed) with the remote controller headed towards the indoor unit. 1 Does the left lamp of OPERATION INDICATOR lamp on the indoor unit blink at the interval of 0.5 seconds? Blinks: Either indoor or outdoor unit is abnormal. Beep are emitted at the same timing as the blinking of the left lamp of OPERATION INDICATOR lamp. 2 Yes (Blinks) Judgment of indoor/outdoor abnormality No (OFF) Before blinking, does the left lamp of OPERATION INDICATOR lamp stay ON for 3 seconds? Stays ON for 3 seconds (without beep): The outdoor unit is abnormal. Indoor unit is normal. But the outdoor unit might be abnormal because there are some abnormalities that are not memorized in the indoor unit. Confirm if outdoor unit is abnormal according to the flow chart of the detailed outdoor unit failure mode recall function. Yes The indoor unit is abnormal. Check the blinking pattern, and confirm the abnormal point with the indoor unit failure mode table. Make sure to check at least two consecutive blinking cycles. The outdoor unit is abnormal. Check the blinking pattern, and confirm the abnormal point. Make sure to check at least two consecutive blinking cycles. FLOORSTANDING TROUBLESHOOTING No 3 2 Releasing the failure mode recall function Release the failure mode recall function by the following procedures. Turn OFF the power supply and turn it ON again. Press RESET button of the remote controller. As for outdoor unit, refer to outdoor unit service manual. Repair the defective parts. Deleting the abnormal memorized condition After repairing the unit, recall the failure mode again according to "Setting up the failure mode recall function" mentioned above. Press OPERATE/STOP(ON/OFF) button of the remote controller (the set temperature is displayed) with the remote controller headed towards the indoor unit. 1 Press EMERGENCY OPERATION switch so that the memorized abnormal condition is deleted. Release the failure mode recall function according to "Releasing the failure mode recall function" mentioned above. Note1.Make sure to release the failure mode recall function once it is set up, otherwise the unit cannot operate properly. 2.If the abnormal condition is not deleted from the memory, the last abnormal condition is kept memorized. 2.
