If the air filter is blocked, the cooling and heating performance may decrease. Remove dirt regularly. • Check if the outdoor unit is covered or installed near the obstacle. Take the cover off and take the obstacle away. When clearing the obstacle (e.g. snow or ice), use suitable tools so as to be careful not to damage the product nor injure yourself during this process. • Check whether the air conditioner is running the defrost function. When ice forms in winter or the outdoor temperature is too low, the air conditioner runs the defrost function automatically. While this function is running, the indoor fan stops and warm air does not come out. • Check whether doors or windows are open. This may cause poor cooling or heating performance. Close the doors and windows. • Check whether the air conditioner is turned on immediately after the cooling or heating operation stops. In this case, only the fan runs to protect the outdoor unit compressor. • Check whether the pipe length is too long. When the pipe length exceeds the maximum pipe length, the cooling and heating performance may decrease. Troubleshooting Problem Solution I cannot change the air flow direction. • Check whether the good'sleep function is running. While this function is running, you cannot control the air flow direction. (But you can control the air flow direction if this function is running in the Heat mode.) I cannot change the fan speed. • When the Auto, Dry, or Fast mode is running or the good'sleep function is running in the Cool mode, the air conditioner controls the fan speed automatically and you cannot change the fan speed. The remote control does not work. • Replace the batteries in the remote control with new ones. • Make sure that nothing is blocking the remote control sensor. • Check whether there are strong lighting apparatus near the air conditioner. Strong light which comes from fluorescent bulbs or neon signs may interrupt the electric waves. The Timed on/off function does not work. • Check whether you pressed the SET button on the remote control after setting the time. The indicator blinks continuously. • Press the Power button to turn off the air conditioner or disconnect the power plug. If the indicator is still blinking, contact the service centre. Appendix 34 English Problem Solution Odours permeate in the room during operation. • Check whether the air conditioner is running in a smoky area. Ventilate the room or operate the air conditioner in the Fan mode for 3 to 4 hours. (There are no components used in the air conditioner that emit a strong odour.) • Check whether the drains are clean. Clean them regularly. An error is indicated. • If the indoor unit indicator blinks, contact the nearest service centre. Be sure to pass the error code to the service centre. Noise is generated. • When refrigerant flow changes, noise may be generated, depending on the status of the air conditioner. This is a normal operation. 'Excessive Noise is Generated' and ‘Reduced Performance' • If excessive/irregular noise is generated in conjunction with reduced product performance, please refer to your service engineer to ensure the product is operating correctly. Smoke is generated from the outdoor unit. • If may not be a fire but it can be a steam generated from the outdoor heat exchanger while the defrost function is running in the Heat mode in winter. Water drops from the pipe connections of the outdoor unit. • Condensation may develop when the ambient temperature changes excessively. This is a normal operation. Appendix English 35 Operation Ranges The table below indicates the temperature and humidity ranges the air conditioner can be operated within. Refer to the table for efficient use. MODE OPERATIONAL TEMPERATURE INDOOR HUMIDITY INDOOR OUTDOOR COOLING 16 ˚C to 32 ˚C -5 ˚C to 48 ˚C 80 % or less HEATING 27 ˚C or less -20 ˚C to 24 ˚C - DRYING 16 ˚C to 32 ˚C -5 ˚C to 48 ˚C - NOTE • The standardized temperature for heating is 7 ˚C. If the outdoor temperature drops to 0 ˚C or below, the heating capacity can be reduced depending on the temperature condition. • If the cooling operation is used at over 32˚C (indoor temperature), it does not cool at its full capacity.
