CAUTIONS Disposal of the old air conditioner Before disposing an old air conditioner that goes out of use, please make sure it's inoperative and safe. Unplug the air conditioner in order to avoid the risk of child entrapment. It must be noticed that air conditioner system contains refrigerants, which require specialized waste disposal. The valuable materials contained in a air conditioner can be recycled.
SAFETY PRECAUTIONS Before starting to use the system, read carefully this"SAFETY PRECAUTIONS" to ensure a proper operation of the system. Safety precautions described here are classified to " WARNING" and " CAUTION". Precautions which are shown in the column of " WANING" means that an improper handing could lead to a grave result like a death, serious injury, etc. However, even if precautions are shown in the column of " CAUTION", a very serious problem could occur depending on situation.
SAFETY PRECAUTIONS CAUTION Do not wash the air conditioner with water. It could cause electric shocks. Neither stand on the air conditioner nor place something on it. Do not install the system where the air outlet reaches directly the flora and fauna. Make sure to use a fuse of proper electric rating. It will not be good for their health. Use of steel or copper wire in place of a fuse is strictly prohibited because it could result in a trouble or fire accident.
SAFETY PRECAUTIONS The machine is adaptive in following situation 1. Applicable ambient temperature range: Indoor Maximum:D.B / W.B 32 C/ 23 C Minimum: D.B / W. 18 C/ 14 C Outdoor Maximum: D.B Minimum: D.B 43 C/ 26 C 15 C Indoor Maximum: D.B Minimum: D.B 27 C 20 C Outdoor Maximum: D.B / W.B 24 C/ 18 C Minimum: D.B / W.B -7 C/ -8 C Cooling Heating 2. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similar qualified person.

MALFUNCTION please check the following things about your air conditioner before making a servie call. Unit fails to start Is city supply power in normal? Is the power source switch adjust cut in? Isn't the signal receiving Isn't the earth leakage section exposed to the breaker in action? direct sunlight or strong illumination? It is dangerous. Turn off the power supply switch immediately and contact the sales dealer. ON Power stoppage? OFF Power supply switch is not ON.
MALFUNCTION The followings are not malfunction Water flowing sound is heard. Sh Sh uru ur u When the air conditioner is started, when the compressor starts or stops during operation or when the air conditioner is stopped, it sometimes sounds "shuru shuru" or "gobo gobo". It is the flowing sound of the refrigerant, and it is not a trouble. Cracking sound is heard. This is caused by heat expansion or contraction of plastics. It smells. Air which blows out from the indoor unit sometimes smells.
CARE AND MAINTENANCE Points to observe Turn off the power supply switch. Do not touch with wet hand. Do not use hot water or volatileliquid. ON Thinner Do not use! Benzine Tooth powder OFF CAUTION Do not open the inlet grill until fan stops completely. Fan will continue rotating for a while by the law of inertia after operation is being stopped. Cleaning 1. Clean the air filter by lightly tapping it or with the cleaner. It is more effective to clean the air filter with water.
CARE AND MAINTENANCE "HOT KEEP"is operated in the following cases. When heating is started: In order to prevent blowing out of cool wind, the indoor unit fan stopped according to the room temperature which heating operation is started. Wait for approx. 2 to 3 minute, and the operation will be automatically changed to the ordinary heating mode. Defrosting operation (in the heating mode): When it is liable to frost. the heating operation is stopped automatically for 5 to 12 minutes once per approx.
