SAFETY PRECAUTION Please read the “Safety Precaution” carefully before operating the unit to ensure correct usage of the unit.Pay special attention to signs of “ ! Warning” and “ ! Caution”. The “Warning” section contains matters which,if not observed strictly, may cause death or serious injury. The “Caution” section contains matters which mayresult in serious consequences if not observed properly. Please observe all instructions strictly to ensure safety.The sign indicate the following meanings.The sign in the figure indicates prohibition.Make sure to connect earth line.Indicates the instructions that must be followed. Please keep this manual after reading.PRECAUTIONS DURING INSTALLATION! Do not reconstruct the unit.Water leakage, fault, short circuit or fire may occur if you reconstructthe unit by yourself. Please ask your sales agent or qualified technician for the installationof your unit. Water leakage, short circuit or fire may occur if you installthe unit by yourself. Please use earth line.Do not place the earth line near water or gas pipes, lightning-conductor,or the earth line of telephone. Improper installation of earth line maycause electric shock. A circuit breaker should be installed depending on the mounting site ofthe unit. Without a circuit breaker, the danger of electric shock exists. Do not install the unit near a location where there is flammable gas.The outdoor unit may catch fire if flammable gas leaks around it. Please ensure smooth flow of water when installing the drain hose.WARNING!CAUTIONPRECAUTIONS DURING SHIFTING OR MAINTENANCE!WARNING Should abnormal situation arises (like burning smell), please stop operating the unitand turn off the circuit breaker. Contact your agent. Fault, short circuit or fire mayoccur if you continue to operate the unit under abnormal situation. Please contact your agent for maintenance. Improper self maintenance may causeelectric shock and fire. Please contact your agent if you need to remove and reinstall the unit. Electricshock or fire may occur if you remove and reinstall the unit yourself improperly.PRECAUTIONS DURING OPERATION!WARNING Avoid an extended period of direct air flow for your health. Do not insert a finger, a rod or other objects into the air outlet or inlet. As thefan is rotating at a high speed, it will cause injury. Before cleaning, be sureto stop the operation and turn the breaker OFF.Do not use any conductor as fuse wire, this could cause fatal accident. During thunder storm, disconnect and turn off the circuit breaker.– 2 –RAS/RAC-260/350GHA (EN1)218/1/06, 10:21 AM
PRECAUTIONS DURING OPERATION The product shall be operated under the manufacturer specification andnot for any other intended use. When operating the unit with burning equipments, regularly ventilate theroom to avoid oxygen insufficiency. CAUTIONPlease switch off the unit and turn off the circuit breaker during cleaning, thehigh-speed fan inside the unit may cause danger.Turn off the circuit breaker if the unit is not to be operated for a long period. Do not splash or direct water to the body of the unit when cleaning it as thismay cause short circuit.Do not use any aerosol or hair sprays near the indoor unit. This chemicalcan adhere on heat exchanger fin and blocked the evaporation water flowto drain pan. The water will drop on tangential fan and cause water splashingout from indoor unit. Do not direct the cool air coming out from the air-conditioner panel to facehousehold heating apparatus as this may affect the working of apparatussuch as the electric kettle, oven etc.Please ensure that outdoor mounting frame is always stable, firm andwithout defect. If not, the outdoor unit may collapse and cause danger. !Do not attempt to operate the unit with wet hands, this could cause fatalaccident.Do not climb on the outdoor unit or put objects on it.Do not put water container (like vase) on the indoor unit to avoid waterdripping into the unit. Dripping water will damage the insulator inside the unitand causes short-circuit. Do not place plants directly under the air flow as it is bad for the plants.When operating the unit with the door and windows opened, (the room humidity is always above80%) and with the air deflector facing down or moving automatically for a long period of time,water will condense on the air deflector and drips down occasionally. This will wet your furniture.Therefore, do not operate under such condition for a long time. If the amount of heat in the room is above the cooling or heating capability of the unit (forexample: more people entering the room, using heating equipments and etc.), the preset roomtemperature cannot be achieved. – 3 –RAS/RAC-260/350GHA (EN1)318/1/06, 10:21 AM
