• Do not install the air conditioner at any place where flammable gas may leak out. If the gas leaks out and stays around the air conditioner, a fire may break out. • Operating the air conditioner with wet hands could result in a shock hazard. • Check the unit stand for damage on a continuous basis. If left in a damaged condition the unit may fall and cause injury. • Do not allow children to play on or around the unit as they could be injured.
• Arrange the drain pipe to ensure smooth drainage. Incomplete drainage may cause wetting of the building, furniture etc. • Do not place the controller exposed to direct sunlight. The LCD display may get discolored, failing to display the data. • Do not wipe the controller operation panel with benzine, thinner, chemical dustcloth, etc. The panel may get discolored or the coating peeled off. If it is heavily dirty, soak a cloth in water-diluted neutral detergent, squeeze it well and wipe the panel clean.
Regarding drainage of drain pipe • Is the drain pipe executed to perform complete drainage? If proper drainage is not carried out from the outdoor drain pipes during air-conditioning operation, chances are that dust and dirt are clogged in the pipe. This may result in a water leakage from the indoor unit. Under such circumstances, stop the operation of the air conditioner, and then consult your dealer or our service station. 5.

• A “Shuh” sound which is heard at the start or immediately after the stop of operation or which is heard at the start or immediately after the stop of DEFROST OPERATION. This is the noise of refrigerant caused by flow stop and flow change. • A “Pishi-pishi” squeaking sound is heard when the system is in operation or after the stop of operation. Expansion and contraction of plastic parts caused by temperature change makes this noise. V.
3. The system operates but it does not sufficiently cool or heat. • If the air inlet or outlet of the indoor or the outdoor unit is blocked with obstacles. Remove the obstacle and make it well-ventilated. • If the air filter is clogged. Ask a qualified service person to clean the air filters. (Refer to “MAINTENANCE”) • If the set temperature is not proper. (Refer to “ADJUSTMENT”) • If the FAN SPEED button is set to LOW SPEED.
