5The refrigerant in the air conditioner is safe and nor-mally does not leak. If the refrigerant leaks inside theroom, the contact with a fire of a burner, a heater or acooker may result in a harmful gas.Do not use the air conditioner until when a service personconfirms to finish repairing the portion where the refriger-ant leaks.Do not use any fuse with improper capacity.The use of a piece of wire and whatnot may result in a fail-ure and fire.Be sure to establish an earth.Do not earth the unit to a utility pipe, arrester, or tele-phone earth.Incomplete earth may cause electrical shock, or fire.A high surge current from lightning or other sources maycause damage to the air conditioner.Be sure to install an earth leakage breaker.Failure to install an earth leakage breaker may result inelectric shocks, or fire.CAUTIONDo not use the air conditioner for other purposes.Do not use the air conditioner for a special application suchas the storage of foods, animals and plants, precisionmachines, and art objects as otherwise the deterioration ofquality may result.Do not remove the air outlet of the outdoor unit.The fan may get exposed and result in injury.When the air conditioner is used in combination withburners or heaters, perform sufficient ventilation.Insufficient ventilation may result in an oxygen deficiencyaccident.Check and make sure that foundation blocks are notdamaged after a long use.If they are left in a damaged condition, the unit may fall andresult in injury.Neither place a flammable spray bottle near the airconditioner nor perform spraying.Doing so may result in a fire.To clean the air conditioner, stop operation, andunplug the power cord from the outlet.Otherwise, an electric shock and injury may result.Do not operate the air conditioner with a wet hand.An electric shock may result.Do not place items which might be damaged bymoisture under the indoor unit which may be dam-aged by water.Condensation may form if the humidity is above 80%, if thedrain outlet gets blocked or the filter is polluted.Do not place a burner or heater at a place directlyexposed to the wind from the air conditioner.Incomplete combustion of the burner or heater may result.Do not allow a child to mount on the outdoor unit oravoid placing any object on it.Falling or tumbling may result in injury.Do not expose animals and plants directly to thewind.Adverse influence to animals and plants may result.Do not wash the air conditioner with water.Electric shock or fire may result.Do not install the air conditioner at any place whereflammable gas may leak out.If the gas leaks out and stays around the air conditioner, afire may break out.Execute complete drain piping for perfect drainage.Incomplete piping may result in a water leakage.The appliance is not intended for use by young chil-dren or infirm persons without supervision.Young children should be supervised to ensure thatthey do not play with the appliance.Consult with installation contractor for cleaning theinside of the air conditioner.Wrong cleaning may make the plastics parts broken orcause failure of water leakage or electric shock.Do not touch the air inlet or aluminium fin of the airconditioner.Otherwise, injury may be caused.Do not place objects in direct proximity of the out-door unit and do not let leaves and other debrisaccumulate around the unit.Leaves are a hotbed for small animals which can enter theunit. Once in the unit, such animals can cause malfunc-tions, smoke or fire when making contact with electricalparts.OPERATION RANGEIf the temperature or the humidity is beyond the following con-ditions, safety devices may work and the air conditioner maynot operate, or sometimes, water may drop from the indoorunit.CoolingHeating**–20~–15°CWB: Range for operation–15~15.5°CWB: Range for continuous operationDB: Dry bulb temperature WB: Wet bulb temperatureThe setting temperature range of the remote controller is16°C to 32°C. Tips for saving energy• Be careful not to cool (heat) the room too much.Keeping the temperature setting at a moderate levelhelps save energy.• Cover windows with a blind or a curtain.Blocking sunlight and air from outdoors increases thecooling (heating) effect.INDOOR OUTDOORTEMPERATURETEMPERATURE HUMIDITYDB 21 to 32 °C 80% or below(Long time operation in ahumidity over 80% maycause condensation onthe unit and dripping.)DB –5 to 46 °CWB 14 to 25 °CINDOORTEMPERATUREOUTDOORTEMPERATUREDB 15 to 27 °CDB –20 to 21 °C**WB –20 to 15.5 °C**Recommended temperature settingFor cooling 26 to 28 °CFor heating 20 to 24 °C
