Safety CautionsFor general public usePower supply cord of parts of appliance for Outdoor use shall be at least polychloroprene sheathed flexiblecord (design H07 RN-F), or cord designation 245 IEC66.CAUTIONNew Refrigerant Air conditioner Installation• THIS AIR CONDITIONER USES THE NEW HFC REFRGERANT (R410A), WHICH DOES NOT DESTROYTHE OZONE LAYER.R410A refrigerant is apt to be affected by impurity such as water, oxidizing membranes, and oils because thepressure of R410A refrigerant is approx. 1.6 times of refrigerant R22. As well as the adoption of this newrefrigerant, refrigerating machine oil has also been changed. Therefore, during installation work, be sure thatwater, dust, former refrigerant, or refrigerating machine oil does not enter into the refrigerating cycle of anew-refrigerant air conditioner.To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections onthe main unit are different from those for the conventional refrigerant, and different size tools are alsorequired. Accordingly, special tools are required for the new refrigerant (R410A) as shown below. Forconnecting pipes, use new and clean piping materials with high-pressure withstand capabilities, designed forR410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping as itspressure withstand may be insufficient, and may contain impurities.CAUTIONTo Disconnect the Appliance from the Main Power SupplyThis appliance must be connected to the main power supply by means of a circuit breaker or a switch with acontact separation of at least 3 mm.If this is not possible, a power supply plug with earth must be used. This plug must be easily accessible afterinstallation. The plug must be disconnected from the power supply socket in order to disconnect theappliance completely from the mains.− 37 −

Incorrect cable connection between Indoorand outdoor unitsThe indoor unit is connected to the outdoor unit with5 cables (Heat pump model) or 3 cables (Cooling Onlymodel). Check that the indoor and outdoor units havebeen properly connected with terminals assigned thesame numbers. If the connectors are not properlyconnected, the outdoor unit will not operate normally,or OPERATION lamp and TIMER lamp will blink (5Hz).9-2-3. Program controlThe microcontroller operates as shown in Table 9-2-1to control the air conditioner. If there are any operationalproblems, check whether or not the problemscorrespond to Table 9-2-1. If they correspond to theTable, they are not problems with the air conditioner,but they are indispensable operations to control andmaintain the air conditioner properly.1 When the main power supply is turned on,the OPERATION lamp on the indoor unitblinks.2 The indoor fan motor speed does not changein the Dry operation.3 The compressor is not turned off even thoughthe room temperature is in the range that thecompressor is turned off.4 The compressor is not turned on and off eventhough the thermo control is operated in theDry operation.5 The PRE-DEF. lamp is indicated when theHeating operation starts.6 The outdoor fan motor stops in the Heatingoperation.7 The compressor is not turned on even thoughthe room temperature is in the range that thecompressor is turned on.8 The operation mode changes in theAutomatic operation.9 The Fan only operation continues in theAutomatic operation.10 The Hi-POWER operation does not work.Table 9-2-1No. Operation of air conditioner DescriptionsThe OPERATION lamp blinks to indicate that power is turned on.If the [ ] button is pressed, the lamp stops blinking.The indoor fan motor speed is automatically controlled in the Dryoperation.The compressor has a function that it is not turned off for3 minutes after it is turned on even though the room temperatureis in the range that the compressor is turned off.In the Dry operation, the compressor is turned on and offautomatically at the regular intervals, independent of the thermocontrol.The PRE-DEF. lamp is indicated during the Defrostingoperation or if the indoor heat exchanger temperature is low whenthe Heating operation starts. At this time, the indoor fan motorstops to prevent cold air from blowing in the room.When the indoor heat exchanger temperature is high, the outdoorfan motor is stopped by the high-temperature limit controloperation.The compressor is not turned on in the restart delay timer(3-minutes timer) operation. It is also not turned on after the powersupply is turned on because of this timer operation.In Automatic operation, the room temperature is detected all timefor control fan speed and the operation mode is changed every15 minutes according to difference between the room temperatureand the preset temperature.When the room temperature is in the range (Preset temperature± 1°C), the Fan only operation is selected.This operation does not work when the unit is in the Dry operationor Fan only operation.− 53 −
