1 GENERAL INFORMATION1.1 Specific featuresThe “MITSUBISHI HEAVY INDUSTRIES, LTD” room air-conditioner: SRK series are of split and wall mounted type and the unitconsists of indoor unit and outdoor unit with refrigerant precharged in factory. The indoor unit is composed of room air cooling orheating equipment with operation control switch and the outdoor unit is composed of condensing unit with compressor.(1) Inverter (Frequency converter) for multi-steps power control¡ Heating/CoolingThe rotational speed of a compressor is changed in step in relation to varying load, interlocked with the indoor and outdoor unitfans controlled to change frequency, thus controlling the capacity.¡Allowing quick heating/cooling operation during start-up period. Constant room temperature by fine-tuned control after the unithas stabilized.(2) Fuzzy control¡ Fuzzy control calculates the amount of variation in the difference between the return air temperature and the setting temperaturein compliance with the fuzzy rules in order to control the air capacity and the inverter frequency.(3) Remote control flap & louverThe flap & louver can be automatically controlled by operating wireless remote control.¡ Flap swing: The flaps swing up and down successively.¡ Louver swing: The louvers swing left and right successively.¡ 3D auto operation : Fan speed and air flow direction are automatically controlled, allowing the entire room to be efficientlyconditioned.¡ Memory flap: Once the flap & louver position is set, the unit memorizes the position and continues to operate at thesame position from the next time.(4) Self diagnosis function¡ We are constantly trying to do better service to our customers by installing such judges that show abnormality of operation asfollows.RUN lightTIMER light1 time flashHeat exchanger sensor 1 error2 time flashTIMER lightON1 time flashCurrent cut2 time flashTrouble of outdoor unit3 time flashOver current4 time flashPower transistor error5 time flashOver heat of compressor6 time flashError of signal transmission7 time flashOutdoor fan motor errorkeep flashingCooling high pressure protectionRUN light2 time flash2 time flashRotor lockRUN light5 time flashONActive filter voltage errorRoom temperature sensor error3 time flashHeat exchanger sensor 3 error6 time flashIndoor fan motor errorRUN lightONTIMER lightRUN lightkeeps flashing1 time flashOutdoor temperature sensor error2 time flashOutdoor heat exchanger liquidpipe sensor error4 time flashDischarge pipe sensor error1.2 How to read the model nameExample :SR K 50 Z HX - SR410A modelsSeries No.Inverter typeProduct capacityWall mounted typeSplit type room air-conditioner-1-

The cabinet can be free standing or wall, pole mount. The single wall type cabinet can be transformed to a double wall type cabinet on site when desired. It may be mounted easily to wall, and has a capacity to bear 450kg load with wall mount devices. The wall type cabinet can be transformed to free standing type by adding plinth only on site.
