Page 4 Introduction SiK011002 1. Introduction Safety Cautions Cautions and Be sure to read the following safety cautions before conducting repair work. Warnings The caution items are classified into “ Warning” and “ Caution”. The “ Warning” items are especially important since they can lead to death or serious injury if they are not followed closely.
Page 5 SiK011002 Introduction Warning Be sure to wear a safety helmet, gloves, and a safety belt when working at a high place (more than 2 m). Insufficient safety measures may cause a fall accident. In case of R-410A refrigerant models, be sure to use pipes, flare nuts and tools for the exclusive use of the R-410A refrigerant.
Page 6 Introduction SiK011002 1.1.2 Cautions Regarding Safety of Users Warning Be sure to use parts listed in the service parts list of the applicable model and appropriate tools to conduct repair work. Never attempt to modify the equipment. The use of inappropriate parts or tools may cause an electrical shock, excessive heat generation or fire.
Page 7 SiK011002 Introduction Warning Check to make sure that the power cable plug is not dirty or loose, then insert the plug into a power outlet securely. If the plug has dust or loose connection, it may cause an electrical shock or fire. Be sure to install the product correctly by using the provided standard For unitary type installation frame.
Page 8 Introduction SiK011002 Caution Be sure to measure the insulation resistance after the repair, and make sure that the resistance is 1 MΩ or higher. Faulty insulation may cause an electrical shock. Be sure to check the drainage of the indoor unit after the repair. Faulty drainage may cause the water to enter the room and wet the furniture and floor.

Page 29 SiK011002 Function and Control 1. Function and Control Note: Basic functions (the centigrade is used in the following function manual. If there will be Fahrenheit degree, that will be Tf = Tc × 1.8 + 32). Temperature Parameters Indoor preset temperature (Tpreset) Indoor ambient temperature (Tamb.) Basic Functions Once energized, the compressor shall never be restarted except 3-min interval at least.
Page 30 Function and Control SiK011002 Overcurrent Protection (Applicable to some models) If it is detected that the system amperage exceeds the specified value in 3 s successively, the outdoor unit will enter into the state that only the fan is running. If the overcurrent protection is released, the complete unit will resume its previous running state.
Page 31 SiK011002 Function and Control 1.1.3 Heating Mode (Cooling only unit is not available) Heating Conditions and Process When Tamb. ≤ Tpreset + 2 °C, the unit will run in heating mode. In this case, the four-way valve, the compressor and the outdoor fan will run simultaneously. The indoor fan will delay at most 2 mins to run.
Page 32 Function and Control SiK011002 Other Control 1.2.1 Timer Function The mainboard combines general timer and clock timer functions. Timer functions are selected by equipping remote controller with different functions. General Timer Timer ON can be set under off state of unit. If timer ON reaches, the controller will run under previous setting mode.
Page 33 SiK011002 Function and Control 1.2.8 Up & Down Swing After energization, up & Down swing motor will rotate guide louver anticlockwise to position 0 to close air outlet. After turning on the unit, if swing function has not been set, up & down guide louver will clockwise turn to position D in heating mode, or clockwise turn to level position L in other modes.
Page 34 Function and Control SiK011002 1.2.11 Power-Off Memory Memory content includes mode, up & down swing, light, setting temp and setting fan speed. Upon power failure, the unit after power recovery will automatically start to run according to memory content. The system, last remote-control command without timer setting, will memorize the last remote-control signal and run according to it.
