SiBE12-713 Introduction 1. Introduction 1.1 Safety Cautions Cautions and Warnings Be sure to read the following safety cautions before conducting repair work. 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. The “ Caution” items can also lead to serious accidents under some conditions if they are not followed.
Introduction SiBE12-713 Warning Be sure to wear a safety helmet, gloves, and a safety belt when working at a high place (more than 2m). Insufficient safety measures may cause a fall accident. In case of R410A refrigerant models, be sure to use pipes, flare nuts and tools for the exclusive use of the R410A refrigerant. The use of materials for R22 refrigerant models may cause a serious accident such as a damage of refrigerant cycle as well as an equipment failure.
SiBE12-713 Introduction 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. If the power cable and lead wires have scratches or deteriorated, be sure to replace them.
Introduction SiBE12-713 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. only Incorrect use of the installation frame and improper installation may cause the equipment to fall, resulting in injury.
SiBE12-713 Introduction 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. Do not tilt the unit when removing it. The water inside the unit may spill and wet the furniture and floor.

Main Functions SiBE12-713 1. Main Functions Note: 1.1 See the list of functions for the functions applicable to different models. Frequency Principle Main Control Parameters The compressor is frequency-controlled during normal operation.
SiBE12-713 Inverter Features Main Functions The inverter provides the following features: The regulating capacity can be changed according to the changes in the outdoor air temperature and cooling / heating load. Quick heating and quick cooling The compressor rotational speed is increased when starting the heating (or cooling). This enables a quick set temperature.
Main Functions 1.2 SiBE12-713 Power-Airflow Dual Flaps, Wide Angle Louvers and Auto-Swing Power-airflow Dual Flaps The large flaps send a large volume of air downwards to the floor. The flap provides an optimum control area in cooling, heating and dry mode. Heating Mode During heating mode, the large flap enables direct warm air straight downwards. The flap presses the warm air above the floor to reach the entire room. Cooling Mode During cooling mode, the flap retracts into the indoor unit.
SiBE12-713 Main Functions FTK(X)S20-50D The vertical swing flap is controlled not to blow the air directly on the person in the room. The airflow rate is controlled automatically within the following steps. Cooling: L tap – MH tap (same as AUTOMATIC) Heating: ML tap – M tap The latest command has the priority between POWERFUL and COMFORT AIRFLOW.
Main Functions 1.3 SiBE12-713 Operation Starting Control FTXG25-35E, CTXG50E The system carries out the following control at the beginning to conduct every functional parts properly. 1.
