SiBE12-816_D 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 SiBE12-816_D 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. The use of materials for R-22 refrigerant models may cause a serious accident such as a damage of refrigerant cycle as well as an equipment failure.
SiBE12-816_D 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 SiBE12-816_D 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 only installation frame. Incorrect use of the installation frame and improper installation may cause the equipment to fall, resulting in injury.
SiBE12-816_D 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.

SiBE12-816_D 1.4 Function of Indoor Unit (RA Models) Airflow Direction Control Power-Airflow Dual Flaps The large flaps send a large volume of air downwards to the floor. The flap provides an optimum control in cooling, dry, and heating mode. Cooling / Dry Mode During cooling or dry mode, the flap retracts into the indoor unit. Then, cool air can be blown far and pervaded all over the room.
Function of Indoor Unit (RA Models) SiBE12-816_D Floor / Ceiling Suspended Dual Type Vertical Swing (up and down) Cooling / Dry / Fan Heating 65˚ 20˚ 40˚ Ceiling 95 ˚ (R2964) (R2963) 95 ˚ 40˚ 20˚ Floor (R2966) (R2967) 3-D Airflow ˚ 65 Wall Mounted Type: FTXS Series Alternative repetition of vertical and horizontal swing motions enables uniform air-conditioning of the entire room. This function is effective for starting the air conditioner.
SiBE12-816_D 1.5 Function of Indoor Unit (RA Models) Fan Speed Control for Indoor Units Outline Phase control and fan speed control contains 9 steps: LLL, LL, SL, L, ML, M, MH, H, and HH. The airflow rate can be automatically controlled depending on the difference between the room thermistor temperature and the target temperature. This is done through phase control and Hall IC control. For more information about Hall IC, refer to the troubleshooting for fan motor on page 218, 219.
Function of Indoor Unit (RA Models) COMFORT AIRFLOW Operation 1.6 SiBE12-816_D Wall Mounted Type The fan speed is controlled automatically within the following steps. Cooling: L tap – MH tap (same as AUTOMATIC) Heating: ML tap – M tap ~ MH tap (depending on the model) The latest command has the priority between POWERFUL and COMFORT AIRFLOW. Program Dry Operation Outline Program dry operation removes humidity while preventing the room temperature from lowering.
SiBE12-816_D 1.7 Function of Indoor Unit (RA Models) Automatic Operation Outline Detail Automatic Cooling / Heating Function When the AUTO mode is selected with the remote controller, the microcomputer automatically determines the operation mode as cooling or heating according to the room temperature and the set temperature at start-up, and automatically operates in that mode. The unit automatically switches the operation mode to maintain the room temperature at the set temperature.
Function of Indoor Unit (RA Models) 1.8 SiBE12-816_D Thermostat Control Thermostat control is based on the difference between the room thermistor temperature and the target temperature. Thermostat OFF Condition The temperature difference is in the zone A. Thermostat ON Condition The temperature difference returns to the zone C after being in the zone A. The system resumes from defrost control in any zones except A. The operation turns on in any zones except A.
SiBE12-816_D Function of Indoor Unit (RA Models) Heating Wall Mounted Type: FTXG-J, CTXG-J Series Room thermistor temperature – target temperature OFF A 2.0˚C B 1.5˚C C 0.5˚C ON (R11894) Wall Mounted Type: FTXG-E, CTXG-E, FTXS Series Floor Standing Type Room thermistor temperature – target temperature OFF A 1.5˚C B 1.0˚C C 0˚C ON (R12320) Floor / Ceiling Suspended Dual Type Duct Connected Type Room thermistor temperature – target temperature OFF A 1.5˚C B 1.0˚C C 0.
