3. Disassembly and reassembly 3-1 Indoor unit Parts Procedure Remark Indoor unit Inlet grille 1) Open the inlet grille and remove the connection ring. Main PCB 1) Separate the PCB connect wire after separating the control box cover. 2) Separate the connection wire to separate the front cover and duct.
Page 8 Parts Procedure Remark Front cabi 1) The front cabi should be separated by giving strength downward after loosening 2 screws at the lower end. Plate top 1) The plate top should be separated by loosening screws.
Page 9 Parts Procedure Remark Ass’y grille out 1) First loosen screws at left and right sides of grille out. 2) Then the ass’y grille out should be separated by giving strength upward (↑). & Ass’y duct 1) First loosen the 4 screws at left and right sides. 2) Then the ass’y duct should be separated by lifting it.
Page 10 Parts Procedure Remark Evaporator 1) First separate the cover after loosening the screws fixed at evap cover R. 2) Ten separate the 3 screws fixed at cabinet BKT of evaporator BKT. 3) Evaporator should be separated by flinging ahead.
Page 11 Parts Procedure Remark Motor 1) When the ass’y duct should be separated from the motor, the 2 bracket should be separated first. 2) Then the bolts fixed at the blower and motor shaft should be separated. 3) Then the screws binding the holder top blower and duct should be separated.
Page 12 Parts Procedure Remark 6) Then the motor should be separated. 7) The bracket fixed at the motor should be separated. Panel PCB 1) Should be separated after loosening the insulating material and binders at the back of the front side.
Page 13 3-2 Outdoor Unit Parts Procedure Remark Outdoor unit 1) Packaged air conditioner outdoor unit 2) The binders of the front side should be separated. 3) The flank and the binders should be separated from each other. Control box 1) Connect distributed wires in the control box.

4. Troubleshooting Troubleshooting First, Items to be checked first Second, Check the corrective actions in the case of occurrence of self-diagnosis mode Third, When the trouble is not related to the 1st or 2nd items above, check the troubled area in detail in accordance with the fault analysis method by symptom.
Page 15: Fault Diagnosis By Symptom
4-3 Fault Diagnosis by Symptom 4-3-1 No power (no display) 1) Checkpoints (1) Is the voltage of the power source normal?(AC 187V - AC 253V) (2) Is the power line in good contact? (3) Check the power fuse(F701, F702) and PCB fuse(F101) for open. (4) Are the primary and secondary sides of the power-trans in good contact with the connector? (5) Is the output voltage of REG1(KA7812) normal?(DC 11.5V - DC 12.5V) (6) Is the output voltage of REG2(KA 7805) normal?(DC 4.5V - DC 5.5V)
Page 16 4-3-2 When the indoor fan motor does not operate. 1) Checkpoints (1) Is the voltage of the power source normal?(AC 187V-AC 253V) (2) Is the indoor fan connector (CN71) in good contact? (3) Is the starting condensor of the fan motor in good contact with the terminal? (4) Is the resistance at both ends of the relay coil approximately 400Ω? 2) Checking procedures(after checking the checkpoints of clause 1) Turn off the power, and then turn it on in 5 seconds.
Page 17 4-3-3 When the compressor does not operate 1) Checkpoints (1) Is the voltage of the power source normal?(AC 187V - AC 253V) (2) Is the desired temperature set at a higher level than the current temperature at the time of “Cool”...
Page 18 4-3-4 When the Remote Controller Does not Operate 1) Checkpoint The sounds “beep” when it receives the signal of the remote control. 2) Checking procedures Turn off the power, and then turn it on in 5 seconds. Is room temperature displayed on the temperature Refer to the checkpoint when the indicator and does the operation start when pressing the power is not supplied.
Page 19: Pcb Inspection
4-4 PCB inspection 4-4-1 Inspection precautions 1) Be sure to check whether the AC sub power switch is removed when removing the main PCB or panel PCB. 2) Do not hold the outside of the main PCB or panel PCB with the hand or apply excessive force to it. 3) When connecting or removing the connector to the main PCB or panel PCB, do not pull the lead wire, but hold the entire assembly with the hand.
