● ● Wrap indoor units’ flare joints with heat insulating parts (pipe cover) for heat insulation (both gas and liquid pipes). Give heat insulation to both gas and liquid side pipes. Bundle a heat insulating material and a pipe tightly together so that no gaps may be left between them and wrap them together with a connecting cable by a dressing tape. Both gas and liquid pipes need to be dressed with 20 mm or thicker heat insulation materials above the ceiling where relative humidity exceeds 70%.

'09•SRK-DB-087D Reference 2 TROUBLESHOOTING PROCEDURES FOR ELECTRICAL EQUIPMENT (1) Cautions (a) If you are disassembling and checking an air conditioner, be sure to turn off the power before beginning. When working on indoor units, let the unit sit for about 1 minute after turning off the power before you begin work.
'09•SRK-DB-087D (4) Troubleshooting procedure (If the air conditioner runs) Conf irm the contents of the customer complaint. NO The cause of the trouble can be specifically identified. Eliminate the cause of the trouble and perform an operation check. Check the self-diagnosis display. See page 41. Is an error code displayed by the self-diagnosis function? YES Using the Service mode, access the self-diagnosis displays generated in the past. NO See pages 42 ~ 48.
'09•SRK-DB-087D (5) Self-diagnosis table When this air conditioner performs an emergency stop, the reason why the emergency stop occurred is displayed by the flashing of display lights. If the air conditioner is operated using the remote controller 3 minutes or more after the emergency stop, the trouble display stops and the air conditioner resumes operation.
'09•SRK-DB-087D (6) Service mode (Trouble mode access function) This air conditioner is capable of recording error displays and protective stops (service data) which have occurred in the past. If self-diagnosis displays cannot be confirmed, it is possible to get a grasp of the conditions at the time trouble occurred by checking these service data.
'09•SRK-DB-087D *3: To count the number of flashes in the service mode, count the number of flashes after the light lights up for 1.5 second initially (start signal). (The time that the light lights up for 1.5 second (start signal) is not counted in the number of flashes.) ’’ In the case of current cut (example: stop code 42’’) The RUN light (10’s digit) flashes 4 times and the TIMER light (1’s digit) flashes 2 times. 4×10＋2×1＝42 From the table, read the instructions for error code 42, current cut’’.
