  • Page 54: Maintenance Data

    '20 • DXK-T-321 10. MAINTENANCE DATA (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. When working on an out- door unit, there may be an electrical charge applied to the main circuit (electrolytic condenser), so begin work only after discharging this electrical charge (to DC 10 V or lower).

  • Page 55: Troubleshooting Procedure (If The Air-Conditioner Runs)

    '20 • DXK-T-321 (4) Troubleshooting procedure (If the air-conditioner runs) Confirm the contents of the customer complaint. The cause of the trouble can be specifically identified. Check the self-diagnosis display. Eliminate the cause of the trouble and perform an operation check. See page 55.

  • Page 56: Self-Diagnosis Table

    '20 • DXK-T-321 (5) Self-diagnosis table When this air-conditioner performs an emergency stop, the reason why the emergency stop occurred is displayed by the flash- ing of display lights. If the air-conditioner is operated using the wireless remote control 3 minutes or more after the emergen- cy stop, the trouble display stops and the air-conditioner resumes operation.

  • Page 57: Service Mode (Trouble Mode Access Function)

    '20 • DXK-T-321 (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 oc- curred by checking these service data.
