NOTES:
1. Since the outdoor side electric wiring may change be sure to check the outdoor unit electric wiring for servicing.
2. Indoor and outdoor connecting wires are made with polarities, make wiring matching terminal numbers (1, 2, 3).
3. Symbols used in wiring diagram above are, : Connector, : Terminal (block).
[Self-diagnosis]
1. For details on how to operate self-diagnosis with the wireless remote control, refer to the technical manuals etc.
2. For the wired remote control : When you quickly press twice the CHECK switch on the remote control, the unit begins self-diagnosis, and Check Codes generated in the past appear on the display. For Check Codes and Symptoms refer to the table.
[Emergency operation procedure]
1.When the indoor unit microcomputer has failed, but all other components work properly, if you set the switch(SWE,SW6)on the indoor control board, the indoor unit will begin Emergency Operation.
2.When you activate emergency operation of the cooling you have to set the switch(SWE)and switch(SW6)on indoor controller.
SWE:ON ·Indoor fan is running high speed.
·Drain-up machine(optional)is working. SW6-1:ON ·Emergency operation of cooling mode.
3.Before you activate emergency operation, check the following points: (1) Emergency operation cannot be activated when:
· The outdoor unit malfunctions. · The indoor fan malfunctions. (2) Emergency operation becomes continuous only by switching the power source on / off. ON / OFF on the remote control or temperature control etc. does not function. (3) Emergency cooling should be limited to 10 hours maximum (The indoor unit heat exchanger may freeze). (4) After emergency operation has been deactivated, set the switches etc. to their original positions. (5) Movement of the vanes does not work in emergency operation, therefore you have to slowly set them manually to the appropriate position.
