Note:
1. The outdoor failure can also be indicated by the indoor unit,the checking method as follo- ws: LED4 ash times
stands for tens digit,and LED3 ash times stands for units digit, use this bidigitate gure minus 20,then will get
the outdoor error code.For example,if the outdoor error code is 15,LED4 will ash 3 times rstly,two seconds
later,LED3 will ash 5 times , and four seconds later the process will repeat again.
2. LED4 is a yellow one on the indoor PCB,LED3 is a green one.
3. To get much more details about the out door unit failure,please refer to the outdoor unit trouble shooting list.
