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.
