Note:
1.The outdoor failure can also be indicated by the indoor unit,the checking method as follo- ws: LED4 flash times stands for
tens digit,and LED3 flash times stands for units digit, use this bidigitate figure minus 20,then will get the outdoor error code.
For example,if the outdoor error code is 15,LED4 will flash 3 times firstly,two seconds later,LED3 will flash 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.
