Note:
1.The outdoor failure can also be indicated by the indoor unit,the checking method as follows: LED6 flash times
stands for ten's place,and LED1 flash times stands for one's place,use this ten-digit number minus 20,then will
get the outdoor error code.For example,if the outdoor error code is 15,LED6 will flash 3 times firstly,two seconds
later,LED1 will flash 5 times , and four seconds later the process will repeat again.
2.LED6 is a green one on the indoor PCB,LED1 is a yellow one.
3.To get much more details about the out door unit failure,please refer to the outdoor unit trouble shooting list.
