Note:
1.The outdoor failure can also be indicated by the indoor unit,the checking method as follo-
ws: LED4 flash times stands for ten's place,and LED3 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,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.
