Note:
1. The outdoor failure can also be indicated by the indoor unit, the checking method as follows: If the outdoorerror
code is M (DECIMAL) , the indoor unit's I.R. receiver display will show the after converted hexadecimal code of
"M+20" (DECIMAL) , for example, if the outdoor error code is 2, the indoor unit I.R. receiver display will flash the
error code 16 (2→2+20=22→change deciaml 22 to hexadecimal code, get 16)
2. LED4 is a red 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.
