Check for successful completion of the refrigerant oil recovery operation.
Turn the dipswitches 1-4, 1-5, 1-6, and 1-7 to ON to verify that the refrigerant oil recovery operation is completed. “S-1” or “r-1” on

“S-1” “r-1”: The refrigerant oil recovery operation is successfully completed. Go to the next procedure.
“S-1” “r-0”: The refrigerant charge adjustment is not completed, but regular air conditioning operation can be started. If there was excess
refrigerant that had not been charged, charge it through the low-pressure check joint (CJ2) during the air conditioning operation.
“S-0” “r-1”: The refrigerant oil recovery operation is not completed. To restart the refrigerant oil recovery operation, set the dipswitches 3-1 and
4-8 to ON in that order.
