press the SW801 and the SW802 at the same time for 5 sec. (The
procedure will set back to step 3.) However, do not execute the operation

Notes
•
It sometimes takes about 30 minutes maximum for the check.
•
During the check, the compressor and the fan of the outdoor/indoor
unit repeat ON/OFF.
•
You cannot check wiring/piping when the external temperature is 5°C
or less. Also, there is a possibility to misjudge if the indoor
temperature becomes too low by cooling operation. In that case,
execute the cooling operation for per room and check if the
connection is normal.
