Service Diagnosis
(5) Precautions for operating in servicing mode (field setting):
When a test operation is interrupted or after exiting service mode, please wait for at least one minute before entering
service mode again. In case of continuous execution, the outdoor unit PCB may sometimes display an error code. If any
error codes are displayed, press the
RETURN (BS3)
button. If performing the above operation still does not eliminate
the error, reconnect the unit to the power supply.
