Caution!
In the event of abnormal conditions (like stinky smell), please shut off the power supply
immediately and then contact the appointed service center; otherwise, the abnormal running
would damage the air conditioner and also would cause electric shock or fire etc.
Do not repair the air conditioner personally but instead of contact the professionally skilled
personnel at the appointed service center, as the incorrect repair would cause electric shock or
fire etc.
