ENGLISH SAFETY OVERVIEW Read These Safety Precautions Be sure to read the safety precautions before conducting work. The items are classified into “Warning” and “Caution.” The “Warning items are especially important since they can lead to death or serious injury if not followed closely. The “Caution” items can also lead to serious accidents under some conditions if they are not followed. Therefore, be sure to observe all safety precautions listed here.
SAFETY OVERVIEW Be sure to use the specified cable to connect between the indoor and outdoor units. Make the connections securely and route the cable properly so that there is no force pulling the cable at the connection terminals. When connecting the cable between the indoor and outdoor units make sure that the terminal cover does not lift off or dismount because of the cable.
