1) After confirming the orientation of the fan, reinstall the fan so that the arrow on the left of "AIR FLOW" faces up.

CAUTION
•
Installing the fan in the opposite air flow direction can cause the inverter life to be shorter.

replace fans only when the inverter cover is on the inverter to prevent an electric shock accident.
