CAUTION
•
Installing the fan in the opposite of air flow direction can cause the inverter life to be shorter.
• When installing the fan, use care to prevent wires from being caught between the inverter and fan.
• Switch the power OFF before replacing fans. Since the inverter circuits are charged with voltage even after power
OFF, replace fans only when the inverter cover is on the inverter to prevent an electric shock accident.
