Inspection
● Reinstallation of the fan
After confirming the orientation of the fan, reinstall the fan so that the arrow on the left of
"AIR FLOW" faces up.
NOTE Installing the fan in the opposite air flow direction can cause the inverter life to be shorter.
Reconnect the fan connectors. When wiring, use care to avoid the cables being caught by
the fan.
