" " " " Reinstallation
1) After confirming the
orientation of the fan,
reinstall the fan to the
cover so that the arrow on
the left of "AIR FLOW"
faces in the opposite
direction of the fan cover.
Note: If the air flow is set
in the wrong
direction, the
inverter life can be
shorter.
2) Reinstall the fan cover to
the inverter.
Run the cable through the
wiring groove to prevent it
from being caught
between the chassis and
cover.
3) Reconnect the cable to the
connector.
4) Reinstall the inverter front
cover.
