Install a new fan in such a way that the fan cable comes out from the lower right when viewed
from the front.
Have enough clearance to prevent the cables from being caught in the blades of the fan.
After fan replacement is completed, reinstall the CCU into the display unit mount kit by repeating
the same procedure in the reverse order. Please make sure to tighten all the screws and connect
all the cables back in place.
Step 3 Check operation.
After fan replacement is completed, turn ON the circuit breaker for the power supply of the
display unit and check the operation as follows.
(1) Turn ON the display unit and start the MFD application. Check that there is no problem
in its operation and processing.
(2) Check that the fan alarm "CCU (Fan)" does not occur.
This completes fan replacement.
