Be careful with the fan mounting direction. Be sure to install the fan so that the air flows out of
the monitor.
Have enough clearance to prevent the cables from being caught in the blades of the fan.
After replacing the fans, assemble to the original condition 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 Checking operation
After monitor 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 power to the display unit and make sure that screen display is normal.
