Replacing the Cooling Fan
If a cooling fan fault (E07) is displayed, or if the cooling fan needs replacement, take the following
steps to replace it.
1.Remove the fan cover mounting screws.
2.Insert a flat-blade screwdriver into the slot (indicated by “A”), and pull off the fan cover in the di-
rection indicated by “1.”
3.Remove the fan and pull out the fan connector (in the direction indicated by “2”) from the socket
on the board side in the case. Do not pull on the wires alone. Doing so may break the wires.
4.Insert the connector for the new fan into the socket on the board side in the case.
Position the connector so that the connector latches are aligned.
5.Secure the fan in the case.
Check that the wiring direction is as shown in Fig. 2, and mount the fan with the seal facing out-
wards.
6.Replace the fan cover and tighten the mounting screws.
The cooling fan replacement is now complete.
