Assembly Replacement Procedures
Fan Assembly
Replacing a Fan
1. Refer to Figure 18-64. To replace a fan, it is necessary to remove the 4
plastic rivets (3) that attach the fan (1) and guard (2) to the fan bracket.
To do this use a small screwdriver to unscrew the rivet and remove it from
the bracket. The rivets may need to be cut or pushed out from behind.
They are not reusable.

2. Position the new fan on the work surface with the arrows pointing to the
right and down.
3. Orient the fan guard so that the rings are on the outside, and that the “V”
of the support legs are pointing to the neighboring fan.
4. With the rivets center posts raised, snap the rivets into place through the
fan grill and fan bracket and into the fan. Screw the center posts into
place. This may require a small hammer or push tool to push the rivets in.
