Chassis support preparation
To prepare the chassis support for Model 707B or 708B installation:
1. Place a rear support bracket (item D) on the left chassis support (item A) and temporarily install
the two pieces in the rack by sliding them apart until the flanged ends fit as shown in the following
figure. Note which holes will be used to attach the two pieces together.

2. Use a spacer bar, nut bar, and two binder head screws (items E, F, and G) to loosely attach each
rear support bracket to a chassis support. The following figure shows the left side support.
