sides of islands) as shown in
Figure 1.

2Locate and remove the shipping
block in the center of the heat
exchanger in the interior bottom
of each case, see Figure 2.
Snap a chalk line on the floor to
use as a guide for positioning
the front of the cases in the line-
up. The front base frame should
be on the chalk line.
3Once cases are close to final
placement, remove the shipping
braces from the ends to be
joined, see Figure 3. Discard
bolts and flat washers used to
hold shipping braces. Bolts
are too long to be used for
joining.
