For a retro-fit installation, remove the original washers and height adjustment nuts from
the existing foundation plate and then place a Half-nut and a Bottom Height Adjuster
onto each existing Mounting Bolt, as shown in Figure 37.
Note the orientation of the
Bottom Height Adjusters.
If the existing unit
was mounted with the
maximum clearance to
the foundation plate, the
new unit will require that
the rack be re-adjusted to
obtain the correct mesh
between the rack and
