13.
Position the rack-mounting plates within the marked areas.
14.
Mark the floor at the center of each hole in the rack-mounting plates
(including the tapped holes).
15.
Remove the two rack-mounting plates from the marked locations.
16.
At the marked location of the tapped rack-mounting bolt holes, drill four
holes approximately 5 cm (2 in.). This allows clearance for the ends of the four
rack-mounting bolts. The ends of the rack-mounting bolts protrude past the
thickness of the mounting plate.
Note:
You must use a minimum of two anchor bolts for each rack-mounting
plate to attach it to the concrete floor. Because some of the holes in the
rack-mounting plates might align with the concrete reinforcement rods that
are below the surface of the concrete, some of the rack-mounting plate holes
might not be suitable.
17.
For each rack-mounting plate, select at least two suitable holes. Select holes as
close to the threaded holes as possible. Be sure that the holes you select at the
rear of the rack are accessible. Drill the selected holes (two for each
rack-mounting plate).
18.
Position the front rack-mounting plate within the marked area.
19.
Using anchor bolts, attach the front rack-mounting plate to the concrete floor.
Note:
Do not use the four plastic isolator bushings.
20.
Position the rack over the front rack-mounting plate.
21.
Position the rear rack-mounting plate within the marked area.
22.
Using anchor bolts, attach the rear rack-mounting plate to the concrete floor.
23.
Insert each of the rack-mounting bolts through a flat washer, a thick washer,
and through a leveling foot.
24.
Align the four rack-mounting bolts with the four tapped holes in the two
rack-mounting plates and turn the bolts 3–4 rotations.
25.
Tighten the locking screw on each caster.
26.
Adjust the leveling screw downward, as needed, until the rack is level. See
Figure 65 on page 214. When the rack is level, tighten the jam nuts against the
base by turning the jam nut clockwise, toward the bottom of the rack. Torque
the four bolts to 54–67 nm (40–50 ft-lbs).
