6. Position the table as close as possible to the center. Attach the
measuring bar provided to the brass spacers mounted onto the
bearing. Note the appropriate hole-mount locations in reference to
the size of the turntable to be installed. Rotate the bearing and
ensure approximately
7/8 ” to 1” spacing exists between the edge of
the outer measuring bar and the diameter of hole cut into the pit.
Adjust if necessary.
7. Once the center is located, using a marker, mark around the
perimeter of the table base or outer floor plates. These marks may
be used for reference if the assembly moves during placement of
the floor shims or anchor plates.
NOTE: When installing the turntable on modular shielding, attempt
to make as many anchor holes miss the floor joint strips as possible
when positioning the table. Use the shim plates provided for this
application.
8. The Model 2188 turntable includes curved floor anchor plates that
are under the base unit. The 1.5m and 2.0m model includes an
outer ring of floor plates to support additional casters. Place
between the base unit and outer plates, the four connector strips
included to ensure proper spacing. Please refer to drawing number
2188-1.2, 2188-1.5 or 2188-2.0 included at the back of this manual
and figure two for the placement and securing of floor plates. If the
turntable is to be installed in a welded chamber with a steel pit and
steel raised floor, please refer to step 12.
3.4. Installing Anchor Plates
9. The anchor plates are held in place by ¼-20 screws and set collars.
Screw the anchor plates to the floor using #14x1” #3 square socket
flat head screws. Drill
1/8 ” pilot holes for these screws and vacuum
up shavings so that you have good contact with the floor. Continue
mounting the rest of the plates.
10. Once all anchor plates are securely mounted, remove the ¼ -20
screws that hold the anchor plates to the base and discard.
11. Proceed to level the table to the raised floor.
