5.
Remove the mounting hardware that was installed
in Step 3.
6.
Slide the OV forward, exposing the marked
mounting locations.
7.
Using a ⅝" concrete drill bit, drill four anchor holes,
3" in depth, at the center of each marked location in
Step 4.
NOTES
The anchor hole(s) must be clean before installing
the anchor bolt(s). If the hole(s) are not clear of
debris, the anchor bolt(s) may not tighten correctly.
8.
Insert anchors into the drilled holes. The threaded
end of the anchor must be inserted into the hole
first. Use a hammer to tap the anchor into place,
if needed. Ensure that the anchors are flush with the
concrete floor.
9.
Slide the OV backward, exposing the marked
mounting locations for the remaining base plate.
10. Repeat Steps 7 and 8.
11. Place the OV back over the anchor holes and
anchor it with eight ⅜" x 2½" anchor bolts and flat
washers (Figure 18).
12. Insert two 1½" mounting bolts and two mounting
nuts up through the mounting holes (Figure 17A)
Tighten using a ¾" socket and socket wrench.
13. Confirm OV is level and plumb. Shim as needed.
14. Once the OV has been anchored, use a socket
wrench and 9/16" socket to tighten all anchor bolts
(Figure 18).
15. Apply a thick bead of clear RTV silicone around
both base plates.
16. When complete, refer to Figure 19 for correct
orientation.
NOTE
Clear RTV silicone is a low volatile formula and can
be used in a variety of applications.
