to center the rod in the oval opening, then keeping the rod vertical is
more important.
11 For each remaining oval opening that does not have an anchor rod
passing through it, fasten a plate over the opening so that no gap appears.
The plates are square with a screw hole in one corner. The frame base
has a screw hole beside the inner oval openings. Fasten each plate using
a provided thread-forming 10-mm (3/8-in.) hex-head screw.
12 Starting at a middle anchor (if any) and moving outwards in a spiral,
tighten all nuts.
For M12 anchors, torque each nut to 78 Nm (58 lbs-ft) using an 18-mm
(23/32-in.) 6-point deep socket.
For 10-mm (3/8-in.) anchors, torque each nut to 48 Nm (36 lbs-ft) using a
16-mm (41/64-in.) 6-point deep socket.
13 After fastening the anchors, the levelling feet may no longer touch the
floor. Check each levelling foot to ensure it touches the floor. If not, tighten
each until it touches, then tighten a 1/4 turn more.
You may need to level the frame again by unfastening the anchor nuts,
adjusting the levelling feet, and re-fastening the anchor nuts.
14 Under the floor tiles, thread each 18-mm (23/32-in.) nut up the rods until
the washer is snugly against the underside of the floor tile, as shown in
the figure “Anchoring to a raised floor” (page 235). Then tighten each nut
another 1/4 turn.
15 Fasten each kick plate back on the frame base.
