Procedure steps
1 The parts of each anchor are loosely assembled in the anchor kit. Put one
aside to use as the example to fasten the others to the frame.
2 Remove from the threaded rod anchor assembly the items 1 to 6 in the
figure “M12 anchor assembly” (page 234). Lay them out in sequence. If
present, shims are not used.
3 Unfasten the 2 captive screws of each kick plate at the front and rear of
the frame base. This enables easier access above the frame base.
4 Remove the tape from covering the anchor holes.
5 For each threaded rod to be installed, it must be measured and cut as
follows.
• From an uncut end of each threaded rod, mark a length to
accommodate the anchor, for example, 10 cm (4 in.) as shown in the
figure “M12 anchor assembly” (page 234). If the anchor holes are
deeper than this measurement, you must plan to either have the
anchor sit flush with the floor or at the bottom of the hole. If you
choose the bottom, you must measure the depth of the hole and
mark the difference on the rod.
• From a specific hole intended for the rod, measure the perpendicular
distance between the floor at the hole and the base of the frame at
the oval opening. Mark the same distance on the rod above the mark
for the anchor length.
• Add 7.5 cm (3 in.) above the second mark to indicate the length that
the rod is to pass above the base of the frame into the kick-plate
cavity.
• Cut the rod at the last mark. File the thread pitch so that its nut can
thread onto the rod easily.
CAUTION
Risk of damage by fire
In the bottom rear center of the frame, each removable
plate (drip tray, part number P0870734) may have two
knockout disks. Each knockout disk must remain intact
and unbent unless a power conduit from a raised floor will
be routed through it. Leaving an opening reduces the fire-
proofing of the Passport 15000 or 20000.
