3.2.4.2 Narrow Hallway
If a Discovery unit must be moved through a hallway that is not at least 45" (114cm) wide,
the C-arm can be removed. This allows the unit to fit through a hallway 29" (74cm) wide
(inside dimension). See the instructions for removing the C-arm below.
3.2.5 Remove Tabletop (If Necessary)
Note: It is not necessary to remove the tabletop if the doorway that the unit must go
through is at least 81" (206 cm) high (top-to-bottom inside dimension). Removing
the tabletop allows the unit to fit through a doorway 79" (201 cm) high.
The tabletop can be removed before taking the unit off the pallet. Follow the procedure
below to remove the tabletop:
1. Remove the table pad and remove the right-side table rail end cover (2 Phillips
screws located on the right end). This cover slides straight out the side.
2. Remove the head end pedestal covers. You will need to move the table to its
extreme forward position to access the center screws on each panel.
3. Remove the two screws (Phillips) that secure the tabletop in place (located on top
of the table near the rear center) and slide the table to the left, far enough to
access the Table X-bearing blocks.
4. Referring to Figure 3-7, remove the right-side, front endcap (3 Phillips screws).
5. Remove the back Phillips screw from the right-side cover (of the table X-drive
assembly) and slide the cover out from the front.
6. Unplug the cable to the Motor Controller board.
7. Refer to Figure 3-7. Disconnect the stainless steel cable guard (2 screws) and
remove the Table X-drive attachment bracket (4 bolts and 2 nuts).
8. Remove the left rail stop (1 counter sunk screw located next to the left-side, front
endcap) to allow the tabletop to be rolled off from the front.
9. Remove the 8 Allen screws (6mm) holding the table X-drive bearing blocks.
10. Remove the tabletop by carefully sliding it off the front of the unit (requires two
people). Be careful not to slide the bearing blocks off the rail.
11. Refer to Figure 3-7. Install the right angle bracket (found in the miscellaneous
hardware kit) to hold the bearing blocks and X-drive bracket in place while the
scanner is moved. If this bracket is not available, tape the bearing blocks, and X-
drive bracket in place.
