into the upright. Using a 3 mm hex key, reinstall the side roller bracket. To make sure it is properly
seated in its tracks, move the rail assembly through its full range of travel to make sure it does not
hang-up or bind before reattaching the upright to the device.
3. To assist in reattaching the upright to the device, there are four studs on the bracket casting that mate
with four holes in the upright. Place the upright on the studs. Be sure the radiant heater bracket is in
front of the upright. Be careful not to pinch any wires between the device and the upright.
4. Secure the upright to the device by reinstalling the 2 screws in the holes inside the upright. Pull any
excess wiring slack in the upright channels into the electrical enclosure.
5. Push the lift rail down into the upright until the rail locking screws align with the horizontal oblong holes
in the rail. Lock the rail by turning the screws CCW (4 mm hex key) until they lock the inner rail in place.
6. Attach ground wire to rail. Fasten the display module to the upright with the two screws and nut bar
removed earlier.
7. Reinstall the wire cover. Take care to route the wires in the upright channels and not to pinch them with
the cover when securing with the screw.
8. Remove the Display head assembly by following the steps in “Display Head Removal” on page 7-17.
9. Reinstall the decorative strip and the two end caps.
10. Fasten the control panel cover to the back of the enclosure.

15. Release the intermediate rail locks by tightening the set screws so that the screw heads disengage
from the horizontal oblong holes in the uprights.
7.5.5 Replacement of the Left Upright Heater Wire Harness/Cable Carrier Assembly
The heater wire harness/cable carrier assembly (6600-0710-700) includes both the wire harness and the
cable carrier. The end links of the cable carrier are riveted to the lift rail and the cable carrier channel (2 pop
rivets at each end). The easiest way to replace the harness is to reuse these end links of the cable carrier. If
the end link of the cable carrier is damaged, there are two options:
• Replace the entire left upright assembly (6600-0288-851). (Refer to section 7.4.2)
• Drill out the rivets that secure the broken link to the lift rail or Cable carrier channel. Remove the end link
from the new assembly and rivet it in place. Then follow the instructions below. Two rivets are required
for each end of the cable.

The 3-pin MAT-N-LOK connector for the radiant heater connections must be removed from the old harness
using a pin extractor. If a pin extractor is not available, order a new connector when you order the harness.
Four cable ties are also required..
