nectors.

13. Remove the original icker motor and remove the

rubber barrier that mounts between the motor and the bracket.

14. Fit the rubber barrier onto the new icker motor and

mount the icker motor onto the mounting bracket. Reconnect the rubber gasket and icker rod to the icker

motor.

NOTE: Ensure that the icker rod is not bent and the bushing in the center of the icker rod is completely set in

the support bracket. The bushing must be properly aligned

for it to go all the way down into the bracket.

15. Reconnect the icker motor wires, according to their

original conguration.

16. Re-assemble the remainder of the replace in reverse order from the instructions above.

NOTE: If any tie wraps were removed, replace and en-

sure that none of the wires are pinched during reassembly.

NOTE: Be sure that the anges on the end panel are

positioned on the interior of the outside panel of the re-

place.

1. On either side of the rebox, remove the retaining

screws and carefully remove the glass assembly from

the rest of the assembly. (Figure 3)

2. Carefully remove the acrylic media from the front tray.

3. If applicable, remove the replace assembly from the

wall by carefully lifting it upward, releasing it from the

anges of the wall-mounting bracket. (Figure 4).

4. Carefully set the unit upright on a at working surface.

NOTE: If necessary, lay a protective barrier between the unit and your work surface, (i.e. cloth, cardboard, thick plastic) to avoid scratching your work surface.

5. On the right end, with the switchboard, remove the ten

screws around the outside of the end panel. (Figure 5)

6. Lay unit on its back and remove the remaining 9 screws

from the end panel.

7. Remove the end panel being careful not to add any

strain to the wires connecting to the switchboard.

8. Gently guide the partially reective glass out the open

side of the rebox.

NOTE: The wires are grouped together with tie wraps,

which may need to cut to easily access the different wires.

9. Remove both sets of the 3 end panel screws and the 5

front screws that hold the Media Tray in place. (Figure

10. Remove the 5 screws that hold the LED light bracket

onto the bottom of the rebox. (Figure 10)

11. Remove the 2 screws holding the LED light strip to the

bracket, lay the new LED light strip back into the light bracket and secure.

12. Trace the wires from the original LED light strip up to

the LED driver board, replacing them with the new wires and any new tie wraps as required.

13. Remove and replace the wire connectors from the terminals on the LED driver board.

NOTE: Use a at head screwdriver to gently pry

between the end of the connector and the switch to release the wires.

14. Remount the LED light strip bracket onto the rebox.

15. Re-assemble the remainder of the replace in reverse order from the instructions above.

NOTE: If any tie wraps were removed, replace and en-

sure that none of the wires are pinched during reassembly.

NOTE: Be sure that the anges on the end panel are

positioned on the interior of the outside panel of the re-

place.
