Disconnect unit from electric power and allow to cool. Remove grate. 2. Remove front and rear element covers. Note location of jumpers and wires. SUGGESTION: Removing a pivot will allow the element head to be tipped on its side for better access to the element connection screws. 3. Disconnect jumpers and wires from element to be removed. Remove short jumpers from the front of all elements. Remove element nuts from the front end of all elements. Slide the front element support frame off of the elements. 4. Remove the rear element nut from all elements to be replaced. Withdraw the old element from the rear element support frame and discard. 5. Apply a small amount of anti-sieze to the element threads, then attach the element to the rear element support frame. NOTE: The element mounts such that the end with the shoulder is positioned at the rear, the "flat" of the element is down, and the electrical connection pad is toward the bottom. 6. Examine all rear elements for proper alignment, and all rear element nuts for tightness. 7. Thread an element nut on the front end of the new element. Run the nut inboard until a single thread remains exposed. Examine all the other inboard element nuts to verify that only a single thread remains exposed on each. IMPORTANT: Review page 7 for procedure on reinstalling pivots. 9. Reconnect all jumpers and wiring. Reinstall element covers. If any pivots were removed or loosened, be sure element support bar is fully forward before reinstalling the element assembly on the pivots. 10. Reconnect to electric power and test for proper operation. Reinstall grate. 8 SV161 SvcManual Electric Char-Broilers SUGGESTION: At the rear element connections, install upper group of jumpers first, then install lower group. Installing jumpers in this order will ease accessibility conflicts. 8. Slide the front element support frame over the elements. NOTE: Position front element support frame such that the cover mounting holes on its face are at the top, and the edge with the cover mounting slot and threaded tabs is at the bottom. Loosely reinstall all front element nuts. Adjust front and inboard element nuts until the front and rear element support frames are the same distance apart on right and left ends. Tighten front and inboard element nuts evenly.
