Thermal Cut-Out Replacement - usi 1800-2700 Owner's Manual

THERMAL CUT-OUT REPLACEMENT

1. Unplug laminator.
2. Loosen and remove four Allen head screws retaining both side housings; remove the side housings.
3. Unplug both thermal cut-out leads on the left end of the lower heatshoe. See diagram on page 29.
4. While supporting the lower heatshoe, loosen and remove the two heatshoe mounting screws and spacers from
the left end of the heatshoe.
5. Continue supporting the lower heatshoe and loosen and remove the two shoulder screws from the right end of the
heatshoe.
6. Gently rotate the lower heatshoe forward being careful not to disturb the wiring on the right end of the heatshoe.
7. Loosen but do not remove the hex screw on the back of the lower heatshoe retaining the thermal cut-out; pull the
thermal cut-out out of the heatshoe.
8. If the new thermal cut-out is not formed to the same shape as the old one, gently form a loop in it to match the
old one.
9. Insert the new thermal cut-out into the lower heatshoe and hook it on the hex screw. CAUTUION: Do Not pinch the
thermal cut-out under the hex screw; doing so will cause an electrical short. Be certain the thermal cut-out is
hooked over the hex screw.
10. Gently reposition the lower heatshoe on the machine and guide the thermal cut-out wires through the hole in the
left side frame. Pay special attention to the wiring on the right end.
11. Replace and tighten the two shoulder screws on the right end of the heatshoe. Replace and tighten the two
mounting screws and spacers on the left end of the heatshoe.
12. Plug the thermal cut-out wires into the appropriate terminals. The thermal cut-out must be plugged into the
correct terminals to work properly. See diagram on page 29.
13. Replace both side housings and secure each with four Allen head screws.
