Step 1: Unplug the laminator.
Step 2: remove the left side housing. See Upper Heat Shoe removal Instructions (pg 16).
Step 3: loosen, but do not remove the small set screw on the bottom of the lower heatshoe
(Photo 25-1).
Step 4: Unplug the two blue leads from the bottom of the thermostat.
mark where the leads went to ease reassembly.
Step 5: remove the two screws retaining the thermostat bracket to the laminator. note: the motor-run capacitor is
also retained by one of these screws (the long one). When removing this screw and repositioning the capacitor to gain
access to the thermostat use caution. do not touch the terminals on the capacitor or allow them to contact any metal
part of the laminator. contact USI for any further information on servicing the capacitor.
(Photos 25-2 & 25-3).
Step 6: Gently pull the thermostat away from the laminator.
Step 7: loosen, but do not remove the two screws retaining the left end of the lower heatshoe
(Photo 25-4).
Step 8: Grasp the capillary tube and gently slide the heat-sensing bulb out of the heatshoe.
Step 9: to install the new part, remove the mounting bracket from the old thermostat and attach it to the new part. the
bracket is held on with two screws on either side of the adjusting knob.
Step 10: Slide the heat-sensing bulb into the opening on the end of the lower heatshoe. Snug the small set screw on
the bottom of the lower heatshoe. do not over-tighten as this could cause damage to the bulb (Photo 25-1).
Step 11: tighten the two screws retaining the lower heatshoe (Photo 25-4).
Step 12: Gently coil the capillary tube between the thermostat and the side frame. Use caution not to break or crimp
the capillary tube (Photo 25-5).
Step 13: re-fasten the thermostat bracket to the laminator. When doing so, use the long screw on the left-hand side
of the thermostat to hold the motor-run capacitor. Position the capacitor so the top (terminal end) is angled toward the
rear of the laminator. Use caution not to touch the terminals or allow them to contact any metal part of the laminator
(Photo 25-6).
Step 14: Plug the two blue leads into the new thermostat.
Step 15: reinstall the side housing, heat control knob, and switch plate.
