CALIBRATION OF TEMPERATURE CONTROL
1. Ensure that pan is empty and clean before calibrating.
2. Place a surface thermometer on left or right rear sides, 3" from sides of griddle surface.
NOTE: Check that magnets on thermometer extend through holes in circular base plate and are in complete contact with
griddle surface.
3. Set temperature control knob at 375°F (191°C).
4. Allow skillet to preheat and stabilize 2–3 cyc
5. Record thermometer reading. If a temperature of 370°–380°F (188°–
193°C) is recorded, procedure is complete. If not, go on to step 6.
6. Remove control box cover by removing screw in rear and right side of cover.
7. Locate temperature control circuit board (see Figure 6.1) and calibrate as follows:
a. If temperature goes above 375 °F (191°C), turn setpot labeled HI
counterclockwise to decrease temperature.
b. If temperature goes below 375 °F (191°C), turn setpot labeled HI
clockwise to increase temperature.
NOTE: Turn the HI setpot only. Be careful when turning setpot—just a slight turn (approximately 22°) will change
temperature by 25°F.
8. Allow skillet to cycle three (3) times. This cycling allows temperature control to stabilize.
9. Record thermometer reading when pilot light goes out. If a temperature of 370°–380°F (188°–193°C) is recorded,
calibration procedure is complete. If not, repeat steps 7 and 8 until appropriate temperature is recorded.
10. Replace control box cover by pushing down and replacing screw in rear and right side of cover.
