Calibration of the Griddle Thermostat
Equipped with commercial duty snap action electric thermostats, these units are designed to open on temperature rise.. Field
NOTE: NO ATTEMPT TO RECALIBRATE THE GRIDDLE CONTROL SHOULD BE MADE WITHIN THE WARRANTY PERIOD.. IF
THE CONTROL IS OUT ± 20° F FROM THE DIAL SETTING, THE CONTROL WILL BE REPLACES UNDER WARRANTY.. IF SOMEONE ATTEMPTS RECALIBRATION DURING THE WARRANTY PERIOD THERE WILL BE NO WARRANTY ON THE CONTROL THAT WAS TAMPERED WITH..
Calibration Instructions
1.Use a test instrument (surface pyrometer) with a special disc type thermocouple or reliable “surface” type thermometer.. Note: A drop of oil on the face of the disc will provide better contact with the griddle plate..
2.Turn all griddle thermostats to 350° F (177° C).. In order to allow the griddle temperature to stabilize the controls must be allowed to cycle three times before taking a test reading..
3.Check the temperature reading when the thermostat cycles off by placing the sensor firmly on the center of each section of the griddle surface.. Take a second temperature reading when they thermostat cycles back on.. Make a note of this reading.. The average of the two readings should be ± 20° of 350° set temperature..
If the average is more than the 20° tolerance, recalibrate as follows..
4.Carefully remove the thermostat dial, not disturbing the dial setting..
5.Hold the dial shaft steady and with a screwdriver turn the calibration screw, (that is located inside the thermostat shaft), clockwise to decrease and
6..Replace the thermostat dial and repeat steps 1 through 3 to verify if the correct adjustment has been made..
