4. Carefully remove the thermostat dial, not disturbing the
dial setting.
5. Hold the thermostat shaft steady and with a small flat
blade screw driver, turn the calibration screw located
inside the shaft clockwise to decrease the temperature
or counter-clockwise to increase the temperature.
Note each 1/4 turn of the screw will create a change of
approximately 25°F.
6. Replace the thermostat dial and repeat steps 1 through 3
to verify that the correct adjustment has been made.
Griddlethermostat
1. Use a test instrument with a special type thermocouple
or a reliable surface type pyrometer. Note: a drop of oil on
the face of the disc will provide better contact with the
plate.
2. Set all griddle thermostats to 300°F. In order to allow the
griddle temperature to stabilize, the thermostats must be
allowed to cycle twice before taking a test reading.
3. Check the griddle temperature when the thermostat just
cycles “OFF” by placing the thermocouple firmly on the
griddle surface directly above the sensing bulb of the
thermostat. The reading should be between 285°F and
315°F. If the reading is outside of these limits, calibrate as
follows:
