1.6.2 Backup Operating Thermostat (Optional)
1. Fill the frypot to the lower OIL-LEVEL line with oil. If solid shortening is used, it must be
melted before starting the calibration procedure.
2. Light the pilot.
3. Set the temperature control knob to 350°F/177°C.
4. Let the burners cycle on and off automatically three times in order for the cooking oil
temperature to become uniform. If necessary, stir to get all shortening in the bottom of the
frypot melted.
5. Insert a thermometer or pyrometer probe into the oil, with the end near the fryer temperature-
sensing probe.
NOTE: The temperature-sensing probe is mounted on the frypot tube.
6. When the burner starts for the fourth time, the thermometer/pyrometer reading should be within
the range 335-360°F (168-182°C). If it is not, calibrate as follows:
a. Remove the thermostat knob by pulling straight out on the knob with a firm, steady pull.
The temperature adjusting screw is located in the middle of the thermostat shaft.
b. Insert a small-bladed flat-tipped screwdriver into the adjusting screw. Turn the adjusting
screw in ¼-turn increments to adjust the temperature. Turning the screw clockwise
decreases the temperature; turning it counter-clockwise increases the temperature. DO NOT
allow the thermostat shaft to turn while turning the adjusting screw.
c. Recheck the thermometer/pyrometer reading the next time the burner comes on.
d. Repeat steps 6.b. through 6.c. until the thermometer/pyrometer reading remains within the
range 335-360°F (168-182°C) through several cycles. If calibration cannot be obtained for
any reason, call a Factory Authorized Service Center for service.
e. Reinstall the thermostat knob.
7. Remove the thermometer or pyrometer.
