5.1.4 Clean Detachable Parts and Accessories – Weekly
Wipe all detachable parts and accessories with a clean, dry cloth. Use a clean cloth saturated with
detergent to remove accumulated carbonized oil on detachable parts and accessories. Rinse the parts
and accessories thoroughly with clean water and wipe dry before reinstalling.
5.2 Check Calibration of Temperature Control Knob – Monthly
1. After the cooking oil reaches operating temperature, let the heating elements cycle at least four
times (indicated by the HEAT light going out and coming back on).
2. Insert a thermometer or pyrometer probe near the temperature-sensing probe approximately five
inches deep into the cooking oil. When the heating elements cycle on for the fourth time, the
thermometer should read within ±5°F of the temperature control knob setting.
3. If the knob requires adjustment:
a. Loosen the setscrew in the control knob until the outer shell of the knob will rotate on the
insert inside the knob.
b. Rotate the outer shell of the knob until the index line on the knob aligns with the mark that
corresponds to the thermometer or pyrometer reading.
c. Hold the knob and tighten the setscrew.
d. Recheck the thermometer or pyrometer reading and the temperature control knob setting the
next time the HEAT light illuminates.
e. Repeat steps a through d until the thermometer or pyrometer reading and the knob setting
agree within 5°F.
