"green" dot for "right". When reconnecting
harness insure that red dots connect to left hand
components and green dots to right hand
components.

6. Stop agitating and allow fryer to cycle On and Off

automatically three (3) times.

7. After the stabilizing period, the instant the element

actuates (as noted by the fryer "On" light turning
on), the shortening temperature should be plus
or minus 5°F. (-15°C) of the thermostat setting.

8. If it is within ± 5°F. (-15°C) you are finished
calibrating.

9. If not, loosen the set screw in the temperature
control knob. Rotate knob without moving shaft
and set the knob, to match the pyrometer
reading.

10. Retighten the set screw.

DO NOT OVERTIGHTEN.
