(182°C). Place the thermometer in the oil above the tip of the fryer’s temperature probe with in
1” (2.54 cm) 25.4 mm). Be sure not to touch the heat tube since this will measure incorrect
temperatures.
Check that the controllers set point and thermometer is within +/- 5F (2.8°C). If your
measurement are off, re-measure again before contacting an Authorized Service Company
for further assistance.
