Read oil temperature.
Insert the fry vat probe of the
pyrometer into the hot oil to
within 1 inch (2.5 cm) of the

be approximately 3 inches
(7.6 cm) below the surface of
the oil. Allow the temperature
reading to stabilize.

Display temperature on fryer.
Press the temperature display
switch for the vat where you
took the pyrometer reading.
The display will show the

Compare temperature
readings.
Compare the temperature
reading on the pyrometer with
the corresponding tempera-
ture on the display.
If the two temperatures are
less than 5°F (3°C) apart (ei-
ther plus or minus), you do
not need to adjust the tem-
perature setting.
If the two temperatures are
more than 5°F (3°C) apart
(either plus or minus), call a
service technician to report
the problem.

of the split-vat.
