Check Calibration
12. Note: The computer should rarely be out of the ±5°F (±3°C) range, as it is preset at the
factory.
13. Repeat all the above steps for remaining fryers.
Check Calibration
1. Turn vat ON and set the thermostat knob to the correct cooking temperature.
2. Allow the vat to cycle OFF after reaching the cooking temperature.
3. The cooking oil should be at the normal (upper) oil-level line at cooking temperature.
Add or remove cooking oil as needed. All cooking oil should be melted before
proceeding.
4. Insert the fry vat probe into the cooking oil to within one (1) inch of the fryer
temperature-probe tip, approximately 3" (7.6 cm) below the surface. If using Pro Fry
computer display temperature PC # 326/327 or NCC #1540/1541, the computer probe
should be used.
5. Allow the vat to cycle ON and OFF three times.
6. After the stabilizing period, the instant vat cycles ON for the fourth time (as noted by the
fryer heat light turning ON) the cooking oil temperature should be within ±5°F (±3°C)
of the thermostat setting.
7. If it is within ±5°F (±3°C), calibration is complete.
8. If not, adjustments can be made by:
a.
Locating temperature control knob set screw.
b. Using a 1/8" (3 mm) flat-blade screwdriver, loosen the setscrew until the knob
rotates on the insert inside the knob. Rotate the knob on the insert CLOCKWISE to
INCREASE the temperature setting and COUNTER-CLOCKWISE TO
DECREASE.
c.
Carefully hold the knob and tighten the setscrew using the 1/8" (3 mm) flat-blade
screwdriver. Do not over tighten the setscrews.
9. Repeat Steps 1 through 9 for remaining fryers.
