High-Limit Check (With Thermostat Controller only.)

Note: Conduct this test when fryer will not be needed for about 1 hour, and when the cooking oil is due to be changed. Discard the cooking oil after completing this check

Note: Only one side of a split-vat is to be checked at a time.

Caution: Grease filters must be in place and exhaust fans must be ON during entire high- limit control check procedure.

1.The cooking oil should be at the normal (upper) oil-level line. Add cooking oil if necessary.

2.Remove the computer probe from the probe holder and replace it with fry vat probe.

3.Turn the vat power switch to ON and set thermostat knob to its highest setting, and wait for heating light to go OFF.

Caution: If after completing both high-limit tests you find only the second high-limit operates properly, the vat can be used if it is absolutely necessary, but with extreme care. The controller must be replaced immediately after this period of necessity. If the second high-limit does not work, the vat must not be used until the second high-limit has been replaced. If the first high-limit feature activates at less than 400°F (204°C), do not replace the controller unless it interferes with proper cooking. If the second high-limit activates at less than 425°F (218°C), do not replace it unless it prevents you from checking the first high-limit feature.

4.Press and hold "first high-limit" position of the vat high-limit test switch.

Result: Electrical element or gas burner turns OFF and "TROUBLE" light comes ON. Cooking oil temperature should be between 400° and 425°F (204° and 218°C).

5.Press and hold "second high-limit" position of the vat-limit test switch.
