5 Equipment alert

Be extremely careful during this procedure.

Test the first (internal) high- limit control.

If you decided to test a full vat or the right-hand side of a split-vat, press the right cook channel button marked “1” and hold it until the heat indi- cator button lights up. This shows the fryer is calling for heat.

If you decided to test the left- hand side of a split-vat, press the left cook channel button marked “1” and hold it until the heat indicator button lights up. This shows the fryer is calling for heat.

The right display will alter- nate between displaying “Hi- Limit” and the current oil temperature until the tempera- ture reaches 410°F (210°C). When the temperature reaches 410°F (210°C), the display will alternate between “Hi-1” and the current temperature. The heat indicator light will go out. If you see these things, the control has passed the first test.

If the display alternates be- tween “Hi-1” and “bad,” the control has failed the test.

When the test is finished, reset the computer by press- ing the on/off key to turn the computer off, and then press the on/off key again to turn the computer on.

6Test second (mechanical) high-limit control.

If you are testing a full vat or the right-hand side of a split- vat, press and hold the right cook channel button marked “2.”

If you are testing the left-hand side of a split-vat, press and hold the left cook channel button marked “2.”

The display will alternate between “Hi-Limit” and the current oil temperature until the oil temperature reaches 425°F (218°C). At that tem- perature the display should show “Hi-2.” If it shows “Hi- 2” at that temperature, the control has passed the test.

If the display alternates be- tween “Hi-2” and “bad,” the control has failed the test.

Press the on/off button to clear the second test and turn the computer off.
