The fryer has two built-in high-limit protection features. If the temperature in the frypot reaches
approximately 410°F (210°C), the computer opens the heat relay circuit, turning the elements off. If
the temperature in the frypot reaches 450°F (232°C), a mechanical high-limit shuts off electrical
power to the elements. The operator should periodically test each of the high-limit protection features
to verify that they are operating correctly. Refer to Grills/Fryers Maintenance Requirement Card
(MRC) 15 for the procedure.
3.3 M-100B™ Computer Operating Instructions
WARNING
Before pressing the on/off switch to the ON position, ensure that the frypot is
properly filled with vegetable oil. See Section 3.1.
Operating the Computer on Full-Vat Fryers
0. Turn ON the cooking computer by pressing the right ON/OFF switch . A product name (for
example, FR FRIES) will appear in the right LED display.
0. If the frypot temperature is below 180°F (82°C), the computer will automatically enter a warm-up
cycle (often called a melt cycle). The heating elements will cycle on and off repeatedly, allowing
the vegetable oil to heat gradually, without scorching. During the warm-up cycle, the right heating
mode indicator will alternately illuminate and go out as the elements cycle on and off. Within
about 45 minutes, the computer will exit the warm-up cycle and the heat mode indicator will
remain continuously illuminated.
0. The M-100B computer allows the operator to use both sides of the computer if desired. By having
both sides of the computer on, the operator can select two products that have the same cooking
temperature, but different cooking times. Using a pair of twin baskets, both products can be
cooked at the same time.
0. To activate the left side of the computer, press the left ON/OFF switch . A product name will
be displayed in the left LED display.
0. Select the product to be cooked by pressing the right product selection switch (or, if both sides
of the computer are ON, the left product selection switch
) until the desired product is
displayed.
Once the frypot temperature is above 180°F (82°C), but still 15°F (8°C) or more below the setpoint
temperature for the product displayed (for example, french fries), the computer will alternately display
LOW TEMP and FR FRIES, and the right heating mode indicator will remain continuously
illuminated.
The cooking cycle cannot be started until the cooking oil is within ±15°F (8°C) of the programmed
setpoint. When the frypot temperature is within ±15°F (8°C) of the programmed setpoint, the product
name will be displayed continuously, indicating that the fryer is ready to cook the displayed product.
