3.1 Equipment Setup and Shutdown Procedures

Setup

WARNING

Fill the frypot to the bottom oil level line with vegetable oil before pressing the

ON/OFF switch to the ON position. Failure to do so could damage the frypot.

0. Fill the frypot with vegetable oil to the bottom OIL LEVEL line located on the rear of the frypot.

This will allow for oil expansion as heat is applied. Do not fill cold oil any higher than the bottom
line; overflow may occur as heat expands the oil.

0. Ensure that the power cord(s) is/are plugged into the appropriate receptacle(s). Verify that the

face of the plug is flush with the outlet plate, with no portion of the prongs visible.

0. Ensure that the vegetable oil level is at the top OIL LEVEL line when the vegetable oil is at its

programmed cooking temperature. It may be necessary to add vegetable oil to bring the level up
to the proper mark, after the oil has reached the programmed cooking temperature.

CAUTION

Do not add vegetable oil to the fryer between the time the computer is turned on and

the time it reaches programmed cooking temperature. Doing so is likely to cause

RECOVERY LOCKOUT (REC LOC). See Section 3.4.

Shutdown

0. Press the ON/OFF switch to the OFF position (the display will show OFF).

2. Filter vegetable oil and clean fryers.

3. Place the frypot covers on frypots.

3.2 Introduction To The M-100B™ Cooking Computer

The M-100B cooking computer, illustrated on the following page, automatically maintains fryer
temperature to cook products according to preprogrammed cooking specifications. The computer also
acts as a cooking process timer, displaying the remaining cooking time for each product and alerting
the operator by sound and display message to shake or pull the product at the correct time. It also
signals quality control (hold-time) limits. The computer automatically adjusts cooking times to
compensate for variances in product temperature and basket load so that, for example, a full basket of
cold fries will be cooked to the same quality as half a basket of fries at room temperature.

To quickly determine the software version number and the current configuration of an M-100B
computer, with the computer turned OFF (OFF in both displays) press the temperature check
switch. The displays will automatically cycle through the version number, power configuration (gas

or electric), EPRA configuration (On or Off), and frypot configuration (full- or split-).

The M-100B is factory-programmed with McDonalds’s cooking specifications for a group of seven
standard products. The cooking times and temperature settings for these factory-programmed products
can be changed by store personnel if required. Additionally, two test menus are available for store
personnel to program product names, cooking times, temperature settings, and shake or duty times for
products not included on the factory-programmed menu. The test menus can also be set to
automatically adjust the cooking rate to compensate for product variances.

For units equipped with built-in filtration, the computer times the polishing process and alerts the
operator when the polishing time has elapsed. (Polishing refers to circulating the vegetable oil
through the filtration system for a specified time.)

3–2

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

3.4 M-100B™ Computer Problem Condition Indicators

Open Drain Valve Indication

If, when the ON/OFF switch is pressed to the ON position, the display reads IGNITION
FAILURE, verify that the drain valve is fully closed. A drain safety switch built into the drain valve

assembly prevents the elements from being energized if the valve is not completely closed. After
verifying that the valve is fully closed, turn the computer OFF* for at least 5 seconds, then turn it back
on. If the message reappears, there is a problem in the electrical circuitry of the fryer or the computer;
contact your Frymaster Factory Authorized Service Center (FASC).

* On early-version M-100B split-vat units, BOTH computers must be turned off, even though the

problem condition may be associated with only one vat.

Low Temperature Indication

If the frypot temperature drops to more than 45°F (25°C) below the programmed setpoint temperature
during the cooking cycle, the cook switches will lock, the display will flash lOW TEMP and an

audible alarm will sound. If the frypot temperature returns to a range between 45°F (25°C) to 15°F
(8°C) of setpoint, the audible alarm will stop, but the cook switches remain locked and the display
alarm continues flashing. All functions return when the frypot temperature is within 15°F (8°C) of
the programmed setpoint.

Probe Failure Indication

If the temperature probe fails, the display will flash PROBE FAILURE and an audible alarm will
sound. To cancel the alarm, turn the computer OFF. In split-vat fryers, turn off the side in which the

failure occurred. If a probe fails during the high-limit test, PROBE FAILURE is displayed.
NOTE: If the temperature probe fails in the left side of a split-vat, that side cannot be turned back

ON once it has been turned OFF.

3–5

Recovery Out of Range (REC LOC)
Recovery time is an indication of the condition of the fryer. When the fryer is first turned on, the

computer records the amount of time it takes to heat the cooking oil from 250°F (121°C) to 300°F
(149°C). Also, anytime the temperature of the oil drops below 180°F (82°C), such as when cold oil is
added, the computer will check the recovery time. If the fryer takes longer than 1 minute and 40
seconds to recover, the display will show REC LOC and the computer will lock out.

To clear the REC LOC condition, enter the program mode (see How to Enter the Program Mode in
on page 3-10) and push the temperature check switch (see diagram below).

It is easy to view the currently recorded recovery time with the computer ON. Press the recovery
recall switch for the frypot you wish to check. On full-vat units, press the right switch.

If RE C LOC occurs three or more times within a week, verify that oil is not being added while the
fryer is heating (that is, while a heat mode indicator is illuminated) and that the fryer’s power cord

is fully plugged in. If oil is not being added while the fryer is heating, and the power cord is fully
plugged in, have the fryer checked by a qualified service agent.

CHAPTER 4: OPERATING FRYERS

WITH ANALOG CONTROLLERS

4.1 Equipment Setup and Shutdown Procedures

Setup

WARNING

Fill the frypot to the bottom oil leve l line wi th vegetable oil before pressing the power

switch to the ON position. Failure to do so could damage the frypot.

Fill the frypot with vegetable oil to the bottom OIL LEVEL line located on the rear of the frypot. This
will allow for oil expansion as heat is applied. Do not fill cold oil any higher than the bottom line;
overflow may occur as heat expands the oil.

Ensure that the power cord(s) is/are plugged into the appropriate receptacle(s ). Ve rif y that the fa ce o f
the plug is flush with the outlet plate, with no portion of the prongs visible.

Set the thermostat knob to the desired frying temperature.

Ensure that the vegetable oil level is at the top OIL LEVE L line when i t is at its intended cooking
temperature. It may be necessary to add vegetable oil to bring it up to the proper level.

Shutdown

1. Press the POWER switch to the OFF position (the POWER light will go out).

2. Filter vegetable oil and clean fryers.

3. Place the frypot covers on the frypots.

4.2 Introduction to the Analog Controller

The analog controller, illustrated on the following page, is used to adjust and maintain vegetable oil at
the temperature indicated by the thermostat knob. The fryer has two built-in high-limit protection
features. If the temperature in t he 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 op erator should periodically
test each of the high-limit protection features to verify that they are operating correctly. Refer to page
4-3, Analog Controller High-Limit Check, or the Grills/Fryers Maintenance Requirement Card (MRC)
15 for the procedure.

The analog controller has no timing features. Shake, pull, and QA (hold) times must be monitored by
the operator.

4.3 Analog Controller Operating Instructions

WARNING

Before pressing the power switch to the ON position, ensure that the frypot is

properly filled with vegetable oil. See Section 4.1.

1. Verify that the thermostat knob is set to the desired cooking temperature. For split-vat units, set

both knobs.

2. Press the power switch to the ON position. The POWER light will illuminate. For split-vat units,

both power switches must be placed in the ON position if both vats are to be used.

3. If the frypot temperature is below 180°F (82°C), the controller 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 heating
mode light will alternately illuminate and go off as the elements cycle on and off. Within about 45
minutes, the controller will exit the warm-up cycle and the heating mode light will remain
continuously illuminated.

4. When the vegetable oil temperature reaches the thermostat knob setpoint, the elements will c ycle

OFF and the heating mode light will go off, indicating that the fryer is ready for the cooking
process to begin.

4.4 Analog Controller High-Limit Check

Tools needed:

Maple Paddle

Note: Conduct this test when fryer will not be needed for about one hour, and when the vegetable oil

is due to be changed. Discard the vegetable oil after completing this check

Note: Check high-limit on only one vat 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 vegetable oil should be at the normal/shortening level line. Add vegetable 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.

4-3

Note: You must agitate vegetable oil during the entire high-limit control-check procedure with a

maple paddle.

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 " li ght comes ON. Ve get able oil

temperature should be between 400º and 425ºF (204º and 218ºC).

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

Note: When the trouble light comes ON, or the temperature exceeds 425ºF (218ºC), release switch.

Result: Electrical elements or gas burner turns OFF and the second high-limit will come ON. The

vegetable oil temperature should be between 425º and 450ºF (218º and 232ºC).

CAUTION

When the second high-limit light comes on, or the temperature exceeds 450°F (232°C),

release switch.

6. Turn the power switch to the “OFF” position. One vat must remain ON to ensure hood fan

remains ON.

7. Remove the fry vat probe and reinstall the computer probe into the vat.

8. Allow vegetable oil to cool for one hour before discarding. See statement on discarding oil

(Chapter 5).

Note: Hot oil must not be transported until it cools to 100°F (38°C) or less.

High-Limit check is complete. Repeat procedure for each remaining vat.
