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.

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.)

3–3
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.

3–6
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 REC 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.
