Wipe the filter pan and all detachable parts and accessories with a clean dry cloth. Use a cloth dampened with a
solution of McDonald’s All Purpose Concentrate to remove accumulated carbonized oil. Rinse and thoroughly dry
each part. DO NOT use steel wool or abrasive pads to clean these parts. The scratches that result from such
scrubbing make subsequent cleanings more difficult.
6.4 BI-WEEKLY CHECKS AND SERVICE
6.4.1 Check M3000 Computer Set Point Accuracy
1. Insert a good-grade thermometer or pyrometer probe into the oil, with the end touching the fryer temperature-
sensing probe.
2. When the computer display shows a series of dashes “----” or a product name (indicating that the frypot
contents are within the cooking range), press the
switch once to display the temperature of the oil as
sensed by the temperature probe.
3. Press the switch twice to display the set point.
4. Note the temperature on the thermometer or pyrometer. Actual temperature and pyrometer readings should be
within ± 5ºF (3ºC) of each other. If not, contact a Factory Authorized Service Agency for assistance.
