Frymaster Gen III LOV Installation, Operation And Maintenance Manual page 67

6.2.4 Clean around AIF and ATO sensors
1. Clean the sediment from around the AIF and ATO sensors during maintenance
filtration when the oil is drained from the frypot.
2. Use a screwdriver or other similar object which allows access around the probe
(see photo right). Use caution to ensure that the probe is not damaged.
3. Return the oil once the maintenance filtration is complete.
6.3 WEEKLY CHECKS AND SERVICE
6.3.1 Clean Behind Fryers
Clean behind fryers in accordance with the procedure detailed in maintenance requirement card.
To ensure the safe and efficient operation of the fryer and hood, the electrical plug for the 120-volt line,
which powers the hood, must be fully engaged and locked in its pin and sleeve socket.
6.3.2 Clean Filter Pan, Detachable Parts and Accessories
Wipe all detachable parts and accessories with a clean, dry cloth. Use a clean cloth saturated with a solution of
McDonald's All-Purpose Concentrate to remove accumulated carbonized oil on detachable parts and accessories.
Rinse the parts and accessories thoroughly with clean water and wipe dry before reinstalling. 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 M4000 Controller 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 controller displays "START" (indicating that the frypot contents are within the cooking range), press
the button once to display the temperature and setpoint of the oil as sensed by the temperature probe.
3 Note the temperature on the thermometer or pyrometer. Actual temperature and pyrometer readings should
be within ± 5ºF (3ºC) of each other after allowing the heat to cycle on and off three (3) times. If the temperature is
still out of tolerance, contact a Factory Authorized Servicer for assistance.
6.5 QUARTERLY CHECKS AND SERVICE
6.5.1 Clean the Frypot and Heating Elements
Never operate the appliance with an empty frypot. The frypot must be filled to the fill line with water or
cooking oil before energizing the elements. Failure to do so will result in irreparable damage to the
elements and may cause a fire.
6.5.2 Replace the O-rings
Refer to McDonald's MRC cards for specific details on replacing the O-rings on the filter connection.
