Reconnect multi pinned plug and remount new multi-function board. Reconnect wire harness and close up control panel assembly. Reinstall (2) screws to secure panel mounting. SERVICE NOTE: Harness connectors, in split vat fryers, which serve the same purpose for left side or right sides, have been identified by a "red" dot for "left" and a "green" dot for "right". When reconnecting harness insure that red dots connect to left hand components and green dots to right hand components. B. OIL TEMPERATURE The fryer oil temperature is controlled by the multi function board, monitored by the thermistor probe and set by the potentiometer. The following calibration check will help determine the operational status of the temperature controller in the multi function board. NOTE: Best results can be obtained by not using new shortening. 1. The shortening must be at the proper level as indicated by the indicator line on the vat wall. 2. Insert pyrometer, at the rear of the fryer exactly where the computer probe would go. 3. Set the thermostat knob to the correct cooking temperature and turn on unit. 4. Allow the shortening temperature to cycle off after reaching the desired temperature. 5. Agitate the shortening using a maple paddle to eliminate the cold zone in the bottom of the kettle. 6. Stop agitating and allow fryer to cycle On and Off automatically three (3) times. 7. After the stabilizing period, the instant the element actuates (as noted by the fryer "On" light turning on), the shortening temperature should be plus or minus 5 F. (-15 C) of the thermostat setting. 8. If it is within ± 5 F. (-15 C) you are finished calibrating. 9. If not, loosen the set screw in the temperature control knob. Rotate knob without moving shaft and set the knob, to match the pyrometer reading. 10. Retighten the set screw. DO NOT OVERTIGHTEN. 11. Turn the dial to the desired temperature. 12. Repeat steps 6,7 and If, after repeating steps 6 thru 7 oil temperature calibration is not achieved, replacement of the multi-function board will be required. 14. Replacement of the multi-function board is to be performed only by a certified Vulcan service agency. Service personnel should disconnect unit power and follow board replacement procedure outlined in item 3 of melt cycle and temperature in Section II Service. HIGH LIMIT CONTROL The function of the high limit control is to shut the unit down in the event of a thermostat failure which would allow the cooking oil to be overheated. The operating temperature of the high limit control is 35 or 60 higher than the highest temperature allowed by the thermostat when the thermostat is functioning properly. In the event of a high limit 'Shut-Down" the entire control system will be put out of operation. DO NOT attempt to restart the fryer until the temperature of the cooking oil has lowered to approximately 350. CAUTION IF THIS SITUATION CONTINUALLY OCCURS, DO NOTATTEMPT TO BYPASS THE HIGH LIMIT. SHUT UNIT DOWN AND CONTACT A SERVICE AGENCY

12 SECTION II SERVICE (Continued) HIGH LIMIT TEST PROCEDURE This test is to be made in order to determine if the protection devices are properly functioning. (See steps 1 thru 9).
