Resumen del manual
B. Verify drain valve is fully closed. Burner does not C. No electrical power to unit. C. Verify that unit is correctly plugged in and that circuit breaker is not tripped. light. D. No gas being supplied to unit. D. Verify that the gas line connections are properly connected, that any cutoff valves between the fryer and the gas main are open, and that the main gas cutoff valve is open. 6.4 Troubleshooting the Built-In Filtration System PROBLEM PROBABLE CAUSES CORRECTIVE ACTION Unit will not go into melt cycle or stays in melt cycle continuously. Failed melt cycle switch. Melt cycle switch must be replaced. Call FASC. Fryer never reaches frying temperature. Failed thermostat or thermostat out of calibration. Isolating the problem requires additional troubleshooting beyond the scope of operator troubleshooting. Call FASC. Pump won’t start. OR Pump stops during filtering. A. Thermal overload switch has tripped on an overheated motor. Test: If the pump stopped suddenly during the filtering process, especially if after several filtering cycles, the pump motor has probably overheated. Place the filter handle in the OFF position, allow the pump to cool for at least 45 minutes, and then press the reset button on the pump motor. Attempt to activate the pump. A. If the pump runs normally after resetting the thermal overload switch, the pump was overheated. Always filter with the cooking oil/shortening at or near frying temperature. Allow the pump motor to cool off for about 10 minutes after filtering two full frypots one after the other. Check the filter paper after each frypot is filtered. Replace the paper if there is a large accumulation of sediment. 6-4 CF SERIES GAS FRYERS CHAPTER 6: OPERATOR TROUBLESHOOTING 6.4 Troubleshooting the Built-In Filtration System (cont.) PROBLEM PROBABLE CAUSES CORRECTIVE ACTION Pump won’t start. OR Pump stops during filtering. (cont.) B. Failed filter handle microswitch. Test: If this is a multi-pot fryer, attempt to operate the pump using a different handle. If the pump starts, the handle microswitch is out of alignment or has failed. When the handle is placed in the ON position, the lever on the microswitch should be firmly pressed against the switch. If so, the switch has failed. If not, the switch is loose and/or misaligned. B. If the switch is loose, tighten the screws holding it in place, ensuring that when the handle is placed in the ON position, the lever on the microswitch is pressed firmly against the switch. If the switch has failed, call FASC. C. Pump blockage. Test: Close the drain valve. Place the filter handle in the OFF position, allow the pump to cool for at least 45 minutes, and then press the reset button on the pump motor. Pull the filter pan from the unit and then activate the pump. If the pump motor hums and then stops, the pump is blocked. C. Pump blockages are usually caused by sediment build-up in the pump due to improperly sized or installed filter paper and failure to use the crumb screen. Call FASC to have blockage cleared. Ensure that filter paper is of the proper size and is installed properly, and that the crumb screen is used. Pump starts, but no transfer takes place or the transfer is very slow. A. Oil/shortening is too cold for filtering. A. To properly filter, the oil should be at or near 350°F (177°C). At temperatures lower than this, the oil becomes too thick to pass through the filter medium easily, resulting in much slower oil return and eventual overheating of the filter pump motor. Ensure that the oil is at or near frying temperature before draining into filter pan. 6-5 CF SERIES GAS FRYERS CHAPTER 6: OPERATOR TROUBLESHOOTING 6.4 Troubleshooting the Built-In Filtration System (cont.) PROBLEM PROBABLE CAUSES CORRECTIVE ACTION Pump starts, but no transfer takes place or the transfer is very slow. (cont.) B. Improperly installed or prepared filter pan components. Test: Close the drain valve. Move the filter handle to the OFF position, pull the filter pan (and Power Shower, if so equipped) from the unit. Move the filter handle to the ON position. If a strong stream of air is being pumped out of the oil return port (or the Power Shower port), the problem is with the filter pan components. B. Remove the oil from the filter pan and replace the filter paper, ensuring that the filter paper support screen is in place under the paper. If this does not correct the problem, the filter tube suction tube is probably blocked. Remove the blockage using a thin, flexible wire. If unable to remove the blockage, call FASC. C. Improperly installed or prepared filter pan components. C. Verify that filter connection O-rings are present and in good condition. Replace the filter paper, ensuring that the filter paper support screen is properly positioned under the paper. A. Plugged openings or solidified shortening in the Power Shower. Test: Look for oil squirting out around the Power Shower gasket. If so, Power Shower is obstructed. A. Clean the Power Shower per instr...
