17. problems arise from operator error One of the most common errors is placing the filter paper on the bottom of the filter pan rather than over the filter screen 3 25 Whenever the complaint is the pump is running but no oil is being filtered check the installation of the filter paper including that the correct size is being used While you are checking the filter pa per verify that the O ring on the bottom of the filter pan is present and in good condition A missing or worn O ring will allow the pump to suck air and decrease its efficiency If the pump motor overheats its thermal overload will trip and the motor will not start until it is re set If the pump motor does not start press the red reset switch located on the rear of the motor If the pump then starts something caused the motor to overheat It may just be that several frypots were being filtered one after the other and the pump got hot Letting the pump cool down for at least a half hour is all that is required in this case More often the pump overheated for one of the fol lowing reasons e Shortening was solidified in the pan or filter lines e The operator attempted to filter oil or shortening that was not heated Cold oil and shortening are thicker and cause the pump motor to work harder and overheat If the motor hums but the pump does not rotate there is a blockage in the pump Incorrectly sized or installed paper will allow food particles and sediment to pass t
