Frymaster 8196345 manual Melt Cycle Problems, Computer Malfunctions, Filtration Malfunctions

Improper temperature control problems can be categorized into melt cycle problems and failure to control at setpoint problems.

MELT CYCLE PROBLEMS

Initiation of the melt cycle with CM7 computers is automatic. Problems may originate from the computer itself, the temperature probe, or a malfunctioning heat relay on the interface board.

FAILURE TO CONTROL AT SETPOINT

Problems in this category may be caused by the temperature probe, the interface board, or the computer.

1.10.4 Computer Malfunctions

RECOVERY TIME

Recovery time – is a method of measuring a fryer’s performance. Put simply, it is the time required for the fryer to increase the oil temperature from 250ºF to 300ºF (121ºC to 149ºC). This range is used as a standard since ambient kitchen temperatures can affect the test if lower ranges are used.

The CM7 computer performs the recovery test each time the fryer warms up. An operator can view the results of the test any time the fryer is above the 325ºF (163ºC) point by pressing the INFO button once when the fryer is on. The test results will be displayed in the computer’s LED panel in minutes and seconds. The maximum acceptable recovery time for Protector® series gas fryers is two minutes and twenty-five seconds.

1.10.5 Filtration Malfunctions

The majority of filtration problems arise from operator error. One of the most common errors is placing the filter pad on the bottom of the filter pan rather than over the filter screen.

Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation of the filter pad, including that the correct size is being used. While you are checking the filter paper/pad, verify that the O-rings on the filter pan suction tube are present and in good condition. Missing or worn O-rings 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 reset. If the pump motor does not start, press the red reset switch located on the front of the motor. If the pump then starts, something caused the motor to overheat. It may be just that several frypots in a large battery of fryers were being filtered one after the other and the pump became 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 following reasons:

•Shortening that remained in the pan after previous filtering solidified in the suction tube recess in the bottom of the pan or the suction tube, itself. Adding hot oil to the pan and waiting a few minutes will usually correct this problem. A flexible wire can be used to clean out the suction tube and the recess in the bottom of the pan. NEVER use compressed air to blow solidified shortening out of the suction tube!
