Frymaster H50 manual Disconnect power to the filter system

•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. 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!

•The operator attempted to filter oil that was not heated. Cold oil is thicker and causes 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 through the filter pan and into the pump. When sediment enters the pump, the gears can bind up and cause the motor to overload, tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with similar results.

A pump seized by debris or hard shortening can usually be freed by manually moving the gears with a screwdriver or other instrument as illustrated below. Make sure power to the pump motor is off before trying this.

1.Disconnect power to the filter system.

2.Remove the input plumbing from the pump.

3.Use a screwdriver to manually turn the gears.

•Turning the pump gears backwards will release a hard particle and allow its removal.

•Turning the pump gears forward will push softer objects and solid shortening through the pump and allow free movement of the gears.

Paper sized or installed incorrectly will also allow food particles and sediment to pass through and clog the suction tube recess on the bottom of the filter pan or the suction tube. Particles large enough to block the suction tube recess or the suction tube may indicate that the crumb tray is not being used.

Possible problems if a Power Shower is installed include clogged openings, shortening solidified in the tubes, missing clean-out plugs, and missing or worn O-rings. Cleaning the unit and replacing missing plugs and missing or worn O-rings will correct these problems.

The electronics of the FootPrint Pro system, illustrated in the schematic at right, are simple and straightforward.

Microswitches, which are attached to handles for each vat and wired in parallel, provide the 24 VAC required to activate the pump relay coil when the handles are moved to the ON position. The activated pump relay coil pulls in the pump motor switch, supplying power to the pump motor.
