Doughnut Fryer Installation Installation Serious injury, equipment damage or death could result if attempting to install this fryer yourself. Ensure that an authorized BKI service agent installs the fryer. Unpacking and Handling It is the owners’ responsibility to file all freight claims with the delivering truck line. Inspect all cartons and crates for damage as soon as they arrive.
Doughnut Fryer Installation Initial Test and Adjustment 1. Fill vat with shortening to about one inch below the mark. NOTE: A solid type vegetable shortening is recommended for frying because doughnuts tend to absorb more shortening and are heavy when fried in liquid shortening. Overfilling the fryer vat with shortening could lead to serious injury. Ensure that the fryer vat is filled with shortening only to the fill mark when shortening is hot.

Doughnut Fryer Operation Care of the Shortening Solid shortening should always be returned to the filter vat while in the liquid state. If this is not done, it will have to be heated to a liquid state. When using solid shortening, the fryer must be equipped with a pump heater. After filtering with solid shortening, the filter lines must be completely emptied of shortening. The pump heater will take care of any residual shortening in the pump, but cannot melt all of the shortening in the filter lines.
