INSTALLATION & OPERATIONAL SELV MANUAL
1 THEORY OF OPERATION
The Pitco Low (or reduced) Oil Volume fryer works very similarly to the Pitco standard electric fryer. Other than rotating elements (for cleaning), the units function nearly the same.
The Low Oil Volume Fryer has a reduced cold zone to significantly reduce oil usage and extend oil life. This smaller zone may require more frequent filtering depending on the product being fried.
Upon turning the fryer on, the high limit closes the (side on) safety contactor which stays closed until the fryer is turned off. If the oil temperature exceeds 450 deg F, the high limit opens and prevents further operation until the cooking oil has reached a safe cooking temperature. This places a minimum duty cycle on the safety (side on) contactor to insure its proper operation when needed. The “heat demand” contactor opens and closes on demand from the primary control to maintain the desired cooking temperature. When the “heat demand” contactor closes, it energizes the heating elements in the fry pot. Near the fryer heating elements, the temperature probe and high limit can be found. The temperature probe provides a signal to the primary control, sensing the oil temperature in the fry pot.
The fryer is equipped with a manual “ADD OIL” button that can transfer fresh oil from a JIB (Jug in Box) located under the fryer or a bulk oil management system. The operator can use the manual “ADD OIL” button as needed to replenish any oil consumed in the cooking process. It is recommended that oil only be added when the fry pot is at the desired temperature, and that the “ADD OIL” button not be used to fill an empty fry pot from the JIB.
Optional Automatic Top Off: If equipped, the fryer (only when operating at desired temperature) senses the oil level and replenishes consumed oil only between cook cycles. There are no programming options for the operator or service technician, the control functions like any other Pitco electric fryer computer control. The “ADD OIL” switch (described above) is present with Auto Top Off.
