Gas Pressure 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. The pump heater accessory may be purchased separately from BKI.
To extend the life of your shortening, for the best possible flavor in your products, and for economy and efficiency of operation, we urge you to follow these recommendations:
1. Use only high-quality frying shortening without additives, of low moisture content and with a high smoke point.
2. Press excess moisture from products before breading. The more moisture released in the shortening, the quicker it will break down.
3. Filter at least once a day or once every three loads during frequent cooking.
4. Clean any residue or crust formations from the sides and bottom of the pot each time you filter the shortening.
5. Add fresh shortening as needed to maintain the proper shortening level TO THE FILL MARK ON THE POT WALL.
6. DO NOT HOLD SHORTENING AT HIGH TEMPERATURE when the fryer is not in use. If you expe ct an elapsed time of one hour or more between cooking, close the lid and pre ss the “0” button on the LGF-FC model. On Models LGF and LGF-F, set the thermostat to 150º F.
7. Shortening changes are determined by the quantity and type of food prepared. Excessive boiling and foaming are definite signs of shortening breakdown.
8. After you have finished frying for the day, filter the shortening and replace the filter pad. Also, thoroughly clean the pot of sediment and crumbs and empty the condensate pan.
LGF and LGF-F Operation
Start-Up (LGF and LGF-F)
1. Make sure the main drain valve is closed.
2. Fill pot with shortening to about one inch below the fill mark.
Risk of fire exists if the oil level drops below the minimum oil level. The level of oil within the pot must not fall below 5mm of the maximum oil level.
Use of oil/shortening older than the manufacturers recommendations for life of the oil is prone to surge boiling and flash fires. Follow the oil manufacturers guidelines for lifecycle of oil/shortening.
Overfilling the fryer pot with shortening could lead to serious injury. Ensure that the fryer pot is filled with shortening only to the fill mark when shortening is hot. Do not use any shortening other than what is specified in this manual and do not overfill the fryer pot.
15
Gas Pressure Fryer Operation
The LGF/LGF-F fryer has a maximum temperature setting of 375º F (190º C). Do not use oil/shortening with a flashpoint less than 554º F (290º C)
Use only high-quality shortening that has low moisture content, a high smoke point and no additives.
3. Place the gas control ON/OFF switch in the ON position.
4. The digital timer has a STIR OIL function that operates in one of four reconfigurable modes. If the timer needs to be reconfigured, follow step a. If the timer does not need to be reconfigured, follow step b.
a. Press and hold the ALARM button and at the same time place the FILTER/OFF/FRY switch in the
FRY position. The display will show the word “STIR” until the ALARM button is released. When the button is release the display will show the current configuration mode. To change this mode select the timer key that represents the mode you want. Refer to the table below:
KEY DISPLAY MODE DESCRIPTION
A -AL­B -OFF
C PrES STIR OIL function for all Pressure Fryers. D LiFT STIR OIL function for all Autolift Fryers.
The display will now show the selected mode. Proceed to step c.
b. Once the fryer is filled with shortening, place the FILTER/OFF/FRY switch in the FRY position.
c. Unless the STIR OIL function is operating in the –OFF mode, the digital timer activates a STIR OIL
function and begins an internal six minute countdown (not displayed). At the end of the internal countdown, the display shows the words “STIR” then “OIL” in .5 second intervals and the alarm sounds. Depress the ALARM button and stir the shortening freely while it is heating.
IMPORTANT! Before the first cooking operation each day, stir the shortening freely while it is heating to provide a balanced shortening temperature for excellent results with the first cooking. Failure to do this can result in a crusty skin on the product surface with an undercooked product internally. In addition, in some cases, failure to stir the shortening while it is initially heating may cause the HI-LIMIT safety device to disable the power due to a false overtemperature condition.
5. Set the thermostat to the desired cook temperature. The temperature light will go on. When the temperature is reached, the light will go off. The light will continue to cycle on and off as the fryer maintains the set temperature.
6. Press and hold the TIME SELECT arrow buttons on the digital timer until the desired cook time is displayed or recall a preset time by quickly pressing the appropriate preset button.
7. The shortening will heat and begin to reach the fill mark inside the pot. Add more shortening as required to reach the fill mark.
New or unchanged timer. Alarm sounds at the end of the internal 6 minute countdown. Defeats the STIR OIL function. Timer operates as if it had no STIR OIL function.
Cooking (LGF and LGF-F)
Do not open the drain valve or the fill valve while the fryer is under pressure. Serious burns may result.
1. Ensure that the Start-Up procedures have been performed.
