Automatic Lift Fryer Introduction
Specific Precautions
Risk of fire exists if the oil level drops 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 the life cycle of oil/shortening.
Do not open the drain valve or the fill valve while the fryer is under pressure.
Serious burns may result.
Follow operator instructions regarding effects of surge boiling of over-wet foods
and proper load size.
This unit may incorporate components that contain Mercury. The use of Mercury
relays is an industry standard.
Equipotential ground plane
When a high current flows through a conductor, differences in potential appear
between the conductor and nearby metallic surfaces near the appliance. As a
result, sparks may be produced between the appliance and surrounding metal
surfaces. These sparks could cause serious injury, damage, or fire.
BKI provides an Equipotential ground terminal for the connection of a bonding
conductor after the installation of the appliance per lEC60417-1. This terminal is
located on the inside of the Power Entry Supply box near the Earth connection
and is marked with this symbol.
Full Disconnection
In accordance with Local and/or National wiring codes, the installer must provide
a means of full disconnection under over voltage Category III conditions. An IEC
approved cord and plug combination will meet this requirement.
Units not provided with a cord and plug do not meet this requirement. In
accordance with Local and/or National wiring codes, the installer must provide
the means of full disconnection.
The fryer is designed to hold a maximum of 75 lb (34 kg) of oil/shortening.

Automatic Lift Fryer Operation
Care of the Shortening
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
expect an elapsed time of one hour or more between cooking, press the “0” button on the BLF-FC
model. On the BLF-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.
BLF-F Operation
Start-Up
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.
The fryer has a maximum temperature setting of 375º F/190º C (for BLF and
BLF-F) or 390º F/200º C (for BLF-FC). 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.
CS-TM-010.02 Revised 02/22/13

Automatic Lift Fryer Operation
3. 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
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.
4. 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.
5. Raise the basket to the top position by depressing the basket switch to the BASKET UP position.
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.
