OPERATION

HEATING INSTRUCTIONS

IMPORTANT: Never press the POWER SWITCH to FRYER unless the heating elements are

covered with shortening. Except for fryers equipped with the Solid Shortening Option, use
LIQUID SHORTENING only. Check shortening level marker inside the cooking basket for
proper shortening level.

NOTE: Except for fryers equipped with the Solid Shortening Option, the fryer is designed to
be used with LIQUID SHORTENING only. Lard and solid shortening will solidify in the filter
pump, causing pump failure.

1. WFAE-55FandWVAE-55F:
a. Set the TEMPERATURE CONTROL THERMOSTAT to 350° F.

b. Press POWER SWITCH to FRYER position. The contactor will close and the

HEATING ELEMENTS will start heating the shortening. The HEAT LIGHT will turn ON any
time the TEMPERATURE CONTROL THERMOSTAT is calling for heat and the HEATING
ELEMENTS are energized. NOTE: The first time the HEAT LIGHT goes out, the fryer is
ready to begin cooking.

2. WFAE-55FSandWVAE-55FS:
a. Program MENU KEY times and temperatures (see IOM Manual, p/n 300007).
b. Press POWER SWITCH to FRYER position. The controller will energize the HEATING

ELEMENTS until the shortening has reached the programmed temperature. The readout
will display "PRE" and "HEAT" and the selected MENU KEY, and the HEAT indicator will
be lit until the shortening has reached temperature. When the readout displays "00:00",
the fryer is ready to begin cooking.

COOKING INSTRUCTIONS

1. LOAD PRODUCT

a. Load frozen product into the BASKET. Using the plastic-coated handles, set the

BASKET on the LIFT CRADLE.

b. For fresh meat product, lower the basket and hand drop the product just above the oil

level to prevent splattering.

IMPORTANT: Different products contain different amounts of moisture, which will
cause the hot oil to foam. Determining the maximum safe load size that will prevent
hazardous overflow and splatter of hot oil. This can be accomplished by starting with a
small load, and gradually increasing the load size until the maximum load which can be
cooked without the oil foaming over the top of the frypot is reached.

2. WFAE-55FandWVAE-55F:
a. Set the TIMER for the time required to cook the particular product weight. Press the red

button in the center of the TIMER. The CRADLE LIFT will lower and the TIMER will start
counting-down. The COOK LIGHT will turn OA/when the cradle is fully lowered.
Turn the BUZZER SWITCH to ON.

b. At the completion of the timed cycle, the TIMER will reach 0, the BUZZER will sound and

the CRADLE LIFT will raise.

The BASKET and the cooked product will be hot.
Contact with hot cooked product can cause serious injury.

3. WFAE.55FSandWVAE.55FS:

a. Press the "BASKET" KEY followed by the "DOWN ARROW" KEY. When the cradle if fully

lowered, press the desired MENU KEY.
b. At the completion of the timed cycle, the cradle will rise and the sonalert will sound.

The BASKET and the cooked product will be hot.
Contact with hot cooked product can cause serious injury.

4. Use the plastic-coated handles to remove the BASKET and dump the cooked product into a

suitable tray or container.
