cooking oil temperature exceeds 425º F, or if the HEATING ELEMENT is energized
without oil covering the top of the HEATING ELEMENT.
The HI-LIMIT SAFETY THERMOSTAT is reset by pushing the Red button after the
cooking oil has been allowed to cool.
3.
TEMPERATURE CONTROL THERMOSTAT: Controls the temperature of the
cooking oil by energizing / de-energizing the HEATING ELEMENT.
Set the Pointer to the desired cooking temperature marked on the panel.
The HEAT LIGHT will be ON any time the HEATING ELEMENT is energized.

OPERATION
HEATING INSTRUCTIONS
IMPORTANT: Never press the POWER SWITCH to FRYER unless the heating
elements are covered with liquid shortening. Check shortening level marker inside
the cooking basket for proper shortening level.
NOTE: 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.
Set the TEMPERATURE CONTROL THERMOSTAT to 350º F.
2.
Press POWER SWITCH to FRYER position. The contactor will close and the HEATING
ELEMENT will start heating the shortening. The HEAT LIGHT will turn ON any time
the TEMPERATURE CONTROL THERMOSTAT is calling for heat and the HEATING
ELEMENT is energized. NOTE: The first time the HEAT LIGHT goes out, the fryer is
ready to begin cooking.
COOKING INSTRUCTIONS
1.
Load product into the BASKET. Using the BASKET HANDLE, set the BASKET on the
LIFT CRADLE. Remove the BASKET HANDLE.
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.
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 ON when the cradle is fully lowered.
Allow the FRYPOT COVER to lower over the FRYPOT.
Turn the BUZZER SWITCH to ON.
3.
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.
4.
Use the BASKET HANDLE to remove the BASKET and dump the cooked product into a
suitable tray or container.

OIL FILTERING INSTRUCTIONS
DANGER
OIL MUST BE FILTERED WHILE HOT (300ºF AND HIGHER)
Contact with hot oil can cause serious injury including death.
Always wear protective clothing and insulated gloves when
filtering the cooking oil.
1.
Refer to the Installation, Operation and Maintenance Manual (p/n 301669) for complete operating
instructions for the filter system.
2.
The cooking oil must be hot (minimum of 300º F.) in order to filter properly. Cold oil will not flow
through the filter paper. Place the POWER SWITCH to the FILTER position.
3.
Insure that the FILTER SCREEN, FILTER PAPER,
and FILTER PAPER HOLDER are properly installed
in the FILTER RESERVOIR. Be sure the FILTER
SCREEN is installed under the FILTER PAPER.
NOTE: If the filter pump is not operating before
the DRAIN VALVE is opened, damage to the
FILTER PAPER will occur, resulting in the oil
flowing but not filtering.
DO NOT run the pump for more than 10 sec.
without oil flowing.
4.
Open the DRAIN VALVE. The WOOD DOWEL
may be needed to unplug the drain hole.
5.
While draining the oil, pour the FILTER
POWDER into the oil at the point where it
is being drawn down the drain.
6.
After all the oil has drained from the
FRYPOT, use the HI-TEMP BRUSH to
push breading crumbs and other debris
down the drain.

NOTE: use caution not to damage the two small CAPILLARY TUBES toward the front of the

7.
After 3 - 4 minutes of oil circulation, close the DRAIN VALVE and allow the FRYPOT to fill with the
freshly filtered oil. When all the oil has returned to the FRYPOT, turn OFF the FILTER SWITCH.
Turn the POWER SWITCH to the OFF position until starting to use the fryer again.
7.
Allow the FILTER RESERVOIR to cool before servicing. Refer to the IOM Manual (p/n 301669)for
complete FILTER RESERVOIR maintenance instructions.
NOTE: Refrain from using soap in the FRYPOT or FILTER RESERVOIR. Soap residue
will cause the cooking oil to breakdown rapidly.

1/4" ("Gortex") GASKET INSTALLATION PROCEDURE
CAUTION: Exposed electrical circuits.
Disconnect electrical power before attempting to replace
heating elements or thermostats.
The drawings below show top view of the Gortex Gasket and Belleville Washer installation
and nut tightening sequence.
STEP 1.
STEP 2.
STEP 3.
STEP 4.
STEP 5.
STEP 6.
Install the 1/4" Gortex gasket (p/n 66864) over the element studs.
DO NOT USE RTV! Insert the element through the frypot, element and
gasket on the inside of the frypot, and studs through the appropriate holes.
Install four 1/4" Belleville washers with the high center away from the frypot,
as shown in the drawing (4 places).
Install four nuts finger tight.
Using a torque wrench, tighten all four nuts 1/2 turn at a time. Working in a
cross pattern, tightening each nut in sequence until a uniform reading of
70 inch-pounds is achieved on all four nuts.
Wait 2 minutes and re-torque all four nuts to 70 inch-pounds.
Wait an additional two minutes and re-torque all four nuts to a uniform
70 inch-pounds.

1.
Insert the feed-thru bushing through the green gasket, and insert both through the frypot
wall. Slide the Belleville washer over the protruding threads of the bushing, with the high
centerofthe w asheraway from the frypot. Thread the locknut onto the bushing and
tighten. Torque the lock nut to 30 inch pounds.
Please Note: The 17mm. hex head feed thru bushing pictured at the left of the drawing
must not be rotated during the assembly procedure. Always support the bushing with a
box wrench while tightening the assembly to avoid damage to the green gasket.
2.
Slip the bulb of the capillary tube through the bushing. Mount the bulb to the center
portion of the element with safety clamps, positioning the clamps within 3/8”of the ends of
the widest part of the bulb. Route the capillary tube alongside of the element, but out of
the way of cleaning brushes, etc. Secure the capillary tube near the frypot end of the
element with a safety clamp.
Seat the washers and oil seal into the bushing. Insert the compresson nut into the
bushing, and torque to 30 - 40 inch pounds.
NOTE: Use care to not twist or kink the capillary.
