3–3
CONTROLLER OPERATING PROCEDURE
1.
Verify that the thermostat knob is set to the desired cooking temperature.
2.
Press the power switch to the ON position. The POWER light will illuminate.
WARNING
Before pressing the power switch to the ON position, ensure that the frypot is
properly filled with oil. See Section 3.1.
3.
If the frypot temperature is below 180
°
F, the controller will automatically enter a warm-up cycle
(often called a melt cycle). The heating elements will cycle on and off repeatedly, allowing the
oil to heat gradually, without scorching. During the warm-up cycle, the heating mode light will
alternately illuminate and go off as the elements cycle on and off. Within about 45 minutes, the
controller will exit the warm-up cycle and the heating mode light will remain continuously
illuminated.
4.
When the oil temperature reaches the thermostat knob setpoint, the elements will cycle OFF and
the
HEAT
light will go off, indicating that the fryer is ready for the cooking process to begin.
HI-LIMIT TEST PROCEDURE
Tools Required:
One 0-600°F pyrometer with sensing probe or an equivalent high-temperature
thermometer.
NOTE:
Conduct this test when the fryer will not be needed for about one hour and when the
cooking oil is due to be changed (the test will ruin the cooking oil). Start the test with the controller
turned ON and with the cooking oil at normal frying temperature. Stir the oil thoroughly to ensure
even distribution and temperature.
DANGER
If the expected results (indicated by italics) for Steps 3 and 4 below do not occur,
turn off the fryer at the main circuit breaker panel and do not use the fryer until it has
been repaired by an authorized technician.
1.
Verify that cooking oil is at the bottom
OIL-LEVEL
line. Add oil if necessary.
2.
Turn the power switch ON and set the control knob to the normal frying temperature.
3.
Insert the pyrometer probe into the frypot so that its tip is near the temperature probe on the
element (i.e., approximately 1½-inch into the oil, near the center of the frypot). Press and hold
the high limit test switch in the “1ST” test position until the
TROUBLE
light illuminates.
Release the test switch.
The trouble light should have come on when the temperature was approximately 410°F (± 3°F)
and the heating elements should have de-energized (indicated by the
HEAT
light going out).
