SERVICE
WARNING: HOT OIL AND PARTS CAN CAUSE BURNS. USE CARE WHEN OPERATING, CLEANING OR
SERVICING THE FRYER.
WARNING: SPILLING HOT OIL CAN CAUSE SEVERE BURNS. DO NOT MOVE FRYER WITHOUT DRAINING
ALL OIL FROM THE TANK.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT
SWITCH TO INDICATE THAT YOU ARE WORKING ON THE CIRCUIT BEFORE PERFORMING ANY SERVICE.
CHECKING THERMOSTAT CALIBRATION
The fryer thermostat is carefully calibrated at the factory so that dial settings match actual frying compound
temperatures. Field recalibration is seldom necessary, unless the fryer has been mishandled in transit or
abused. Recalibration should not be resorted to unless considerable experience with cooking results definitely
proves that the control is not maintaining the temperature to which the dial is set.
1. To check frying compound temperatures when recalibrating, use a precision test instrument, or a good
grade mercury thermometer. Fill fry tank with frying compound to "FULL" mark.
2. Check frying compound temperature at the center of the tank, approximately 1" to 11/2" below surface of
frying compound.
3. Turn dial of thermostat being checked to the 350°F mark.
4. Allow temperature to stabilize, or until thermostat cycles to OFF three times after starting with cold frying
compound. With power ON, read highest and lowest frying compound temperature, as thermostat cycles
through at least two cycles. Average the reading.
5. Thermostat should be recalibrated if temperature reading is not within 10 degrees of the control knob
setting (350°F plus or minus 10°F). If recalibration is required, continue with steps 6, 7, 8 and 9.
6. Remove control knob by grasping outer edge and pulling straight out, without twisting or turning.
7. Hold thermostat dial shaft "B" (Fig. 1) stationary with pliers, and with a screwdriver, turn screw "A" (Fig. 1)
1
clockwise to obtain a lower temperature, or counterclockwise for higher temperature. Each /4 turn (90°
rotation) of screw "A" represents 18°F.
8. Replace thermostat control knob.
9. Recheck thermostat as in Steps 4 and 5 above. If the frying compound temperature is not within 20
degrees of dial setting (350°F plus or minus 20°F), it means that the sensing element is inoperative, and
the thermostatic control should be replaced.
