ELECTRONIC THERMOSTAT
A. GENERAL - If the gas fryer is equipped with an Ultrastat 11, 21, or 25 Cooking Computer, NO maintenance is required on the
Temperature Sensing Probe. However, if the fryer is equipped with a Default-to-Manual-Restart (DTMR) Control, the Elec-
tonic Thermostat may need to be adjusted or calibrated according to the following procedure:
B. ELECTRONIC THERMOSTAT CALIBRATION - The Electronic Thermostat in all fryer configurations are equipped with a
Dial and Knob and should be checked and calibrated when necessary as follows:
1. ENSURE electrical power and, if applicable, gas to the fryer has been
turned OFF.
2. CAREFULLY drain sufficient shortening from the fryer to LOWER the
shortening about 4" (102 mm) beneath the Electronic Thermostat sensing
probe.
3. After the sensing probe has COOLED, loop the Sensing Element of an
ACCURATE digital test thermometer temperature probe around the
thermostat sensing probe; then connect the probe to the test thermometer.
4. Replace shortening drained in step 2 and ENSURE it is level with the short-
ening level mark on the rear of the vat; then turn the power and gas to the fryer ON.
5. Set the KNOB of the Electronic Thermostat to the CENTER (300) of the dial
and periodically STIR the shortening in a COUNTER-CLOCKWISE (CCW)
direction with a long handled skimmer to pull congealed shortening UPWARD
from the Cold Zone area.
6. When shortening has reached the preset temperature and the RED indicator lamp on the fryer has turned OFF, allow the
Electronic Thermostat to cycle ON and OFF about five (5) times to stablize the system.
7. After the shortening temperature has stablized, record the temperature reading of the TEST THERMOMETER immediately
after the RED indicator lamp and the fryer turns OFF.
8. CAREFULLY loosen the set screw on the Electronic Thermostat KNOB without turning the thermostat potentiometer, set the
thermostat knob pointer to the temperature recorded by the test thermometer; then tighten the set screw on the thermostat
knob taking care not to turn the thermostat’s potentiometer.
9. Repeat steps 1 and 2 above, remove the test thermometer sensing element from the Electronic Thermostat sensing probe;
then repeat step
4 to return the fryer to normal operation.
