ADJUSTMENTS
THERMOSTAT CALIBRATION GRIDDLE:
To Check Calibration
1. Turn thermostat to the 300°F of marking see figure 5.
2. After burners have been on a minimum of 1 hour (if cold)
or 30 minutes (if already hot when set at 300°F). Place a
reliable thermometer or therm-couple with test instruments
in the center of the griddle and over the center of each
burner. See figure 6.
3. Continue to check temperatures at 5 minute intervals, until
you have two readings that are within 30° of each other.
4. The control should only be recalibrated if your reading is
not within 30° of the dial setting (300°F).
TO RECALIBRATE THERMOSTAT:
This control has been carefully calibrated at the factory. That is, it is adjusted
to match the actual griddle temperatures. Field calibration is seldom necessary
and it should NOT be done unless considerable experience with cooking and
temperatures definitely proves that the control is not maintaining the temperatures
to which the dial is set.
1. When recalibrating, check temperatures as instructed in
previous section (thermostat calibration)
2. Set temperature indicator knob to 300°F marking
3. Remove indicator knob (Item "A") from thermostat
(Item "B"). Refer to figure 7.
4. Using a screwdriver knock out silver insert
(Item "C"). Refer to figure 7.
5. Place knob back on the thermostat shaft.
6. With screwdriver inserted through center
of dial and in the calibration slot of screw push in
and hold - DO NOT rotate screw.
7. Rotate indicator mark until it points to actual temperature you are reading off the temperature sensing
device you placed over the center of the burners.
8. Turn thermostat to 300°P and check temperature again at 5 minute intervals.
9. Remove indicator knob and reinstall center insert.
10. If the griddle will not adjust to within 30°F this means that the sensing bulb is inoperative and the control
should be replaced.
