SERVICE PROCEDURES AND ADJUSTMENTS
TEMPERATURE CONTROL
CALIBRATION
NOTE: Ensure the griddle is level before performing
calibration as outlined under LEVELING in the
Installation & Operation Manual.
NOTE: Do not use an infrared thermometer for
measuring griddle surface temperatures. These
devices are highly sensitive to surface color (clean or
dirty), angle of reading and distance from the surface.
Use a temperature meter with surface probe for all
griddle surface temperature measurments.

1. Each temperature controller controls a 12" zone
of the griddle. Center point area of cooking zones
are located 6" from the side splash (left or right),
every 12" across the width of griddle, and 12"
back from the front of griddle plate.
2. Clean the center point areas of cooking zones to
ensure good contact with surface probe.
3. Set thermostats to 350°F and allow the indicator
light to cycle ON and OFF at least three times to
stabilize griddle surface temperatures.
4. Monitor indicator light for the temperature
controller calibration being checked. When the
light cycles OFF, measure temperature for that
zone and record.
• If tempereature measurement is 350°F ±5°F the
control is propererly calibrated.
• If temperature measurement is outside of
tolerance then temperature control must be
calibrated.
CALIBRATING TEMPERATURE CONTROL
Never adjust the screw on the back side
of the temperature controller. This will ruin the factory
calibration; the temperature controller will no longer
operate properly and will need to be replaced.
1. Use the temperature scale on the overlay as a
guide. Align the edge on a short piece of tape to
the temperature recorded in STEP 4 and apply
tape to knob as a reference point.
2. Remove knob from temperature control shaft. Do
not rotate the knob during removal.
3. Loosen screws on the back of dial. With knob
facing user, a clockwise rotation increases
temperature and a counterclockwise rotation
decrease temperature.
4. Hold the knob and rotate dial to the edge of the
tape used for reference. This adjustment offsets
the indicated temperature on the dial to the actual
temperature measured.
5. Hold the dial and knob together to maintain the
setting and tighten screws.
6. Install the knob back onto the temperature
control shaft.
7. Repeat "
TEMPERATURE CHECK." Adjust
calibration until temperature is within tolerance.
