ADJUSTMENTS
CALIBRATION
1. Each temperature controller controls a 12” zone
of the griddle. Using a Surface Probe
temperature measurement device, observe the
temperatures at the center points of the
cooking zones. These points are located by
starting 6” from the side splash (left or right)
and every 12” across the width of the griddle,
with all points located 12” back from the front
edge of the griddle plate.
NOTE: Use of infrared thermometers is not
recommended. These devices are highly
sensitive to surface color (clean or dirty), angle
of reading and distance from the unit.
2. Set thermostats to 350°F and allow to stabilize,
allowing the indicator light to cycle ON and
OFF at least two times.
3. Watch for indicator light to cycle OFF, then
measure the temperature for that zone. The
temperature should be 350°F ±5°F. If not,
continue to Step 4.
4.
a. Set the temperature controller to
350° F. DO NOT allow the knob to
turn. Carefully remove the knob
from the temperature control
shaft.
b. Loosen screws on the back of
knob and turn the transparent ring
around the black knob to the
desired position. Knob will have to
be placed back on the shaft to
verify adjustment.
IMPORTANT: 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.
5. Once calibration is achieved, tighten the
knob screws.
