SERVICE PROCEDURES AND ADJUSTMENTS
TEMPERATURE CONTROLLER
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 measurements.

CALIBRATION CHECK
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
thermostat cycle light to cycle ON and OFF at
least three times to stabilize griddle surface
temperatures.
4.
Monitor the thermostat cycle light for the
temperature controller calibration being checked.
When the light cycles OFF, record temperature
for that zone.
•
If temperature measurement is 350°F ±10°F
the control is properly calibrated.
•
If temperature measurement is outside of
tolerance then temperature control
must
be
calibrated.
CALIBRATING TEMPERATURE CONTROL
1.
2.
Loosen screws (2) securring knob guard to the
control panel for temperature controller being
calibrated.
3.
Loosen set screw then remove knob from
temperature control shaft. Do not rotate the knob
during removal.
Fig. 28
4.
Loosen screws on the temperature dial so the
dial will rotate.
5.
Install knob onto the temperature control shaft.
Do not rotate the knob during installation.
6.
Rotate temperature dial to match the
temperature reading. Hold dial in position and
remove knob. This adjustment offsets the
indicated temperature on the dial to the actual
temperature measured.
7.
Tighten dial screws.
8.
Install knob onto the temperature control shaft
and tighten set screw.
9.
Repeat CALIBRATION CHECK to verify
adjustment. Adjust calibration until temperature
is within tolerance.
