ADJUSTMENTS
CALIBRATION-900RX AND MSA MODELS
1. Each thermostat 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 burner to cycle ON and OFF at
least two times.
3. Watch for burner to cycle OFF, then measure
the temperature for that zone. The temperature
should be 350°F ±15°F. If not, continue to Step
4.
4.
a. Carefully loosen the knob set
screw. DO NOT allow the knob to
turn. Carefully remove the knob
from the thermostat shaft,
exposing the temperature dial.
b. Loosen screws on the temperature
dial and adjust to that the
temperature indicated by the knob
arrow matches the griddle plate
temperature reading. Knob will
have to be placed back on the
shaft to verify adjustment.
IMPORTANT: NEVER ADJUST THE
SCREW IN THE CENTER OF THE
THERMOSTAT SHAFT. This will ruin the
factory calibration; the thermostat will no
longer operate properly and will need to
be replaced.
5. Once calibration is achieved, tighten the
temperature dial screws and knob set
screws.
