C24EO SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

TEMPERATURE CONTROL

CALIBRATION

To set the temperature control for optimum steamer
operation, the elevation above sea level for the
service location must first be determined. The
steamer was preset at the factory to sea level.

The elevation is used in conjunction with the
elevation table below, to determine the correct set 
point temperature for the control.

NOTE: If the set point temperature is too high, the
excess boiling action will cause water droplets to exit
the steam vent pipe, and cause high water usage.

1.

Remove right SIDE PANEL as outlined in
REMOVAL AND REPLACEMENT OF PARTS.

2.

Place a thermocouple approximately one inch
down in the center of steam vent pipe.

3.

Turn steamer on by selecting constant mode.

4.

Allow steamer temperature to stabilize by
completing two heating cycles.

5.

Record the temperature reading when cook light
goes out.

6.

Using the elevation table, compare the recorded
temperature to the temperature listed for the
specific elevation.

NOTE: Use temperature scale on control dial plate
for reference only. The scale represents dial turns in
1°F increments, not the actual temperature. When
calibrating, use the recorded temperature taken from
thermocouple.

A.

If the set point temperature of the control is
correct, no adjustment is necessary.

B.

If the set point temperature of the control is
not correct, adjust the temperature control.

1)

Turn the temperature control dial
clockwise to increase temperature or
counterclockwise to decrease
temperature.

NOTE: During temperature control adjustment,
display will blink on/off. When display reverts to a
steady image, that displayed temperature set point
has been "locked in" to memory.
