Before You Plug In Machine
1. Make sure all machine switches are OFF before plugging equipment into receptacle.
2. Make sure wall outlet can accept the grounded plugs (where applicable) on the power
supply cord.
3. The wall outlet must have the proper polarity. If in doubt, have a competent
electrician inspect the outlet and correct if necessary.
4. DO NOT use a grounded to un-grounded receptacle adapter (where applicable).
5. Install unit in a level position.
CAUTION
If the supply cord is damaged, it must be replaced by Gold Medal Products Co.,

OPERATING INSTRUCTIONS
Controls and Their Functions
HEAT/MOTOR SWITCH
Two position, ON/OFF lighted rocker switch – provides power to the heating elements in
the bottom of the kettle, and powers the agitator motor to turn for 30 seconds of every
minute. The green switch light ON indicates there is power to these features.
Note: It is normal for the motor to stop for 30 seconds of every minute (when the Motor
Only Switch is OFF).
MOTOR ONLY SWITCH
Two position, ON/OFF lighted rocker switch – provides power to the agitator motor to
run continuously.
Note: The main function of this switch is for mixing the product/popcorn at the
end of the cooking cycle with the kettle in the tilt position, and it is used for
“cleaning mode”.
15 AMP FUSE
The 15 AMP Fuse protects the Motor and Heat Control from an overload condition.
KETTLE DUMP HANDLE
The Kettle Dump Handle tilts the kettle from the upright cook position to the mix position
or the dump position. The 2 position bracket holds the handle in the tilted position.

DIGITAL HEAT CONTROL
The Digital Heat Control adjusts the Set Point Temperature of the unit. The machine comes
from the factory preset to achieve a Product Cook Temperature of 280°F. See Digital Heat
Control Adjustment/Calibration section for adjusting the Product Cook Temperature.
D Models: The sound of the buzzer signals kettle heat shut-off. The buzzer will continue
to sound until the unit is turned off or until the unit temperature falls below set point.
DT Models: Dual Timer units. The pre-alarm sounds the buzzer 40°F before Set Point
Temperature; alerting operator that flavor can be added to the mix (the kettle will
continue to heat the mixture). The second buzzer sounds kettle heat shutoff at a Product
Cook Temperature of 280°F. Each buzzer only sounds for 10-15 seconds.
Buttons/Indicator Light Descriptions
UP Button / DOWN Button – adjusts the Set point Temperature UP or DN
when in programming mode.
Access Button – accesses programming mode to change Set Point Temperature, see
Heat Control Adjustment section.
Mode Button – exits programming mode and locks in adjustments, see Digital Heat
Control Adjustment section.
Digital Display – display shows temperature of the kettle; this is not the same as the product
temperature. (Reference the Digital Heat Control Adjustment/Calibration section.)
Heat Indicator Light – light is ON when the unit is heating. See image below for D Model
and DT Model indicator descriptions.
Buzzer Indicator Light – See image below for D Model and DT Model indicator light
description.

Digital Heat Control Adjustment/Calibration
Product Cook Temperature is the actual temperature of the PRODUCT (Caramel Corn Mix); this
is measured with an accurate candy thermometer. Infrared temperature readers are NOT
recommended.
Set Point Temperature is the temperature setting of the KETTLE; this is the temperature
needed to get the Caramel Corn Mix up to the finished Product Cook Temperature of 280°F. The
digital display shows the kettle temperature, NOT the product temperature.
Note: The Set Point Temperature will be higher than the product temperature.
Refer to the candy thermometer for accurate product temperature.
Digital Heat Control Adjustment
The machine comes from the factory preset to achieve a Product Cook Temperature of 280°F.
Small adjustments may need to be made for mix used or cooking conditions. If the product is
ready, either before or after the buzzer sounds, then follow the steps listed to increase or
decrease the Set Point Temperature of the kettle:
Note: D Models - The sound of the buzzer signals kettle heat shut-off.
DT Models – The sound of the second buzzer signals kettle heat shut-off.
1. To change the Set Point Temperature, press the key. The display shows SP
followed by a temperature number flashing. Use the arrow keys to set the desired
temperature.
2. Once the temperature is set, press the key to lock in the new temperature.
Digital Heat Control Calibration (Performed at the Factory)
This unit has been calibrated at the factory. Other than small adjustments made for mix used or
cooking conditions (see above Digital Heat Control Adjustment), the unit is ready for use and
should not need calibration.
To reset the Digital Heat Control back to factory settings follow the procedure shown below.
Note: For calibration purposes only, corn oil is used to determine the Digital Heat Control
temperature setting which will produce an accurate finished product temperature
of 280°F.
1. Start with a clean unit, which is cool before attempting to calibrate.
2. Fill the mixing bowl with a one inch depth of corn oil.
3. Turn the Heat/Motor Switch ON.
4. Use an accurate candy thermometer to measure the temperature of the oil in the
mixing bowl. (Infrared temperature readers are NOT recommended.)
