ELECTRICAL REQUIREMENTS
The following power supply must be provided (reference unit Data Plate for Wattage requirement):
2181EL, 2181ER, 2181DEL, 2181DER: 120v/208v or 120v/240v, 60 Hz.
This unit is designed to operate on single phase, 20 AMP, 4 wire supply, 120/208 or 120/240 V~
(2 Hot, 1 Neutral, 1 Ground). All electrical components in this machine are 120 V (motors, heat
elements, lights, etc.) and therefore require “Hot to Neutral” connection (NOT “Hot to Hot”). A wall
receptacle is supplied with the machine. This receptacle will accept the attachment plug on the
machine and must be used.
DANGER
Machine must be properly grounded to prevent electrical shock to personnel.
Failure to do so could result in serious injury, or death.
Make sure all machine switches are in the OFF position before plugging the
equipment into the receptacle. Keep cord and plug off the ground and away
from moisture. Always unplug the equipment before cleaning or servicing.
DO NOT immerse any part of this equipment in water.
DO NOT use a water jet or excessive water when cleaning. 008_012221
A certified electrician must furnish sufficient power for proper machine operation and install any supplied
receptacle (reference unit Data Plate for model specific Volts AC, Hertz, and Wattage requirements). We
recommend this equipment be on a dedicated and protected circuit. Failure to wire properly will void the
warranty and may result in damage to the machine. It is Gold Medal Products Co.’s recommendation that
this machine be plugged directly into a wall outlet. The use of extension cords is not recommended due to
safety concerns, and may cause sacrificed and/or reduced performance. Make sure cord is located to
prevent a trip hazard or unit upset.
Receptacle Installation
A certified electrician must follow the IMPORTANT instructions below for installation of the
L14-20 Receptacle (Gold Medal Item No. 41254) provided with Model 2181 Series units.
If the receptacle is wired incorrectly, the heat elements/kettle and other electrical components could be at
208 or 240 V potential instead of the needed 120 V, resulting in excessive temperatures in the heat
elements (i.e.: kettle) and possible fire, and/or damage to electrical components.

Before You Plug In Machine
1. Make sure all machine switches are in the OFF position before plugging the equipment into the
receptacle.
2. Make sure the 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 the unit in a level position.
CAUTION
If the supply cord is damaged, it must be replaced by Gold Medal Products Co.,
its service agent or similarly qualified persons in order to avoid a hazard.

OPERATING INSTRUCTIONS
CONTROLS AND THEIR FUNCTIONS
HEAT SWITCH
This rocker switch in the “ON” position energizes the heating elements in the bottom of the kettle, and the
motor will also turn for 55 seconds of every minute. (It is normal for the motor to stop for 5 seconds of every
minute.)
MOTOR SWITCH
With this rocker switch in the “ON” position, the agitator motor will run continuously.
HEAT CONTROL (See below for Models with Digital Control)
The machine comes from the factory preset for product cook temperature for Pralinators. If more or less
heat is required, remove the silver hole plug or cover plate located on the front panel of the control box. This
will allow you to access the heat control adjustment potentiometer. Turn the potentiometer clockwise to
increase the temperature, and counter-clockwise to decrease the temperature.
To Calibrate the Heat Control for Product Cook Temperature: Fill the mixing bowl with a one inch depth
of corn oil. Use an accurate thermometer to measure the temperature of the oil in the mixing bowl. Stir the
oil while it heats. When the oil reaches 315F slowly turn the potentiometer counter clockwise until the
buzzer sounds. If the buzzer sounds before the temperature reaches 315F turn the potentiometer
clockwise until the buzzer stops and continue to turn an additional 1/8 of turn.
Note: The sound of the buzzer always signals temperature cut-off.
DIGITAL CONTROL
Steps to Change the Set point for the Machine:
1. To change the set point to the desired temperature, press the key. You will see 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 temperature.
To Calibrate the Digital Control for Product Cook Temperature: Fill the mixing bowl with a one inch
depth of corn oil. Use an accurate thermometer to measure the temperature of the oil in the mixing bowl.
Set the digital control set point to 400F, and turn the motor on to stir the oil while it heats. When the oil
reaches 315F, note the temperature displayed on the digital control and make that the set point.
NOTE: The set point will be different or higher than the cook temperature of the product.

PRALINATOR OPERATING INSTRUCTIONS
1. Make a solution of (3) parts water to (1) part Gold Medal imitation vanilla (Item # 4515). We
recommend making at least 1 gallon of this “vanilla water” solution. (1 qt. of item # 4515 + 3 qts.
of water.)
2. Measure 12 ounces for step 4, and 2-3 ounces for step 6.
3. Turn on the Pralinator heat switch, (leave the motor switch off) and add 2½ pounds of nuts. (Use
raw almonds, raw pecans, or roasted peanuts with skins removed. DO NOT use salted nuts.)
4. Add (1) 24 oz. package of Frosted Nut Mix, and 12 oz. of the vanilla water solution, and leave the
lid off the machine during cooking. (The lid is only to be used for cleaning.)
5. Allow to heat and mix until the buzzer sounds.
6. At the buzzer, the nuts can be finished two ways:
a. Spray on vanilla water until the buzzer stops to produce a consistent coat, with a
matte finish.
b. Pour on 2-3 ounces of vanilla water to produce a glossy, variable finish.
7. Dump the frosted nuts onto a cooling tray, separate, and allow to cool 10-15 minutes before
serving or packaging.
